Solar Tower to be built in Australia

ASolar Tower that's being proposed is making waves in Australia. The thing, if it is built is gonna be huge, 7km wide and 1km high. It also produces energy at night and doesn't rely on the need for constant wind flow to operate.

quote:

A 1-kilometer tower can produce 200 megawatts, enough electricity to power 200,000 homes. This energy output will represent an annual savings of 830,000 tons of greenhouse CO2 gases from entering the atmosphere.

"One of these plants would produce as much electricity as a small nuclear reactor, so they are a very serious proposition," Harper said.


The government hasn't thrown money at it yet, but there's growing support.

In a big chimney, air can rise very quickly. The air reaches 65 degrees Celsius at a speed of 35 mph toward the center of the 7-kilometer collector -- essentially a big greenhouse. As it rises, it turns specially designed wind turbines and produces electricity.

When night falls, heat stored in solar cells during the day is released and continues to turn the turbines.


Weird that so many renewable energy plans involve these huge (and presumably environmentally impact-ful) facilities, like those turbine skyscrapers or the Hoover Dam.
