Making ethanol, and converting engines to run on it
There has been a high interest in the last few years in making your own fuel. This can range from converting diesels to run on used fryer oil, to making ethanol, and converting gasoline engines to run on it. We have also been converting gas engines to run on propane and methane. For information on how you can make and use your own fuels, see http://www.green-trust.org/ebooks/.
Professionally, I'm an IT Engineer (Executive Level) and Electronics Tech. Philosophically, I'm a Green Conservative, and probably would have been a hippie in the 60's if I had been old enough. I live off grid, with Solar (PV), Wind, and veggie oil fueled diesel generator power, and have been teaching and living sustainable technology for over 10 years.
