Much of the power generated is wasted during transmission from power plant generators to the consumer.This
article introduces :
i) The most popular concept
known as Tesla Theory,
ii) The microwave power transmission (MPT) called Solar power satellite, and
iii) The highly efficient fibre lasers for wireless power transmission.
The transmission of power without wires may be a noble alternative for electricity transmission.
THE TECHNOLOGIES AVAILABLE
The famous Wardenclyffe Tower (Tesla Tower) was
designed and constructed mainly for wireless transmission of
electrical power. Wardenclyffe would permit wireless
transmission and reception across large distances with
negligible losses according to tesla theory. The modern ideas include microwave power transmission (MPT) called Solar power satellite to be built in high earth orbit to collect sunlight and convert that energy into microwaves, then beamed to a very large antenna on earth, the microwaves would be converted into
conventional electrical power.The primary components include a microwave source, a transmitting antenna, and a receiving rectenna.microwave source is a microwave oven magnetron with electronics to control the output power.output of the microwave source connected to a coax-to-waveguide adapter by a coaxial cable.A rectifying antenna called a rectenna receives the
transmitted power and converts the microwave power to DC.
With the use of "high-potential magnifying
transmitter,we can transmit distribute power from a central plant in
unlimited amounts, with a loss not exceeding a small fraction
of one per cent.
The main theories of the past were:
1. Transmission through or along the Earth,
2. Propagation as a result of terrestrial resonances,
3. Coupling to the ionosphere using propagation through
electrified gases
Transmission through or along the Earth:
electrical energy can be
propagated around the world between the surface of the Earth
and the ionosphere at extreme low frequencies in what is
known as the Schumann Cavity. We can resonate and deliver power
via the Schumann Cavity to any point on Earth.
fibre lasers
This method is similar to similar to microwaves concept but lasers emit energy at
frequencies much higher that microwaves.
using directional ultrasound
Here, transmitting device has a set of
ultrasound transducers forming an ultrasound transducer
array and a recieving device recieves the power.
Merits
-eliminate the cables, towers, and substations
-reduce the cost of electrical energy used by the
consumer
-remote ares unconnected by the power cables will be benefited.
-no
transmission and distribution loss.
-High Transmission Integrity and Low Loss. The efficiency of the
transmission can be as high as 96 or 97 per cent.
demerits
-Biological impact: its possible biological
effects were criticised. Calculating the circulating reactive power, it was
found that the frequency is very small and biologically compatible.
-Economic Impact:The concept looks to be costly initially. Only private, dispersed receiving stations will be
needed.a single resonant energy
receiver is required, which may eventually be built into
appliances.
