Finding green energy when the winds are calm and the skies are cloudy has been a challenge. Storing it in giant concrete blocks could be the answer.

The concrete blocks are slowly hoisted upwards by motors powered with electricity from the Swiss power grid. As each block descends, the motors that lift the blocks start spinning in reverse, generating electricity that courses through the thick cables running down the side of the crane and onto the power grid. In the 30 seconds during which the blocks are descending, each one generates about one megawatt of electricity: enough to power roughly 1,000 homes.

    It’s also kind of sad because you can tell that the Solar Roadways guys do actually believe in their concept (otherwise they’d have eloped with everyone’s money years ago)

    Why run away when you can just make more money continually while being an amateur?
