Prosto D/C Power:
* main conversion of AC to DC cuts the amount of heat lost and increases efficiency. Less power lost, less heat generated .

* Simpler power supply units (PSU) mean less chance of a PSU failure in a server, cutting maintenance and redundancy costs.

* A single standard (DC) for both live power and battery power.

* Lower cost for servers and other equipment, once it is mass-produced.

1. wat is your name?
2. Wrong with the Tesla coil i have created the energy going through the coil multiplies rapidly while passing through giving much more power and this only works with AC
3.DC Costs much more because of all the machines that are continually needed to be replaced.

Hello my name is George Westinghouse and I am in favor of AC power. AC can power very long distances quickly and efficiently. DC is only good for powering short distances. My AC was used to power tunnels and bridges. DC could only power cities where people lived close together, where AC could do that as well as large areas. For example my AC was used to Power the Chicago World’s Fair, which is a small area. The Brush Arc Lighting Company which also supports AC was Chosen to power large parts of New York City. Edison knew my power was better but refused to admit it. To try and make AC look bad he published an article talking about all his tests which made AC look bad, but his tests were rigged so AC would fail and look bad.
Many companies also chose AC power, such as the Manhattan Elevated Rail-Road Company of New York. Edison began testing with AC power to see how it would be better, and he discovered that AC used less electricity than DC making it cheaper. So being able to travel further distances, power more stuff, and for cheaper defiantly makes AC better.

Hi, my name is E. H. Howard and I am Thomas Edison's assistant. I strongly support direct current power for many reasons. Direct current is safer, and not as harmful to living things as alternating current is. To power direct current, coal is used, so the cost varies on how much coal costs at that time. The voltage of direct current weakens as it runs through copper wires longer so more power is lost, the longer the electricity has to travel through the wires. When humans came in contact with it, they could barely feel 8 volts while when they came in contact with the alternating current, two volts was the most they could handle without pain. The voltage has to be generated at the level that the load requires, so if the load is 10 volts, then the voltage of direct current generated has to be ten volts. The resistance becomes less when it runs through a thicker wire. An environmental concern would be the pollution of the coal. But also, the usage of coal, will boost the buying of it, therefore boosting the economy. Direct current is used for many things, including for the lights in shops and business and to wire homes.

Thomas Edison (AS)

Hello. My name is Thomas Edison, the great supporter of direct current powering the United States. Direct current has been powering parts of the United States for many years and was made specifically for the incandescent light bulb, which is replacing thousands of gas lamps each day. Direct current is cheap when more loads are added, so it will fare well in the economy. The typical voltage of a direct current generator is 110 V-220 V which is more safe than an AC voltage (1000 V). Direct current can be operated by a battery and is the only type of current that can be held in a battery storage device. DC power doesn't introduce reactance in the line, resistance of any kind, and only deals with real power, unlike AC power. Think DC power is relative to a continuous flowing river, but AC power is like a river moving back and forth therefore creating more resistance that would have to be monitored by many people unlike DC power which doesn’t need to be monitored as closely. DC power may not be more efficient, but it can power more objects, such as a motor, more quickly and easily than a similar AC motor. To this very day, a light is much better off with DC power. Also, many appliances that require batteries run on DC, since AC requires a large voltage and a transformer, whereas DC power requires a small power source and maybe a resistor. DC power can be used to power public transportation and railway cars.

DC is simpler to use and is used in most motorized electronics as well as telephone companies. To this very day, I can guarantee that a telephone company would rather go to bankruptcy than convert to a complicated AC system. On a larger scale, DC power can be used to transmit higher voltages over a longer route because it is easier to monitor and offers less resistance as demonstrated in an Italian town which successfully powered the country side. AC power gives in to the “skin effect” which is when the electrons will attract to the insulator creating heat. This effect actually makes AC power have a larger transmission carbon footprint. In order to prevent this from being discovered, AC power distributors put a high voltage in the system. In a recent demonstration, a prisoner was electrocuted by DC power and took a long time to die, but AC power killed another with one shock. This shows that AC power is much more deadly than DC power. Direct current wires are buried underground and can serve many people to one generator, as it has done for years in New York City. AC power lines are made above ground, and even though they are less expensive, they are more open to risks of shortages, arcing, and wire breaks which can lead to the deaths of its very users. A case of overhead wires breaking was recorded a few months ago and it killed many people.

