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

Daimler, the world’s largest maker of heavy trucks, aims to build hydrogen-fuel trucks

Electric cars get all the attention, but truckmakers are also under pressure to shift from fossil fuels to electricity. Jack Ewing discusses in an article on the New York Times website what Daimler is up to.   World’s Largest Long-Haul Truckmaker Sees Hydrogen-Fueled Future Carmakers have been promising to scrap the internal combustion engine, and … Continue reading Daimler, the world’s largest maker of heavy trucks, aims to build hydrogen-fuel trucks

Our society has come to believe that technology is the solution to our climate crisis – it isn’t

With the climate crisis, Peter Sutoris argus this moment calls for humility – we cannot innovate ourselves out of this mess. The problem with believing technology is the solution is that it focuses on the symptoms, not the causes of environmental decay.  Peter Sutoris, is an anthropologist of development and the environment, and the author … Continue reading Our society has come to believe that technology is the solution to our climate crisis – it isn’t

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

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

Is new fast-charging battery a gamechanger?

With the increased attention to switch to electric vehicles, one of the weak points concerns batteries. One Israeli company has come up with a battery that can be fully charged in just five minutes. While five-minute charging is not a complete gamechanger, it makes the transition to electric vehicles an easier sell, according to an … Continue reading Is new fast-charging battery a gamechanger?
