In the Marconi system of the present time there are many forms of coherers, also the magnetic detector and other variations of the original apparatus. Other systems more or less prominent are the Lodge-Muirhead of England, Braun-Siemens of Germany and those of DeForest and Fessenden of America. The electrolytic detector with the paste between the tin blocks belongs to the system of DeForest.

Others had accomplished this for similar distances, but they lacked Marconi's imagination and persistence, and failed to carry their experiments further. To the young Irish-Italian this was but a starting-point. Marconi quickly found that the receiver was the least effective part of the existing apparatus.
The coherer was still retained and by the end of 1900 enough had been accomplished to warrant Marconi in arranging for trans-Atlantic experiments between Poldhu, Cornwall and the United States, stations being located on Cape Cod and in Newfoundland. The trans-Atlantic transmission of signals was quite a different matter from working over 100 miles or so in Great Britain.
"Before you write 1903 I will have demonstrated the success of wireless communication," exclaimed Marconi, early in 1902; and ten days before the dawning of the year he named, the achievement was an undisputed success.
All of which makes us believe that if either Edison or Marconi had lived two hundred years ago, the bailiffs would have looked after them with the butt end of the law for the regulation of wizards and witches wizards at Menlo Park being as bad as witches at Salem.

The time had now come for Marconi to introduce himself and his discoveries to the attention of the world.
Will Hermann was forbidden the house at Morristown. Alice was practically a captive; her correspondence was censored. But of course, even before Marconi, wireless communication in matters of this kind has always been possible. The trouble was that the state of affairs between them, while conventionally correct, was thoroughly unnatural and full of peril.
There doesn't seem to be anything more I can do here, unless we get some news about Mrs. Edwards." Waldon seemed only too glad to agree, and no one on the Lucie insisted on our staying. We arrived at the Nautilus a few minutes later, and while we were lunching Kennedy dispatched the tender to the Marconi station with a note.
More astonishing still is the fact that in 1893, two years before Marconi demonstrated his system of wireless signaling, Tesla had built a model boat in which he combined power to drive it with radio control and robotics. He put the small boat in a lake in Madison Square Gardens in New York. Standing on the shore with a control box, he invited onlookers to suggest movements.
