Buckyballs Can Store Concentrated Hydrogen
Pickens brings news that researchers from Rice University have discovered that it's possible to store hydrogen inside buckyballs. Hydrogen can be an excellent power source, but it is notoriously difficult to store. The buckyballs can contain up to 8% of their weight in hydrogen, and they are strong enough to hold it at a density that rivals the center of Jupiter.
"Using a computer model, Yakobson's research team has tracked the strength of each atomic bond in a buckyball and simulated what happened to the bonds as more hydrogen atoms were packed inside. Yakobson said the model promises to be particularly useful because it is scalable, that is it can calculate exactly how much hydrogen a buckyball of any given size can hold, and it can also tell scientists how overstuffed buckyballs burst open and release their cargo."

it can also tell scientists how overstuffed buckyballs burst open and release their cargo."
Well, if these are being burst open, then it means that these have to be built AND loaded each time, and then disposed. So now, we are going to either break apart water (cool, but inefficient), or strip H from fossil fuel (efficient, but bad news for the CO2). Then we are going to build bucky balls, store the hydrogen in it (at 8% volume), sell you the buck ball, your car will magically break the balls (most likely pressure or heat), this will power either an ICE (very low efficiency) or a fuel cell/electric motor (high efficiency, but high cost due to fuel cell).
Of course, we could just take the electricity and charge a battery and then run an electic motor, all at more than double (or even triple) the efficiency and probably half to one third the costs.
I prefer the "u" in honour as it seems to be missing these days.
...but each burst buckyball is 60 carbon atoms floating around in your fuel. Aren't you right back to "hydrocarbons" if you burn this fuel, and won't the carbon poison fuel cell membranes? It's a cool trick _iff_ you can strip the carbon out efficiently before the hydrogen is used.
Tiller's Rule: Never use a word in written form that you've only heard and never read. You will end up looking foolish.
So all we really need is a really big buckyball, and we've solved the hydrogen storage problem.
Of course, we still need to figure out how to get the soft gooey hydrogen inside the chocolatey pocket of the buckyball, especially at "center of jupiter" pressures. Maybe the folks at Cadbury might reveal their secret. We'll also need to figure out how to get the hydrogen out once we're ready to use it.
When our name is on the back of your car, we're behind you all the way!
An alternative to carbon-fuel which requires storing that alternative in carbon?
Once you crack those buckeyballs open to get the H out, the C has to go somewhere, right?
What am I missing, here?
Why, oh why, didn't I take the Blue Pill?

In the nuclear fuels field, we deal with really exotic temperatures and pressures in materials whose bulk properties might be only two or less orders of magnitude from standard temperature and pressure. Did you know that there are people sitting around, calculating the pressure of an individual helium atom in a crystal lattice? The pressures that arise put planetary cores to shame.
Let's RTFA a bit: "'Based on our calculations, it appears that some buckyballs are capable of holding volumes of hydrogen so dense as to be almost metallic,' said lead researcher Boris Yakobson"..." If a feasible way to produce hydrogen-filled buckyballs is developed, Yakobson said, it might be possible to store them as a powder."
What a difference one word can make in a summary. News flash, "Miss Universe can have sex with Slashdot users! According to simulations conducted with fold-out pictures in Randy's basement..um...research center"
The simulation work is pretty cool, the headline and summary can and does mislead the reader.

One thing is that theoretics will blow singularities out the window. One theory holds that Jupiter's core is a solid mass of crystallized carbon. Yep, you can guess what that is, Diamond. Another theory, with a more stable foundation, is that hydrogen at that pressure and temperature, becomes metallic. Essentially within your little buckyball, you would have a sphere of hydrogen metal. If your buckyball can handle > 100GPa,(over one million atmospheres) then the hydrogen atoms will undergo a phase change and become metallic.
If this is practical and it's energy potential can be tapped, we'll have at our fingertips, an unlimited power source that won't kill you with radiation.

Okay, no one in a modded-up post on this story understands the concept. Buckyballs look like soot. You have a tank filled with this soot in your car. Then you flow very high pressure hydrogen gas over them for awhile (this has been done for years with carbon nanotubes, which offer more storage but because they only confine in 2 dimensions, unlike the balls, they don't provide the capillary forces necessary to make this easy). Hydrogen then adsorbs (notice ADsorbs, not ABsorbs) onto the inner surfaces of the Buckyballs. Capillary forces, like those that cause liquid to be drawn into a straw, allow the hydrogens to live essentially as liquids inside the balls, meaning that when you remove the high pressure hydrogen flow, the hydrogren in the buckyballs doesn't all immediately fly out. Hydrogen leaks out of the balls slowly, becoming a gas and maintaining a roughly constant pressure in the tank, and you then siphon off the hydrogen that you want to power your car. You can control the leakage rate by changing the temperature.
You then reuse the Buckyballs by flowing hydrogen gas over them when they're empty. They're 100% reusable storage, not tiny gas tanks. Someone mod this up so that the dozens of "oh nos, Buckyballs hurt teh environments" posts go away.

Wake up world. Hydrogen isn't a source of energy any more than capacitors are. It's a way to store energy.
-- QED
Well, this seems to be purely theoretical work about whether buckyballs *could* contain dense hydrogen, not how to achieve it. However, I can think of two very interesting possibilities, energy-wise, if it could be achieved.
1) Superconductivity: Metallic hydrogen is a superconductor. Not sure how that would work conducting current through the shells, though. While just being a superconductor doesn't give you energy, it makes it easier to transmit energy.
2) Fusion is all about the combination of the density of your targets and energy of your collisions. This is some impressive hydrogen density being discussed.
That was either the start of something bad or the end of something stupid.
