Folks, it's not a matter of whether this technology exists or not.
Actually, it is.
You see... if the technology exists - then one's task of creating it is merely a function of imitating what is proven.
If the technology does not currently exist - then it must be developed via speculation-guided trial-and-error.
You believe it does. There's a considerable difference.
If you're to ignorant to accept that, that's your issue. You only prove you haven't done your research.
Cute. Since you're so good at research - perhaps you should look my posts up and see how I've already addressed every single thing you're about to say.
Look into Nikola Tesla, EVERYONE!
Spent years studying the man's creations and methods.
Tell me what you would like to know about the man.
One of the more popular being wireless energy and LF waves, which are much safer than all of today's HF waves; Distribution of energy via a wireless tower.
You realize that was a massive tower putting out megavolts of electrostatic voltage potential, right?
Further - we don't use HF to transmit power. We use ELF - 60Hz (US) and 50 Hz (UK and some others) at 120/240 volts nominal RMS voltage.
You're going to tell me that giant towers that ionize enough local atmosphere that they look like a plasma-globe in the open atmosphere are safer than the current power infrastructure?
Do me a favor... you get a good idea to build something - give me enough time to build a space ship to get the hell out of here before you subject me to the casualties of your insanity.
His MAIN concept for free energy is harnessing the cosmic energy, available ANYWHERE and EVERYWHERE in the universe in UNLIMITED amounts. It was as simple as sticking a tin-foil like sheet of metal in the air, 2 wires running from it, one acting as a ground and the other as the positive feed. Look up his work, he is BRILLIANT.
Help me to understand... how is it that a piece of tin-foil is able to capture cosmic energy with two wires... and yet our massive sky-scrapers with huge plates of steel are not brimming with this captured energy?
Also... if it's such a simple and practical form of power... where's yours? It's just some tin foil and some wire, right... surely, even as a highschool kid, you could buy that at the store.
This alloy produces an EM field when heat is applied. Through the variations of heat, there is a respective frequency in the EM field. If one was able to harness the power of the magnetic field line, he/she would come across good power.
It's called a Peltier junction.
The difficulty with using peltier junctions (a joint of two dissimilar metals) for power generation using thermal deltas is that they are relatively inefficient as such - and a large amount of thermal energy crosses the junction. Since the power is derived from the difference in temperature (with a portion of the heat being converted to electricity) - you end up quickly losing any useful energy production as the temperature across the junction stabilizes.
You end up having to actively cool/heat one side or the other. If you're heating one side, you have to be sinking the energy that crosses the junction into a cooler source that can still provide a thermal difference.
In a closed system - it will eventually reach maximum entropy when enough heat spills over into your "cool" side to equal the temperature on the "hot" side. At that point, the device can extract no more energy from the system.
It is worth mentioning that this type of device, if it could operate at unity - would represent Maxwell's Demon.... and would result in what I define as a society that operates on null entropy (if energy exists above the "ground state" - it can be utilized, no matter how brief or intermittent). It technically breaks the laws of thermodynamics - but that law is much easier to see broken by comparison to the laws of conservation of energy.
