Air-Fueled Battery Lasts 10 Times Longer

Air-Fueled Battery Lasts 10 Times Longer

Oxygen drawn from the air reacts within the porous carbon to release the electrical charge in this lithium-air battery. 

A new type of air-fueled battery could give up to ten times the energy storage of designs currently available.  This step-change in capacity could pave the way for a new generation of electric cars, mobile phones and laptops.

Harnessing Direct Solar Power To Propel Tiny Nanomaterial Machines

Harnessing Direct Solar Power

A four-finned rotor (center) floating on a pool of water spins when exposed to sunlight.

The sun is the most abundant source of renewable energy. But all the technologies that capitalize on sunlight, including photovoltaics and biofuels, require intermediate steps and infrastructure to turn the sun’s rays into something that can be used to perform work in a machine. Researchers at the University of California, Berkeley, are using carbon nanotubes to build small, simple waterborne machines propelled directly by sunlight. In theory, they say, these machines could be scaled up to make energy-generating pumps directly powered by the sun.

Samsung Fuel Cell Battery Ready for Market

 Samsung Fuel Cell Battery Ready for Market

Amazingly light and efficient fuel cells

Samsung’s been toying around with fuel cell batteries for about three years, but now it means business. Rolling out first to the military, this ethanol-powered fuel cell is set to power military paraphernalia next year. But it’s not going to run laptops for a month as originally promised. (Pics)

Cheaper And More Reliable Lithium-Ion Batteries

Cheaper And More Reliable Lithium-Ion Batteries

Lithium-ion cells that use polymer electrolytes can be affordably packaged in compact, flexible pouches  

A new incarnation of lithium-ion batteries based on solid polymers is in the works. Berkeley, CA-based startup Seeo, Inc. says its lithium-ion cells will be safer, longer-lasting, lighter, and cheaper than current batteries. Seeo’s batteries use thin films of polymer as the electrolyte and high-energy-density, light-weight electrodes. Lawrence Berkeley National Laboratory is now making and testing cells designed by the University of California, Berkeley spinoff.

Nanoball Batteries Could Recharge Electric Cars In Minutes

Nanoball Batteries Could Recharge Electric Cars In Minutes

 A sample of the new battery material.

Researchers at MIT have designed a new battery that can recharge devices about 100 times faster than conventional lithium ion batteries. The design could lead to electric car batteries that charge in 5 minutes (compared with 8 hours in today’s electric cars) and cell phone batteries that charge in just 10 seconds.

Lumitop: Fiber Optic Illuminated Clothing

Lumitop: Illuminated Clothing 

 Lumitop

Fiber optics are, well, fiber. Makes sense to weave those fibers into haute couture fashion clothing. Not exactly designed for shrinking violets, the Lumitop clothing line will make a statement on any dancefloor or red carpet. Check out the gallery below for more samples of this latest stab at tech fashion. There’s even something for the guys… well, only if your name is “Gunther.” You have to wonder where the battery pack goes.

SATY MP3 Player Also A Breathalyzer And Mosquito Repellant

SATY MP3 Player Also A Breathalyzer And Mosquito Repellant 

SATY MP3  

CES has big, fancy products like the new Palm OS, and then they have stuff like this. In a little pod in the Sands, a Chinese company called SATY is showing this rather blocky music and video player with some unusual features. It’s got a flashlight. It’s got a radio. It’s got a mosquito repeller (which just means it plays a really high-pitched tone, so it’s probably also a teenager repeller.) It has a breathalyzer.

Vent-Miser Programmable Energy Saving Vent

Vent-Miser Programmable Energy Saving Vent 

Vent-Miser 

Having central heating is easy and convenient, but not very cost effective. For one thing, you’re heating rooms that are not in use. Most homes do not need every single room to be the same temperature. hat’s where this device comes in handy. The Vent-Miser Programmable Energy Saving Vent saves you money by controlling individual room temperature.
