I'm happy to see any money going into fusion research, but it does seem that Focus Fusion has a much better chance of delivering in the near term. If you're unfamiliar with the technology, check out the Google tech talk below.
My father worked on the ITER project for many years. This article goes some way to express the shear scale of this project, it's absolutely vast. When I was a lot younger I was taken on a tour of JET ( http://www.efda.org/jet/ ) and was overawed with the size of it. ITER is an order of magnitude bigger. The machine that follows ITER is where things get really interesting. Called DEMO, it's still in the planning phase…
My favorite memory of being in France a half year back was visiting the ITER site. Partly because we misjudged how to get there and trekked 3km up the highway from the bus stop in the middle of nowhere to get to it. It was still just a hole in the ground then - they were getting ready to put in the seismic dampeners for the base layer of the Tokamak structure. Since then I've had it liked on Facebook so I can see the…
I love that this sentence sounds like 50s pulp scifi.
Check this out, Japan is going their own way instead of this experiment According to researchers at a demonstration reactor in Japan, a fusion generator should be feasible in the 2030s and no later than the 2050s. Japan is pursuing its own research program with several operational facilities that are exploring several fusion paths. http://iopscience.iop.org/0029-5515/45/2/004 Also, they are already planning the succe…
Anyone else struck by the wildly reductionist sentiment in that statement?
Hate to be that guy, but how can a star in a bottle cost only ~105% of WhatsApp. One of them is incorrectly valued.
Though think about how popular of a communications platform that WhatsApp is, particularly in parts of Asia and Africa. It's transformed the communications industry in those areas!
That still may not account for the relatively small difference between the two, but it helps put into perspective exactly why WhatsApp was so valuable.
> will stand a hundred feet tall, and it will weigh twenty-three thousand tons—more than twice the weight of the Eiffel Tower. This is a strange sentence. (1) Notice Height of object-A; (2) Notice Weight of object-A; (3) Compare Weight of object-A to Weight of object-B where object-B is known more for its property of Height than of its Weight. The sense here (I think) is that the Eiffel tower is significantly taller…
It's crazy that the US blew over 4 Trillion and countless lives for oil in Iraq. Yet, we spend practically nothing on technology that could offer clean, safe, energy independence.

I am not sure about this one comment in the article submitted by OP. As far as I understand the temperature at the center of the earth should be as high as that of the Sun. The core is known to be the heaviest and hottest part of our planet.
