Answer to renewable energy lies in the art of croissant making

Sustainability is today's demand and there is no doubt in that. In a new study, researchers took inspiration from the art of croissant-making to find a possible solution for the sustainable energy problem.A kind of bread, the croissant is made by pressing and folding the dough to create a layered pastry.And researchers applied this same technique to a dialectic capacitor, a device that stores energy like a battery.By pressing and folding a polymer film capacitor - a capacitor with an insulating plastic film - they were able to store 30 times more energy than the best-performing commercially available dielectric capacitor, biaxially oriented polypropylene (BOPP).The findings were published in the journal Nature Communications and showed that this is the highest energy density ever reported in a polymer film capacitor.Renewable and sustainable energy sources like solar and wind are intermittent by nature and to make them of wider practical use it is necessary to develop efficient, ...
