Magnets are being used to extract algal molecules for the beauty, bioplastics industries

Entrepreneurs in the aquaculture sector face a problem – extracting all the valuable molecules from seaweed and algal cells is still really difficult. But marine enzymes and magnets are now making it easier to remove precious molecules and can even turn microalgae into magnetically-guided ‘vehicles’ for targeted drug delivery. Algal cells contain all kinds of … Read more

Managing energy demand spikes with seasonal forecasts of heatwaves and cold spells

Researchers want to make climate forecasts more accessible to help the energy and other industries better predict spikes in usage.

The impact of heavy droughts, heatwaves and cold spells on energy demand and supplies would be lessened with seasonal climate forecasts that allow energy companies to better predict spikes in usage ahead of time, researchers say. Researchers already have the ability to predict what changes in climate can be expected in two to three weeks’ … Read more

Flat-pack homes and profit-sharing retrofits are making sustainable housing affordable

Solar panels help the SOLACE flat-pack houses produce more energy than needed.

Wealth-generating, flat-pack solar houses and a profit-sharing scheme that incentivises retrofitting are bringing sustainable living to people who would otherwise not be able to afford it. ‘One of the biggest problems that we see right now is (the creation of) a big gap between the lower and the middle classes. Everyone is talking about this … Read more

Hydrogen-powered boat plots course for the future of ocean travel

Every year, the technologies used to power the Energy Observer in its six-year round-the-world journey are being improved.

The first day that Jérôme Delafosse stepped aboard the Energy Observer, an experimental catamaran run on hydrogen, he knew the plan of sailing around the world on clean energy was a realistic one, he says. Now, the explorer and documentary maker is one year into a six-year odyssey around the globe with his friend Victorien Erussard, an … Read more
