One of the Focusfusion.org bloggers with a bit of an inside track has now put the target for breakeven into 2011, though there's still a huge amount of "fuzz" around how fast things will progress once pB11 fusion is under way. I suppose 2010 is still possible.

Have you looked at the page? The 'wager' is whether the Focus Fusion process will generate net power before midnight ET on 31 Dec 2014. I take that that that means usable power, not simply net thermal "scientific break-even".

The only activity to date is one bid to purchase at 22¢.

There's a detailed construction and component assembly slideshow, with annotations, here: http://www.flickr.com/photos/focusfusio ... 8477/show/

Hold the mouse pointer on the info box to hold the image till you're ready for the next one. Click the "Show Info" button to toggle descriptions on and off.

About 140 pix. Lots of detail!

Thanks for pointing that one out, Brian. Nice to see a[t least one] project sharing all the interesting detail.

Pretty cool. The slideshow was a bit like a history of civilization. You start in the early frames with a plumb bob and a T-square (known to the ancient Egyptians) and by the time you get to the end you have a fusion reactor!

All strength to them.

But let's just check the reality; let's given them the benefit of the doubt and hit their upper ranges;

a) temp: In our best shot, on September 29, we calculate the average ion energy at between 160 and 220 keV

b) density: LPP physicists were able to calculate that the density of the plasma in the plasmoids is between 1 and 4X1020/cc

c) [from graph] tau: 300e-9s

Triple product reported; [22e4]x[4e26]x[3e-7] = 3e25 keVs/m^3

Lawson requirement for {>Q=1} >= 1e21 keVs/m^3

So the thing that worries me now is that with 4 orders of magnitude over the Lawson criterion, why is the thing still putting out only mJ outputs for kJ inputs? If that triple product were right, what's going wrong that it is still several oom below Q=1?


hmmmm.....

To error is human... and I'm very human.
