  • Witricity: Wireless electricity…it’s possible

    This diagram shows how the magnetic field can wrap around a conductive obstacle.

    We’ve always all dreamt about wireless energy. The world is that why we want everything to be wireless. No cable and less infrastructure. Imagine a house with one simple generator that powers every single device without any cable. You wouldn’t even have to think to charge your phone, it will simply charge from your pocket as soon [...]

  • Algae Fuel

    By definition, oil is a limited commodity. This is the reason why people start working on electric cars for example, which are presented as being the ultimate solution to our problem.

  • Solar desalination

    There are so many places where fresh water is an issue. And in most of them, sun is not. Since those places often have access to the sea too, water desalinization could change everything. Imagine what would australia or israel be if they could produce as much fresh water as they like just with the energy of the [...]
