I think you are bang on re CSP, and I have been following with interest what Sterling Energy Systems have been doing with this in the US.
As for the electric motor, I remember visiting a company called Frazer Nash which had been doing just this for and put four motors, - one on each wheel - to drive golf buggies which wiped the floor with the competition.
(I think) they later produced some people-mover vehicles for the Sydney Olympics and then ran into some murky corporate goings on, unfortunately.
The key was their expertise in traction control hardware and software. They had some electric Go Karts which were absolutely awesome.... "Any economic unit can emit money. The serious problem is to get it accepted" Hyman Minsky
Come on, let's just get this done. What happened to the Energise Europe proposal? It can't be that complicated:
--Europe's current usage of energy = X (If necessary--An individual country's usage is X/Y)
--Current possible production with Solar = S1 --Possible future production (stage 2 tech in 10 years) = S2
etc...
All our other discussions are, I think, secondary to this one. If we build more coal/gas (nuclear I would study only after solar and geo-thermal limits have been reached...
It all just kinda went...well...where did it go?
Ach, I'm rambling! Good diary, emilmoller. Thanks again. Don't fight forces, use them R. Buckminster Fuller.
