This guy publishes a very interesting book on a home built "dynamo" for generating your own electricity. The work is within the capacity of anyone with basic knowledge of hand tools. How about combining this with a home-built recumbent bicyle rig to drive it? See my transportation page for info on this.

We've all heard those stories about the 300mpg carburetor, etc., that was bought out by the oil companies, car manufacturers, etc. and suppressed. This web site lists no less than 7 different "suppressed" carburetor designs (some of which are available throught the mail still!!) Not to mention various alternative fuels, fuel additives and other "alternative" energy devices and engines. Check it out, it's an eye opener!
