MECHANICAL ADVANTAGE AND SIMPLE MACHINES Science Clarified

MACHINES AND CLASSICAL MECHANICS. There are four known types of force in the universe: gravitational, electromagnetic, weak nuclear, and strong nuclear. This was the order in which the forces were identified, and the number of machines that use each force descends in the same order.

Energy conversion | technology | Britannica

Energy conversion: Energy conversion, the transformation of energy from forms provided by nature to forms that can be used by humans. Over the centuries a wide array of devices and systems has been developed for this purpose. Some of these energy converters are quite simple. The early windmills, for

Airborne wind turbine Wikipedia

An airborne wind turbine is a design concept for a wind turbine with a rotor supported in the air without a tower, thus benefiting from more mechanical and aerodynamic options, the higher velocity and persistence of wind at high altitudes, while avoiding the expense of tower construction, or the need for slip rings or yaw mechanism.An electrical generator may be on the ground or airborne.
