Simple, solar-powered water desalination

A completely passive solar-powered desalination system developed by researchers at MIT and in China could provide more than 1.5 gallons of fresh drinking water per hour for every square meter of solar collecting area. Such ...

Water out of thin air: California couple's device wins $1.5M

It started out modestly enough: David Hertz, having learned that under the right conditions you really can make your own water out of thin air, put a little contraption on the roof of his office and began cranking out free ...

Micro drilling turbines improve efficiency of geothermal systems

Geothermal systems are becoming an increasingly important source of clean and, above all, baseload-capable energy. But the wells, which can be several thousand meters deep, are risky, and things can sometimes go wrong. Fraunhofer ...

Robots collect underwater litter

Removing litter from oceans and seas is a costly and time-consuming process. As part of a European cooperative project, a team at the Technical University of Munich (TUM) is developing a robotic system that uses machine learning ...

A tiny soft robot that mimics jellyfish

A team of researchers at the Max Planck Institute for Intelligent Systems has developed a soft robot that effectively mimics a tiny jellyfish. In their paper published in the journal Nature Communications, the group describes ...

Solar-powered system offers a route to inexpensive desalination

An estimated two-thirds of humanity is affected by shortages of water, and many such areas in the developing world also face a lack of dependable electricity. Widespread research efforts have thus focused on ways to desalinate ...

An underwater navigation system powered by sound

GPS isn't waterproof. The navigation system depends on radio waves, which break down rapidly in liquids, including seawater. To track undersea objects like drones or whales, researchers rely on acoustic signaling. But devices ...
