Solar electricity complex to be largest tower in the world

With the preliminary approval of partners like Australia's biggest electricity retailer, the plan for the 3,280-foot high structure is moving forward, the Times of London reported recently.

The projected plant, which could supply power to 200,000 residences, is set to be built on the border of Victoria and New South Wales, and the tower would be visible at least 62 miles away.

A solar greenhouse with a 4.5 mile circumference will be spread around the base of the tower and heat air so it is about 86 degrees Fahrenheit hotter than air at the top.

The temperature difference will create an updraft of about 30 mph, which will drive a bank of 32 turbines. At night, tubes filled with water heated during the day will allow the station to continue to produce power.

The CN communications tower in Toronto, currently the world's tallest structure, is 1,809.5 feet tall.
