Another article on this here.
I don't see why this method can't be adapted to deposit graphene directly onto integrated circuits, which ought to be a big fat hairy deal.

Higher Gain MTF By Monkeying with Pellet Composition
Anybody know about this?

Sure sounds like a lot simpler geometry, and one that could be tested relatively easily.

The other thing they're doing is leveraging a lot of other proven or semi-proven components. Scaled Composites is doing the aircraft (presumably leveraging some of the White Knight tech), they're using off-the-shelf turbofans, and they're buying SpaceX motors, if not boosters. Frankly, the thing tha...

This Ought to Be Useful for Plasma Diagnostics
http://www.technologyreview.com/computing/39329/?p1=A2
I don't know about the limitations of streak cameras in high-energy environments, but this looks like an interesting diagnostic tool for a whole bunch of things, including plasmas.

I do not know. It looks cool, but I remember reading cost analysis by SpaceX stating that these combined "air breathing winged first stage then rocket" are not really very effective. Their argument seems to be that airstrip ops are a lot faster and cheaper to turn around than launch pad ops. They'r...

Just read that the story about diesel back-ups getting innundated was cover story to give some hope that cooling circuits could be got back on line ... yes the back-ups were innundated but that wasn't the reason cooling circuits weren't ever coming back online. The real reason was that when the tsu...

Now they've had an LOC at reactor unit 2 as well: http://www.world-nuclear-news.org/RS_Loss_of_coolant_at_Fukushima_Daiichi_2_1403113.html Serious damage to the reactor core of Fukushima Daiichi 2 seems likely after coolant was apparently lost for a period.

Interesting thread. However, it would be nice for somebody to disentangle the interesting science from the aspects that make for good policy. It seems like there has been a recent acceleration in the production of interesting results in magnetically confined plasmas, and it's certainly possible that...

Re: NASA Planning Mission to Visit the Sun
Since NASA has never sent any vehicle this close to Earth's Sun, the craft will have to be outfitted with a special shield designed to withstand radiation and temperatures exceeding 2550 degrees Fahrenheit. A spokesman for NASA said scientists will depend on simulations to guarantee that the probe ...

Ah, got it. I was thinking that the B-field was a sheath, but it's not. It's diamagnetically rejected from the center of the machine, but the mostly transverse B-field gets stronger and stronger the closer it gets to the magrid coils. So the real question is what the condition is to avoid the fusion...

I don't have a link either. But my memory is tolerably good: alphas . Think about it: Polywell needs about 100,000 passes of electrons (probably a similar number for ions) to make the device deliver net energy. So from that alone the odds that "1,000" passes is about fuel is rather low. This doesn'...

Shouldn't fusion products have enough energy that, even if they hit the B-field perfectly perpendicularly, that they have an effectively infinite gyroradius and punch right through? And, if they hit a cusp, won't the particle simply go through the cusp and break free as the field lines bend back beh...
