A lot has changed since this site was first published, today you have so many more options from hybrid cars, to all electric vehicles. Today almost every auto-maker in the world is pursuing hybrid and or full electric technology and consumers are the winners. Prices are falling while mileage and electric range growing.

Now for all you tinkerers out there who want to know about biodiesel or hydrogen systems for cars, let me share some advice from personal experience. First, biodiesel, or using treated, used veggie oil as fuel in a diesel engine, is a great idea, yet there are some drawbacks. You can refine used vegetable oil and use it as a fuel in diesel engines, BUT getting used vegetable oil from restaurants is not easy any more. It used to be that restaurants just disposed of their used fryer oil. However, these days restaurants are selling it to the biodiesel companies. You can refine it yourself, but, you have to refine it yourself. Buying already made biodiesel is possible, but its not cheap. For more info click this
