Interesting, if true.

I can see it now --a TV commercial with the aptly named AC-DC singing "Solar Panels, done dirt cheap..."

I tend tp be a bit doubtful about stuff like this. I wonder how you would make connections to take off power at useful levels. Also, what would the ultimate application be? Big solar farms? Every home with a solar panel roof? Problems with the latter would be sufficient power production, and the usual issues re night and dark days. Needed backups would add a lot of cost/complexity.

Calculation: 80900 TW reaching the Earth surface. Earth surface = 4*pi*Re^2 ~ 5.1*e8 km^2 flux: 1.58e-4 TW/km^2 Energy needs: 30 TW (twice today's energy needs) Efficiency: 10% Comes out to a land area of : 1.9e6 km^2. Sahara land area: 9e6 km^2. Hence, plenty of space for solar farms ![]() How to store this amount of energy is a different problem altogether . Some sort of advanced LiSPB batteries? You'd need ~ 10^11 tonnes of state of the art batteries to store Earth's yearly energy consumption. Hydrogen production? Storage?....Perhaps we'll have liquid H2 pipelines )....
