Carbon nanotubes have improved existing technologies in fields ranging from electrical circuitry to architecture to materials science. So is it any surprise that when researchers in Arkansas applied the miraculous microscopic structures to tomato seeds, the plants grew faster, stronger, and more plentifully?
i agree with animemaster, they should try to see if its any improvement over other carbon forms. its a fairly well known fact that charcoal, when put into the ground stops nutrient leaching and increases the amount of water that can be held in the ground. not to mention charcoal is a lot less labor intensive to produce than nanotubes.
We've been closely following EEStor's potentially game-changing ultracapacitor--a technology that could allow for electric cars that charge almost instantaneously and drive hundreds of miles on a single charge. And if a purportedly "leaked" phone conversation from EEStor CEO Richard Weir currently making the rounds is legit, the long-in-development ultracapacitor has hit a breakthrough, and could be unveiled within months.
this just kinda pisses me off (no offense to anyone) we have flywheel enegry storage for years with rundown times measured over years. okay, yes im pretty positive its not as energy dense as lithium batteries, but they can be cheaper depending on what you make them out of whether it be carbon fiber of steel. but, they have recharge and discharge rates as fast as 15 minutes with out the use of chemicals and rare metals. not to mention if you take use of the gyro effects of a flywheel you can prevent a car from flipping or lose grip.
E. coli has earned a nasty reputation for upsetting stomachs and killing people. But now scientists at LS9, a start-up in South San Francisco, are putting the bad bug to good use, genetically engineering it to excrete biodiesel. The fuel "burns just like diesel," says Greg Pal, the senior director at LS9 [see Breeding the Oil Bug, about the rise of microbial biofuels].
you guys can be so skeptic when something new comes out. "2008", i gotta tell you somthing, your definitely right that it probably wont fit the demand we have, but theres not a way in hell electricity is much better. for one, most plants that make electricity are coal plants. two, solar panel have around 20% efficiency and even if there almost at a point were theyre finding better way to make them more efficient its still only going to be around 50% efficiency. and three, to make enough wind farms for gusts that come and go is ridiculous, and geothermal causes tremors, so scale that up and you got a hell of a problem, not to mention the world isn't full of spots for these places to be. so whats the worst thing about this, i see no car company making electric cars. dont you eat fruit and veggies also? those take alot of time to grow also, yet supply of them never dwindles. so really, right now, this is the probably one of the better things to do, give it a chance mr. 2008
Dan Lathrop needs a bigger Earth. His old one is two feet across and 500 pounds, about 20 millionths the size of the real thing. And after four years of tests, it failed to generate a magnetic field similar to the real Earth’s, which shields us from the sun’s radiation and guides some navigation systems by pointing compasses north.
yeah this article is rather awesome. umm, the on the pole switching thing, i dont know the exact time, but the mayans believed "the end of the world" to be in 2012. 2012 may not sound far off, but that may very well be the date for it. it would really be nice to know how the core really works
The existence of a race of sentient alien robots might be not just possible, but inevitable. In fact, we might be living in a "postbiological universe" right now, in which intelligent extraterrestrials somewhere have exchanged organic brains for artificial ones. The driving factor is a pragmatic desire to improve mental capacity. Alien beings may have already reached a point in their evolution where, having exhausted the potential of their biological brains, they have taken the next logical step and opted for robotic brains equipped with artificial intelligence.
i dont that there may be aliens who traded the biological brain out for mechnanical ones but what kind of set somthing off in our head that we may do this in a couple deacades of centuries as well. look it, i dont care that you may have more knowledge with a new brain, but what happens to our ability to reason? our wisdom and our morals? what happens to those? our brain is an amazing thing, to trade it out for some mechanical thing, sets me off a bit. if this ever happens in my life time, maybe when im like 50 or 60 (im 12 now), i would never trade out this beautiful thing above my eyes.
Is Formula One racing out of step with an auto industry whose greatest innovations have been in the area of fuel economy?
im so putting a flywheel kers on my car when i turn 16 lol
In a famous scene in the first Matrix movie, a character takes a bite out of a juicy steak. He knows it's not real, but enjoys it anyway. In some ways, a video game -- just moving pixels on the screen -- is a similar virtual reality experience. No, the aliens in Halo 3 are not real, but we pretend they are. That is how a game can pull you from a living-room couch into a foreign realm.
i was addicted to a video game, but now i quit litterally tonihgt
hoorganvisor, that gas is so deep under the ocean that the water above it and the chilling temperatures cause it so that it realeses the littlest amount of methane. only when we bring it to the surface does it become deadly
As the earth warms and our hunger for oil and other natural resources grows, the Arctic—once a peaceful repose for Santa—is already a crisscross of territorial claims that could get even more complicated in coming years according to a new map drawn up by researchers at Durham University, who say it is the only geographically accurate map of its kind.
why is it that even though we know this oil is one of the causes for global warming, why do we hunger it more? and better yet why do governments not take much action. i fell as though they try to hide it up. a couple of weeks ago i read an article about cheney destroying some pages of a report that had information in it about the heath concerns about global warming. like seriously, everyone talks about going green, then why isnt it happening?
And you thought Bop-it was fun? British kids in parks around the country are playing a mega-scaled version of the addicting game that burns calories while they play.
what ever happened to to just playing tag? hide and go seek? pickle? you dont need electronics to live
