Russell, I just knew you'd get to rebuff James' scepticism before I had a chance to! :-) Whispergen...

They have had a trial going for some time of a few hundred home installations - they asked for volunteers to try them, and I leaped at it and applied. Unfortunately I wasn't within the profile they were looking for, so that was that. It's been running a couple of years, I think. One of the annoying things is that they say that surplus electricity will be bought-back by the supplier (PowerGen), but what they don't mention is that it will be paid for at the "generated" wholesale rate, which is about 0.5p / kWh, rather than the retail price of about 10p. I think that's wrong, because the electricity I'd pump into the grid would be used by my neighbours, so there's no distribution cost involved - they'd pay me 0.5p and my neigbour would pay them 10p for it - 1900% profit for doing nothing! If they allowed net metering (I pay for what I've used less what I've supplied, kWh for kWh), it would be a lot fairer and a lot more financially viable. Especially as I'd be paying them for the gas to generate it!
