Exploring Wireless Power: Research and Startups for Cordless Electronic Charging

In summary: I think it will be the main research area in near futureSee you next mondayIn summary, there are a number of ways to generate wireless power, but none of them are very feasible.

Are you reading the posts in this thread? Nobody has ever disagreed with the fact that you can broadcast power. There is no doubt about that, and no need to bring in Nicola Tesla as the forlorn forgotten genius. The method is simply inefficient, you must broadcast orders of magnitude more power then is received by any single antenna. The system is wasteful and is this day and age it is ludicrous to even consider.

Reflection of broadcast power for improved efficiency

The afforementioned microwave-oven utilizes broadcast power. Microwave ovens are notoriously efficient...

...thanks to their wave-reflector systems.

Every microwave oven manufacturer has a wave reflector system, which is nothing but the cavity itself.

Have you read a single post in this thread?

Use wind. blow a strong wind towards component that has fan attached to it and connected to magnet that spins and produces energy. Less harmful than microwaves, but got to deal with a lot of messy hair.:rolleyes:

Hitssquad, (to let you know what Integral was getting at...), the concept of a microwave oven cannot be used for transmission of power for some fairly obvious reasons: You could certainly turn your living-room into a room-sized microwave oven, but consider the logic of sitting inside it to power the laptop computer on your lap... :bugeye:

Besides, I'm not sure a microwave really qualifies as a point-to-point transmission of power, since the receiver is inside the transmitting device.

Well Tesla system have nothing in commun with radio transmission.
Check these recents tests.

Edited to add
The Magnifying Transmitter by Nikola Tesla :

Now about my presentation
the only test to verified if it exist actually a system operated for secret military purpose is to build the receiver system describe ie_"To tap the energy of such a broadcast requires the construction of a tunable Tesla coil which either operates at 14.3KHz or some even super harmonic of it."_
see full description on my previous post above.
