Stop4stuff:

Very cool device you made, I watched the video. It's creative thinking like yours that is to be admired. If you come up with other neat power device, please let us know. CM

Some may remember this "free" energy experiment. So I built it again for the 3rd time.

Money invested:
CM: $100,000
ShawnLG: $0

Time invested:
CM: Years
ShawnLG: 5 min

15 feet of wire was used as an antenna and the grown connected to a grounded object.

Nice.
What kind of ground are you using?

One time I connected a pretty log antenna to a blue led, grounded to mains ground, and was pretty suprised to see it lit without any resonant circuits.
After some fiddling I figured out that various rf hash and harmonics induced in ground wire by warious appliences powers the led, and antenan just capacitively coupled other end to ''real'' ground. It worked much netter when I connected it to grounded rod.

"What kind of ground are you using?" The house's heater, which I know is earth grounded.

I have a large metal sheet on my desk for solder-splash protection. If I wave my one arm in the air, I can light a low-voltage (red/yellow) high-brightness LEDs by touching them to the sheet. ^_^

I guess the fields from the nearby three-phase lines help.

BlackPlasma, omgpix plz! If you can show it working, you get points for simplicity

Guessing blackplasma's metal plate is grounded, it's obivous that he can light a led that way.

As I already mentioned, most house grounds often float with few volts of HF noise wich is usually enough to barely light a led just by capacitively coupling another leg to ''real'' ground,
by holding it by hand, connecting to a large metal objects, real earthed wire (works best) etc.

This may also have influenced shawnLG's setup (heater ground?) although I'm not sure.

Just need to recharge my camera and I'l post a pic of that 'phenomenon'.

Shawn:

Looks like you replicated a simpified tuned version of the Tate Ambient module U.S. patent 4,628,299

If so, it's not "free" environmental energy, it's running off of manmade RF or AC signals. Steve's challenge clearly says "FREE" in the title. Btw, R&D costs can be $0 when you take them from someone else, if so, you should have the decency to give Joe Tate some credit for 'your' submission.

Sorry CM, steve specified that

... By that I mean renewable energy, or energy that would otherwise have gone to waste such as ambient RF or EMI from your electronic toys.

but you are right, most of the ideas here would not work in a remote area of the planet with no electricity around to suck power from.

Also there is the small matter that a fairly dark-adapted eye can probably see an LED glowing at 1ÂµW or so. It would be more challenging to generate a more significant amount of power, e.g. 1W for free, as this could be used to power an iPod or mobile phone.

Hi again, Steve and folks.

I can generally just connect a LED to my mains ground, and it will be lit pretty well if I hold her in my hand.

It also works if I connecto another end to anything with significant (few pf) capacitance to ground, like alu box on pic. It worked with a TC toroid, few meters of wire unwrapped around my room, and etc.

Interestingly, nothing worked better than my body, even a large metal barrel I happened to have around.. LED is still brightest when I hold her by hand.

This may explain some of 'mysterious' free energies appearing between various ungrounded objects and mains ground. Mains ground noise actually _is_ what provides power to LED.

I don't think it's some kind of renewable energy source but rather 'waste' power wich steve also allowed.

It costs nothing, but power generated isn't of much use.

At this time, here is apocalyptically cloudy, so no solar cells

But we have pretty much enough wind...
