We probably need a complete rethink local generation and storage. Many items in a modern home run of low voltage DC with existing technology it would be possible to provide a DC ring fed by rechargeable batteries.

Oh great! Something else that needs a subsidy.

What acidification?

The oceans are basic so any co2 acts to neutralise it a fraction of a fraction of a fraction of a fraction...

also isn't carbon in seawater to plankton what co2 in the air is to trees?

This acidification I presume - http://www.oceanacidification.org.uk/

Already ocean pH has decreased by about 30% and if we continue emitting CO2 at the same rate by 2100 ocean acidity will increase by about 150%, a rate that has not been experienced for at least 400,000 years.

Who said it need a subsidy when installed it would be free.

My definition of 'free' implies a 100% subsidy of the cost from somebody else. What's yours?

Why for the price of rewiring 30 million homes and 10 million other buildings you can subsidise into existence a hell of a lot of nuclear wind

It could brought in gradually it would reduce costs of many electronic devices if you want a more efficient system it has to be planned for.

Similar to your I suspect when installed no one would be subsidising it apart from minimal maintenance it would be free no cost to anyone.

You could say the same thing about a wind turbine.

And it's a lot easier to build a few wind turbines that in it is to rewire 27 million UK households.:)

Thanks but I don't buy any of that

also coal doesn't kill anybody because no one is immortal it may shorten life expectancy a tiny bit but even that is questionable because the externalities of coal (eg a much richer nation) result in better health care which rwaults in life expectancy going up

A good point which I am sure will get me off the murder charge. I will offer to plead guilty to shortening the victim's life expectancy instead.

Wind turbines will never supply all the power we need we need a multi pronged approach and it's not the re wring that would cost it's the fitting of batteries and power sources.

I never said that they would. I was just pointing out that they were just as 'free' as your DC ring main.

I can assure you now, that knocking holes in people's walls and digging up their floorboards does indeed have a cost, and multiplied 27 million times, it might add up to a big number.

Oh great! Now I've got to find room to store some batteries and power sources, as well as endure the inconvenience of having someone rewire the house.

Seems to be a lot of fuss and bother just to keep a few coal mines open.
