If you are thinking about alternative fuels there is a thing that comes in your mind very fast. In most cases hydrogen fuel cells. But what is that and where can you get more infomation about this topic. A lot of sites are providing water for gas books. These are quite good sites but this is only one topic about alternative fuels. There is so much more like biodiesel. I think the best way to choose alternative fuels is to read some really good advices about alternative fuels. Water for gas may be a quite good way, but there a lot of others that may fit better.
