CNG cars have been in use for the last 20 years by the government and other agencies. Until recently the technology has not been common public knowledge, but with rising gasoline prices more people are starting to take advantage of this technology. CNG is one resource that is an alternative fuel but there are others. LPG is another resource that we use every day. We use propane in our outdoor grills and forklifts etc. These technologies are quite simple to understand, they replace regular gasoline.

Looks like this could be the next big wave in car design. Natural Gas Vehicles or NGV for short. Great mileage and about $7 per fill up. Here are a few NGV Cars for sale now!
