A new app teaching people about energy efficiency reflects how technology plays a key role in reaching new audiences

Marina Ollé Hurtado writes on the youris.com about a user-friendly smart app to help people improve their energy-saving behaviours developed by European researchers.     An intelligent app to teach people energy efficiency Energy demand is growing across many countries in the world as populations increase and people get richer. In fact, global energy consumption … Continue reading A new app teaching people about energy efficiency reflects how technology plays a key role in reaching new audiences

An alternative white paint for buildings containing barium sulphate could be more effective at reflecting the solar radiation than traditional gypsum paint

We are always interested in new innovations. Andrew Parnell, Research Fellow in Physics and Astronomy at the University of Sheffield discusses the impact of using an alternative white paint containing barium sulphate (BaSO₄) that could be even more effective at reflecting the solar radiation hitting buildings back into space. The article is on The Conversation … Continue reading An alternative white paint for buildings containing barium sulphate could be more effective at reflecting the solar radiation than traditional gypsum paint

Nasa is corralling companies to demonstrate improved ways to power aircraft via batteries rather than jet fuel

It is encouraging that the National Aeronautics and Space Administration (Nasa) in the US is organizing demonstration tests of electric propulsion. It turns out Nasa has been working on electric planes for the past decade and it is good to see the demonstrations now starting. Oliver Milman discusses latest developments in an article on the … Continue reading Nasa is corralling companies to demonstrate improved ways to power aircraft via batteries rather than jet fuel

It’s time for another generation of cooling equipment that is much gentler on the climate system

Scott Denning, Professor of Atmospheric Science at Colorado State University writes on The Conversation website about efforts in the US to eliminate hydrofluorocarbons used as coolants in refrigerators, air conditioners and heat pumps.   How cleaning up coolants can cool the climate – why HFCs are getting phased out from refrigerators and air conditioners The U.S. … Continue reading It’s time for another generation of cooling equipment that is much gentler on the climate system

Will vertical axis wind turbines replace traditional design?

Harry Cockburn asks in an article on the Independent website if we are about to see a revolution in turbine design.   ‘More efficient’ vertical turbines should replace traditional design on wind farms, researchers say Farm of Vertical Axis Wind Turbines (Oxford Brookes University) New research suggests the now-familiar sight of three-blade wind turbines should … Continue reading Will vertical axis wind turbines replace traditional design?

Novel energy storage technology involves suspending heavy weights above deep mine shafts

Under this novel system, weights are winched above mine shafts using green power generated on sunny or windy days, ready to be dropped to generate power when renewable output slumps or the grid needs power to “balance” its output.  Madeleine Cuff discusses the technology in an article on the inews website.   Mine shafts set … Continue reading Novel energy storage technology involves suspending heavy weights above deep mine shafts

‘Whitest ever’ paint reflects 98% of sunlight

Scientists in the US have developed a paint significantly "whiter than the whitest paint currently available". Tests carried out by researchers at Purdue University on their "ultra-white" paint showed it reflected more than 98% of sunlight. That suggests, the scientists say, that it could help save energy and fight climate change. Damian Carrington discusses the … Continue reading ‘Whitest ever’ paint reflects 98% of sunlight

In search of a more sustainable tire

The Russian dandelion helped supply the Allied forces with rubber through the Second World War. Now, tire makers are hoping it could make a commercial comeback to help tires become more sustainable. Jack McGovan explains in an artlcle on the Deutsche Welle website.   Could rubber from dandelions make tires more sustainable? In 1931, Soviet … Continue reading In search of a more sustainable tire

‘Skybrators’ can generate clean energy without environmental impact of large windfarms, says green start-up

Clean energy technologies are evolving and one company has pioneered a new approach to wind power by forgoing the need for turbine towers and blades.  Jillian Ambrose explains in an article on The Guardian website.   Good vibrations: bladeless turbines could bring wind power to your home The giant windfarms that line hills and coastlines … Continue reading ‘Skybrators’ can generate clean energy without environmental impact of large windfarms, says green start-up

Rethinking cement

The production of cement, the binding element in concrete, accounted for 7% of total global carbon dioxide emissions in 2018. Given the scale of the industry and its greenhouse gas emissions, technologies that can reinvent concrete could have profound impacts on climate change. At the University of Michigan, we are working on composites that produce … Continue reading Rethinking cement
