Ah, right, Then lets go to the ionosphere, where Tesla thought contained net Charge, which we now know that it doesnt.
But cosmic rays aside, then lets calculate the magnetic energy density at the ionosphere!!!
turns out, the farther away you are from the earth, the weaker the magnetic field is, which makes sense, the farther a piece of metal is from a magnet, the weaker the force is. You can test it out with your own fridge magnets.
Now back on track, the Earth's magnetic field at the ionosphere is typically around 25 nT (nano Teslas), thats right, unfortunately, its soo weak that its in the nano range, the 0.000000001, about 100 times weaker than on the surface of the Earth
Now to calculate the energy density of the magnetic field around the ionosphere.
25*10^-9/(2* permeability of free space) = 2.487*10^-10 J/m^3, about 6.76 million times weaker than on the surface of the earth. It is that many times smaller because energy density increases or decreases exponentially. I know thats not what you wanna hear, but unfortunately its the truth :/
sorry for the condescending tone, idk how else to write it out
Tesla did have a great mind, and the scientific community DOES acknowledge him A LOT. We have an SI unit named after him, for the magnitudes of magnetic fields. In case you don't know, ahving an SI unit named after you is the greatest honour in the world of science. Its even better than a nobel prize!
Tesla never actually planned on giving the world free power, he had an idea where the government or another philanthropist could possibly give free power to the people via wireless transmissions. however, no one was really willing to pay the electric bill for an entire city, let alone an entire country.
I actually know mroe about Tesla than i do of Edison, despite the contrary. I have 2 physics textbooks and 5 engineering textbooks. all of them mention Tesla, only 1 of the physics ones mention Edison, I really don't understand how the Tesla fad about no one ever acknowledging him came from.
