MIT scientists have discovered a way to get an electric current out of water droplets. Enough power to charge mobile phones can be drawn from water condensing and jumping from a super-hydrophobic surface.
Researchers from Massachusetts Institute of Technology (MIT) have come up with a simple device that – not without some improvements – could power electronic devices with ‘green’ energy.
The study by postdoctoral scholar Nenad Miljkovic, Associate Professor of Mechanical Engineering Evelyn Wang, and two others was published online in the journal Applied Physics Letters.
