Korean Designer Yichun Chuang has successfully made some beautiful pebbles, dubbed as Luna Piedra, harness the power of water currents at the Seoul Green Project. Having embedded OLEDs, the pebbles shine with a definitive grace as a very tiny nano generator keeps on powering them all the time capably.
Since these water-resistant nuggets are immersed in water continually, the moonstones (Luna Piedra is moonstone when translated into Spanish) do not heat up and never explode suddenly. Offered in varied shapes, these can beautify the artificial waterways or similar installations.
