Battery Battle

A new type of redox flow battery from the Fraunhofer Institute for Chemical Technology (ICT) offers an advantage for electric cars. If the rechargeable batteries are low, the discharged electrolyte fluid can simply be exchanged at the gas station for recharged fluid – as easy as refilling the gas tank.

Making Renewable Hydrogen From Wastewater At California Winery

Penn State researchers are demonstrating a renewable method for hydrogen production from wastewater at the Napa Wine Company in Oakville, CA. The refrigerator-sized hydrogen generator will take winery wastewater and - using bacteria and a small amount of electrical energy - convert the organic material into hydrogen.

Will satellite radio ever live up to its commercial expectations?

This week's question concerns satellite radio. When the first U.S. digital satellite radio service was launched in 2001, many people predicted that satellite radio would someday dominate the airwaves, eclipsing all other forms of radio broadcasting. Most of the major automakers rushed to sign satellite radio installation agreements, broadcasting company stock prices soared, and the competition for new subscribers was fierce. But almost a decade later, major satellite radio broadcasting companies like Sirius XM are still struggling to make a profit and, in some cases, losing subscribers. Supporters of the medium claim that satellite radio is just taking longer than expected to catch on, while its detractors argue that, like CB radios, it was a fad whose window of opportunity has passed.

What do you think? Will satellite radio ever live up to its commercial expectations?

Lowering Solid Oxide Fuel Cell Cost

Georgia Tech researchers have developed a new ceramic material that could help expand the applications for solid oxide fuel cells – devices that generate electricity directly from a wide range of liquid or gaseous fuels without the need to separate hydrogen.

Will technology advance to the level of robots replacing people in day-to-day life?

Will Robots Ever Replace People in Day-to-Day Life?

This week’s question concerns robots. Scientists are saying that humanoid robots like those seen in the new movie "Surrogates" are not that far from reality. In the movie, realistic robots take the place of people in day-to-day life and no one worries about crime or pain, as their robots can self-heal. In the real world, armies use remote-controlled robots to attack enemies and destroy land mines. Anybots - a Mountain View, CA company founded in 2001 - currently offers a 35-pound, 5-foot-tall robot that allows the user to be two places at once and remotely travel, see, hear, and talk. What do you think? Will technology advance to the level of robots replacing people in day-to-day life?

Could Small Springs Beat Batteries?

MIT scientists have found that carbon nanotubes could be formed into tiny springs capable of storing as much energy, pound for pound, as the best lithium-ion batteries - potentially more durably and reliably.

Will electric vehicles finally take off?

This week’s question concerns electric vehicles. For decades, electric vehicles have been touted as the solution to zero emissions motoring. However, costly batteries and the lack of a supporting infrastructure have stunted electric vehicle development. U.S. and offshore automakers continue to step up electric vehicle development, and some say they expect limited production electric cars to emerge in the next few years.

What do you think? Will electric vehicles finally take off?

Yes or no?

A Natural Clean-Up Technology

Researchers at North Carolina State University are demonstrating that trees can be used to degrade or capture fuels that leak into soil and ground water. Through a process called phytoremediation, plants and trees remove pollutants from the environment or render them harmless.

Algae Blooms Broaden Battery Possibilities

Blooms of Cladophora algae may be troublesome, but they do have a positive side. Researchers at the Ångström Laboratory of Sweden's Uppsala University have discovered that the cellulose nanostructure of these algae can serve as an effective coating substrate for use in environmentally friendly batteries.
