Wireless Electrical Transmission as the name shows is the Transmission of Electrical Energy without wires to any place on Earth. Even to the most remote areas.
The Electrical energy is first converted into Microwaves then beamed to a Geosynchronous satellite and Beamed back on Earth where needed and converted back to electrical energy. Where it can be used to power Electrical Equipments.
Wireless Power Transmission Experiments at Wardenclyffe.
In 1899 Nikola Tesla was able to light lamps over 25 miles away without using wires. Also the high frequency current of tesla coil, could light lamps filled with gas (like Neon).
1940s to Present
World war II developed ability to convert energy to microwave using magnetron but no method to convert microwave back to electricity.
In 1964 William. C Brown demonstrated a Rectenna which would convert Microwaves Power to Electricity.
Microwave Power Transmission And Reception Technique
Microwaves generated using the Magnetron from the base station can be received at any location on Earth with the help of Geosynchronous Receiving and Transmitting Satellites.Advantages of Low Orbit And Geosynchronous Satellites:* These satellites will use microwaves to beam power to the receiving station and mobile power receiving devices.* Since The low Orbit Microwave Beam Would spread less, the ground based Rectenna could be smaller.
Advantages of Using Microwaves for Wireless Electricity Transmission
High Efficiency Up to 85% .
Power Level is Well Below International safety standard.
Beam is far below the lethal levels of concentrations even for a prolonged exposure.
Frequency is up to 2.45 GHz of the Micro Beam.
Retro-directive Beam Control capability.
No Air Or water Pollution is Created.
During Generation power can be Beamed to the location Where it is needed.
We don’t have to invest in a large Electrical Grid.
If Microwave Beams Carrying power could be beamed uniformly over the earth they could power cell phones, but the antenna length should be 25-30 cm square.
More Reliable Than Ground Based Solar Power Generation.
More Reliable Than Wired Electricity Transmission.
In Order To Have Wireless Electricity Transmission To Become a Reality, Following Things Have To Happen.