I implore you to stop using AC power, as it is detrimental to our society. I implore the people of the United States to consider the fact that DC current is safer, environmentally friendly, easier to monitor and use, and is better for the common people in general. DC power offers no reactance, resistance, voltage drop, or susceptance (giving a higher voltage) and requires less calculations, conductors, and insulation. AC power is relatively expensive over long distances, requires more maintenance and people working to monitor many things, and cannot make the current life easier. I implore you to stop the foreign-based method of AC power because it is simply not American, which is what we are trying to fight. DC power is the future of different ways to electrify the bulk of the nation and move forward. That, my friends, is the dream of the average worker, the government, and common population.

Thomas Edison (AS)

1/30/2011 07:49:18 am

I would also like to add that many citizens support DC power for its reliance, rather than AC power which is more dangerous. Tests on animals have shown that AC current is much more dangerous to humans than DC current. It is known that the United States government's main concern is for the safety of the people which is the main reason why this great nation was founded. Ask yourselves this question without any bias, "Do I want to jeopardize safety for innovation?" DC power is more efficient, as it doesn't need transformers or any complicated materials like AC power does. I think I can speak for the workers in coal mines and copper factories who are what keeps the economy running today (1890). They are the ones who will be effected by a change to AC power, since most are specialized in certain areas of their work. Because of them, coal prices are cheap and are affordable for other things that use coal as power such as the train system. Think about the thousands of coal workers who will be abandoning their jobs because of this possible switch to AC power. The government must look over the advantages and disadvantages to each power type and think about the people who power the economy, trade, and the nation. That is what I leave you with to consider.

Hello, my name is Paul Carrington; I am a Governor representative for Virginia. I support direct current because its been around for many more years than alternative current, its also widespread across the United States. Direct current is safer and simpler to use. It travels longer distance at a high voltage. Direct currents voltage is around 110-160volts. Alternative current is much more dangerous and it has higher voltages, which it is also harmful to people, animals and nature. Direct current is using coal and copper to power it, which it helps miners to keep their jobs. I believe that direct current is better for everyone.

Thomas Edison(AS)

1/30/2011 11:14:58 pm

I do agree with Mr. Carrington who makes completely valid points about the advantages of DC power over AC power. I would also like to add that AC power requires hydroelectric engineers which would mean that the less educated coal miners, not only would lose their jobs, but also have nowhere to go. The Niagara Falls hydroelectric plant could also be converted to a tourist destination, probably making about the same amount of money over time as it would generating electricity. This is mainly because the falls would need hundreds of millions dollars just to get it started and it would need millions invested in maintenance. And why would we ruin the splendor of this site of beauty with dangerous overhead wires, turbines, and dams that would threaten wild life. DC power requires less materials and is environmentally friendly.

Nikola Tesla (BJ)

1/30/2011 11:17:59 pm

AC should be Americas power supply because AC is powered by Hydroelectric turbines that send electricity through wires to places where they need it AC is not dangerous it is if used dangerously there are ways to make it safe and ways to make it dangerous. AC power can be used to electrocute people but it is used in that way if you use AC properly then it is not dangerous.

AC power was used to harness the power of Niagara Falls which powers most of Chicago and many places in New York. AC power was also used to power the Chicago world Fair the first all electric fair it was a great success. I used the polyphase technology to gain 40 patents, therefore I locked in my rotating magnetic field principles and created a polyphase power distribution into a understandable system for the generation, transmission, distribution, and utilization of AC power.

Thomas Edison (AS)

1/30/2011 11:21:08 pm

In response to Nikola Tesla’s posting, I say that AC requires much more maintenance and monitoring; therefore, creating a large amount of wasted money and working hours. The average AC power generator requires several scientists monitoring the probabilities rather than the real numbers. And with damages of overhead lines and the problem with the synchronization of electricity grids, AC power today (1890) requires much more effort put into it. DC power is simply a flowing river of electrons that doesn’t need to be monitored closely because DC power deals with real numbers. And even though the generator serves less people, we provide a much more stable, reliable, and economically better electricity.

Bill Brown (KS)

1/30/2011 11:23:07 pm

Hi, my name is Bill Brown and i am a copper miner. I am for direct current for many reasons. One reason is that Ac power use smaller copper wires. With that, the price of copper goes down and that makes many miners lose their jobs and mines could shut down. Dc power has also been around longer than ac. Ac has a very high voltage making it more dangerous than dc, which has 110-160volts. I think that dc power is better for almost everyone.

Thomas Edison (AS)

1/30/2011 11:26:48 pm

Nikola Tesla fails to realize that AC power is much more dangerous than DC power because of easily breakable overhead power lines. The overhead power lines can easily arc, creating a shortage in the bidirectional flow of AC electricity. This can be hazardous and a nuisance to those who require constant electricity. I do agree that electricity can be used to harm people intentionally, but AC power does have a higher chance of heart stopping electrocution than DC power. DC power lines are buried underground; therefore, it makes the public more safe from the dangers of overhead power lines which carry a deadly 1000 V.

