Researchers at Technion – Israel Institute of Technology claim they have created a conceptual power plant that could meet all of the globe’s energy needs… fifteen times over! It’s called the Energy Tower, and it uses the weight of cooled air to power generating turbines at the bottom of a tall tower. The air is cooled by water pumped to the top of the tower and released amidst air warmed by the sun. This reaction causes the newly cooled air to fall down the tunnel, allowing for the collection of power. Technically solar, certainly hybrid, and zero-pollution, if the concept translates into a working prototype it will be a major breakthrough, as it will be capable of producing power at less than present costs. It may also possibly operate to desalinate water, which is a generally expensive process as a byproduct of the power generating sequence.
