Step 4Testing Wireless Power Through Different Materials
Yes, I decided to go a little further because of the response that I received.
You were always told as a kid, water and electricity DO NOT MIX, and that may be true, but not with wireless power. I tested this in water. No, I did not get shocked, but you may. NO! You will not I promise. This Step shows that this type of wireless power can pass through almost anything, except metal, I know, I was sad when i found that out. I mean, for a practical use, many people have desks made of metal where the coil is. This is not good, but I digress, we must move on.
Water! I mean who would think that this kind of technology has this kind of potential! It works that same exact way as if it was not in water. It is in a plastic bag as you can see. Only to protect the electronics. Unlike WiFi which is can be weakend by walls and other things, Wireless Power is not!

the transmitter was just a step up transformer connected then diconnected to a battery!
the recever was a led connected in parrelel with a 1N34A diode as my "cristal set." one end of the the led or Ne2 light woud flash!
Can you be more specific? Can you explain on the step-up transformer side? Transformers are supposed to work on AC, but you mention it was connected to a battery. So I assume you were manually turning ON and OFF at a very high rate, correct?
Second, on the receiver side I guess you had both anodes connected together and both cathodes together. You do not mentioned the secondary coil, but i assumed you hooked up each end of the coil to both diodes. Is that correct? Or did you go with no secondary coil when using
the diode?
By the way, how many turns in your circuit?
u can use a oscillator on the transformer side if you like.. and the transformer i used was from a wall adapter (or a mains transformer) but it really doesn't matter as long is it gives off over 80 volts or a painful shock!
NNOOOOOOOO!! there are two separate circuits!!
check out the two schematics |

Don't try to power your whole house with this, as a number of possible effects could occur:
1.There is energy lost in the transfer from electric current to an electromagnetic field and again from magnetic field to electric current. Much less effieciency than a straight wire.
2. Metal things (ferrous metals, in particular, along with neodymium magnets) could start vibrating at the frequency of your transmitting coil.
3. Following idea 2 further, there could be residual voltages built up/stored in anything conductive. Possible shocking hazard, but as long as it's below 35 volts or so, you should be OK.
4.Computers, cell phones, pacemakers, anything sensitive to large amounts of magnetic fields will not work, unless properly shielded.
("Um, Grandpa? Don't come to my house, because I turned it into a giant solenoid....")
5. Landline phones are robust, but a strong, pulsing electromagnetic field near your house's phone line may cause phone conversations to turn into a contest to see who can yell "what?" the loudest.
But an upside is: this is way cooler!
Also: would you need a full wave bridge rectifier to get double the current coming from the oscillating LC tank circuit? Is the capacitor really needed for general power transfer purposes(aside from creating a resonant frequency)? I'm gonna get my circuit simulator out....
