Nanotech Ink Turns Paper Into a Low-Cost Battery
jangel writes "Stanford University researchers have demonstrated a way to turn ordinary paper into a battery, which may be crumpled or pressed into any form. It's said the technology promises greater durability, higher efficiency, and faster energy transfer than traditional batteries. The technique uses special ink made of carbon nanotubes and silver nanowires. Thanks to the small diameters of these materials, the ink sticks strongly to the fibrous paper, allowing the battery to be extremely durable. The paper battery could last through 40,000 charge-discharge cycles — at least an order of magnitude more than lithium batteries. According to the researchers, the paper batteries will be low-cost, may be crumpled or folded, and can even be soaked in acidic or basic solutions, yet their performance does not degrade. 'We just haven't tested what happens when you burn it,' one of the researchers quipped." This is the same Stanford research team, lead by Yi Cui, whose work with nanotechnology for battery applications we have discussed before. We've also delved into alternate routes to the holy grail of the ultra-thin battery.
Bullshit. Blacks invented the potato chip, the mailbox, the gas mask, and the Jheri Curl among other things.
Racist scum.
God help me for entering into a racist off topic flamefest, but...
There's plenty of rednecks in my neighbourhood with white children who are far less civilized and more ignorant than a number of non-white children I've met. Believe it or not, there ARE black people who don't worship ignorance and violence and surprisingly enough, they raise their kids with the same attitudes.
Now, take a black kid and have him raised by rednecks (assuming the rednecks would take him) and you'd still get a thug... probably with a rifle and a buck knife instead of a handgun, but still a thug.
Your 'anti-racist' response had quite a bit of racist attitude in it.
On the other hand, you have to be careful not to cry 'racist' too easily - you get too touchy about it and then you can't even investigate things like whether the average Kenyan has a mechanical advantage that leads to better performance in marathons...
a couple of centuries of wars and european (and, post-WW2, american) imperialism fucked up their culture and sent them into their version of the Dark Ages - which they're still in now....and unlikely to get out of it any time soon because we (the "West") keep on undermining their secular, progressive political movements and propping up loony religious dictators to keep them there.
