Hybrid Muscle was both a work and exhibition space, built in Chiang Maï in Thaïland, that would generate its own electricity and thus be "unplugged" from the power grid.
The engine was driven by the muscle power of an albino Buffalo. The buffalo worked a few hours a day to lift a steel counterweight. Once freed the buffalo would lounge around the rice field and the mechanical energy stored was turned into electrical energy to power ten light bulbs, laptops, mobile phones.
