mechanical energy

By 2021, the lab had set the machine on its quest to make a shape that absorbs the most energy, a property known as its mechanical energy absorption efficiency.

Placing both devices on a benchtop rocker moved water back and forth within the tubes and generated electrical currents by converting mechanical energy -- the friction from water hitting or sliding against the electrodes -- into electricity.

"I began to contemplate whether we could convert the evaporation energy into mechanical energy first, and then translate it into electricity," said Wu.

The fourth movement had a mahogany tone of divided cellos and a finale of mechanical energy and busy tinkering before a thrilling final flourish.

Based on the change in the volume of wax in response to temperatures it is exposed to, a wax motor creates pressure that moves mechanical parts, translating thermal energy into mechanical energy.
