audiobytz - biweekly e-newsletter: "Building a test capacitor out of curved graphene sheets produced a device with an “specific energy density” of 85.6 Wh/kg (watt-hours per kilogram) at room temperature. A practical graphene battery would have a capacity of around 28 Wh/kg. Nickel-metal hydride (NiMH) batteries have an energy density of 40-100 Wh/kg, while lithium-ion batteries (used famously in PCs, cellphones, and MP3 players) top them both at 120 Wh/kg. But since NiMH or lithium batteries are often operated in the middle range of their discharge cycle, only 20 to 50% of their capacity is actually used. So a graphene capacitor “battery,” with the potential of being charged in seconds or minutes and which do not suffer from degradation upon recharging over possibly millions of cycles– they store energy electrostatically (by the accumulation of electrons) and not chemically – might become competitive for many applications. The illustration shows how the capacitance of the lab prototype (in farads/gram) varies – or, rather, hardly varies, over as many as 500 charge-discharge cycles. A typical chemical battery would have a detectable downward slope in as few as 100 cycles (hence the interest in iPod battery replacement)."

Welcome To Graphene Supercapacitors
Curves are the key:
How's That French Lit Degree Working Out?
Answering My Critics On The Subject Of The College Bubble Page 3 of 3 - Forbes.com: "At some price point, things will shift, and the following answer will become a common and respectable one: Nowhere. 'We took a fraction of the money that we would have spent on college and set them up in businesses of their own, and they're doing quite nicely, thank you. By the way, how's that French Lit degree from Vassar working out for your daughter? Is she still working at Nordstrom's?'"Heh.

Allow Me To Restate That Number
Federalist Paupers » Blog Archive » Why the Terrorists Can Never Win: "The state of Wisconsin has gone an entire deer hunting season without someone getting killed. That’s great. There were over 600,000 hunters.Did I forget to mention that the tranzis -- and now apparently the TSA -- are completely untethered from reality?
Allow me to restate that number. Over the last two months, the eighth largest army in the world – more men under arms than Iran; more than France and Germany combined – deployed to the woods of a single American state to help keep the deer menace at bay.
But that pales in comparison to the 750,000 who are in the woods of Pennsylvania this week. Michigan’s 700,000 hunters have now returned home. Toss in a quarter million hunters in West Virginia, and it is literally the case that the hunters of those four states alone would comprise the largest army in the world."

It Couldn't Happen To A Nicer Bunch Of Goons
Faster, Please! » Iranian Chaos: Spontaneous Revolt Against the Regime: "The port of Bandar Abbas is one of Iran’s major shipping hubs, as well as a big naval base in the Straits of Hormuz, and the site of a big refinery. It is now in chaos. Thousands of trucks, many of them loaded with imported foodstuffs, commercial goods of all description, and even oil products, have blocked the city’s roads, effectively ending all movement in and around the port. The drivers simply shut down their rigs, took the coils out of the engines, and walked away. On the water, there’s a similar shutdown of the hundreds of small boats and ferries that usually carry thousands of people each day to the nearby islands as well as to Dubai. They have clogged the harbor, and nothing is moving."
A Hell
I'm guessing you'll see a report on this from the Obamedia when you know where does you know what. Which come to think of it seems to be happening as we speak...
Ace of Spades HQ: "The Military's Real 'Don't Ask - Don't Tell' Problem
Is that the Afghan Pashtun men won't stop fucking each other and little boys:The report described unease by U.S. Marines and British soldiers who felt they were being propositioned, or who were outraged by apparent acts of pedophilia by Afghan soldiers and police. It documented one case in which 12 of 20 Pashtun interpreters working with one U.S. Army unit had contracted gonorrhea from homosexual encounters.
And using young boys for sex creates a cycle damaging to boys and young men and also to the women"

GIGO+ Update
Why the plus? Because Garbage In, Garbage Out at least assumes that the code isn't garbage also:
Model Charged with Excessive Use of Forcing | Watts Up With That?: "Yes, as I have written about extensively. The state of GISSE, or any of the other models I have inspected, would not come close to passing muster anywhere I have worked (except Gov.). I have been designing and developing software for something closing in on 30 years now, even in the early days we maintained higher levels of controls and scrutiny. Today it is mandatory, or you don’t eat."
