Anyone else notice that they seriously restricted the throughput to/from the drives based on their choice of SATA cards (good old 32-bit PCI 2.3 only has max theoretical of 266MB/s, and the same goes for PCIe 1x [250MB/sec])? In the worst case scenario, each drive is at max getting 17MB/sec of transactional bandwidth, which is just pathetic (based on some very back of the envelope calculations). For the amount of money they spent on making a custom solution, an extra 100-200 bucks to get a few 4-8 lane PCIe sata cards is a pittance. Overall, it just demonstrates to me, at least, a poor understanding of what goes into making a good storage solution.
And dont get me started on the the lack of backup power supplies, error checking ram, etc.
Quick comparison:
Charge time: Ultra capacitor (Charge time of 1 second [practically limited by the amount of juice you can deliver] versus 30 minutes-8Hrs)
Lifetime: Ultra capacitor (Infinite [your drive train will go before these do] versus ~10 years, depending on who you believe)
Availability of construction materials: Ultra capacitor (Can you say carbon and aluminum? This is versus a handful of countries that control the worlds supply of lithium, some of whom's governments are not on the best of terms with us, whatever their reasons may be).
Someone remind me why we aren't throwing billions of dollars towards ultra capacitor development? Quite literally, it is the only practical solution to the electric car question.

The article is so bad as to not even be publishable. They see less 1,2,4-trimethylbenzene in aged samples? Guess what, trimethylbenzene evaporates slowly. Less soluble? Ever heard of decomposition?
There's a reason this isn't in Science or JACS, and that's because its complete and utter fantasy.
is that after reading the article and the comments, our brains committed suicide. Christ on a cross, people get funded for wastes of time like this, and friends of mine cant get a dime for research.
Ill say this, this 'technology' is going nowhere. Hell, Ill save them the catalyst and use lithium aluminum hydride. Any chemistry student worth their salt remembers that H:- donor + H2O = H2 and OH.
Been known for a very long time. Borohydride is more stable, and cheaper than the aluminum hydrides (hence the catalyst), but for god sakes, its still expensive (2 kilos is about 500 bucks) and I doubt that they can find a way regenerate in situ. Great way of making H2 on the spot, but not in any fashion where you need to recharge your supply quickly./rant
Someone was using leprosy as a comparable, incurable, illness. Sorry to break it to you, but leprosy is curable, and it doesn't make body parts fall off (though it does slowly mutilate the dermis). Check Wikipedia if you don't believe me.
Also, these symptoms do sound like schizophrenia. I wonder what age group this is occurring in? As I recall, the DSM says that schizophrenia typically targets 18-30 year olds (or at least they have their first schizo typical episode in this age range). Not sure what is causing it, it could very well be some side effect of Lime disease messing with neurochemistry, which would explain both the anti-psychotics and antibiotics working (one would treat the symptoms, the other the causal agent).
are immediately dumped into the trash. Its not even journalism. When I went to high school, the school newspaper was better written. At least they would check the facts and care about accuracy (somewhat). EVERY article that I have seen from opensourceenergy has been debunked in about 20 posts on slashdot, and even before we have our morning coffee! Its that bad. Just... junk it. And senior mods need to sit Scuttlemonkey on their knee and explain the birds and the magnetic flux density to him.
but they forgot basic physics
ke=mv^2, so for a doubling in velocity, the ke will quadruple, not octuple
(unless of course there are added efficency gains from increasing rotor speed, but I doubt it) I call bunk.
about Cingular/ATT. Ill tell you this, Cingular is the only company that gets a signal in the building I work in (Phys/Chem dept.) The building is circa 50's construction with cinder blocks, and basically functions as an imperfect Faraday cage. I get signal in the NMR room, which in addition to having tons of EM running around, has to be shielded because of it. Only room I cant get good signal in is the X-Ray room, oddly enuogh. Good luck to the Verizon/Sprint guys trying to get a signal anywhere that isnt right next to a window (like the hallway right next to the labs).
Both of these guys have publications (100+ a piece assuming that I have the right guys) and for the most part they appear to be Tier-I and II journals (peer reviewed materials). What strikes me is that Keramidas isnt a battery chemist, he's a thin film semiconductor/ferroelectric materials guy. Abraham is just what the article says, a electrochemical researcher with lots of publications in Li based materials.
