The guys over at otherpower.com
have done an excellent job documenting their advanced projects in home
power generation with a series of easy to understand images.
The picture to the right is a steam powered engine they use as a back
up battery charger if their solar and wind systems fail.
It must be a good feeling to know you can make your own electricity
with fire. This set up cost them less than 500 hundred dollars thanks
to being in the right place at the right time.
I'm sure building something this big and heavy from scratch would require some
advanced skills and expensive tools and materials. I wonder if it's
possible to design a smaller version that would still be strong enough
to turn a small generator?
