Designer and inventor extraordinaire Knut Karlsen recently unveiled an inspired approach to portable power that can’t be beat for its elegant simplicity: a prototype battery capable of charging itself when exposed to sunshine. His slick set of SunCat C-cells are wrapped in flexible photovoltaic panels and will slowly recharge when left to bask in the sun – just like a cat.
Rechargeable batteries are a boon to eco-enthusiasts who use portable electronics, however all too often they require additional peripherals in order to keep them charged. These devices generally take the form of a black box loaded with non-biodegradable plastics and heavy metals – not very earth-friendly.