Edison't Assistant (ED)

1/30/2011 11:33:56 pm

Disagreeing with Nikola Tesla’s observations, alternating current is very hard to maintain, which means there is a greater chance of it electrocuting people and causing immediate death. Alternating current was tested on dogs, and it was found that it killed the dogs in one- tenth of a second, while direct current showed no physical difference in the animal and killed them after a few minutes. That means that direct current would be a lot less painful than alternating current.

Edison's Assistant

1/30/2011 11:36:45 pm

I believe Paul Carrington’s observations are true and I support the use of coal because it will create much needed safety of the miners’ jobs and will boost the economy. Fewer deaths will be the result if we choose direct current over the much more dangerous alternating current. While testing direct current, we found that when people were exposed to a bare eight volts of direct current, they could barely feel it. But when they were exposed to a mere, two volts of alternating current, that was the most they could handle without being in great pain.

I agree with Tesla, AC power is much safer therefore making it better to have in common homes.

George Westinghouse (TM)

1/31/2011 08:29:39 am

Also in response to Edison's assitant, you said that DC weakens as it travels further. How is this a good thing? AC maintains the same amount of power throughout which makes it better.

Thomas Edison (AS)

1/31/2011 11:24:24 am

I disagree with Westinghouse's response to Nikola Tesla. It was shown through several tests that AC power kills animals much more quickly and effectively than DC power. This applies also in the recent electrocutions of death row prisoners (the one electrocuted by AC power was killed instantly at a lower voltage, whereas DC power didn't kill another prisoner as quickly and it took a long time). If one were to be electrocuted by an overhead AC power line, he or she would be killed instantly. If one was to be electrocuted by an underground DC power line (which would be unlikely), he or she will have a chance to survive since they have more time to live and therefore a larger chance of survival. DC power is, in fact, much more safer than AC power.

Thomas Edison (AS)

1/31/2011 11:41:11 am

Many would argue that AC power lines can be buried underground. However, the cost of this for AC power companies would be enormous, since that type of power requires a much higher voltage to be generated, hundreds of scientist working to monitor it, and transformers every 100 ft and therefore, a higher cost. High Voltage Direct Current experimentations in countries all over the world can carry a small voltage 100s of km because DC power doesn't offer many things that reduce the voltage of the current unlike AC power. These experimentations do not require generators to be installed every few km and can power the future of America whereas AC power can't even provide safe power transmission.

Senator (TC)

2/1/2011 03:04:03 am

Neel the cost of DC is way more than AC. DC has to use many machines to get their electricity. Where as AC uses way more resoures than DC. Such as copper and cheaper electricity. So how did you get DC to not cost more? Also you should put your name on who you are.

Senator (WM)

2/1/2011 03:11:03 am

In response to Mr. Edison, could AC power killing faster not be a good thing? You addmitted that AC power can go to higher voltage and is therefore more effective. You also said that the amount of power in AC is higher and “more dangerous”. Could this power not be contained. If not currently then sometime maybe in the near future. I would love to hear your thoughts on the matter.

Senator (TC)

2/1/2011 03:19:56 am

In refrence to George Westinghouse why didn’t you say how does AC works? And you are saying AC is so great, but what about how AC is more dangerous than DC. This is so because of the voltage is higher in AC than DC. Making it more dangerous for people to handle AC. And why did you not include hydroelectric power in when you are saying AC is so great. Are you saying that hydroelectric power isnt a big part of AC?

Senator (WM)

2/1/2011 03:25:48 am

To whomever Neel Patel is supposed to be. I was unclear as to your views. But I will say that DC power is MUCH more expensive than AC due to all the natural resources, such as copper and coal. DC power is much less powerful and effective over distance compared to AC. You might want to bring the ethics of laying off the copper and coal miners. But a company has to keep itself in buisness before others.

Senator (TC)

2/1/2011 04:38:33 am

In response to Edison’s assiant what would happen to the coal miners jobs if DC won over AC power? Are you willing to take the risk of peoples health with the pollution that DC gives off? That is a big risk, is there any other ways that you could some how stop or lower the pollution of DC? You should also explain the diffrences between DC and AC. This would help people get a better understanding of the topic.

senator (TC)

2/1/2011 04:51:50 am

In response to Thomas Edison why is a light bulb better with DC? Please explain your reasons more in detail. Why do you guarentee that a phone with AC would go bankrupt? Why is it bad that AC killed the prisoner with one shock? Wouldn’t it be a better thing? Because it would be a shorter and less painful death? Why are the AC wires less expensive than DC? You should be stating these deatails as you metioned them

Senator (WM)

2/1/2011 04:52:33 am

Mr. Tesla, you say that AC power is not dangerous when used safely. How do you safely use AC power? And if you were so sincere on safety then why are your power lines above the ground? You also mentioned that AC “harnessed the power” of Niagara Falls. How did it do that? And how much did that cost?

