1-Kilometer Tower Of Power

!splut writes: "New Scientist has a story about a plan for an interesting new alternative power design. Australian company EnviroMission has recieved approval to construct a 130-meter wide, 1-kilometer tall tower that will generate electricity from currents of air heated within a 7-kilometer greenhouse surrounding the tower's base. It is predicted to generate 670-gigawatt hours of energy per year, providing a clean source of energy for some 200,000 homes."

Re:watt-hours per year???

I use about 200 kWh a month in the summer and about 1000 kWh in the winter for a small apartment with electric heat in Montana. Thats almost 7,000 kWh per year, admittedly winter in Montana is not exactly usual, but a fridge computer, water heater, oven, and lights are all I use in the summer, for 1 person thats about 2400 kWh if i did not have electric heat or lived somewhere that is always temperate.
