From Ars Technica: Getting ready for the end of growth on Earth


Long Beach, California—Paul Gilding wants to scare us. He wants to scare us into acting before it’s too late. “The Earth is Full. Full of us, full of our stuff. Full of our waste,” he said during his TED talk. In financial terms, we live on the Earth like we are spending 50 percent more than we earn.

Gilding has been agitating for sustainability long before most people became aware of the concept, and he has a bleak message for the prospects of the free market. Our economy is not sustainable, and woefully unprepared for hitting the Earth’s limits. It’s not just a little bit over the limits of sustainability, either—we are way beyond that.

From Popular Science – New Technology, Science News, The Future Now: Thermoelectric “Power Felt” Fabric Lets You Sit on Your Phone to Power It

Power Felt Wake Forest University

A team from Wake Forest University’s Center for Nanotechnology and Molecular Materials has created a new thermoelectric fabric they call Power Felt. It’s constructed of “tiny carbon nanotubes locked up in flexible plastic fibers,” though the final product looks and feels like fabric, and creates and electrical charge from changes in temperature–like, say, touching it with your hot finger, or sitting on it with your hot butt (hot in this case referring to temperature and thus wholly inoffensive science).

Thermoelectrics isn’t a new field, but it’s mostly been hampered by expensive materials that can cost up to $1,000 per kilogram. But Corey Hewitt, a graduate student at Wake Forest and member of the Power Felt team, says the new design could drastically bring down the price. For something small, like a cellphone case, the addition of Power Felt could cost as little as a dollar extra. And there are all kinds of possible applications, from apparel to car seats.
