However, this light energy is not totally dissipated: it is
turned into mechanical energy through the twisting of the polymer chains, and stored in the gel.
For example, we can use biomass as a backup power source for mechanical energy production, something pre-industrial millers could not do — before the arrival of the steam engine, there was no way of converting
biomass into mechanical energy.
In both cases, an electric motor, which converts
current into mechanical energy, briefly reverses its function to become a generator, converting mechanical energy into current.
Xiaomi says they used a piezoelectric ceramic driver, which basically converts electrical
signals into mechanical energy and eliminate the need for an earpiece.
Any heat engine converts thermal energy (heat)
into mechanical energy (motion).
Big animals have longer legs or flippers to get from point A to point B. And bigger bodies have higher metabolic rates and more fast - twitch muscle cells, needed to convert chemical energy
into mechanical energy and rapidly accelerate.
Wind turbines convert the kinetic energy in the wind (the energy the wind has due to its motion)
into mechanical energy — the wind turns the blades of the wind turbine, and the blades turn a shaft inside the turbine.
As the blades of a wind turbine turn, the kinetic energy of the wind is converted
into mechanical energy, which is transmitted through a drive shaft to an electrical generator in the nacelle.
A wind turbine is a device that converts kinetic energy from the wind (also called wind energy)
into mechanical energy.
Guest essay by Jan Kjetil Andersen As Willis describes in his article on December 21, the atmosphere can be seen as a gigantic heat engine, i.e. a machine which convert thermal energy, namely temperature,
into mechanical energy, namely wind.
If even a very small fraction of the total energy stored in the latent heat of water vapor or from the heat of tropical ocean waters could be captured and converted
into mechanical energy, we would be able to meet a large portion of our present and future energy needs.
