And then some.
The numbers I’m seeing thrown around (I don’t know how verifiable they are) state 92% solar efficiency, 50 kW per tower, 20 towers per acre. From the article: “Although the sun does not always shine on the solar plant, the company believes that using a heat storage mechanism, they can deliver power around the clock at an estimated production cost of 5 to 10 cents per kilowatt hour.”
That “believes” part might represent a big catch. If not, however… well, maintenance and replacement costs may be significant and prevent wide deployment. The future is not necessarily today.
But it’s soon.
