Call The EPA and Jimmy Carter on the Batphone. It's a free call.

Hmmm...Free sources of energy? The air or the sun. The wind-generators exploit the speed of the wind to produce electric energy with the rotation of their coils. Or we can get free energy from the solar radiation with photovoltaics. > How it works is your burn wood in a stove, and > boil water using the heat generated from the wood fire.

It was easy to determine how many BTUs you would get from cordwood, how much you would need to boil a gallon of water, and the efficiencies of ovens and your steam turbine. However, I was at a loss to determine how much water you would require to power the turbine, and, more importantly, the temperature of the water. My advice is, unf., rather simple: 1)Get as efficient a stove as possible. Most stoves have a 10-30% efficiency. An excellent high combustion stove can net you a 70% efficiency. 2)Burn as dry a wood as possible. Typical firewood can cut your available BTUs/lb. from 8,600 to 3,400. 3)Boil as pure a water as possible. Trace salts are going to destroy anything metal in your apparatus. 4)A backpressure steam turbine is the most efficient way of generating electricity ever, with 75%-90% efficiency. 5)Get a good, solid background in engineering before deciding to scald the skin off of your body by fooling around with high temperature steam turbines. Or better yet, acquire minions. If you do manage to get a ready available source of cheap dry wood, this method is actually a very efficient method of powering a small arcology. I wouldn't use it to power an individual home. Too much air pollution. In _How to Convert Wood into Charcoal & Electricity_ by Richard H. Buxton, Buxton converts the carbon monoxide and hydrogen given off from wood combustion into fuel and then uses the fuel to run a generator, which seems safer for a novice.

Most physicists are pretty sure a "free energy" machine can't work because it violates the first law of thermodynamics. However, that hasn't stopped the eternal procession of perpetual motion machine inventors. http://www.lhup.edu/~dsimanek/museum/unwork.htm But if you don't choose to let a little detail like the fact that your machine doesn't actually work get in your way, you could be a successful free energy poineer in your own right.
