Doyle Brewington has created what he thinks could be a solution for the Earth's energy problems. A 185-foot long tube, which is to be sunk deep enough into the ground to touch molten rock.
The tube would create electricity by turning a generator with hydrocarbons which turn into vapor when they touch hot rock, and rise up the tube. They would then be cooled and drop down to the bottom, where the process begins again.
"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."
