Wireless electric transmission technology is about to come true

Since a switch engineer at the Pearl Power Plant in the center of Manhattan in 1882, electricity transmission around the world has traveled from point A to point B by the power line. Regardless of whether it is a high voltage transmission line or low voltage distribution line, all networks use wires. However, columns and power lines are not always suitable in all situations. It is possible to cost the transmission line or fiber optic cable to a remote island too expensive. Especially, for space applications, running wires from satellite collection to solar energy to the power plant on the ground is not easy. More and more electrical industries are increasing to reduce carbon emissions, the ability to transmit electricity at any time and come anywhere but regardless of the electric wire is becoming increasingly important, according to Popular Mechanics.

For more than a century, scientists and engineers discover a different method to transmit energy not through the wire, called beam energy transmission. For decades, investors, scientists and engineers seek to turn this technology into reality. They tested using microwaves, radio waves, even lasers to bring energy from one place to another.

Rick Hodgson, business development manager at Emerd beam energy transmission company in New Zealand, acknowledged the cutting of fossil fuel use as another main reason leading to wireless electricity transmission was seriously considered. The current challenge is the vehicle to charge. With beam energy transmission, electric trucks used in mining, drones and satellites can continue to operate while charging continuously. Emrod is the first company in the world to develop and introduce high power wireless electricity technology over a long distance. Their technology operates through the use of electromagnetic waves to transfer safety wireless and energy efficiency over a long distance.

All new technologies are competitive, but beam energy transmits are different. Part of the reason is that many wavelengths along the electromagnetic spectrum can be useful with beam energy transmission. Similar to any other energy source, limited to the use of this technology. For example, the EMROD system converts a direct direct electricity into a microwave and transmitted in the standards between the transmission and receiving antenna. Finally, it converts the beam of energy into one -dimensional electricity that can be used. Most beam energy transmission mechanism works in the same way, the difference lies in the specific wavelength transmission between the two antennas.

The microwave can be transmitted through the atmosphere and does not lose much energy, according to Sweeney. When transmitting microwave beams from relatively small distance such as automatic factory or to the remote island, the antenna may be quite small. But applying the same thing with satellites collecting solar energy in space will require a large number of square kilometers. In contrast, the laser system is easily affected by disturbance in the environment, but because their wavelength is in the micromet strip instead of centimeters like microwaves, experts can focus more beams, thereby using small receiving equipment a few dozen meters if transmitted from the space.

Beam energy transmission is a global development effort, investments mainly focused on military application in the US and green energy in Europe. The potentials used in the near future are small electricity consumption sensors. Companies like PowerCast and Wi Charge are developing technology for less electricity consumption sensors and retail stores, including smart lights, motion sensors and distance.

Emrod is working with partners in New Zealand and globally to test beam energy transmission technology. The company said the system of transmission and receiving equipment can achieve 95%efficiency. Emerod’s ultimate goal is to build a global grid, including trying to transmit electricity to remote communities. In called Worldwide Energy Matrix, the power grid in this space will use satellite to collect solar energy and transmit to any place needed around the world. Jaxa Japanese Space Agency also hopes to build a solar power plant in orbit to provide an electric gigawatt each year, equivalent to a commercial nuclear reactor.

The idea of ​​transmitting beam energy dates back to Nikola Tesla. As one of the greatest inventions in history, Tesla always has some bizarre ideas. His most ambitious project is the world wireless system. As the name implies, this system transmits electricity through the Earth’s electrolyte layer, using the planet itself as an electric conductor. For financial, practical and scientific reasons, Tesla’s system is forgotten. However, the idea of ​​wireless electrical transmission is still saved forever. According to Dr. Stephen Sweeney, Associate Professor Quang Tu Hoc and Nano Technology at the University of Glasgow, Tesla thinks about the touch method, namely using electric fields to create electricity somewhere. This way is effective on a short distance but when it goes further, it is no longer suitable.

The problem lies in finding a way to transmit electromagnetic waves. After many technological achievements in World War II, scientists found two answers to this conundrum questions: microwaves and lasers.

In 1964, American electric engineer William C. Brown successfully drove a small helicopter for 10 hours continuously through energy transmission by microwave. In 1975, Brown, along with scientist NASA Richard Dickson, transmitted 30 kilowatts directly through 1.6 km, using a microwave transmission beam from a 26 m diameter Venus with 50%efficiency. Both experiments are technical achievements, but the scale is not large enough to bring benefits.

For decades later, technological progress began to transmit beam energy from a new experiment into a necessary goal. These advances include the introduction of computers, photovoltaic batteries, lasers and semiconductor balls. Society also began to switch to electrification when faced with climate change.
