The "Energy Tower" (coined by professor Dan Zaslavsky of the Technion Inst., Israel) is a proposed renewable energy source designed to take advantage of hot and arid climate systems produced by the Hadley Cell atmospheric circulation. Professor Zaslavsky has made claims that the energy tower provides "the most economically promising technology of all the technologies which are being developed to produce environmentally clean electricity using renewable sources" (2001). He can support these claims with a design that requires no solar radiation collector area and that works continuously day or night.
