Right, that's why coal fired boilers are so much more popular than gas for home heating. we were talking about electricity generation, not home ehating. A coal fired municipal generator whose waste heat is available to heat a block of council flats for example. Done a lot in Denmark. It was also done at Battersea Power station in London. And given up, and replaced with a dedicated boiler. Makes more sense in northern and eastern Europe, where you need decent heating for half the year, and a lot more people are living in flats. |

"harry" wrote in message ... The ratio of heat output to electricity is fixed. And that is the problem. You can't make electricity without heat (loss). If you can use this loss to heat the home, well fine, if you can't,it would have to be dumped. That is obviously uneconomical. So it boils down to, in warm weather. you can't/wouldn't want to be running this device, the heat would have to be dumped somehow. If you have an industrial situation where lots of hot water is needed say, then these are the way to go. Eg old fashioned laundries. The important thing is they are sized on the heat output, not the electrical output. Any electricity surplus can be exported but not heat of course. So, if you had a well insulated house in Winter you could run this thing in the evening, watch TV, do baking, heat the house and water & export electricity by day when you might not be at home. But in Summer what do you do with the heat? Ah, you have your solar PV in Summer. Heh Heh. So, yours is being installed next week, yes ? :-) As a passive house, my house needs no form of central heating. Come the ice age, Harry, come the ice age ... d;~} Arfa |

snip Most people don't want nuclear. On what do you base that contention ? Any facts, figures ? So it will be renewables and (shale) gas probably in the future. Much more expensive so we all have to be efficient. I make everythiing energywise I need on site. Maybe *you* do, but you are in a vanishingly small minority of householders (and businesses) able to do that. As energy prices continue to soar to the point where it becomes impossible for the average Joe to keep up, I think that you will find many more people prepared to look again at just what nuclear could do to address the country's need to cheapen its energy production, and decouple it from foreign supply chains, with the potential for disaster which that sorry state of affairs holds ...

Had a long chat with UKIP energy man Roger Helmer last night. He says coal and shale. Of which there is lots. I say nuclear, because there may be lots of coal and shale but its not getting any cheaper. Still we all agreed that renewables are by and large total pants.

"Arfa Daily" wrote in message ... snip Most people don't want nuclear. On what do you base that contention ? Any facts, figures ? So it will be renewables and (shale) gas probably in the future. Much more expensive so we all have to be efficient. I make everythiing energywise I need on site. Maybe *you* do, but you are in a vanishingly small minority of householders (and businesses) able to do that. As energy prices continue to soar to the point where it becomes impossible for the average Joe to keep up, I think that you will find many more people prepared to look again at just what nuclear could do to address the country's need to cheapen its energy production, and decouple it from foreign supply chains, with the potential for disaster which that sorry state of affairs holds ... Arfa What makes you think nuclear will be cheap? http://en.wikipedia.org/wiki/Nuclear_power#Economics If you go the way I have gone, all this becomes irrelevant. You need to take advantage of subsidies NOW and become energy independant. Otherwise in the future you may well suffer *fuel poverty". Not sit on your arse and whine like the old dope TurNiP. I expect he's a socialist, expects a nanny state gov. to spend taxpayers money. High energy prices in the future are inevitable. So you need to GOYA and do something about it. Solar energy prices will seem cheap in five or six years from now. |

Jeez. The remaining heat is not wasted, it goes to heat your home/hot water. The problem arises when you have no use for that heat, ie Summer. Surely if people still think of it as a central heating boiler, rather than as a generator, or cash machine, they won't switch it on when they don't want heat? |

Which mountains and valleys did you have in mind, harry boy, for hydro power? There are lots of potential sites for micro hydro. Many where water mills stood in the past. Many are now being utilised. **** all are in fact. And there would be NONE if those parasites and thieves like you weren't being paid terminally stupid FIT tariffs. We need as much diversity as possible. Nope. What we actually need is lots of nukes instead. The result the frogs got proves that. |

Are there unlimited oil reserves then? What's wrong with say tidal electricity schemes? None of these renewables can supply more than 5% or so of our requirements. Unless you put 3 turbines of every sq mile of the UK, including cities. Or dedicate the whole of Wales to biofuel crops. Or damn up some of the larger the Welsh valleys to act as pumped storage. Good luck with any of these. Tidal power is the next big one. If it's hyped enough to make it actually look practical, what it will be is the next big one for the eco-bollox power production companies to jump on. People are beginning to suspect that the windmills that these companies are wrecking the countryside and coastline with now, might not actually be delivering this mythical abundant renewable and 'free' energy. So now would be the time for them to switch to a different one, and start collecting a bunch more government handouts for 'developing' and installing them. Build the nukes, and be done with it ...

Tch, You are a dope. *Getting electricity for the price of gas. Yeah - at a very inefficient rate Tch. You still don't get it? The remaining heat warms your house. Almost nothing is lost and you get cheaper electricity. IIRC this company is looking for investment(*), they install the complex boiler for free and keep the FiTs. This complex boiler becomes yours after five years and thus presumably the maintenance of it. There is likely to be only one company capable of maintaining it, so you can imagine what that price will be. Five years? They don't have much faith in the life of their product do they, bear in mind the FiT is 20/25 years. And what is the efficiency gas - electricity, 10% so 1kWhr of electric consumes 10kWhr of gas at what 5p/kWhr at current prices so is 50p/kWhr and you don't even get the 10p/kWhr FiT... Having looked at how the thing works it doesn't look to me like it's using "waste" heat but tapping of a proportion as an when the boiler is running. I'd like to see the gas consumption figures compared against an A rated boiler running in condensing mode with both producing the same amount of heat for heating/HW, over a range of outputs as most boiler modulate these days. (*) Note looking for investment not particularly trying to promote anything "green", this is purely to make *them* money. -- Cheers Dave. |

Are there unlimited oil reserves then? There may well be. Ther are very large uranium/thorium/deuterium reserves. I think we should leave a bit on the plate for coming generations, rather than greedily gobbing it all ourselves. What's wrong with say tidal electricity schemes? same as is wrong with solar PV and wind. They are expensive ways to achieve sod all carbon fuel savings. I was thinking about the Severn barrage scheme that's been proposed multiple times. Building it would stimulate the UK economy. It would provide around 5% of all UK electricity needs for the next 100 years, by which time it would be nicely silted up, thus providing 100's of square miles of new agricultural land. The main thing that seems to be holding it up is that it would disturb some wild-life. It doesn't need to be justified economically purely on the value of electricity generated. The point is to stimulate the economy and reduce unemployment, so some of the money spent will reduce social security payments, etc. |
