It's tantalising to think that enough energy from the sun falls on the earth
in less than an hour to power the world's energy needs for a whole year, if
only we could find a really efficient way of capitalising on even a small
amount of that.
This $00 billion project looks interesting, but without any way of being
able to provide an 'absolute guarantee' of long-term political stability,
then in my view it's a much too risky investment.

It powers French and Swedish submarines.

Cite? Remember you are claiming it "powers" them. Where used they
are _auxilliary plants for electrical power_ not propulsion per
Looks like you are on another losing hobby horse like your air car.

Learn to use Google. Again..."It powers French and Swedish submarines".

While I am not one to defend "News" or the AirCar, but as an ex-submariner I
can't take your point here. My submarine had a heat engine-driven plant that
provided both propulsive and electrical "power". Just to confuse things, even
though the sub was normally propelled by steam turbines, we had two ways to
propel ourselves via electrical "power" from any of three different sources
(Turbo-generators, aux diesel, or battery).
I don't know anything about the European AIP submarines, but non-nuclear
submarines typically are driven only by electrical motors. There is no direct
connection between the shaft and the engine. Therefore, the electrical system
is part of the propulsion system.
