Geostationary Magnifying glass satellites for super solar power?

Without taking the engineering issues into account, assuming you are refracting light that was not already going to hit earth, a ton of that energy is going to be absorbed by the atmosphere before it gets to the ground.  More energy = more heat, faster climate change, worse weather events, etc.

The other thing, at the point sunlight hits the earth, it provides about 1300 watts per square meter across all wavelengths. But about half the energy won’t pass through or won’t be affected by a magnifying glass.  That means you are working with around 650 watts per square meter, with (and I’m pulling a number out of my ass here), 30% energy loss from that as it passes through the atmosphere.  So you are getting about 450 watts on the ground from every square meter of magnifying glass.

So let’s say you toss up a 10 meter (33ft) diameter lens.  Which would be hugely expensive to launch into space.   That gives you 314 square meters, or about 141 kilowatts.  The best solar panels are only about 22% efficient, so you would only be able to convert 31 kilowatts.

Congratulations.  Your 150 million dollar space magnifying glass can charge a single Tesla in 2 hours.
