The name change to reflect nanotech emphasis was a good move and is likely to increase investor awareness. Longterm, it's more important that being able to store hydrogen in carbon nanotubes will beat the pants off of any other storage technology being looked at for hydrogen-powered cars of the future. The gist of nanotube storage comes from the fact that hydrogen is literally the smallest atom that exists and the H2 molecule is the smallest molecule that exists. So small that hydrogen molecules can drift right through solid metal while causing the lattice structure of the metal to degrade ("hydrogen embrittlement" See corrosion-doctors.org ). And if the hydrogen is under pressure it leaks through even faster. Let's see: explosive hydrogen leaking through the storage tank while you drive down the road... Not in my car! To avoid this problem, most engineers looking at storing hydrogen for use as an alternative fuel had (up until Nanergy's patented idea of storing it in carbon nanotubes!!) planned to temporarily lock the individual hydrogen atoms into a metal hydride (sometimes nickel but usually a more expensive metal priced by the ounce) and release the hydrogen as needed. Nice and safe since the bonded hydrogen is no longert explosive, but the problem with this approach is that energy is required to first make and then break the covalent bonds that lock the hydrogen into the metal. Which means having to expend a certain amount of energy to break loose every single atom of fuel. Nanergy's solution is extremely elegant. Since carbon is the smallest tetrahedronal-shaped atom (think of three oranges in a triangle with a fourth orange resting on top of the triangle), a one-atom-thick fiber of carbon uses two of its four valence points to link the atoms into a chain, leaving two valance points available to link each chain to the ones on either side of it. Link up those chains into a circle and you've got what amounts to a hose made of fibers so small and so close together that there's literally no way that a hydrogen atom can squeeze between them. Also as safe as metal hydride (since oxygen can't get in to make it explode) without having to pay an energy penalty since the hydrogen is "loose" inside the tube rather than being chemically bonded to the tube. It's like a garden hose full of water. You put pressure at one end or vacuum at the other and the hydrogen simply flows to where you want it. My hunch is that if hydrogen ever comes to replace gasoline, every car on the road will mean royalties flowing to Nanergy. Which should translate to dividends flowing to stockholders and a price per share that would sound absurdly high from today's level. Just how I see it.... Gordon
