Can I just get the ball rolling on page 1?

My worldview is that over time page 1 evolves into a page 2, then a page 3, etc.

Pages 4, 5, and 6 feel discriminated against for being called an "etc."

That brings up another thought. Are new pages created or are they the result of an evolution of the original topic, as new comments build upon previous comments - Survival of the Glibbest? Here, too, the questions remain - created, evolved or both?

 

And I am confident that my comments prove conclusively there is little intelligence in my design. :)

RF happens whether you want it to or not- I've had radios that would receive signals even when they were unplugged, and of course there's the famous case of teeth receiving signals. The power to create the noise is coming from somewhere. If you have a lightbulb set up for the right frequency, you can hold it in your hand and watch it light up if you're next to a radio tower (yes, I've done it).

 

Seems like you could make a recharger with a radio antenna to use that power- it'd be slow, but it would work. It would also interfere with all radios within a few feet.

It will be interesting to see the applications.

It's cool for devices that cannot conveniently be plugged in, such as pacemakers.

 

If there's a wireless car recharger at every stoplight, people who use their car in urban areas only can have electric cars with quite small batteries. Just a thought.

Nothing new in these technologies. Electromagnetic induction powers hover rail. Microwave powers er.... your microwave. The innovation will be to find applications that do not have safety issues. You can't just go beaming power through the air that is occupied by people or animals for that matter. Think of the furore over the use of mobile phones that transmit fractionally small amounts of electrical energy.

I'm scared.

 

Yes, rationally, it's probably safe. But have you seen the video of the popcorn being popped by ringing cell phones? I don't want to be a popcorn when something goes wrong.

The most common side effect from exposure to realistic levels of electro-magnetic radiation is that your children are born naked!

 

There is nothing novel about the demonstrations in the OP. They are simply attempts to attract investments from the uninformed. My toothbrush gets recharged using this technology.

 

Several replies here have mentioned "beams of power". The biggest defect is that the stuff does NOT beam at all - it spreads (and thus there are tremendous losses from transmitter to receiver).

 

As for the popped corn "caused" by the ringing cell phone - the ringing is a reaction to the signals that are there whether or not the cell phone is. The phone may transmit a low level "you have found me" signal, but it is no more powerful than any other signal from the phone. Another hoax!

Something which is intriguing is this:

The original site I found (since disappeared through time attrition) showed that they have actually got the thing working..2 hours of fire produces enough ice for 24 hours refrigeration (in Africa, so an accomplishment) and it does have the capacity to charge batteries. Would this be based on some sort of vortex tube? If that is a dumb question, forgive me..science in the schools I went to was less than inspiring so am entirely naive about such things.
