Diamond Bullet Fired at 1000 KM/S Can Produce Nuclear Fusion, Chinese Researchers Say

Posted July 07, 2010 1:17 PM

From Popular Science - New Technology, Science News, The Future Now:

Diamond Fusion A team of Chinese researchers proposes firing tiny diamond bullets into a chunk of crystal methane to produce nuclear fusion. A millimeter-sized diamond bullet fired from a linear accelerator can produce nuclear fusion when it collides with a chunk of solid methane, according to a study by Chinese researchers.

Flinging things into other things really, really fast can make a very bitty fusion reaction. And if this too is sucessful then that's one more bit of data to add to the pile. But it's highly unlikely to be "the" fusion solution we've been hoping for.

Me? I'm hoping it produces some really good corned beef and a 2:1 scale living duplicate of Winston Churchill. I mean...as long as we're hoping.

Who #$#$#$ published that results, it is a state secret. I am going to jail all of you now, b#$#$# trouble makers engineers and scientist

Hang on: am I missing something here:-

________________________SNIP________________________________

VII. CONCLUSION AND DISCUSSION
Hypervelocity macroscopic particle impact can open a
door to a unexplored field of high energy density physics,
new states of matter may occur, new understandings
about HED matter may come out of direct observation,
and impact ignited thermal nuclear propagating burn
may come true.
We discussed the physics of Diamond-DT methane im-
pact fusion (DMIF) scheme. Simulation shows the igni-
tion energy is about 1 MJ, which is of the same order of
other ICF's. This is only one fiftieth of previously be-
lieved value in 1980. Take the example of the ignition
case in Section VI, the length of the accelerator is about
75 kilometer, if the accelerator field strength is 30 MV/m
as in ILC. There is still quite some room for improvement,
because the field strength the bullet can tolerate is still
a few hundred times away (ยป 10 GV/m).
With all the inborn advantages, DMIF can be a
promising inertial fusion energy candidate.

Guess I'm missing something...

When I calculate the kinetic energy I get a lot less than 4 PW.

(1/2)(.0035 Kg)(1x106 m/sec)2 = 1.75 Megawats, not 4 Petawatts

Something doesn't seem quite right.
