Could New Wireless Power Transfer Unleash Electric Medicine?

Stanford University engineers say they have figured out a way to wirelessly send electric power deeper into the body than ever before.

Inventor and electrical engineering assistant professor Ada Poon created a near-field power transmitter like those used to recharge wireless toothbrushes in their cradle. The difference is that hers uses tissue between the transmitter and medical device implanted in the body to amplify the electromagnetic waves. Her team then created an electrode and receiver unit about the size of a grain of rice that can be placed wherever electrical stimulation is required.

tech alternative_energy wind_turbines innovation electricity renewable_energy power design

At first glance, this might look like a crew constructing your standard high-tech wind turbine. But the machine is actually perching atop a new “space-frame” tower instead of the traditional metal tube. The new design involves a metal latticework jacketed in fiberglass that can be transported in pieces in shipping containers and regular trucks.

This innovation, made by GE’s wind power unit, opens up new areas to erect taller wind generators that were previously inaccessible because of transportation issues. The prototype above is being installed at a California wind farm. 

The tower isn’t the only thing that’s new, though. The rotor on top that spans 400 feet in diameter is spinning a 1.7-megawatt turbine.

Spore Power: Wetting Bacteria Makes Electricity And Robot Muscles

by Petti Fong

If dry bacteria spores of the genus Bacillus were boxers, commentators would say they punch above their weight.

When they dehydrate, the rod-shaped spores— dormant cells that help the microorganism survive tough environmental conditions and are naturally found in soil and vegetation—shrivel or curl like a leaf. Add some moisture and they straighten out again. Studies have shown that they can absorb water and expand with remarkable force. Now scientists say this phenomenon can be harnessed to use the microbes as a potential source of renewable energy or as muscles to make superstrong robots.

In research recently reported in the journal Nature Nanotechnology, a team detailed how they smeared spores on a flat piece of rubber and created a bacteria-powered generator.
