This will be a thread about the History of both Wireless Information and Wireless Energy.
Here is a copy of a paper called the "full" history of wireless....
funny no Tesla so its no where near complete!
Still dispite that fact, it has good information, but a little retarted to have no Tesla!

Since this story is critical to understanding wireless tranmission variablities, lets take it one step at a time.
As it is with any event in history, invention of a process is seldom the responsibility of only one singular person. Radio, as we know it, has been attributed to Guglimo Marconi, however his success was built upon the works of Hertz, Lodge and Branley, and Tesla.
Let us now take a trip back into history, Let’s even go back before Marconi was a twinkle in his parent’s eye!
The first transmission of electricity was due to electrostatic impulse.
This happened in 1860 by a man named Mahlon Loomis
The Early Days
Mahlon Loomis was born July 21, 1826, in Oppenhiem New York, into the family of Professor Nathan Loomis and Waitie Loomis. He was the fourth of nine children.
Not a lot of details are available about Mahlon Loomis’ early life. This is unfortunate because it is often interesting to see how a young inventive mind grows. We do, however, know that he was surrounded by educated minds, as his father was a founder of the AMERICAN EPHEMERIS and NATIONAL ALMANAC. In addition to this, his older brother George, was an inventor and holder of several patents himself.
In 1836, Mahlon’s family moved to Springvale, Virginia. In September of 1848, Mahlon went to Cleveland, Ohio to partake in the study of dentistry. In 1850, he returned to Springvale to continue his dental work.
For several years Mahlon spent time as a traveling dentist. During this time he went to Earlville, New York, Cambridgeport Massachusetts and Philadelphia. During this practice in Massachusetts he received a patent for a mineral plate (Kaolin ) process for the making of artificial teeth.
In November of 1856, Loomis and his bride of only a few months, Achsah Ashley, settled in Washington D.C. to set up a dentistry practice.
But this is where our story really starts...the history of wireless transmission of electricity.
It begins with electrostatic impulse induction based on two kites made of copper mesh, with copper lines, one attatched to a galvinmeter and then to ground, the second one is touched to ground to send a signal....volia electrostatic impulse induction. Very good distances too, over 12 miles!
This type of transmission is termed Single Energy, as it only used Electrostatic Impulse Induction, nothing else.

A look at Wiki is also useful for some interesting items that relate to the wireless transmission of energy vs information. The flat spiral inductor. A simple device that fasinates me.The Start Of The Electrical Days
About 1860, Mahlon Loomis became interested in electricity, and his first application of this was an experiment in the forced increase of growth in plants. This was achieved by buried metal plates connected to an electrical current furnished by batteries.
In this same time period Mahlon became interested in using the electrical charges obtainable from the upper atmosphere by means of kites carrying metal wires. At first he planned to use this natural source of electricity to replace batteries on a telegraph circuit. It is noted in many references that this was something that was actually achieved on a telegraph line that was 400 miles long.
Later on, from experiments in this area, Mahlon discovered that a kite sent aloft would affect the flow of current in another kite that was some distance away from the first kite.
This set him on a path of developing it as a system of wireless telegraphy for practical long distance communications.
It Actually Works!
The year is 1868, and Mahlon Loomis demonstrates to a group of Congressmen and eminent scientists a wireless "communication" system between two sites 14 to 18 miles apart. There seems to be some discrepancy as to the distance in the various records that exist, however in the picture that was drawn by Mahlon Loomis, 14 miles is mentioned. This and many other pictures and notes are on file in the Library of Congress.
From one mountain peak he sent up a kite, the bottom of which was covered with thin copper gauze, and the kite string was copper wire. He connected this apparatus up to a galvometer that had the other end of the circuit connected to ground. Immediately the galvometer showed the passage of current!
He then set up an identical outfit on a mountain peak 18 miles away, to send. He would touch this second kites wire to ground and by this action reduced the voltage of the charged stratum and lowered the deflection in the galvometer attached to the other kite at first location we discussed.
There were problems with the communications system sometimes. It seemed that if one of the kites was at the wrong height, the system would not work. This led Loomis to believe that there were different areas in the atmosphere, and depending which area you were in, would control if the communication would work or not.
There were even days when the system just would not work at all. In thinking about that, I suppose it could be due to the electrostatic charge in the atmosphere that existed at that time during the experiment.
Mahlon Seeks the Government’s Help
Senator Charles Sumner, encouraged by a previous government grant to Samuel F.B. Morse, introduced a bill into the Senate on January 13, 1869. The "Loomis Aerial Telegraph Bill" asked for an act of incorporation for the Loomis Aerial Telegraph Company, and for the appropriation of $50,000 to help perfect Loomis’s discovery and make it practical.
Loomis had proposed a system where wireless telegraph messages could be sent across the Atlantic at 1/16 the cost of what it was using a Trans-Atlantic cable.
In an address to Congress, Loomis explained his system worked by: "Causing electrical vibrations or waves to pass around the world, as upon the surface of some quiet lake one wave circlet follows another from the point of the disturbance to the remotest shores, so that from any other mountain top upon the globe another conductor, which shall pierce this plane and receive the impressed vibration, may be connected to an indicator which will mark the length and duration of the vibration; and indicate by any agreed system of notation, convertible into human language, the message of the operator at the point of the first disturbance."
The bill, although gaining the support of a few Congressmen, was thought to be a fraud by many others. It was shuttled from committee to committee with much delay.
On May 20 thru 21, 1872, a lengthy discussion took place in the House. The issue of appropriations had been removed from the bill, and issue of incorporation was all that remained of the Loomis bill.
The newspapers became extremely active on the Loomis issue, unfortunately the majority of them were not favorable to the concept of wireless communication. Their reports ranged from polite skepticism to outright ridicule and allegations of the Loomis method being a fraud!
A copy of the Loomis Bill was also submitted to the committee for patents. On July 30, 1872, Patent number 129,971 was issued to Mahlon Loomis.
