Any heat engine
converts thermal energy (heat) into
mechanical energy (
motion).
Chemist John Pojman of Louisiana State University in Baton Rouge adds that such roving droplets «might be useful as a pumping mechanism for microfluidics,
converting chemical energy to
mechanical motion in small devices,» such as the microfluidic labs - on - a-chip many researchers are developing as diagnostic machines.
That process worked with a finger swipe or a light pressing
motion to activate the devices —
converting mechanical energy to electrical energy.
The team calculated that most of the sonic energy is
converted into
mechanical energy, which creates
motion in the liquid surrounding the bubble.
«We confirmed that if the
mechanical energy is entirely
converted into electrical energy, the energy generated by the daily
motion of an arm can sufficiently cover the energy consumption of a smart watch and even the stand - by energy consumption of a smart phone.»
To make the discovery, the researchers tapped into a concept called photostriction — where light is
converted into
mechanical motion.
motor A device that
converts electricity into
mechanical motion.
Mechanical link between the piston and the crankshaft that enables the piston's up - and - down travel to be
converted into the crankshaft's rotational
motion
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.
Wind energy: Kinetic energy present in wind
motion that can be
converted to
mechanical energy for driving pumps, mills, and electric power generators.
JB - your argument that energy added to a free body spinning is only correct if that heat energy can be
converted to
mechanical motion to aid the spinning.
However, while equilibrium thermodynamics allow the estimation of the maximum possible
mechanical work from heat it provides neither information about the actual efficiency of
converting heat to work (kinetic energy) nor whether such conversion to
motion actually occurs.
