We probably will never know if this StratoSolar method works.

This is off NDA so I can go into detail.
For a few years, I was working on a way to reduce the cost of
space-based solar power to the point it could displace fossil fuels.
That's two cents or less per kWh, which is half the price of electric
power from coal, and low enough that (off

Just a quick point.
Run 80,000 hours in ten years the return is $800 per kW
per penny payment for a kWh. For power satellites, assuming 5kg/kW,
$100 per kg lifted to GEO and about 1/3 of the cost going to
transport, you get the required $1600/kW for 2 cents per kWh.
Well, that seems really low,

approach, which he named StratoSolar, was to reduce the mass from
hundreds of kg per kW to a few tens of kg by moving the solar
concentrator into the stratosphere as a large, lightweight, buoyant
structure
