Re: scaling up is the answer?
@ Ishtiaq
It so happens that I live near leading boffins of ITER and they do not believe they can reach anywhere near a surplus of energy .... simply, because the conditions are so extreme that to keep the plasma going for more than mere seconds they have to replace have the bloody housing, while the plasma is still active (you and I know this is impossible).
Their prototype was due for 2014, alas, that failed miserably ... since then, they try to win time ... ITER is a money well, many governments backing, so where is the incentive ? There is none ... and the problems they face are nothing like humanity has ever faced before, they still cannot cool the chamber appropriately and they know that they are there to give fission an extension of life .... how would that make you feel ? In their situation I commit suicide ...
And the idiots on here who claim whatever, ITER cannot make their system run for more than 7 seconds, have tried for a decade ... any material they use deteriorates too quickly ... make it bigger, sure, good luck, more Watts to dissipate ...
Again, I know REAL BOFFINS from ITER, their kids go to the SAME SCHOOL AS MINE, I see them EVERY FUCKING DAY.
Fusion is a mirage that the fission idiots have cast on us to win time so they can use up all the uranium that is economically feasible to harvest ... and fission by products will be around for not centuries but millennia, but the fission scum don't get to pay the price, we pay it, like we paid for the reactors, the profits are, for the most part, already in private hands ... they need to hold on some more, by any means, doesn't matter ....
French Nuclear Industry has to come up with something like €450bn. 250 to dismantle existing reactors and 200 to build new ones, EDF and Areva are almost bankrupt, who is gonna pay that ... the French ... merci, hein ! The worst thing is, reactors need water, lots of water .... heard of climate change ? The flow in rivers in France already causes enough trouble to the existing fission reactors ...
To the downvoters, you are wrong, you do not believe me ...
