That would have been the french!
They sold them nuclear technology tanks and telephone exchanges at the time
we were trying to sell them System X exchanges.
They would only buy the System X exchanges if the UK government sold them
Harriers but they didn't.
The french again!

I can believe that 11w/sq metre for the US, given clouds, time of day
and the tilt from being 45 degrees or so up from the equator.
NASA are of course quoting cell *output*...

As to the last question, we could ask for a reply from any
Roman galley operators or Vikings perhaps?
But you know, we have plenty of hardened criminals using
exercise equipment in our prisons, (so they can get a "girlfiend"
and not be someone else's).
Then there is immigrant labor, maybe they would peddle a
stationary bike for $.03 a kw?
Oops, that might be taken as Politically Incorrect.
I, of course, meant no disrespect to any Vikings that
may have read my post.

I actually half assed presented that idea to an investment group one time
-- It wouldn't actually generate that much power, but the marketing for
green minded folk is where you'd make the money .. making people feel
good about running on a tread mill like they are combating global warming
or nonsense like that.
Also i'd install my (pat. pending) piss turbines in all the urinals

The shear scale is the bugbear.
It's Christmas so lets indulge ourselves and use real units.
1 horsepower is 746 watts. Lets anticipate some losses and call it a
Kilowatt. 1 horsepower is also 550 foot pounds per second. So 1
kilowatt for 1 hour could lift 550 pounds a height of 3,600 feet.
that's for about 12p's worth of electricity. Mix and match how you
like (Eg. 5,500 lb's for 360 feet) it doesn't get any more workable.
It would be expensive and wouldn't be safe. It would store about the
same energy as a single 12 v 80 ah leisure battery.
This is for your "Hut-Sut" in Sweden I take it ?
Better maybe to cut timber for heating and cobble together a water,
steam, or alcohol (FWIR the Swedes have already cracked the technology
for that ! ) etc. powered generator to give a hundred or so watts of
The Swedes have been living there quite a long time you know, and it's
difficult to be a "child prodigy" in these matters. What do they do ?
Well good luck with it anyway.
