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?
