As gas prices climb upward, natural gas is abundant and cheap& likely to remain that way. However, because of technological and legal hurdles involved in converting a car to run on natural gas, it can cost thousands of dollars up front.
Frito-Lay is running more than 200 natural gas trucks and installing stations. A waste hauler in Connecticut has already pumped a million gallons of the stuff. At half the price of diesel (and with greatly reduced emissions), #CNG and #LNG are taking over the trucking business.
