Electricity From the Earth's Core?

Power Tube concept seeks to use low temperature geothermal heat to generate pollution-free electricity, but other experts critical of inventor's claims.

> A radical new method of producing electricity from the Earth's inner heat has been devised by a power plant designer from Texas.

Doyle Brewington of ESOR Consulting Engineers in Houston has designed a long, self-contained turbine shaft called a Power Tube that could tap subterranean heat without relying on geysers and steam vents.

"I spent 25 years building power plants and I saw the damage they were causing," Brewington said. "The noxious gas being emitted by a lot of these steam turbines were causing a lot of acid rain around the world."