Senator (WM)

2/1/2011 04:58:30 am

Mr. Westinghouse, you said that AC is better to have in common households. This is partly true, but your AC power is notoriously dangerous. It runs above ground instead of under like DC. This makes it much more dangerous, does it not? And it is also proven to kill faster. In an accident this could be a lethal problem. Does this sound like something you would want in your house?

Senator (TC)

2/1/2011 05:00:44 am

In response to bill brown why does it matter if DC has been around longer? Please explain why this is. Even though that DC uses more copper does that make it better? AC uses hydroelectric power for the energey does that make it bad because they don’t use copper? Why should DC be our electricity over AC? There are many things that you should be including in your statements.

senator (TC)

2/1/2011 05:05:09 am

In response to Bijaan who are you for? And what is your occupation? Where this is true that DC is more expensive does that make it worse? Explain your reasoning for your topics. What are some other good things about DC? Is there no more good stuff about DC that you can talk about? If so you are not making a good case for DC power.

Senator (WM)

2/1/2011 05:07:21 am

Edison’s assistant, you said that hiring miners would boost our economy. This is partly true, but if you could by the same quality cereal, one American made for 4.99, and one German made for .99, then which would you be buying? You yourself said that DC power weakens over long distances, so why would I use your power? Not only is coal expensive, but it creates a lot of pollution. AC power may be more dangerous, but with the right safety measures it could become safe. Convince me to see a reason to use your power.

Thomas Edison (AS)

2/1/2011 05:26:00 am

My assistant was in fact wrong, but has not corrected her mistake. HVDC power lines does allow DC power to travel longer distances than AC power.

Edison's Assistant (ED)

2/1/2011 06:01:25 am

I disagree with George Westinghouse because even though alternating current can cover more area, is it worth the safety risk of our people? The Brush Arc Lighting Company has had wires kill people because of the alternating current running through them. Edison’s tests of alternating current vs. direct current were indeed real and it is preposterous that we would ever be accused of rigging them so alternating current would get bad publicity.

Edison't Assistant (ED)

2/1/2011 06:02:22 am

I agree with Thomas Edison’s posting. Good outlook Thomas, direct current is the safer way to go for our future!

Edison's Assistant (ED)

2/1/2011 06:03:07 am

I agree with Bill Brown, because in our current economy, mining is a big part, and it is important that the use of copper rises to keep our economy at a steady level.

Edison's Assistant

2/1/2011 06:05:46 am

I disagree with Senator (TC) because like alternating current, direct current also uses copper.

Edison's Assistant

2/1/2011 06:09:36 am

In response to Senator (TC), the use of direct current highly supports the jobs of many coal miners. Already, our environment is being polluted for reasons that aren't even good. But, direct current electricity is for the good of mankind and yes, it is worth the risk of pollution to have good electricity in our everyday lives.

Edison's Assistant

2/1/2011 06:11:53 am

In response to George Westinghouse, I was mistaken when I stated that Direct Current weakens the longer it travels. It actually gets stronger.

Edison's Assistant

2/1/2011 06:15:59 am

Senator (WM), again I was mistaken when I said that direct current power travels over longer distances, it actually gets stronger, and when it gets to the load, more power is created. Coal is not all that bad for the pollution of the environment and it is already being used to run trains.

bill brown

2/1/2011 06:25:01 am

neel, i agree with you because cirect power will benifit me and the mine i work in.

bill brown

2/1/2011 06:28:30 am

i have to disagree with george westinghouse because direct current has been around longer. and in these days copper mining is a big part of our economy so useing direct current will help the copper mines.

bill brown

2/1/2011 06:31:02 am

edisons assistant, i agree with you because direct current is much safer and has killed many things. we should not take risks with peoples safety

Thomas Edison (AS)

2/1/2011 06:33:00 am

Might I also add that DC power has LESS of a carbon footprint on the world than AC power. DC power also allows for the use of solar panels. Therefore all the senators and unfortunately my assistant who say DC power has produces more pollution are WRONG. AC power needs much more plastic (which is harmful to the environment), metal, and wood than DC power. I might also add there are technologies and better grades of coal that are easily available that do not have many byproducts. And in today's economy (1890) coal is NOT expensive (in response to the senator WM).

bill brown

2/1/2011 06:33:08 am

thomas edison, i agree with you because direct current is cheaper

bill brown

2/1/2011 06:34:09 am

paul carrington i agree with the fact that dc is safer

bill brown

2/1/2011 06:36:13 am

i believe that dc should be the power because its cheaper. another reason is that ac harms animals and kills men. the sefety of ourselves should not be at risk:]

2/1/2011 06:49:06 am

Mr. Bill brown i would like to state that while you toss you opinions left and right, you have not once given objective facts. The reason it harms animals is because it was tested on them by Mr. Edison. Dc power is more expensive, have you thought about how many power plants DC power needs if it needs one every 3-4 miles! The sheer amount of power plants needed can cause pollution to double, thus poisoning our air for the next generations. So who is the killer now.

