I have seen those detractors as well. They feed the ignorant and weak. We have the map to that mine field. 😉
Unfortunately, that 1896 article was a deathknell for free energy research that has rung for over a century, because the prediction that Tesla's discoveries would destroy energy using monopolies was taken as a battle cry againt them ... and we know the rest of the story. We are literally grave diggers trying to resurrect those discoveries, and decoders of documents obscured for those of us that venture to understand.
The problem with some innovators/inventors: immediately, upon discovery, they herald their success before securing enough working models and private demonstrations to carry their discoveries forward in a world of power and greed. They are silenced and demonized. The list is enought to show malintent.
One should know: patenting ideas is expensive; easily stolen by nations without civil restraint to honor the patenter. One has to rush to document an idea before someone in litigious societies, such as Europe or the U.S., begins manufacturing it without constraint or royalties. Yet, as soon as the document is filed, it is copied, manufactured and exported by other, unscrupulous, slave-labor nations without any recourse for the patenter.
Long ago, someone had designed a circuit for aerial reconnaisance. It was patentable, but the company lawyers said that once documented, it became the intellectual property of the company, and thus, forfeited to the government for whom it was being produced. The company saw no benefit to funding a patent for the government.
Recently there was a member of several forums gleaning ideas to produce his own medical device(s). He projected his covert objective upon several experimenters to misdirect others. Many ideas were shared with him before he was expelled. Had he achieved his goal, he would have likely joined the "silenced" list because of aggresion and indiscretion. Anyone associated with him ... jeopardized.
That 1896 article brings to mind how vulnerable we are to disruption and diversion, and that we must pocket some discoveries we share collectively until we have readily reproducable devices. When practical, the directions for reproduction of devices that are unchallenging to the energy industry, should be mass distributed. Once simple free energy devices become common, we can to tout our greater discoveries more freely.
