Someone told me that it is possible to directly translate heat into electric current. This seems like a fantasy to me, especially when I consider the claim that ambient room or outdoor heat could be made into electricity, and as a result the conductor would become cooler. That would mean that you could cool your house by running other appliances! Still, because electricity can be generated from light I started wondering if there might be some truth. The best I could come up with is that some sort of capacitor (or whatever it is that stores charge and then releases it) could be dissipated and would then recharge from a heat-conductor. If this effect could somehow be made regenerative, would the "electricity vacuum" of the capacitor draw charge from the heat conductor, causing it to cool whereby it would draw more heat in from the surrounding air, hot water, etc.? A bizarre and naive question I'm sure, but maybe someone has some insight. Thanks.
