Thermoelectric coolers are solid state heat pumps used in applications wheretemperature stabilization, temperature cycling, or cooling below ambient arerequired.
Electric Cooler
Tesla Coil
A Tesla coil is a radio frequency oscillator that drives an air-core double-tuned resonant transformer to produce high voltages at low currents.
Piezo Electricity
Piezoelectricity is the electric charge that accumulates in certain solid materials in response to applied mechanical stress.
Dynamo
A dynamo is an electrical generator that produces direct current with the use of a commutator
Newton's Cradle
A Newton's cradle is a device that demonstrates conservation of momentum and energy using a series of swinging spheres.
Eddy Current Brake
An eddy current brake, like a conventional friction brake, is a device used to slow or stop a moving object by dissipating its kinetic energy as heat.
Electricity generation through speed breaker
Energy wasted at speed breakers through friction can be used to store and generate electricity using a simple mechanism.
Sound Energy
Noise (sound) energy can be converted into viable source of electric power by using a suitable transducer.
