Energy Conversion Physics
This page will cover the basic physics of energy conversion covering a fairly wide scale of phenomena and devices.
Mechanical Energy Conversion
The photoelectric effect was actually discovered by Einstein and it is for which he won the Nobel Prize in physics in 1921.
In the piezoelectric effect when stress is applied to a material it results in a build up of charge. The effect is reversible. This is the basis for the functioning of microphones as they convert the pressure waves of sound waves into pulse of charge which are detected by a receiver and amplified.
Piezo Electric Crystals
The thermoelectric effect also known as the Seebeck or Peltier effect is the phonemena whereby when two different types of metals are joined together and one end is held at a higher temperature and the other at a lower, will result in a voltage differential and when linked up in a circuit will produce some current flow.
Thermal Chemical Energy Conversion
Oxidation or Burning
This covers all the known fuels such as oils and gases.
