Solar Panels
Solar panels?
Following the anvil on a cable in space question. why not attach a couple of wires to a load of solar panels floating in orbit? solving all our energy problem needs. or cover the sahara with solar panels. aparts from a few scorpions and nomads who’s it gonna hurt?
1. Solar panels are extremely inefficient, on the order of only 1-2% efficient.
2. The cost is so high, it is not worth it. The panels cost far more than any “free” Electricity.
3. The cable from space would be too heavy, and air resistance would bring the solar panels down.
Instead, use mirrors to concentrate the sunlight, and use it to drive a steam turbine. The efficiency can easily be over 90% if done properly, yielding about 1,000 watts per square meter at high noon at the equator. A mere 20 square kilometers would provide about 360 megawatts. and 2/3 of the energy can be stored for evenings and cloudy days.
