The biggest solar exhibit at the EXPO 2000.
Eighteen 10m solar lights were constructed to gently sway with the wind. At dawn, each strand of SolarGrass was illuminated by a hundred LEDs with power gathered by the round solar panel above.
Seventeen individually shaped, free-floating solar panels powered integrated water-jets that varied their fountain height depending on the strength of the sun.
A playful illustration of the power created at each moment.
