A 5-minute 40-second overview of the Energy Towers technology. Developed at the Technion-Israel Institute of Technology by Prof. Dan Zaslavsky, this is the most cost-effective technology for supplying zero-emission electricity from renewable sources. Electricity can be produced more cheaply than with virtually any other technology, including wind turbine, solar, coal, natural gas and nuclear. There also are 13 beneficial byproducts, including the ability to cheaply desalinate sea water in huge volumes.
