Such Pretty Moonstones

I’m in love with the Seoul Green Project called Luna Piedra which means moonstone in Spanish. These beautiful pebbles illuminate with embedded OLEDs. They replace traditional lighting setups which aren’t portable and waste a lot of energy. The Luna Piedra generates enough power by water currents using a very tiny nano generator. It doesn’t heat up and leaves no polluting effluents. I want one, NOW.

    Really like these moonstones.
    By the way it’s ‘polluting effluent’ not affluents (someone who is affluent is well-off or rich)

    Good job. The moonstones look really nice in that brook.

    what happens when it gets clogged by debris? i don’t really see this thing in rivers…

    • Craig says:

      Good point about the debris, few rivers around here could support these I think without clogging them up.

      They are quite lovely though and would be great in some artificial waterways/installations where debris isn’t as much an issue.
