Very interesting, – better do it quick before oil runs out which could limit the making of the solar cells

Where find investors today for the task? Perhaps Bric’s governments or private means.

If I was a multi mijonair, I would certainly invest in this company.

Guess I need to go back to study, to back this company up in maybe < 10 years

i would work for that company and help it be number one and invest it to

The beam should be spatially coherent

lift costs per KG * KW per KG

Watts per KG are in the range of 4KW-17KW per KG.

Delta 4 = just about $7,500 per KG

1MW = $441,000 to $1,800,000

I only included the solar film weight as I don’t know what the structure weight would be..

isn’t this transmission method at most 50% effective? so 1 MW space becomes 500KW on the ground unless gains have been made..

A PowerSat beam should be spatially coherent.
