Electricity from Orbit: The case for R & D

I agree MrFrancisH we need to explore our geothermal, hydro, & earth solar technologies as these alone can solve the energy problem. Eg, the earths geothermal reserve is est at 12.6 x 10*24 Megajoules according to some estimates. Australia has enough 'Base Load working 24/7' geothermal energy within reach to supply the countrys energy needs for about 20,000 years or more. (This est ignores the fact that geothermal is renewable!) Inner space looks like the only affordable & practical future!

how do u get a 1 hour footage?

By owning YouTube.

I'm sorry i don't buy this at all.
1,000watts per square metre is peanuts even against the quoted 200 watts per square metre for sunlight.
The area of the collectors would need to be massive and then this energy would be needed to be converted to microwaves/lasers with associated losses.
All the rest of the lecture appears to be denigration of other sources.
100 kW is one tenth the energy of a 1,000 kVA (1 megawatt nom) transformer which is a standard industry standard in the U.K.
A weapon?

A space cable could be used to transfer electric current from the satelite solar power plants. The cable would only need to support itself. Admittedly for 22000 miles if the satelite was in geostationary orbit.
.
The experiment depends on this secret military laser he talks about.

Hi meotaku2. Perhaps I did sound a little pessimistic, the geostationary orbit would be favourite as you say. My concern would still be be the size of the arrays. The original idea some years ago was to use mirrors to reflect sunlight, but areas the size of small countries would have been needed.
Best wait and see probably?
Regards.
I see someone has given me a negative, perhaps it was because I recognised a contravention of the Weapons in Space agreement with the Russians?

Knob!
Dont try to be an intellect when, you're clearly, quite retarded.

This is not entirely true. Free electron lasers in the IR have been produced that are every bit as efficient as microwaves.  Furthermore, beaming laser energy that matches the bandgap energy of a photovoltaic system is highly efficient, a 1,000 nm IR laser beam is converted to DC electricity by silicon with over 98% efficiency. Intensities of 600 W/m2 are possible. Shorter wavelengths also mean more compact optics and smaller receivers. Conjugate optics allow large numbers of receivers
