Wireless Power Transfer

In case you didn't try this:-

google wireless power transmission Japan

Of course leaving "Japan" out of the search will give lots of other results.

Oh no not again! ... make the nasty men stop...

This is not new. Over 95% of the energy or energy per unit of time (power) that exists on the Earth came wirelessly by radiation.

..."Wireless power techniques mainly fall into two categories, non-radiative and radiative. In near field or non-radiative techniques, power is transferred over short distances by magnetic fields using inductive coupling between coils of wire, or by electric fields using capacitive coupling between metal electrodes.^[2][3][4][5] Inductive coupling is the most widely used wireless technology; its applications include charging handheld devices like phones and electric toothbrushes, RFID tags, and wirelessly charging or continuous wireless power transfer in implantable medical devices like artificial cardiac pacemakers, or electric vehicles.

In far-field or radiative techniques, also called power beaming, power is transferred by beams of electromagnetic radiation, like microwaves or laserbeams. These techniques can transport energy longer distances but must be aimed at the receiver. Proposed applications for this type are solar power satellites, and wireless powered drone aircraft.^[6][7][8]

An important issue associated with all wireless power systems is limiting the exposure of people and other living things to potentially injurious electromagnetic fields.^[9][10]"...

Don't forget the 'limitations' of the "Inverse-Square Law" upon wireless transmission of energy.

That's not a limitation, its an aspect to be utilized for safety.

Can you imagine the power level pouring out of Sol?

Far-field Transfer

To transfer energy wirelessly over long ranges, far-field transfer is used. Far-field transfer is based on electromagnetic wave which is radiative. Different methods use electromagnetic waves within different wave band. In the early times, experiments were carried out with radio and microwaves, around 1GHz. [4] Electric energy is transferred to a strong beam of radio or microwave by a dish-like antenna, travels through the atmosphere and then received by another antenna which transfers it back to AC electric current, as shown in Fig 2.

Yet according to diffraction, the longer the wavelength is, the larger the antennas must be in order to achieve sufficient directionality. Since speed of light in the air is about 3 x 10⁸ m/s, the corresponding wavelength of radio and microwaves used is about one meter, which requires an antenna with a dimension of several meters to several kilometers. Thus we have to use electromagnetic waves with shorter wavelength if we want to transfer energy to smaller objects. Moreover, since the electromagnetic wave used lies in the waveband of radio, TV, cell phone and Wi-Fi, with a signal intensity several order-of-magnitude larger, you probably won't want it any close to residences or offices - in fact, it was proposed to be used in energy transfer between future solar power satellites and the earth. [5]

Here Comes the Laser

Benefiting from advanced technology in both solid-state lasers and photovoltaic cells (notice that monochromatic photovoltaic cells are more efficient than ordinary solar cells) today, converting energy into laser beams to transfer over long distances is becoming closer to practice. NASA has made a model plane powered by a laser beam focused on a panel of photovoltaic cells on its ventral, see Fig 3. [6,7] Comparing to radio and microwaves, laser has many advantages like short wavelength (shorter than several micrometers), good beam width, perfect directionality and non-interference with radio, TV, cell phone or Wi-Fi signals. But it still has many drawbacks, like relatively lower efficiency during conversion and atmospheric absorption."...

Thanks a lot for the post responding to the querry. I learnt lot.

It is an old pipe dream.

In the set of books published in +-1935 (Standard University ) wide professors stated that trains will soon be powered wirelessly. (I have the book somewhere but after a stroke I dont find stuff that easy)

The problem in 1935 was that there was no CR4 to tell them NO NO NO;.l

I believe Tesla was the culprit .

Jeez!!!!!!!!!!!!!!!!!!!

I wear a tin foil hat 12 hours every day! Even then I get headaches and hear voices telling me to kill (name withheld due to safety reasons)

If we start putting power out into the air, where will it all end?????????

Copper is your friend! Plug that cord in and save humanity!!!!!!
