Daily reports on the European and Global energy transition
Capacitors work like batteries. They store and discharge electricity. David Chandler at MIT explains how researchers there have designed a supercapacitor from concrete and carbon black, two cheap and common materials. The beauty of the idea is that they can be incorporated into building foundations, thus installing a battery virtually for free. A concrete capacitor cube 3.5m wide can store 10kwh, enough for a household. Similarly, concrete … [Read more...] Supercapacitor Diagram
