ESA's solar-powered giant one year on

ESA's 35-metre antenna in Australia has now been powered by the sun for over a year, cutting costs and reducing carbon emissions by 330 tonnes—equivalent to 1.9 million km driven by car.

How climate impacts solar and wind power supply

One of the challenges with solar and wind power is that, on any given day, the sun isn't always shining, and the wind isn't always blowing when we want it to. Now, zooming out, researchers at Columbia's Earth Institute have ...

Aluminum nitride to extend life of solar power plants

NUST MISIS scientists together with their colleagues from the Central Metallurgical R&D Institute (Cairo, Egypt) have developed a composite material to extend the life of solar towers up to five years. The research article ...

Colloidal quantum dots make LEDs shine bright in the infrared

The ideal optoelectronic semiconductor material would be a strong light emitter and an efficient charge conductor to allow for electrical injection in devices. These two conditions, when met, can lead to highly efficient ...

InSight is catching rays on Mars

NASA's InSight has sent signals to Earth indicating that its solar panels are open and collecting sunlight on the Martian surface. NASA's Mars Odyssey orbiter relayed the signals, which were received on Earth at about 5:30 ...

Ion drive space engine used on aircraft for first time

Imagine an aircraft engine that has no moving parts, produces no harmful exhaust and makes no noise. That's what researchers at the Massachusetts Institute of Technology (MIT) in the US have created by adapting a technology ...
