2. Regenerative braking - Wikipedia

   en.wikipedia.org/wiki/Regenerative_braking

   Regenerative braking is a two-step process involving the motor/generator and the battery. The initial kinetic energy is transformed into electrical energy by the generator and is then converted into chemical energy by the battery. This process is less efficient than the flywheel.

3. Thermoelectric generator - Wikipedia

   en.wikipedia.org/wiki/Thermoelectric_generator

   A thermoelectric generator ( TEG ), also called a Seebeck generator, is a solid state device that converts heat (driven by temperature differences) directly into electrical energy through a phenomenon called the Seebeck effect [ 1] (a form of thermoelectric effect ). Thermoelectric generators function like heat engines, but are less bulky and ...

4. Newman's energy machine - Wikipedia

   en.wikipedia.org/wiki/Newman's_energy_machine

   Newman's energy machine. Newman's Energy Machine was a DC motor which the inventor, Joseph Newman, claimed to produce mechanical power exceeding the electrical power being supplied to it. In 1979, Newman attempted to patent the device, but it was rejected by the United States Patent Office as being a perpetual motion machine. [ 1]

   Image Credits: H3x. It’s plain to see that electric vehicles are the future, but there’s more to making that change happen than swapping out a gas motor for a battery-powered one ...

6. Motor–generator - Wikipedia

   en.wikipedia.org/wiki/Motor–generator

   A motor–generator (an M–G set) is a device for converting electrical power to another form. Motor–generator sets are used to convert frequency, voltage, or phase of power. They may also be used to isolate electrical loads from the electrical power supply line. Large motor–generators were widely used to convert industrial amounts of ...
