'Termite guts can save the planet,' says Nobel laureate

Public release date: 13-Apr-2005

The way termite guts process food could teach scientists how to produce pollution-free energy and help solve the world's imminent energy crisis. Speaking at the Institute of Physics conference Physics 2005 in Warwick today, Nobel laureate Steven Chu urged scientists to turn their attention to finding an environmentally friendly form of fuel. In an impassioned plea to some of the world's brightest minds, he explained how he's leading by example, and encouraged others to join the effort which "may already be too late."

Chu, who shared the Nobel Prize for Physics in 1997, has begun studying termite guts – one place in nature where a key hurdle for carbon-neutral energy supply has already been solved. Termite guts take indigestible cellulose, which makes up the bulk of all plant material grown on earth, and convert it to ethanol, which even today is a versatile and popular fuel.
