Contained within a sealed unit, a WITT uses two pendulums connected to a flywheel to generate electricity. Movement causes the pendulums to swing, and they are attached to a shaft that then turns a flywheel in one direction. The flywheel is connected to a generator, which produces electricity. The unit harvests chaotic motion, fast, slow or erratic, turning it into useable power. The company claims that no other device captures energy from all six degrees of motion. Where most energy harvesting devices are point absorbers, taking up-and-down or side-to-side motion and turning it into useable power, the WITT takes all motion.
