Home wind turbines dealt a blow

Very good idea.

Should have used battersea power station..

Definite economies of scale. BTW submarinse DO have very powerful motors. Myabe not in te GW class but several tens of MW..

I would support that. Or close by.

However fuel efficiency is not an issue with nuclear power. The fuel is probably less than 1% of the cost of generation.

Much easier to build - say - a nice set of greenhouses around the outflow, and produce out of season mangoes ;-)

Given that nobody has tried, that assertion is obviously incorrect.

They may think that it would take a long time to get planning permission, but that is different.

There is an easy way to deal with this. The company can accept responsibility for the clean up, of at least the site if not the spent fuel. They could for example deposit a bond.

If you'd be happy paying higher electricity prices because the power stations are build on expensive land.

Great idea.

Pipes over 2m high with about 50mm of insulation on them snaking around the streets by the side of the road. The system is turned on on the

They do already. But the problem is, to what standards must they clean up?

Right now its an open ended risk that no one will take.

If some bunny hugging government comes in and insists of making it less radioactive than distilled water, they may be faced with total ruin.

The point is that the rules applied to nuclear energy are a million times more stringent than those applied to conventional power. And they are not cast in concrete either: at any future date the companies MAY be required to change their standards massively.

Or be nationalised like some third world country.

You cannot enter a commercial arena with completely unqualified risks at the whim of a government, in competition with other players who are doing massive proven damage to the environment, and who pay *nothing* for the effects they make.

Well you could build residential and office blocks on them with free lighting and heating. That should cover the land cost.

And a train station next door with a sunstation to feed the power lines..

Sounds like some council flats I stayed in in Denmark. Had some kind of waste burning boiler..

It was done in London: waste heat from the Battersea power station was piped under the river to heat the Pimlico estate

Not a vote winner, I suspect. But it could make sense to put acres of polytunnels next to a power station and grow tomatoes etc all year round with free heat - better than flying the stuff thousands of miles.

I thought that was once done at a power station somewhere.

I'm pretty certain a distillery in Scotland used waste heat for a greenhouse project, toymorey(sp??)

I think one of the schemes by that chap that wrote in "New Scientist" was to rotate trays of tomatoes between decks of a large redundant supertanker around the equator and head for home as they became ripe.

District heating is done better in a number of places. Iceland is perhaps the best known.

There are a number of schemes.

The scandinavans manage to pump hot water for great distances without excessive loss.

The (specific)? heat of water is pretty good, and so is modern insulation.

Capital cost is pretty high, but it should be cost effective over medium distances I would think.

No, no, you got it wrong It's not a dollar. (Hell, that would be

Have they made any? Yes, last week.

Do they work? Hard to say.

Have they measured how they perform ? Erm pass on that it's not summer in Calfornia ...

God help them in Switzerland it's always been pissing down when I've been there.

Greenmythology only works in "magic numbers". IE CFL's last 25 years.

Then you put your money where your mouth is.

If you have any.

CFL's are the answer (not) . They last 25 years (not).

Unlike wind turbines, they only last 19.

Whereas the CEGB Magnox stations seemed to last about 40.

The life of any lamp is stated in hours used.

A CFL (depending on type) should have 5-10 times the life of a GLS lamp. If you used it an hour a day a 25 year life is possible.

They have big open air baths there but only because the heat comes straight out of the ground

And you have to have a gob stopper in your mouth in order to speak the language.....