Thomas Edison (AS)

2/1/2011 07:01:30 am

In response to senator TC's queries I wold say that the main reason for not including some details was to get people to be interested in my point and for me to prove my point further. The incandescent lightbulb was made to work with DC power only and AC power has yet to invent a lightbulb that is equivalent to mine in quality. Moving onto the telephone company, rack systems are the only way a complex telephone company can operate its system. The rack telephone system runs on DC power exclusively and AC power has not made a rack system that is efficient. Therefore, if they switched to AC they would go bankrupt since the technology is too inefficient. This would also lead to a gradual drop in communication with people and other countries. Now the next point, I hoped would be more obvious, the AC prisoner who was killed in one shock. If we allow this to be put in our very houses, it has a higher chance of killing a person before they can be saved and therefore a less safe power system. DC power actually has the quality to save people from heart attacks by shocking the heart back into rhythm. Moving on to the next point, AC wires are actually more costly to maintain than DC wires. Since they were above ground, they are more susceptible to storms, accidents, and falling trees which would increase the chance of electrocution. DC power lines are underground decreasing the chance of any of this happening. I will also add that switching our power to AC WHICH WOULD REQUIRE AN ENORMOUS COST! There are also towns that have experienced with AC power and they have constantly complained about how it was unreliable and they couldn't even power the simplest of objects. We can't wait for other people to catch up, we have to act now! AC power is not ready to power America safely, and they haven't come up with a way to prevent many deaths, whereas DC has.

senator (TC)

2/1/2011 07:09:03 am

In response to Thomas Edison I now see your point as what you were trying to say. This makes sense to me now. I thank you for the great contributions you have given in this debate. It makes me realize more how much different AC and DC are. And how they both get power sources in different ways.

2/1/2011 07:14:41 am

In response to Paul Carrington just because DC has been around longer does that make people like it more? And maybe people think it’s a bad thing that it has been around so long and they are happy to see something new like AC. Why is DC simpler to use? Give me reasons. Is there any ways you know AC has harmed animals? I would like to know of a few because you can’t just be saying random facts without having support for those facts. How is AC harmful to people? Can you give me some examples.

Thomas Edison (AS)

2/1/2011 07:28:27 am

In response to senator WM, you have misread my comment. I did say that AC power killing a man quicker was bad. By saying that AC power had more voltage doesn't mean that its more efficient. You have to open your mind beyond the good parts of AC power. Higher voltages can lead to arcing, which creates a shortage in the wire, leaving people without power for day or even weeks. The myth that AC doesn't pollute as much as DC is not true. Think about how much coal is needed to create 1000 V (a lot right). Now think about the amount of resistance in an AC circuit (a lot). That is the reason why AC power lines have a transformer, to boost up the voltage. But transformers contain harmful materials such as PCBs and mercury which are even more harmful to the environment than the low pollution coal and inexpensive copper DC power uses. HVDC technology allows DC power lines to carry low and high voltages 100s of miles with the need for transformers or PCBs or mercury. And there are still flaws to the AC power system. As I have stated before, AC power lines are a hazard to us because of their high chance of breaking and electrocuting people. This occurred in a part of New York powered by AC power in the past 1 yr. 10 people died because a storm broke the wire as they were passing under it. The American people and I aren't going to wait for AC power to be more safe, when there is already a safe and reliable power type that has earned its reputation over the years. That is DC power.

Thomas Edison (AS)

2/1/2011 07:37:28 am

In response to senator TC, AC power killed animals quicker than a DC power electrocution, therefore, since animals are closely related to humans, this translates to AC power killing faster than a DC power line. And DC power electrocution subjects would have a chance to be saved, whereas AC power allows the person to survive only 3 minutes after being electrocuted. DC power moves in one continuous flow and is graphed as a linear function and it only deals with real numbers. AC power is graphed as a sine curve and is very hard to determine, here are some examples.

