Power generation using railway track

17 May

The key element of an electrostatic railway track power generator is a variable capacitor, which can convert mechanical energy into electrical energy by means of the work done by an external force against the electric field formed between the two plates of the capacitor

A variable capacitor is a capacitor whose capacitance may be intentionally and repeatedly changed mechanically or electronically. Variable capacitors are often used in L/C circuits to set the resonance frequency, e.g. to tune a radio.

Concept :

Power generation is achieved in this device by pulling apart the base plate and the movable plate and then extracting energy stored in the electric field. During the input phase, the mass is forced against the contact studs(power supply) on the base plate, connecting it to a charging circuit, which brings it to a starting potential. In response to motion of the frame, which is attached to the host, the mass is accelerated sufficiently in the opposite direction and moved to the top plate where it will be stopped by the contact studs on the top plate. The energy stored in the capacitor is then extracted by an output circuit.

How this system works with rails?

An electrical power generation system comprises a variable capacitor and a power source. The electrical power generation system is configured to generate electric power via movements of the rail. The power source is used in the form of a generator to prime the variable capacitor that effectively multiplies the priming energy of the power source by extracting energy from the passing vehicle. By alternately priming the variable capacitor using charge from the power source and discharging it at a later time in a cyclic manner to change the capacitance, a significantly large amount of electrical energy is produced due to change in capacitance than from the power source itself.

The system includes a power source, such as a power generation device or an external powersource. The power train power generation system includes first and second electrical capacitance portions that are electrically coupled to the power source and that are configured to carry positive and negative charges, respectively. This system further includes a biasing device that is configured to separate the first and second capacitance portions with respect to one another. Thus, by varying the distance between the capacitance portions in response to a vehicle on the rail, the capacitance portions cooperate to act as a variable capacitor that facilitates the co-generation of power with respect to the system. That is to say, the mechanical energy of the biasing device is converted into electrical energy for the system.

Another Way ?

There is one other way of generating electricity using trains is to use T Box wind power generator, which use the wind produce by trains to produce power.
