WASHINGTON (Reuters) - The sun's abundant energy, if harvested in space, could provide a cost-effective way to meet global power needs in as little as 30 years with seed money from governments...
I link this one as an example of how *not* to do it.
Too complicated, too expensive, not necessary.
The sun, if harvested on the surface of the earth, could provide a cost-effective way to meet global power needs in substantially less than 30 years.
Concentrated solar power can do it. There is no lack of energy, even at ground level. Check out a map that shows how large an area of the Sahara desert would have to be covered with solar collector mirrors to produce all the energy needed for Europe ... and for the entire World. You will see why we shouldn't be going the satellite route for energy.
