Imagine a lamp. Any lamp. Now imagine having to water it.
Dutch product designer Ermi van Oers created Living Light: plants that double as lights. Or lights that double as plants ? whichever way you prefer looking at it. The lights run on electricity generated by bacteria in the soil.
Healthier plants produce more energy. If you take care of it properly, the Living Light will produce up to 0.1 mW. Enough to use it as a night lamp, but not sufficient to properly light a room.
Imagine if we could use boulevard trees for powering street lights?
