Berkeley Lab Startup Brings Fuel Cells to the Developing World

Point Source Power’s cheap, rugged fuel cells can provide electricity where none exists.

In some parts of the developing world, people may live in homes without electricity or toilets or running water but yet they own cell phones. To charge those phones, they may have to walk for miles to reach a town charging station—and possibly even have to leave their phones overnight. Now a startup company spun off technology developed at Lawrence Berkeley National Laboratory (Berkeley Lab) has created a simple, inexpensive way to provide electricity to the 2.5 billion people in the world who don’t get it reliably.

Point Source Power’s innovative device is based on a solid oxide fuel cell that is powered by burning charcoal, wood or other types of biomass—even cow dung—the types of fuel that many in the developing world use for cooking. The fuel cell sits in the fire and is attached to circuitry in a handle that is charged as the fuel cell heats up to temperatures of 700 to 800 degrees Celsius. The handle, which contains an LED bulb, can then be detached and used for lighting or to charge a phone. (more…)

The politics of climate change

U.S. residents who believe in the scientific consensus on global warming are more likely to support government action to curb emissions, regardless of whether they are Republican or Democrat, according to a study led by a Michigan State University sociologist.

However, a political divide remains on the existence of climate change despite the fact that the vast majority of scientists believe it is real, said Aaron M. McCright, associate professor in Lyman Briggs College and the Department of Sociology. (more…)

Invasive Crazy Ants Are Displacing Fire Ants, Researchers Find

AUSTIN, Texas — Invasive “crazy ants” are displacing fire ants in areas across the southeastern United States, according to researchers at The University of Texas at Austin. It’s the latest in a history of ant invasions from the southern hemisphere and may prove to have dramatic effects on the ecosystem of the region.

The “ecologically dominant” crazy ants are reducing diversity and abundance across a range of ant and arthropod species — but their spread can be limited if people are careful not to transport them inadvertently, according to Ed LeBrun, a research associate with the Texas invasive species research program at the Brackenridge Field Laboratory in the College of Natural Sciences (more…)

Tablets: An ideal vacation companion

Sleek, light, long-lasting and with a dazzling array of apps, today’s tablets have become an indispensable tool for travelers.

REDMOND, Wash. — Packing for summer vacation used to be quite a chore, but today a new travel companion is removing a lot of the guesswork and lightening the load. Travel guides? Check. Books? A whole library. Movies, music and games for the kids? Got ‘em. Map, compass, calculator, and even Office 2013 so you can get a little work done? Of course.

The best part is that it all comes in one small package. Sleeker, lighter and with more battery life, today’s tablet PCs are the perfect way to navigate new cities, stay entertained on the train, and keep connected to the office while you’re on the road. A tablet paired with a keyboard (or a convertible with a keyboard built in) can help travelers both work and play while away from home. (more…)

Brick by brick

Professor, author Robertson discusses innovation evolution at Lego

When you hear Lego, if all you think about are shiny, plastic bricks and toys, think again. From a toy concept brought to life by a carpenter to tales of failed innovation truths that mirrored a Greek tragedy, the Lego story is about innovation and evolution, David Robertson told attendees at last week’s Chaplin Tyler Executive Leadership series lecture.

Robertson, professor of practice at the Wharton School at the University of Pennsylvania, presented “Rebuilding Lego” to 80 students, faculty, staff and community members on the University of Delaware’s Newark campus. (more…)

Study of the machinery of cells reveals clues to neurological disorder

Investigation by researchers from the University of Exeter and ETH Zurich has shed new light on a protein which is linked to a common neurological disorder called Charcot-Marie-Tooth disease.

The team has discovered that a protein previously identified on mitochondria – the energy factories of the cell – is also found on the fat-metabolising organelles peroxisomes, suggesting a closer link between the two organelles. (more…)
