Move aside energy efficient LEDs. We’ve just stumbled across lighting fixtures that don’t really need grid connections whatsoever! Instead, these lights use bacteria to light up! Dutch electronic bigshot Philips has come up with the Bio-Light concept, a lighting solution that pretty much makes LEDs and CFL lights look silly and insignificant! Part of Philips’ Microbial Home concept, the Bio-Light concept uses waste to generate energy for itself and light up. Made from hand-blown glass cells containing a type of bacteria that generate light through a chemical process called luminescence , this could indeed be the lighting solution of the future!
