The scientific method is to prove the reality of our world, for reproducibility, verifiable by all constantly, as are checked constantly, the laws of electromagnetism, discovered by Faraday and Maxwell, every time we use n 'any device, TV, phone, GPS, etc .. nuclear
Again you are confused! Just an invention to be performed and experienced (even if only once) to be considered as concrete and therefore feasible. The fact that it is not feasible by others, it appears from the protection of the invention to maintain its exclusivity and therefore the trial copy that follow.
Tesla was an inventor and not a businessman that has earned him his to exploit several times "scalded cat fears cold water."
but a work of patience, careful, thorough, accepting the reality with great care, so that it is reproducible ....
This is where you still make confusion, it should not be reproducible by all THAT if the invention is and remains protected and author living, unfortunately it is no longer possible now seen the costs of removal European or global patents.
... .By All, understandable and consistent, verifiable at every moment taking care with great care and rigor, not to mix everything wrong, as I see constantly on econology, plus the refusal to make the necessary efforts rigor and understanding of centuries of scientific work.
Again another confusion, most inventors fumbled with successive failures in the key, including those that you quote. You confuse invention and industrial exploitation in the final stage; between the two there are usually imperfect prototypes and therefore "unscientific" as your terminology.
Apparently you've never invented anything!
