Viaducts with wind turbines, the new renewable energy source

Wind turbines could be installed under some of the biggest bridges on the road network to produce electricity. So it is confirmed by calculations carried out by a European researchers team, that have taken a viaduct in the Canary Islands as a reference. This concept could be applied in heavily built-up territories or natural areas with new constructions limitations.

Vegetarian and ‘healthy’ diets could be more harmful to the environment, researchers say

Following the USDA recommendations to consume more fruits, vegetables, dairy and seafood is more harmful to the environment because those foods have relatively high resource uses and greenhouse gas emissions per calorie, say researchers. A new study measured the changes in energy use, blue water footprint and GHG emissions associated with US food consumption patterns.

Sponge-like material to more efficiently store natural gas

Researchers are utilizing metal-organic frameworks (MOFs) to develop a new type of storage system that would adsorb natural gas like a sponge and allow for more energy-efficient storage and use.

On soft ground? Tread lightly to stay fast

Soft steps and large feet can allow animals and robots to maintain high speeds on very loose soil and sand. These findings offer a new insight into how animals respond to different terrain, and how robots can learn from them.

Silver: The promising electrode winner for low-cost perovskite solar cells

Researchers have identified a contributing factor to short lifetime in perovskite solar cells with silver electrodes. Currently, the most common electrode material in perovskite solar cells is gold, which is extremely expensive. The low-cost alternative to gold is silver, around 65 times cheaper.

Horse racing position cuts drag up to 66 per cent

Researchers have revealed precisely how much different slipstreaming tactics reduce drag on a horse during a race.  

New plastic solar cell minimizes loss of photon energy

Scientists demonstrate an unconventional means to achieve more efficient and robust conversion of solar energy into electricity.
