Sandia aiming for break-even

"The experimental results -- the degree to which the imploding liner maintained its cylindrical integrity throughout its implosion -- were consistent with results from earlier Sandia computer simulations," said lead researcher Ryan McBride."These predicted MagLIF will exceed scientific break-even."

Sandia researchers intend to test the fully integrated MagLIF concept by the close of 2013.
Temperature, density, confinement time: pick any two.

Guess it's thesame.

excellent. 2013 it is then for live fuel. see what happens.

will be a long while though before this becomes commercial, even if/when they hit Q. have long thought engineering challenges of imploding liner technology + energy take-off technology need to catch up - from production point of view also.

get the feeling whenever fusion does eventually hit the shops, it'll be rolled out in much the same way as fission - massive fuel processing/reprocessing, infrastructure and big bucks. military there too.

possibly only way it will happen - if enough traditional, big/institutional/governmental investors predict an adequate yield and a big enough/secure enough pot.

surprised the nuclear reprocessing industry aren't already investing heavily in it - they have the most to lose after all and are best positioned to take advantage. they must be feeling pretty vulnerable at present - post Fukushima/Chernobyl. must have gone tits up for them.

Nice to see MagLIF proceeding apace. This could be a big fat hairy deal once the Z-machine is upgraded to higher currents.

Meanwhile, the picture with the article just cries out for a caption contest:

The lecherous grin really does worry me.

Freak Gas Main explosion vaporizes half a residential block. Witnesses say destruction was preceeded by a really bright flash and what they thought was maniacal laughter. Lost in the blast was a local college physics student with a reportedly bright future. Authorities do not expect to find remains.

Wonder if the FoFu folks have considered preheating the gas with lasers like Sandia?

Actually, LPPX-1 (I like that better than FoFu but that's just me :) ) has already exceeded boron fusion temps without expensive and finicky lasers.

They've achieved sufficient confinement time and temps and are working on density... which lasers can't really help with in a DPF device without trying to turn it into something else.

good point.

LPP are still my personal favourite in the race.

but they've still got quite a lot of things to get right before they strike gold.

there's the whole business of funding, scaling up, etc, also.

still. nice problems to have. i hope they get there.
