I can't wait until tech like this comes to market. The pace of research just keeps accelerating and given the average ~10-15 year turnaround to market, we are going to start seeing some awesome advancements / new products at an ever increasing rate.

No. Not even slightly. It is the same material used in standard pencils (leads). Try and get that to burn. Even a blow torch as no effect!

Would like to see some number's on power consumption, most of the power consumption of FET's come from the gate leakage, from what little I read it sound's like the new construction method along with the carbon itself will vastly improve that, with silicon as lithography processes have gone smaller power consumption has remained relatively static due to balancing lower voltage requirements with increased current consumption. And why this focus on RAM? Solid state storage using this technology will finally signal the end of over 6+ decades of magnetic disks for primary storage.

No, the carbon would not float away. You're thinking of carbon's molecules with oxygen.

You might be able to get it to burn at extremely high temperatures and in very high oxygen environments (might need pure or almost pure oxygen), but not in any situation that's even remotely likely with use of it in electronics. If you're asking this question because of carbon monoxide and carbon dioxide, well from what I know of them, they are generally made by burning chemicals that have carbon in them, not burning carbon itself.

Then buy an extended battery. Amazon often has them for dirt cheap for a wide variety of phones and my Evo 4G Android phone lasts two to three days of heavier usage with it and much longer with light usage.

I did that once with a lighter. It wouldn't burn, but after a minute or two with a lighter, a piece of .7mm lead from a mechanical pencil did explode. It left a few very small scorched holes in a carpet that was a few feet away and the holes had little pieces of graphite shrapnel. Admittedly, it was far from being my brightest idea and could have had much worse results. However, like you're saying now, it didn't actually seem to burn the pencil lead. i'm not sure of why it exploded, but if I had to guess, there might have been impurities that caused it.

When last I checked (admittedly, a decade ago), C-60, or Buckminsterfullerene ("Bucky Balls") was not possible to manufacture. It could be detected in trace amounts when burning various fuels, if I remember correctly, but it was only a minute percentage of various other forms of resultant carbon, all mixed together. Does there now exist a way to manufacture and isolate economically feasible amounts of C-60?

We've been able to manufacture graphene, fullerenes, nanotubes, etc. etc. for quite a while now, granted this might not be the easiest/cheapest thing to do. I don't know if it is economically feasible, but we've been improving with this sort of work very much and it might be. If transistors made from them can be produced on current fab's technology like these scientists claim, then it would seem that we can manufacture them fairly well.

Logically, a smaller and more compact RAM chip consumes less power.

in fact as memory could consume up to 20% of your battery, better Memory also implies more battery life ;-)

no, its a crappy time to be a nerd. most of the advancements we would have loved to be part of happened long ago, and its going to take a hell of along time before the advancements get far enough again to be interesting... unless you are in an academic environment.

Why is it almost always Israelis that make the latest technological breakthroughs? Is it because they are vastly outnumbered by the horde that they know if they didn't have superior technology then they would be overrun? I'm wondering if it would be better if the horde keeps threatening them or stops.

A lot of discoveries, perhaps most, are made in other nations. We might hear about more Israeli discoveries/inventions/whatever, but even that doesn't seem true. Perhaps you've simply read about a few Israeli scientific breakthroughs lately instead of other discoveries. Tom's doesn't cover even nearly all of them.

Yes, everything is combustible if the temperature is high enough, but the temperature it would combust would be significantly higher than what would cause you to set on fire first and even be completely reduced to ash, so try not to worry about it

Methinks there's a hidden agenda in your statement, would you even have raised this question if the breakthrough had happened in Manchester in the UK? That city had the first working computer, invented the contaceptive pill, first split the atom, two Manchester University scientists won the 2010 Nobel prize for physics for their graphene research, other famous scientists from Manchester include John Dalton, James Prescott Joule, Ernest Rutherford and Bernard Lovell.

But because Israel is mentioned in the story are you pushing some kind of antiSemetic angle?

Not sure about the "horde" theory, but Israel does have a lively high-tech industry. Lots of education, R&D, and the like over there.
