Relying on evaporation and radiation – but not electricity – the system could keep food fresh longer or supplement air conditioning in buildings.

Researchers are controlling pore openings for maximum molecule capture.

A team of architectural and building systems engineers used energy models that simulate heat transfer and air conditioning system performance to tackle this perennial question: will you need to remove more heat from your home by continuously removing heat throughout the day or removing excess heat only at the end of the day?

Extreme weather events are becoming more frequent and intense, sometimes with tragic consequences. Europe's coastal cities are preparing to meet the challenges with help from nature and data from outer space. For example, one project – to bio-engineer sand dunes in Sligo for stronger natural defences – is also being tested in Portugal.

Hydrogen is carving out its place in the world of renewable energy. Regional developments like hydrogen valleys and hydrogen islands are serving as blueprints for larger ecosystems to produce and consume this versatile fuel locally. 

The UK government has recently announced new grants to encourage the public to move from gas boilers to heat pumps, a greener energy alternative. But little has been said about electric boilers as another low-carbon option, writes Jovana Radulovic, senior lecturer, School of Engineering, University of Portsmouth.