AC

In that way DC power is easier to determine and use than AC power. And also senator TC, I have been giving examples of how DC is less harmful and AC in my recent post (Tue, 01 Feb 2011 15:28:27) and further back

Thomas Edison (AS)

2/1/2011 07:42:58 am

I do agree with Bill Brown who is the voice of the copper miners of North America. AC power does, in fact, require less copper, making the price much lesser and possibly leading to a economic meltdown in copper prices. DC power does require copper and coal, so it can support the economy and the jobs of the average workers. AC power would force the copper and coal miners to lose their jobs, leading to a higher unemployment rate and the overall disappointment of the American people. DC power will allow these workers to continue to work.

thomas Edison, i strongly agree with all you have said and that direct current has been around for a longer period of time , it is safer for peoples use. It also doesnt harm nature and animals. I also agree that alternative current has a very high voltage which makes it risky for peoples to use.

paul carrington (sa)

2/1/2011 08:05:29 am

George Westinghouse, I disagree with everything you say because cheap is not always better for our community. In our community will all live and we all want to be safe in it, i now it travels faster and has higher voltage, but what we have seen is that it is harmful to people and has killed many.

Paul Carrington (sa)

Edison's Assistance, i agree because from the coal and copper direct current uses it is helping the miners to keep their jobs.

Nikola Telsa, i disagree and correct you in that alternative current is highly dangerous, direct current can also be dangerous, but alternative has more risks in using it

To my final and greatest opponent, George Westinghouse. Your very first point against DC power is very false as I have proved by saying HVDC power lines have powered towns in foreign countries over 100s of km. And DC power is able to power smaller objects by a battery, and your type of power has no such thing today (1890). DC power has been able to power motors, telephone systems, and objects that require alternative and clean electricity. AC power uses harmful materials that can and will lead to environmental disasters and deaths of human beings because of the the current's detrimental effect on the heart that eventually leads to arrhythmia which can lead to death. How in any way is this safe for the average home? The tests that provided this information were proved by completely legitimate public displays of these tests so there were absolutely no mistaken results. I say that you are the one who is faking results and trying to make DC power look bad because clearly we have an advantage. DC power has less environmentally harmful materials than AC power lines and DC power DOESN'T introduce reactance in the line, more resistance , and only deals with real power, unlike AC power. You also have to consider the amount of jobs you will be eliminating and the unemployment rate surge. Not to mention, DC power has powered more parts of New York for a longer time than AC power has and it has done so reliably. That is why the American people say DC power is good because it has been around for a long time. This technology will continue to develop and will be better than AC power in the very few ways that it isn't. Coal and pollution was one of the big topics discussed here in this debate, and it seems that coal is not near depletion and there are ways to burn coal so it actually has less of an environmental impact than an AC power plant. Copper is at the lowest price in years, and it is being transported all over the world and producing a better economy. Right now we have much more copper than this country can uses, so they are looking for ways to apply it in use. How about DC power? AC power is subject to resistance and uses tons of coal just to start its transmission. So I have established that any negative claims about the environment and DC power are false. DC power has been used in many more companies than George Westinghouse has ever been associated with. AC power falls into the skin effect and therefore has much more resistance which is hidden by nature harming transformers. And AC power requires more insulation because of this and more man hours in monitoring this. In fact, if we were to change the country's power supply to AC then the few miners still with jobs, would be experiencing frequent power outages and dangerous conditions, since mining companies don't invest in safe procedures. But with DC power they won't need to spend money on safety procedures because DC power requires little to keep it safe. AC power, I feel, is cheaper only because it is used on a smaller scale than my DC power. When a product is first introduced, usually it is less costly because more is made. Once AC power might be made the official power source of America, the prices will rise above the prices of DC power. Once DC power is made the official power source of America, the prices will be the same, since it was already powering most of America, and it will be more safe than AC power. Even boats are being run on DC power because it is more safe and reliable when powering a motor. In fact, DC power can power a motor more easily than AC power and can power many more small objects by use of a battery than AC power can DC power requires only 2000 ft of wire a generator to power it and wire can be added from there on. AC power has to have dangerous inverters places every 100 ft. So therefore I have disproved your main three points.

Let us face it. This "War of the Currents" has gone too long while we wait for the AC power magnates to try and come up with futile ways to win over DC power, but as you have seen here and in my previous posts, DC has the advantage. DC power is safe, environmentally friendly, economically friendly, labor friendly, able to power small objects as well as large ones, travel further, and is cost constant. This power type outnumbers the competitions benefits as well as defeats them. To the senators, please consider the advantages and disadvantages of each power type without bias on any past experiences. This is for the American people's lives, make the right decision for everybody. GO DC.

Edisons assiatant, just because coal powers trains does not mean it does not pollute. The fact that you said that is irrelivent and a pathetic attempt at a fact.

