If you think he was serious, then you know nothing of the man or his contributions.

I didn't take him literally. I understood the quote to mean that there is more to understand then what is already understood. That is also how I interpreted my friend in our discussion of antennas. If he was wrong then so be it.

 

Over unity comes in many forms.

A popular theme in SciFi is to have solar farms in orbit (where the sun always shines) and beam the energy down to earth as microwaves. The power density can be quite low and still be effective, but the antenna farm will cover square miles.

 

I think Nicola Tesla beat you to the dream of wireless electricity.
Take a look at these:

...and now a renewed interest...

If the power companies keep raising their rates, people will find alternative ways to provide power (including thermal, solar, wind and hydro).

my 2¢ (might not be worth a plug nickel).

 

As great as Tesla was in the field of power generation, wireless distribution of electricity was not one of his brighter ideas. He never made it work nor has anyone else since, other than over very short distances and at fairly low efficiencies.

Tesla was a genius of the 1st magnitude. There have been a lot of reports that he did make it work (though I wouldn't even try to guess at the efficiency). He did make mistakes, but his successes were a lot more frequent and impressive. I wish we had more info on his theory.

With all the attention I wouldn't be surprised if it wasn't "rediscovered". There were some powerful interests in burying it at the time.

I claim nothing with certainty, I just don't think all the facts are in yet. As in the microwaves, there are other forms of broadcast energy that may be exploited.

 

On way of looking at an antenna is: The antenna matches the impedance of the transmission line to the impedance of air.
Another person who claims to have gotten great amounts of electrical energy from the atmosphere was T.H. Moray. There is more written about this in book called the sea of energy.
Doing a google search for T.H. Moray gives a lot of hits.

Several years ago I built an active antenna for the AM broadcast band. This consisted of a parallel resonate circuit, RF amplifier and then a emitter follower. The antenna was a telescoping whip about 20 inchs long that was connecte to the hot side of the parallel resonate circuit. I was about 10 miles from the closest AM transmitter. I had 2 volts peak to peak amplitude on hot side of the resonate circuit at the frequency of the local AM transmitter.

On the same token I have been able to have florescent tubes illuminate in a strong RF field. This was near the transmitting antenna

The point I'm trying to make is that the magnetic field of a radio transmitter is so week at a considerable distance that to get a usuable amount of energy is not possible.

 

I think anyone who understands theory can differentiate between deliberately harnessing power created for the purpose vs. trying to take advantage of what is out there. Lasers and Masers make concentrated beams for the purpose, instead of omnidirectional broadcasts where the inverse square law rules.

 

Sorry for digging up this old thread but I was searching about the same thing and since here you are all nay sayers about the concept well I present you those guyz who seem to made it work https://www.kickstarter.com/projects/nikolalabs/nikola-phone-case-power-your-phone-with-wasted-ene

 

Welcome to AAC!
How do you know those guys made it work? I see no evidence in that link that this proposal would actually be practical. Wouldn't you have to stand around all day every day close to a powerful cell-phone transmitter? All I see is an invitation for people to part with their cash!
BTW, you are more likely to get a response if you start your own thread rather than dig up an old one. It is bad practice to hijack someone else's thread.

 

Well, if you can charge a decent size battery from radio waves etc, let me know. I will invest in that tech. maybe.

 

You can charge a battery from solar cells easier and faster than from an antenna.

"How to charge a batter faster?" is an other question in my opinion and your argument belongs to that question.

Here the thing is how much time can we use devices between charges and this patent seems to increase that time by 30% which for a prototype isnt bad...

 

Ask Nicola Tesla .. he might be able to answer you ..
