Whats The Deal With Half Water Half Gas?
The new Half Water Half Gas guide is probably the best value DIY guide for converting your already existing car into a hydrogen and gasoline burning hybrid. The great thing about this guide, and what puts above the others in terms of value for money, is that it has included video as part of its instructions. This is really great for many people, because many have trouble following the normal written style of instruction. Also at only $67 this guide is really great value too.
