Others are also catching on to the idea of using non-fod plants for biofuel. One oil tycoon, Lord Ronald Oxburgh, has suggested using jatropha, a plant that apparently has as tough an upper lip as its regal proponent. Jatropha, too, grows on degraded land where no other plants will think of putting down their roots. His company, D1 Oil, has already started collecting jatropha oil, and others are hot on his heels. Just last spring a Japanese company agreed to invest $800 million to grow jatropha in Cambodia. The US is in on the trend as well, with companies like GM, DuPont, Range Fuels, and BlueFire Ethanol all opening up or investing in non-food-based fuel plants this year.
In the race for cellulosic ethanol (non-food biofuel), participants are still warming up.
