What about Bio Diesel?

I have never personally tried to make bio-diesel but I know one of the farmers just down the road from us does make his own. Since I live in a small rural town I have to get permission from the city council before I could. The farmer told us that it cost him five hundred dollars to get the system. The bio-diesel costs about eighty cents a gallon. He is able to make enough for all of his own personal needs. His teenage sons actually help him to make the bio-diesel. He has several of the farmers in the area asking him to sell bio-diesel to them. He can't until he gets a special type of license. Where I live diesel is $3.89 a gallon. I don't have any idea if that website is a scam or not, sorry.

I couldn't get the site to come up. But a while back there was some people that traveled across country using bio fuel and other ways to fuel their vehicles. They were from Australia or New Zealand. They crossed the country 2 different ways. They didn't use any fossil fuels. They were given a lot of bio fuel from the cooking oil from restaurants.

What they are not telling you is the cost to produce the grain to make the bio diesel. And that it is taking away from the food supply of mankind. Yes after all you might save ten to 50 cents a gallon but you still have a carbon footprint from growing the grain. They need to look at better alternatives for energy to run machines such as solar power.
