Could giant towers in the desert produce massive quantities of electricity at very little cost and with no pollution whatsoever?  Well the idea may sound far-fetched, but not for one development team in Israel which is beginning construction of just such a pilot project in the Arava Desert.  According to the Earth Times, salt water will be piped to the top of a 3,000 foot tower, and sprayed into the hot air above it.  As the water evaporates, it cools the air which quickly speeds down the tower and becomes a powerful wind force that could spin turbines and generate electricity.  Since the technology might also be used to desalinate water at half the cost of current methods, here’s hoping these towers gain lots of altitude in solving some lofty development concerns.
