The volume to power of hydrogen is still far too low compared to batteries. Otherwise this could be the breakthrough that finally gets fuel cell cars going - self regeneration of (some) power during the day.
Because their billing structure would put the power company out of business if they allowed it.
Note that while can't go net negative for the year he can get to net 0. Also note that he's 'selling' back power to get to that net 0 at retail rates.
The places that allow you to go net negative buy your power back at wholesale rates, which is far lower. If you think about it when you sell power back to the power company you're not competing with the power company, you're competing with the power generators. Why should the power company give you an unfair advantage there?
Because each core is no longer task switching. Once you have more cores than tasks you can remove all the context switching logic and optimize the cores to run single processes as fast as possible.
Then you take the tasks that can be broken up over multiple cores (Ray Tracing anyone?) and fill the rest of your cores with that.
The bacteria became a new species.
E.Coli can't digest citrate. That's one of the properties that define it as 'E.Coli'. This new species can. It is thus no longer 'E.Coli.
linear time factorization cannot be achieved without a quantum computer. Without a linear time factorization algorithm a 1024-bit RSA encryption would take a government organization with millions in dedicated hardware decades to crack.

millenia, maybe centuries depending on how computational power advances. Then again unless it's also randomizing the keys the first time they sell a decrypter (assuming they actually do and don't just take your money) the anti-virus companies will get their hands on it and plug that into the 'clean' function for this virus.
Actually given that they've got a new Lead Programmer who's quite hellbent on making the game what it should have been in the first place I don't doubt it's night and day.
After all Brad isn't stuffing all the venture capital up his nose this time.
That depends on how many voices join the chorus. If we can gather more support than just/. and a few other sites and either take this mainstream or at the very minimum keep gathering steam then we can hold out until the next administration.
No matter what things will be changing come 2009. We have no idea how they're going to change, but change they will.
Actually if you break down the cost of gasoline in the US right now you get this:
http://www.energy.ca.gov/gasoline/margins/index.html
And you see that the cost of crude oil - pre-refine, pre-distribution, pre-everything is spiraling quickly to $3/gallon (it's at $2.80 right now)
If this can produce the effective equivalent of light sweet crude for $2/gal then screw any more improvements get that into full scale industrial production right now. We can get it more efficient once we stabilize the world oil and food markets.
We haven't had crude at $2/gal since Dec of last year and I personally would love to see gas prices drop back below $3/gal at the pump please.

I can see them checking your person before getting on a plane to make sure you're not carrying weapons... but what on your laptop could possibly endanger an airplane?
They did it because 2.0 was already unlocked. I honestly expect them to end the beta program and release something quite different that's only been tested internally to prevent this same thing from happening.
(it'll fail, but they'll try)
All they have to do is supply a good compiler and you can build all of those from source. If you can compile them then so can IBM (who will most likely be supplying Cell Linux).
Simple - becasue they will get FOSS people to help them with the API's. Not only that but this means that there is already a Linux ported to Cell, so that's proof that it works for IBM to start selling Cell PC's.
All in all it doesn't cost them much to put it on the HDD but they get good press, a few more sales, and most importantly free dev work to advance the software for Cell (compiler, graphics API's for the chipset that the PS3 uses etc).
Remember - this thing won't run Direct X and programming for that many processors (and taking advantage of them) is a real problem. Sony needs all the help it can get.
You aren't getting something for nothing, you're using that wonderful E=MC^2
Every pair of atoms that fuse in a standard fusion reaction liberates an emormous amount of energy. Look at the atomic weights of Deuterium and Tritium, then at the atomic weight of a single neutron and at Helium.
The difference between the two is being converted into energy. That's where the power's comming from.
So yes, if you can break the 1:1 barrier then you can plug it into itself and it will keep running. Just like a power plant keeps running... as long as you provide fuel.
In this case the fuel is hydrogen isotopes. The good news is that both isotopes are plentiful (or can be generated easly) on earth, thus the comment of nearly limitless inexpensive energy.

You think Global Warming is bad now... and you want to add more energy to the system that's not already there?
E = MC^2

You're forgetting that we need to triple the power distribution capacity if we're going to move to electric cars.
Moving everyone to solar on their roof and selling at wholesale to the electric companies may prevent the trilians needed to do those upgrades.
