Wind energy may not necessarily be in step with the growing solar powered solutions to deliver the power requirements needed today but this monstrous power generator may yet somehow pull it abreast. Set to be put up over at the south western corner of Arizona is the Downdraft Energy Tower which will make use of evaporating cooling to deliver electricity for medium to large sized cities.
The said energy tower has actually been around for some time and until now, no one really dared reveal it in real life. The whole process seems simple; cool air is denser, sinking down, while hot air rises. At the top of the tower is a fine mist of water sprayed across the air in order to cool it. This results in sinking down the tower at a rapid pace.
At the bottom is an escape route for the air to pass through and thus making their way through hundreds of wind turbines simultaneously to generate huge amounts of electrical power.
