perpetual motion machine

Permanent Motive Machine 0.9 × 0.5 × 1.5m Bracket: The overall sheet metal surface is sprayed with plastic, with a plate thickness of 1.5mm. Display Accessories: Rotary Table, Iron Ball, Rotating Structure, etc. Rotary Table Material: Aluminum Alloy Material, Wire Cutting; Ground connection: fixed with expansion bolts; A perpetual motion machine is a type of mechanical device that can continuously move and perform external work without the need for external input of energy, energy, or with only one heat source. A machine that does not consume energy but can always perform external work violates the law of conservation of energy, hence it is called the "first type of perpetual motion machine". A machine that continuously absorbs heat from seawater or air in nature and converts it into mechanical energy without a temperature difference, violates the second law of thermodynamics, and is therefore called a "second type perpetual motion machine". These two types of perpetual motion machines are concepts that violate current objective scientific laws and cannot be manufactured.
