Gee, let's all stop thinking for ourselves, MIT has all the answers!
Do you think all they work on at MIT becomes the Next Big Thing? If I'm working on supercapacitors, and EVs are hot, mentioning applications in EVs in a press release is a good idea if I hope to get funded next year.
I'll even add another criticism of the tech; Power densities will always be so low (theoretical limits) that the bulk of the storage in a vehicle will always be battery based. LiFePo batteries, for example, solve many of the problems with older batteries.
If you are operating at high power and have a significant amount of Xe-135 in the core and you suddenly drop power the neutron flux that is removing a significant fraction of your Xe-135 from neutron absorption is gone. But the I-135 in the core still remains and more than compensate the reduction of Xe-135 from direct fission. The result is a Xe-135 spike that will overwhelm certain types of reactors forcing a shutdown and a waiting period for the Xe-135 to decay.
Chip yields. A significant number of the 4 ways have a defect rendering one core useless. For the same reason, the Cell is speced with 8 SPEs, but the PS3 ships with 7.
"and countries that haven't made any serious effort to track satellites"
The civilians benefit from the "many eyes" factor of open collaboration. A complete program to track satellites requires many trained observers, in many locations, who can stand outside all night, every night. Also some math boffins. I wouldn't be surprised to find that even G8 nations with active space programs find the satobs.org info of value.
I'm Canadian, a musician, a member of SOCAN, and a computer geek. SOCAN sends me a check every 3 months.
Why the fuck should I have my internet bill go up $5 a month!? I'm not downloading that much, my parents aren't either. Very few people are, why should the rest of us pay? Anyway, 90% of the music I download is not covered by SOCAN in the first place, how do those artists get their money?
This is a stupid idea. Music is now, for all intents and purposes, free. I'm cool with that, and I've made a living of music for years. WHAT THE FUCK DID SOCAN EVER DO FOR ME BUT PAY FOR LOBBYISTS?
Full-length poliovirus complementary DNA (cDNA) was synthesized by assembling oligonucleotides of plus and minus strand polarity. The synthetic poliovirus cDNA was transcribed by RNA polymerase into viral RNA, which translated and replicated in a cell-free extract, resulting in the de novo synthesis of infectious poliovirus. Experiments in tissue culture using neutralizing antibodies and CD155 receptor-specific antibodies and neurovirulence tests in CD155 transgenic mice confirmed that the synthetic virus had biochemical and pathogenic characteristics of poliovirus. Our results show that it is possible to synthesize an infectious agent by in vitro chemical-biochemical means solely by following instructions from a written sequence.
Generating visually complex plant like shapes has been a mainstay of 3D modeling software and demos for a while now. These guys might have worked with botanists and expressed hundreds of attributes, but I don't see how this will translate to better tools for 3D modeling in general.
From the wikilink; "The highest temperature that aluminium could sustain over the life of the aircraft was 127 C, which limited the top speed to Mach 2.02."
Huh. If that's not a mistake (and I know metals are affected by temperatures well below melting point), it seems there's quite a bit of room for materials technology to improve on that.
Sustained Mach 6.3 would not be possible, but bursts of speed above the sustainable limit would be. I wonder how long it would take the Blackbird to get from M3 to M6 and back?
I agree with you that we could design much better planes today than back then.
Still, it's a valid point that the US has lost a lot of the experienced engineers and managers from the height of the cold war to retirement, that aeronautics is not nearly as popular a choice for students as it was, and that, in many aspects, it is more difficult to design such things today.
He's not implying anything of the sort. OP said 'Vista is slow 'cause of DRM', AC opined that it was due to backwards compatibility and 'maintaining integrity', that I took to mean 'making sure it's not hacked'.
I've been %100 *nix for 10+ years, so I have zero reason to defend MS. But even I can see that a correction of the statement 'Vi$ta is teh suxors for DRM' might be wrong. And Vista might be crap code, but I really doubt MS set out to design a resource hog.
From the hypothesis in the article, that the varying magnetic strengths result in different size cavities to capture different wavelengths, I would guess very little power would be needed. On a chip you would only need to develop whatever gauss needed in a very small area.
I believe the author of the article is confused. A ferrofluid is a suspension of very small magnetic particles. To keep the particles from clumping, they are coated with a asymmetrical molecule, one side of which will stick to the particles, and the other side repels itself and the fluid it is in, forming a one molecule thick membrane around the particle. Commonly used substances are oleic acid and kerosene. So this is not particles added to ferrofluid, it's just ferrofluid, which makes it an even cooler discovery in my book.
Ok, I just reread that bit of the article. I was confused, it seems that this is a ferrofluid composed of two differently sized particles.
We need a new word to describe the special kind of pain that occurs when you need another computer to rescue the first one, whether that's because you need the net to figure out how to fix it, or the hardware. How about "briquette"? Unfortunately, "briquetted" doesn't exactly roll of the tongue...
For most people, something like this results in a visit to the local computer store. The Eve forums are full of people who reinstalled windows.

What makes you think I didn't go to MIT?

"Piggy backing"? Your ISP probably hasn't provided much content lately, have they?

What's a Christian doing calling on "facts"?
Sorry, no link, and /. search is no help. He was talking about OpenGL and why it's worth supporting, IIRC.
Please, if the restaurant owner calls in a repairman before trying the power button, then he deserves the bill he gets.
My personal favorite /. moment was someone telling John Carmack he didn't know what he was talking about.....

How did you know it was optimal?
Huh. If that's not a mistake (and I know metals are affected by temperatures well below melting point), it seems there's quite a bit of room for materials technology to improve on that.

Japanese condoms are far superior to the condoms in the US. The difference is astonishing.

The heat in the earths core is mostly from the decay of radioactive isotopes.

Are you nuts? Thats 20% more cost upfront, 20% more power, 20% more cooling, %20 more space.
