Hanging out in the kitchen? Chances are, you—and your smartphone—are within five metres of the refrigerator. Right now, two companies are planning for a future in which that means you could get the charge on your phone topped off.

How thin can an electrical generator possibly be? Thanks to a study published yesterday in Nature, the answer is about as thin as possible. Using molybdenum disulfide, researchers from the Georgia Institute of Technology and Columbia Engineering proved that a layer just an atom thick can generate an electric charge.

Virtually all homes point their solar panels south, where they can best capture rays from the sun when it rises in the southeast and sets in the southwest. That way, residents collect the most power possible throughout the day, which they can use in their own homes or sell to the grid (if they have any power leftover). But critics say the panels would actually do more good facing west, where they could capture sunlight during the midday and afternoon when energy is most needed.

Cryan's research, published today in Proceedings of the National Academy of Sciences, found that certain species of tree-roosting bats are more likely to be killed by wind turbines when the blades are moving at low speeds. By tracking the bats with thermal surveillance cameras, near-infrared video, acoustic detectors, and radar, the researchers discovered that bats tend to approach turbines from downwind, particularly when the turbines spin slowly relative to the wind speeds around them. This led researchers to theorize that the wind currents around slow moving turbines may resemble those created by trees, where the bats gather to roost and hunt insects.

You could call it a rainy-day fund. A team of MIT researchers has built an all-liquid battery prototype that's designed to store excess energy from solar and wind power plants. When the sun isn't shining, or the wind isn't blowing, future versions of this battery could release energy captured during more productive times into nations' power grids.

Wind turbines stand on horizons like strange colossuses. Their distinctive shape and great size make them hard to miss -- even by radar systems. The giants can obstruct signals, giving countries the uncomfortable choice of either not having radar somewhere or passing up on renewable energy. To bypass this issue, French turbine makers EDF Energies Nouvelles have developed new wind turbines that utilize stealth technology, to catch only wind, not radar signals.
