  • Spherical energy converter
    Patent number: 10914173
    Abstract: The invention relates to a spherical working chamber and to two flat rotary pistons as internally turning, rotating pistons that are used to produce energy, which flat rotary pistons are driven by means of a descent of creeks, rivers or gray water and rainwater from high-rise buildings. Because of the even rotation of the output shaft of the flange-mounted transmission, an electrical generator can be connected. The energy converter plus generator can also be used as a mobile unit in emergency situations at waterfalls in order to generate electricity.
