Solar Energy Cheaper than Coal

Yes. The system uses zinc batteries to store energy overnight.

does it work at night?

This thing can save our lives and help to avoid global worming.

fantastic

IAS has just announced the construction of their first solar energy plant to be constructed in Needles, California. You can read the news story by searching the stock symbol IAUS and reading the news bulliten. Good news for the company, the economy, and for the environment.

I think the real "renewable" long term energy solution is to harness all the land in suburbia. For instance a "mini" version of one of these about 8-10 feet, and a mini wind turbine also about 8-10 feet in everybody's back yard or on the back of their roofs. Each house could then produce about as much energy as it would consume. We have miles of suburbs out there. I have an half acre back yard, just sitting there that has wind and sun all day long. Just imagine halfing the money with the owner.

If solar enery panels could shade the desert earth instead of burning it then maybe they could grow something under them.

that is just great.

A google search of "elevator return energy", found that modern elevator systems in tall buildings do have special drive mechanisms that generates return energy when the elevator is going down. Thus, the complete needed technology for storing residential solar energy in a special heavy-concrete-weighted energy storage elevator is already available. The "overall energy" use for tall building elevators is very small ( just the cost of resistance and inefficiency ).

The first full scale working prototype should be up and running in the next couple of months. Each tower will produce 50 Kilowatts. Approximately 20 towers can be erected on 1 acre of land. Roughly 1 Megawatt can be produced for every acre of land!- All cheaper than coal. This is really cool!
