##### How do you convert Heat into stored Energy/Electricity?
« on: May 18, 2012, 08:12:51 AM »
Hi everyone,

I am no expert in any means, so if what I am asking is silly, just tell me.

This is an example.

Lets say I have a stove top, and I turn it on full for an hour. Without putting anything on it, how can I harness the heat energy and store it, into lets say something like a battery, or anything I can use to power something.

The stove top is giving out some great heat for an hour. I am wondering if there is a way to harsness the heat energy the stove top is giving off, and storing it.

Does this make any sense?

@vironika:

There are well-proven ways of converting LARGE quantities of heat into electrical energy such as generating steam which spins a turbine attached to an electrical generator. The resulting electrical energy can be stored in a battery or capacitor.

However, smaller scale conversion would be more challenging while maintaining efficiency. There is a webpage over at ScienceDaily that discusses this. Link: http://www.sciencedaily.com/releases/2011/11/111109093555.htm
This appears to be using the "peltier-effect" (wiki: http://en.wikipedia.org/wiki/Thermoelectric_effect)

Well first don't think that something like this hasn't been thought of already.
There is fan you can sit on top of and old fashioned wood cook stove so that
it can disperse its heat into a room effectively and be driven by heat energy.
There is a person who advocates building peltier thermal modules to convert
heat from stoves or wood burning furnaces to electricity. I saw one where
you can use your camp-fire to recharge your cellphone or GPS unit. Finally
most professional energy saving cook-stoves keep an energy storage buffer
called a "shoe" hot so that a restaurant stove can be brought up to temperature
with minmum delay and maximum fuel efficiency.

If you are in a tank that is evacuated or inside a big vacuum tube you won't get hot by convection.  There is no intervening media to transmit the molecular vibrations and movement commonly referred to as heat.  You will get hot by the absorption of infrared photons though.  Somebody plugs in an infrared heater and makes it glow you'll get hot. The technology now exists to convert radiant energy into electricity but has only been designed for the near infrared frequencies and visible.  I would imagine that by the use of flurescents infrared photons could be converted to lower frequency photons and captured on larger antennae not requiring as much nanotechnology.
