How Do Wind Turbines Work? | Department of Energy

A wind turbine turns wind energy into electricity using the aerodynamic force from the rotor blades, which work like an airplane wing or helicopter rotor blade. When wind flows across the blade, the air pressure on one side of the blade decreases. The difference in air pressure across the two sides of the blade creates both lift and drag.

ATP cycle and reaction coupling | Energy (article) | Khan Academy

All this really means is that an appreciable amount of energy is released when one of these bonds is broken in a hydrolysis (water-mediated breakdown) reaction. ATP is hydrolyzed to ADP in the following reaction: ATP + H 2 O ⇋ ADP + P i + energy. Note: P i just stands for an inorganic phosphate group (PO 4 3 −) .

Kinetic Movement: How Does A Kinetic Watch Work?

A kinetic watch works by transforming motion energy into stored energy. When you swing your arm, shake your hand, or move around, a rotating pendulum will move around inside the watch. This pendulum will then spin a pinion (up to 100.000 RPM), which in turn will cause a small electrical generator to charge an energy storage device (the ...

Understanding Mechanical Clocks

All mechanical clocks need energy to run, and energy is made through the act of winding. Winding your clock manipulates the internal mainspring to generate energy. When the mainspring slowly unwinds, it puts a series of parts in motion which results in the turning of the gears. Perhaps the most important component inside a mechanical clock is ...
