I thought it might be a good thing to have a topic devoted to this important subject.

You can get nice luminesance from the inside of an old X-Ray machine, Unfortunately you tend to attract the attention of men dressed in orange chemical suits wearing breathing apperatus and driving bulldozers.......

We've kept low-energy bulbs in various house lights were it doesn't matter that they are slow to reach full light output or that they give out a rather harsh light. But where we need quick lighting I'm keeping the old bulbs for now. The blue light from LEDs is OK for some purposes but don't try reading by it! (poor contrast of black print on bluish paper.)

Wendy, do you know if solar heating panels are available in a variety of sizes? They always look about the same dimensions to me when I see them on roofs. If I had them, the ideal would be 2 foot high but very wide so that I could put them over the hanging tiles below my dormer windows.

Pluggy mentioned radio interference from LEDs. Watch out too for TV interference if you put aluminium reflecting insulation on the sides of your loft or under the roof tiles (and have the aerial in your loft).

Luminescence reminds me of a bloke called Harry White who was a sign-writer in Stockport pre WW2.  He had a lucrative sideline in the early days of the war going round painting people's house numbers and keyholes with liminous paint so they could be seen in the blackout.  General Gas Appliances had a contract at the same time for enamelling 'luminous buttons'.  They were about two inches across and the idea was that it would stop you bumping into people in the dark.  In both cases I suspect that the radio-activity would be totally illegal today.

Sorry Tizer I can't help you with that one. We got our DIY kit from the solarshop website  They have a lot of info on the website, and will advise you on what you would need .

I listened to Professor Lovelock on climate change the other night.  Frightening stuff, it will be the Staney's View article next week, too late for the press this week.

I didn't know Lovelock was on - if it was radio I might be able to find a podcast. Radio 4 perhaps? Did you see the three climate change programmes by geologist Ian Stewart a few weeks ago on BBC2? They were very well balanced, but worrying conclusions!

He was on BBC4 maths programme about 20:00 on Tuesday night.  Programme was on chaos theory and quite fascinating. Seek it out. His contribution was on chaos theory and climatic change.  Basically he says we are stuffed.

Our preparations for climate change are going to be set back by the credit crunch. There might be a slowing down in CO2 production due to lower economic activity but that is offset by companies abandoning plans for projects on alternative and sustainable energy sources.

And there are big obstacles to progress on other energy sources. An article in The Times points out that development of electric cars is held up because of a serious shortage of lithium for the batteries. Experts warn there is nowhere near enough lithium for the requirements. Too much has already been mined out for use in laptops, Ipods, Blackberries and mobile phones (the idea of banning new and recalling old laptops, Ipods, Blackberries and mobile phonesappeals to me somehow!).

Wind turbines are held up due to a shortage of gearboxes and bearings which are made by a small number of companies and there is a big shortage.

We are supposed to need another 237 nuclear power stations but we can only make about four reactors a year. There are only a few companies able to handle the 600-tonne castings for the reactors and one of these companies, in Japan, makes 80% of them. There is a long waiting list and Japanese power companies are getting favourable treatment.

The credit crunch has made politicians take their eye off the ball.It's all very well solving the economic difficulties but we will end up in something much worse unless some political heads get banged together soon.

Dead right Tiz....  Has anyone heard they are cutting back on bum IT contracts and nuclear deterrents? Can we couple the Tridents up to the grid? One hour power cut last night in Barlick........ Where does one buy paraffin for the Tilley lamps now.

Plenty of sources on the net, just punch Tlley in on Google. I have three fully refurbished Lamps and spare mantles. What I need is paraffin, I've asked round but up to now haven't found a source. If anyone knows of one please let me know. I am convinced that power cuts are coming sonner than we think and I want to be ready.

Nicholas Stern (Lord Stern) was interviewed this morning on BBC radio's Today programme by guest editor Jarvis Cocker. After the interview, Today presenter Euan Davies said he had tried himself many times to get Stern to give his views on President Bush. But it was Cocker who finally managed it...

Stern hope over US climate deal

Economist Lord Stern has said he is optimistic that a global deal to reduce carbon dioxide emissions will be struck under the US presidency of Barak Obama. Lord Stern, who was behind the first detailed economic assessment of the impact of climate change, said US and Chinese agreement to a cut was crucial. President George W Bush's climate views were "prehistoric" and had been seen as an obstacle, Lord Stern told the BBC.

But many now believed the new president could take a lead, he said. "He's night and day on this issue relative to his prehistoric predecessor George Bush," Lord Stern told the BBC's Today programme's guest editor Jarvis Cocker. "That is a very big change and, while people saw the United States as a obstacle, now people are saying well perhaps the United States could really lead on this. And it is going to have to - because the two big ones on this are the United States and China."

Lord Stern said that, as well as hoping for action from the new US leadership, he was also encouraged by the the much deeper global understanding of climate change and its impact. Many countries had made a clear commitment to reducing greenhouse gases, he said, which showed things were moving in the right direction. Technological advances would also help, he argued. "It's a big challenge but we have got a chance".

But he said he did not underestimate the scale of the task involved in creating a global agreement to combat climate change to take effect when the current Kyoto Protocol expires in 2012. "Let's not forget just how big a challenge it is. We're trying to put together as a world the biggest international collaboration the world has seen and it requires that," he said. "It is unavoidable that we do that if we are to be serious about this problem. So, it's a big challenge, but we have got a chance."

Lord Stern also said he believed the world could learn a number of lessons from the global economic crisis when dealing with climate change. "The first one is that the longer you let risks fester, the bigger the impact and the bigger the crash and consequences. If we emit greenhouse gases the concentrations in the atmosphere build up and it gets more and more difficult to act the later you leave it. The second lesson is that we're really going to have to collaborate on this one." Slowing down the work to tackle climate change during the current economic crisis would be a mistake, he added.

"It is fair to say the kinds of monies you would have to spend each year on dealing with climate change, in the sense of cutting back on emissions... at the moment looks quite small relative to the sums that we're having to put in to shore up the banking system."

I haven't read through this entire thread but it seems that a lot of people think that global warming has been caused by humans.

I'm far from convinced that this is the case and I'm equally far from convinced that anything we do is going to cause the slightest diference.

Having said that, I am very much in favour of recycling and reducing the extent to which the earth's resources are being plundered. I just don't believe that it will have any effect on global warming.

I suppose it depends on whether you believe in the sentiments expressed in the film 'An Inconvenient Truth' or whether you believe in the sentiments expressed in the film 'The Global Warming Confidence Trick'. I have seen both and I believe in the latter,

I don'r 'believe' in either in the sense that they lead me to an unshakeable position. I'm a historian and have seen plenty of evidence of climate change through natural causes. however, what I do strongly support is any move to cut back on the poison we pump into the atmosphere, the evidence is quite clear, it damages the environment. One of the big problems is that the two issues of pollution and climate change have been mixed together to the point of confusion. This is the whole point of the Gaia Theory and seems to me to be perfectly logical and supported by the evidence.
