Charge your phone with a Plant
Barcelona based company Arkyne Technologies have taken renewable energy to a new level: the soil and roots of a plant. They came up with a way of charging your phone via plant photosynthesis. The leaves are used like solar panels where sunshine turns carbon dioxide and water into oxygen and organic compounds. Then, there are microorganisms (or bacteria) inside the pot that break down the compounds into electrons.
All you have to do is plug your device into the undercover pebble designed USB port and charge up. It can provide up to 3 full charges a day.
The product is called Bioo Lite and is expected to be launched in December. Get ready Santa!
