Re: Towards Ecological Catastrophe: 2016 or Socialism: msg#00043politics.socialism.wsm.general
Another infamous maverick on this subject is the environmentalist David Bellamy, see; http://www.monbiot.com/archives/2004/08/19/correspondence-with-david- bellamy/ For what it is worth until quite recently I was myself open minded on the subject, being aware like Bellamy, that there has been some very dramatic natural changes in climate in the past. It would seem at the moment that there is an exceptionally unanimous opinion amongst scientific experts, that are not palpably tainted with financial self interest, so I can only presume that the general thesis that we have a serious human made problem is correct. I think there was a US government commissioned report recently that had to be doctored, by people with degrees in the social sciences presumably, as it was so damming. I have great faith in humanities, as opposed to the social sciences, ability to solve problems especially when unhindered by capitalism. I believe that there is a possibility of generating clean electricity from nuclear fusion, something the clever Chinese are working on now. http://www.upi.com/NewsTrack/view.php?StoryID=20060724-065917-5783r It makes you wonder, if this kind of stuff that the Chinese are attempting isn't just rubbish, what could be achieved. The "Chinese" technology seems to struggle to produce a missile that could hit a football stadium, whereas as Western technology can send one through a garage door from 1000 miles away. If the Chinese, with the technology they have, manage to produce a prototype then I think the convincing possibility for a solution will be tenable. As I understand it the idea of nuclear fusion is based on the tokamak design, developed by the later dissident scientist Sacharov in the USSR in the 60's. Probably as a result of the "primitive accumulation" of our Parecon "theorist" Tom Wetzel, that also put Spuknik, Lieka the dog and Gagarin into space. The trick is, I think, is keeping a very hot gas away from the walls of the reaction chamber to stop it melting like butter and everything else does at 20,000 degrees C. I could be talking bollocks but I seem to remember that the hot gas, the plasma, is kept away from the walls by powerful electro magnets. The plasma has a magnetic charge and is repelled by the magnets I think or something. You have to have the stuff whizzing around in a circular tube to make it hot, very hot, sort of. The problem or limit is how strong you can make your electro magnets. What limit's the strength of an electro magnet, I think, is how much electricity you can send through it without it lighting up like a light bulb and melting. Super conducting material doesn't get hot when you send electricity through it, crap for light bulbs and electric fires but great for electromagnets. Super conducting materials have been developed but they tend to only work at low temperatures ie minus 160 C. and are as yet not very practical but remain a theoretical possibility. The electromagnets would be kept separate from the reaction chamber so this is not as big a problem as it might seem. http://ec.europa.eu/research/energy/fu/fu_rt/fu_rt_mc/article_1228_en .htm Anyway, I was always crap at physics, but if this problem has a solution it will most likely be discovered in socialism, when people will no longer bother wasting their time figuring out ways of writing the software for delivering 200kg of TNT with a camera on top through someone's letterbox. --- In WSM_Forum@xxxxxxxxxxxxxxx, "robbo203" <robbo203@...> wrote: > > Re: Towards Ecological Catastrophe: 2016 > > > Thank you for this very interesting item.
