There's one thing that makes me happy about the ITER fusion project, it's a truly international endevour. After centuries of bickering of who gets the next dominant technology, its like the world's finally waking up. Waking up to realise "Cooperate or bust".

I wouldn't suppose that since all those partners bar one have demonstrated "the bomb", [the one exception having been the single recipient of the bomb], that this would have anything to do with it? No - they are definitely co-operating for the benefit of all mankind!!  Sleep well.

More chance of getting cold fusion sorted I reckon (and that was started by another guy at Southampton Uni where I am now :)

Go on then Greg - What is 'Cold Fusion' & why does it stand more chance of success than the hot stuff Mr Cox was talking about...

Cheers,  John

Just a joke.  Cold fusion was thought to be the answer to the world's energy problems - basically loading a Palladium cell with hydrogen electrochemically.  Unlikely to be any "cold fusion" going on, but still reports of "anomalous" energy production - so probably worth a on-going look.

Stars show you how to build (fairly) stable fusion reactors, plasma is very slippery stuff, dense plasma is extemely slippery stuff.  Leave fusion to the stars and flying to the birds :)

Thats the obvious line of thought if you want to be cynical, but having developed the bomb these countries have a far greater knowledge of, and respect for, the fusion process and how to harness it for other more beneficial uses -along with more cash for development in the first place. That's more likely to be the reason why they are involved. I would be more worried about terrorists playing with hydrogen bomb technology than those countries.

Interesting interpretation Greg - though surely the EU (UK/France aside) and South Korea don't have the bomb either. I read it as a map of who uses most fossil fuels!!

I was working on laser induced fusion in 1979 at Rutherford Laboratory, so I wouldn't hold your breath while waiting for a solution just yet  :laugh:

Hey Dogman.....So was I !!!! (well it might have been 1980....not sure) Small world or what! I was working on Sprite.....were you on Vulcan?

In the oil industry they say there's always enough reserves for another 40 years (this is because as the oil and gas run out, the price goes up, so more and more reserves become economically viable).

In the fusion industry they always say it's 40 years away !
(I should add that they say the same about hydrogen fuel cell cars too).

I wouldn't hold my breath waiting for fusion.

I was indeed :)  Only 2TW when I was there, I made the calorimeters to measure the plasma energy.  Dave Craddock was over on ELF as one of the designers, from the same town as me.  Did you stay at Rush Common?

I stayed at the borstal...oops I mean hostel in Abingdon. I can't remember what that was called...Rush Common is a name I remember but can't remember where that was. I made the trigger timing circuits and firing systems for Sprite....and lots of endless optics alignment, fun experiements, calibrating the Giotto sensors, etc....during a year out of Uni during my degree....best year....great fun...lots of big physics! I worked with Mick Shaw who was in charge of the Sprite setup. Great to hear from someone who was there too.

OMG - not more people who have suffered in the dreaded Rush Common House.  My God - have they all gravitated to UKAI????????????????????

Next you'll be saying you used to frequent the Fluttering Duck (Spread Eagle) - I can't take this  :canadian:

I saw the programme also, interesting if you don't know about JET, Hadron concepts associated with nuclear fusion. Personally, I'm with Greg on the 'cold fusion' concept. As an electrical engineering lecturer myself, I follow the topics closely. I did have a wry smile at the end of the prog - when each of the physisists predicted a date for achieving a sustainable fusion process.

Slipped in sideways in the programme was a little dialogue where Brian Cox proposed that we bring everyone on the planet up to half the energy expenditure of the average US person by 2050. With a manufacturer of wind turbines he then set about working out how all of this energy could be generated using non-fossil fuel means.  The programme makers obviously thought at this point that no-one would be able to follow more than a couple of two digit numbers in a row so they did a quick set of jump cuts.  However, I was able to pick out we'd need 2.5 nuclear power stations a *week* and hundreds of wind turbines a *day* to achieve the proposal.  Obviously completely unfeasible !!

Now, obviously, this sort of calculation played to the programmes's thesis that only Fusion would be the "get out of jail card".  Now, I've found that this climate area is plagued with mis-information and confusion.  Does anyone know if the calculations skimmed over in the programme have been done on something more accurate than the back of an envelope?

I'd really like to know if we are all doomed...

When were you there, Greg?

I barely existed there from 1973 - 1975, did the Assistant Scientific Officer's course at Harwell for 3 months then went to Culham labs for the remaining 2 years to work on CO2 lasers.  In the meantime did HNC day release at Oxford Polytechnic (as it then was) - which was the only life-saving part of the experience.  Got a good HNC (as I put all my time into that and not into the day job :) and went to Sussex for the first degree in Physics, Maths and Astronomy.  Downhill ever since :)
