Nickel-62 has the highest binding energy of any known isotope of any known element. You cannot extract any energy from any nuclear reaction involving that isotope, fission or fusion.
A proton has the lowest binding energy, though. If you do the math you'll find that Ni+p weighs more than the resulting Cu, so you do get energy.
Mind you, the whole thing is nonsense. There's no way they are getting Ni to fuse with a proton.
If you're referring to Kasparov vs Deep Blue, the software was only known to be tweaked between games. This has been considered fair. The computer did have some minor unfair advantages, though.
Even if you feel Deep Blue cheated though, Kramnik, the world's champion, still lost to Fritz a few years ago. Fritz wasn't even the best program at the time, and the advantages were in Karmnik's favor, too. Nearly all GMs acknowledge that computers are stronger than them today.
I can't figure out what government subsidies you are referring to. The obvious one is the $7,500 that goes with each car, but I can't believe you expect that to be repaid or something. The early development costs went away in the bankruptcy, so they don't exist as far as new GM is concerned. How the remaining development costs are allocated to each car is a matter for accountants, and can probably be adjusted to create either a profit or a loss for each car.
All reports but this are saying that GM is breaking even on the Volt, which is pretty believable given its high price. Whether it's profitable or not probably depends on accounting rules. I expect they're really making a small marginal profit, but using Hollywood accounting to turn it into a loss.
Roentgenium is element #111, right below gold on the periodic table, and well within the zone of "highly unstable elements".
Elements 110 through 114 have long been expected to be an island of stability. The problem is that we cannot stuff enough neutrons in, as Rg 281 still has too few. So far, the heaviest isotope created is also the most stable. The only problem is that the odd atomic number elements are expected to be less stable, so that 110, 112 or 114 would be more believable. I don't think it's really likely that he has found Rg, but it's not impossible.
Rg, if it exists, would indeed be found as a trace element in Au.
The Earth's crust is tectonically recycled every several hundred million years (any given chunk has been subducted and recycled several times, more or less; we estimated this my first year of grad school, but I forget the numbers exactly), so you could only rely on the metals delivered in the past few hundred million years.
Just because the Earth's surface gets recycled every few hundred million years doesn't mean it all does. Diamond bearing kimberlite is usually over a billion years old, and much of the best iron ore is from when iron was precipitated from the ocean by the oxygenation of the atmosphere, two or three billion years ago.
The pertechnate anion is soluble and seems to be of some concern to those trying to permanently lock it away.
I liked his science fiction too, but I dropped this after the first volume. Too much death and maiming for my tastes.
The MSR reactors are neither liquid metal cooled nor water cooled. I don't see the relevance.
There is no cladding on the fuel.
This is not a fast reactor. It is thermal.
We don't have a lot of experience with molten salt reactors, which is a large part of what China is researching. Your criticism is at least premature.
India is not working on molten salt reactors, as far as I know.
Thorium will last as long as the Earth is habitable, as would Uranium in breeder reactors.

Sounds interesting, but I don't think I have time to read it now.

Statutory rape? It's often consensual.

I wonder how fast you could spin a nitrogen molecule before it falls apart? It should be calculable. Would hydrogen go even faster?
Yeah, C-14 dating is only good back around 60,000 years. You need to use uranium or other long lived isotopes for the age of the earth.
The star with the spiral is behind a self produced dust cloud. It makes it look more dramatic.
Stable means that no decay rate can be measured, which mean more than about 10^20 years (probably vastly more).

Just how stupid do you have to be to need a giant letter grade on a car? I hope that version doesn't fly.
Could you explain why then gasoline has an auto-ignition temperature of 280 while hydrogen is at 500? See here.
But how does installing a traffic light generate money to put in more traffic lights?
For those who don't know, the above post is referring to this.
But is there any practical difference? For instance, how many spaces are after this period. Did you guess 11?
The Spyder was $72.5k. But it won.
A metal-air battery doesn't have to carry its oxidant. So far the number of charges they can take is inadequate, but people are still working on them.
That is Grigori Perelman. There was no mention of him in the original link.