Senator (WM)

2/1/2011 10:57:25 am

Bill Brown, you are tossing opinions around left and right without any proof. Many of these statements are false or arguable. You said that DC is safer, correct. How is DC power safer than AC? Can it save lives? You also stated that DC is cheaper. With all the coal and copper, I would disagree entirely with that statement and over time, AC is cheaper. If you have a problem with my accusations feel free to try and back up your “facts” with actually proven TESTS AND ACTUAL FACTS.

Paul, you stated that AC has higher voltages, right? Admittedly at the time you were using it as a negative, but if I told you “ AC has higher voltages” would you think of it as negative or positive? Although DC does keep some coal and copper miners in their jobs, does it not take it’s toll on companies who, in reality, pay their salaries by using expensive DC power. I could not care less if DC has been around longer, I want the more reliable, cheap power source

In response to Thomas Edison, Thank you Thomas Edison for giving me resources that i can use to help me and to see if you are correct with your statements. I have looked over these websites and they are supported to your data. I am glad that someone finally gave more information and stated the facts. Thank you for doing this Mr. Edison.

"You also stated that DC is cheaper. With all the coal and copper, I would disagree entirely with that statement and over time, AC is cheaper." -Senator (WM) Maybe so, but if you take out DC from everything then Coal Miners and Copper miners such as myself and Bill Brown will lose their jobs, only few will be running the mines due to pumping. Therefore, the unemployment rate skyrockets up. If you know what i mean.

AC power is not under the ground because we haven’t developed that technology yet but we are working on it it will take a few more years also I do care for our community’s safety because the voltage given out of our sockets merely travel through your skin not actually harming you Thank You

In response to Nikola Tesla, you have not read my posts in depth. The HVDC system doesn't need any generators along the 100 mi span of wires, it just need one at the beginning to provide a voltage that is unwavering. This current type doesn't fall into more resistance like AC power does and you are in fact a hypocrite by saying DC power ruins the environment. AC power lines break easily and can kill many animals. Also, overhead power lines require massive amounts of wood from trees that were once home to many species of animals. AC power transformers also contain harmful toxins that are very dangerous when introduced into the water supply, which will happen. Coal is used by AC and DC power, but there are better grades of coal and some produce very little emissions.DC power can actually help the environment because it is the only type of power that can use alternative fuels (solar, heat, etc.). And the American people do not want to wait for new technologies, they want a secure, reliable, economic, efficient power system now. DC fills out most of these requires whereas AC hasn't as I have demonstrated in my previous posts.

The Niagara Falls project generates hydroelectric power with ten generators, distributing 6,800,000 horsepower which can send electricity through small towns and large cities. It has had much success, electrifying the city of New York. see Thomas THe AC is Renewable something that DC will never have

Thomas Edison

2/2/2011 09:55:45 am

Did you not read my previous post. DC power is the only one the allows for renewable energy such as solar power and wind power. Both of which are completely renewable and still need jobs to monitor them, whereas a dam would only require a lot of jobs at the beginning to make it, but then the people would be fired since they wouldn't have much of a use. Coal keeps people employed. (And by the way, the power of Niagara falls wasn't harnessed until 1895 which is not the year our debate is taking place, so your arguments are based on speculation). DC power is safe, reliable, and doesn't have a big impact on the environment like AC power does.

To everyone involved in this controversy: I, one of the three noble and gratious senators have made my decision, and hope that others can see why. I have decided that AC power is supreme.... at not being as good as DC power.I choose DC power as the winner, and let me tell you why. Mr. Edison ruled this debate with poking many holes in Westinghouse's and Tesla's argument, including completely removing some of them from play with his timeline (e.g. Niagra Falls). I may have made the wrong decision, but at this time DC power is underground, which makes it safer. It also pollutes, but with natural resources, not chemical like AC. It was almost humorous to try and watch AC's best try and compete with Edison, for he smashed their accusations and fired actual facts back at them. In fact Mr. Westinghouse either had a tragic heart attack, or gave up for i did not see him respond to many of Mr. Edison's comments, if any. I can only assume this means he gave up and he agrees with everything Mr. Edison is saying. In time, as AC progresses, a future genoration may have to look back on my and the other senator's decision and make their own, but for now DC power is the most reliable and safe power, and that is why i am choosing it. Congrats Mr. Edison You have earned it. From, Senator (AKA WADE MARSHALL)

Thank you senator (WM) I am glad you saw the side to my argument and I can assure you that as time progresses DC power will work out all of the problems you listed. Thank you for making the safe and reliable decision!

