According to Inventor Spot, some Israeli researchers have managed to design an “energy tower” which could become the new renewable source of energy for our planet:
The principle of it is convection. It’s 1000 yards high and 400 in diameter and is ideal for hot, dry places with a nearby source of water. The water is used to cool down the hot air at the top of the tower and the heavier cool air falls, gathering speed as it goes along, until it reaches the bottom of the tower where it powers a turbine. After going through the turbine, the cool; humid air simply goes in to the outside air.
This means that as well as these things having the potential to “supply power for the world’s current energy needs 15-20 times over”, they have the potential to cool the world down (well some of it, anyway!)
