Researchers at North Carolina State University in the US have developed a new dynamic window material that can tune out certain wavelengths of light and block heat to suit the conditions. Three Modes Now Possible The Dynamic window glass can be used to switch windows between three modes: transparent, or “normal” windows, windows that block infrared light (helping to…
FlyZero’s and UK Aerospace Technology Institute’s (ATI) study has concluded that green liquid hydrogen powered aircraft could deliver the net-zero 2050 target for aviation. Two Technologies The 12-month study results suggests that aviation can achieve net-zero by 2050 through the development of both sustainable aviation fuel (SAF) and green liquid hydrogen technologies. What Is Green Liquid Hydrogen? Liquid hydrogen…
With sustainability credentials ever more important to stakeholders, we look at how IT buyers can ensure that the green claims made by those in their supply chain can be trusted. The Greenwashing Challenge One of the main challenges buyers face is ‘greenwashing’ whereby supply chain companies may create a false impression about how sustainable they are in order to…
Glasgow arts venue SWG3’s innovative new heating and cooling system uses the capture the body heat emitted from its victors to provide a renewable energy source. The BODYHEAT System As part of its drive to become a net zero venue, the first of its kind BODYHEAT system took 3 years to develop. The system is now active across the…
The development of a battery-free, wireless underwater camera by MIT engineers could help to build more accurate climate models and help scientists to better understand how climate change impacts the underwater world. Challenges A massive 95 percent of Earth’s oceans never been observed, meaning that we have seen less of the ocean than we have the far side of…
Finnish engineers, Markku Ylönen and Tommi Eronen have made a giant battery which stores heat from green energy in sand that can be used as an all-year-round energy supply. Sand Battery The Finnish engineers’ company, Polar Night Energy, has made a sand battery in Kankaanpää, in the west of Finland. The battery consists of large silo which has been…
Researchers at the University of Tokyo have developed a device that can desalinate water at least one thousand times faster than existing methods. A Membrane Made From Tiny Fluorine-Based Nanoscopic Rings Scientists at the Tokyo School of Engineering’s Department of Chemistry and Biotechnology constructed tiny fluorine-based nanoscopic rings that were coated with a hydrophobic surface of a dense molecular…
With container ships being bigger greenhouse gas producers that aeroplanes, London-based company ‘Seabound’ has developed technology that reduces up to 95 per cent of CO2 emissions per ship. The Problem The shipping industry is responsible for producing around 940 million tonnes of CO2 annually, which equates to at least 2.5 per cent of the world’s total CO2 emissions. This is…
A fast-growing Amsterdam-based start-up, The Great Bubble Barrier, as the name suggests has created a barrier that used bubbles to stop plastic waste from entering and to remove plastic from waterways. Most Plastic Travels Via Rivers And Canals Each year, up to 80 per cent of the 8 million tons of plastic reaching the ocean first flow along rivers…
With our devices using lithium-ion batteries and with Electronic Vehicles (EVs) currently dependent on lithium for their rechargeable batteries we look at the environmental impact of lithium mining, and what the possible alternatives could be. Lithium Lithium is a naturally occurring element found ionic minerals like petalite, lepidolite, and spodumene, and is a soft, silvery-white alkali metal sometimes referred to…