Senator (TC)

2/3/2011 01:30:39 pm

In response to everyone, I have made my decision that DC power is the winner over AC. I have chosen DC because of the responses Mr. Thomas Edison made about the way DC worked and how it is better than AC. Mr. Edison gave me lots of information on DC where as people favoring AC were not doing a great of a job as they could have been doing. They did not give me any good concrete details about how AC is better than DC and if they did they couldn’t support them with a good reason. I am very disappointed in you Mr. George Westinghouse and Nikola Tesla, because you are Tesla were the leaders of AC power and never supported your facts like DC. I also noticed that Mr. Westinghouse responded to only some of Thomas Edison’s comments. I don’t know why Mr. Westinghouse did this, but he sure didn’t do a good job when debating against Edison and DC power. In conclusion, my decision is DC power because of all of the facts that were supported with great detail. You deserve this very much Mr. Edison, you worked very hard. Congratulations to all the people who wanted DC power.

Thank you Senator (TC) for choosing DC power as the power source for America. I can assure you that you have chosen the right power source. Thank you for your decision.

I think that AC should be the power source of America. It seems to be much more efficient and stronger. Since it also keeps the same strong voltage through out that's better for large areas. It will also help large areas because it keeps the same voltage and the cost doesnt increase as fast as DC becasue of its distance. With AC a few stated how it is more dangerous because it had a bigger affect fast, but that could be good because if there was an issue it would be found immediatly and not be over looked and found later, which could happen with DC and end up being very expensive. Even though AC runs above ground, again I think that might be better so that it is easier to work with and control easier. Many of you keep stating how America needs DC to keep the copper mines running, but if we use AC then it might be better because then copper could be used more often for other things and new inventions and not be focused on electricity. I think both DC and AC have there advantages in America in different ways, but when all options are weighed it seems that AC seems better for the country now.

Johnnie Quickie, i think you have pointed out a few good points of DC, but just those few things dont convince me its better than AC. Also you say that most miners will lose their jobs, which is true, but couldnt that be a good thing? Could it be worth some losing their jobs so then they could open new careers and maybe go on to do greater things and move this country forward...?

Senator (SR)

2/9/2011 07:00:12 am

Tesla Im glad you have pointed out the safety and ways that AC can be safe, that is helpful to be aware of. It is impressive that AC powers many large areas and industries, but tell me why you think AC does and that its better AC powers those and not DC.

Senator (SR)

2/9/2011 07:18:20 am

Westinghouse, you have some very good pros. It seems as though AC has become very successful fast and you are able to keep under control. Money is something America is concerned about, so it is good you are pointing out its cheaper and more constant. My main concern is that since AC powers such large areas at once that if it goes out, that will be a huge problem. Does this concern you?

Senator (SR)

2/9/2011 07:30:55 am

Edison's Assistant you keep talking how direct current kills slower than AC and that this makes it safer... We are not looking for which kills slower or faster, i respect that you are worried about peoples safety but neither AC nor DC will be "on display" for people to play with. I think its good to know these things, but tell me more about why DC is better for people now to use everyday and the dangers of it and AC.

Senator (SR)

2/9/2011 08:04:04 am

Edison first I would like to say you have great facts and statistics it shows you were prepared for this. I think the fact it can be in a battery is important to life these days. You say that DC is like a flowing river and AC is moving back and forth, but does this mean it is less powerful? Because America is only growing and needs something strong. You also said a light is "better of with DC" why do you say this? Why not AC? You mentioned many times that AC is more dangerous because it is above ground and that it needs more work because of that. I feel as though it would be the opposite... Because if yours is underground then it takes more work to put it there, it cant go everywhere because you have to dig, you have to pay more and use more time to put it underground, and if its crushed you have to redo everything. If you ask me it would be MUCH harder to fix a problem above ground than in it... You say that most coal miners will lose their jobs (which is true) but then you say they have no where to go. That is where you slip. I do agree it would be very hard for America to do deal with at once, but a big aspect of America is that everyone has the oppurtunity to work. If they lose their job I think that most will find another and maybe even open new industries. Then you also mention the killing of animals and people... As I said before to someone this is not a toy we are debating. People will not be using it as it was tested with on animals.

Senator (SR)

2/9/2011 08:32:09 am

Carrington, Im glad you admitted DC could also be dangerous you are the first. You say its less dangerous because of lower voltage which is good in safety aspects. But, what about the fact America is large and getting larger, do you think we might end up with low power for large areas? You said they do travel far, but Im worried it might be too weak. Also you mentioned its better becasue its been around longer, why?

Senator (SR)

2/9/2011 08:42:51 am

Brown, you did not give me many facts so it is hard to discuss. But you did say AC was more dangerous and cheaper, why? It seamed other than that you just agreed with everyone.
