HandEnergy is a generator of endless energy. Produce, accumulate and use! HandEnergy is your personal generator of endless energy. It means that you can produce it everywhere you want. HandEnergy is compact and easy device. Produce, accumulate and use! Principle of work is based on properties of a two-axis rotor gyroscope. Unlike a gyro, the end points of the axis of a HandEnergy are located in a circular slot. You start by spinning the ball, then rotate the HandEnergy enclosure around. This forces the side of the end of each axis against the sides circular slot, and combined with the resistance to having the axis rotated creates enough “downforce” combined enough friction to create enough grip to increase the rate of rotation of the interior ball.
