wi-tricity (wireless electricity) - electrical energy storage systems

Wireless power transmission is not a new idea.
Nikola Tesla showed the transmission of electricity without wires at the beginning of the 20 th century.
Tesla uses an induction system.
Tesla found that electricity can be transmitted through the Earth and the atmosphere.
During his research, he succeeded in lighting the light at a medium distance and was able to detect the transmitted energy at a further distance.
The wardencliffe Tower project is cross-
Atlantic wireless phone and proofof-
Concept demonstration of global wireless power transmission.
The facility was not completed due to insufficient funds.
The Earth is a natural conductive body and a conductor of the system.
The second path starts at a height of about 4 and passes through the upper and lower atmosphere. 5 miles.
A global system called the World Wireless System, "wire-free transmission of electric energy", dependent on the high conductivity of the plasma and the high conductivity of the Earth, was proposed as early as 1904 after World War II, the development of high-tech
The idea of using microwave to transmit power is studied, that is, the power microwave transmitter, that is, the cavity magnetic tube.
In 1964, William Brown demonstrated a model of a microwave power helicopter.
This receives all the power required for flight from the microwave beam.
In 1975, Bill Brown, without using the cable, transmitted 30 KW of the power within 1 mile with a 84% efficiency.
Japanese researcher hidesugu Yagi also studied wireless energy transmission using the directional array antenna he designed.
In February 1926, Bamu and Uda published their first paper.
The gain orientation array is now known as the batwood antenna.
While it has not proved particularly useful for power transmission, this beam antenna has been widely adopted in the broadcast and wireless telecom industries due to its excellent performance features.
A new breakthrough was made in 2006;
Using Electrodynamic Induction a physics research team led by a professor
Malin Solle jacic of MIT powered 60 W bulbs wirelessly from two distances of 40%-2 m, with an efficiency of 60 cmdiameter coils.
Researchers have developed several technologies that can move electricity from a distance without wires.
Some exist only as theories or prototypes, while others are already in use. 2.
The resonance induction coupling model here shows that electricity can be transmitted effectively over long distances using induction coupling.
It consists of two coils "induced coupling", that is, the magnetic field generated in one coil senses the magnetic field in the other coil.
However, one thing that distinguishes itself from the normal "transformer" type setting is that the magnetic flux in these coils has already vibrated at a specific frequency with the help of the capacitor.
This allows the two coils to efficiently transmit energy even over long distances!
Our focus here is to show that the use of resonant induction coupling can effectively transmit electricity for a few inches.
With a higher frequency and a more powerful output, this device can be used to eliminate the need for a power cord or extension cord.
The basic purpose and motivation of this project stems from the fact that in the modern world there is a shortage of electricity supply and excess demand.
The cost of maintaining power supply and making it equal to the growing demand for fossil fuels makes power production a daunting task.
With the world's fossil fuel reserves ending in the first half of the 21 st century, now is the perfect time to explore the use of alternative forms of electricity around the world.
The Sun, the water and the wind have been used to power the house, but these are also the resources of nature, considering that we live in a biosphere with limited resources, it is foolish to chase something natural to replace another one.
Therefore, the generation of electricity through resonance induction coupling and laser seems to be a useful alternative to solving the power crisis.
The project not only demonstrates the production of this power on a small scale, but also explores whether wireless power is a viable source of energy throughout the experiment.
By looking at the various strengths and weaknesses, we will be able to determine to what extent the future Radio force will take advantage of humanity.
The project has been inspired by MIT visionary people who want to use this power generation method after Tesla's discovery to benefit power producers around the world, reducing production burden and operating costs
There are several advantages to this new energy transfer model. 1.
Strong coupling of high resonance provides high efficiency at distance. This wireless power transmission mode is very effective at a distance of centimeters to several meters.
We define efficiency as the available electrical energy generated from the power supply.
This transmission mode can guarantee high efficiency due to its design. 2.
The energy transfer through the magnetic field can penetrate the obstacle and wrap the obstacle. The magnetic field has several properties that make it an excellent way to transmit energy in a typical consumer, commercial or industrial environment.
The most common building and decoration materials such as wood, gypsum wall panels, plastics, textiles, glass, bricks and concrete are basically "transparent" to magnetic fields "--
Enable this technology to transmit electricity effectively through them.
In addition, the magnetic near-field has the ability to "wind" many metal obstacles, otherwise they may block the magnetic field. 3. Non-
Radiation energy transmission is safe for human beings, while animal technology is not safe.
The radiation pattern of energy transfer depends on the magnetic field.
The interaction between magnetic fields and organisms is very weak.
People and animals
Considered safe.
Professor John Pendley of Imperial College London, a world-renowned physicist, explained: "The body reacts very strongly to the electric field, which is why you can cook chicken in a microwave.
But it does not respond to the magnetic field.
As far as we know, in terms of the power it absorbs, the body's response to the magnetic field is almost zero. "4.
The scalable design enables solutions from milliwatts to kilowatts. The system can handle various power levels.
Power levels from milliwatts to several kilowatts can achieve the benefits of high-efficiency energy transmission at a long distance.
This enables this technology to be used with a wireless mouse or keyboard (milliwatts)
Charging electric passenger cars (kilowatts). How to build it?
Wrap the coil to 8 by 4 inch.
There should be at least 35 laps. We used 35.
Do two such coils
Remember, some endings are missing.
Scrape off the edge of the end of each coil.
This will cause their insulation to fall off.
Do this for all your coils.
These are pictures of the launch coil and the launch coil.
Insert all wires as shown in the circuit.
Look, it works.
You do need to fiddle with the oscilloscope a little, though.
Watch Magic :)
The greater the distance, the darker the lights.
The second model is easy to build.
We bought a solar panel from the market.
Connect it to the led.
We use a class 2 laser to charge the solar panel for 5 hours in a row for a useful power output.
Then use it.
This model is made of foam.
We covered it with a black chart paper to give a spatial effect.
We drew blue and green bottoms for the Earth.
