Yes we all know that you there is no such thing as electricity for free and in the attached youtube video, the magnet passing between the two spark plugs is generating some electricity, but there is no circuit ! What is going on, and how can a LED bulb which normally functions off 240volts AC can run off what I assume is a low voltage. Come on you brain boxes - what's happening. Ps skip through most of the video as its a bit boring.

There are a number of similar views, I saw one with a couple of ball bearing races, a couple of small motors etc - that was pretty impressive too.

The interweb is awash with videos of similar nature, perpetual motion and the like. They all owe more to nifty video editing than they do to scientific principles. You are without doubt being had over wink

There are some other videos around showing you how the trickery is done

They're quite clever

If it looks too good to be true etc applies

LEDs only need a forward voltage of 0.6V (the usual silicon type) and most are only rated for 250mW at the max, so it won't take a great deal of energy to light it faintly.

Try neons in your microwave to find if the microwave distribution is up to scratch (need something else, as well, in there to absorb the radiation). Works a treat.

There was a rumour that someone in America built a huge coil under a powerline to create inducted electricity. Don't know if it would work?

A 40W equivalent LED light bulb only needs about 5W of power at 3Vdc approx and the electronics in the bulb are a simple power supply that drops mains down to that value. The bulb itself is easily dismantled and it would be possible to hide a battery and a reed switch (these are operated by a magnetic field) inside the holder. In the video I think the switch is hidden under the wooden board between the spark plugs - we never got to see that side!

A much smaller LED than 5W would create the effect of a lit bulb. My guess is a smaller LED was used, this type from amazon are 3V at 20mA. Lighting one is an easy job for a couple of AA cells. (I see you get 100 of them for £1.31 too, postage free!)

Either the video is a fake or all our energy problems are over!

I have read a report published by a US research organisation on methods by which amounts of power sufficient to run clandestine radios by special forces could be derived. One method involved a long loop of wire running parallel to an overhead power line. For example one leg of the loop would be under the line and the other some distance away, the length being hundreds of metres. Enough magnetic flux can link the loop to generate useful power in the right conditions, watts rather than kW, but enough. One leg could be an existing run of wire such as a strand of a wire fence.

But a large coil directly under a power line won't link any useful flux, it needs some asymmetry.

The original T&Cs for my amateur radio licence, back in the 1970s, banned end-fed wire antennas longer than, I think, 75 feet. That was because in the early days of radio people near the long wave transmitters were extracting enough energy to power a light bulb or two.

A friend carefully removed the cap of a bayonet cap lamp and broke the glass to remove the filament carrier. He then fitted a torch bulb and battery inside and wired it to the two terminals and refitted the cap. Shorting the terminals with a finger ring lit the lamp with no wires to be seen, of course it did need to be a pearl type lamp to hide the trickery.

Yes we all know that you there is no such thing as electricity for free

Not so - I get up to 3Kw totally free when the sun shines in summer & up to 2Kw in winter.

I just let a company called A Shade Greener fill the south facing side of my roof with solar PV panels - they own the panels & are responsible for maintaing them for 25 years. They get paid the Feed in tariffs & I get to use all the electricity they produce at no cost. At the end of the 25 year period (when the Fits end) they give me the installation FoC, so totally free electricity.

Not so free if and when you wish to sell your house. The legalities, etc likely cost the vendor thousands. These rented roofs are a minefield for potential house purchasers. Far better to install your own kit and avoid the third party renters of equipment. They will go mostly go out of fashion when the FIT scheme finishes in a couple of months time. Doubtless they will come up with some other money spinning scheme...

RF Energy ? two aerials and a sig gen off screen, bit like we used to get flourescents lighting up under a pylon.

When I was a young radar mechanic a friend put a fluorescent tube up in a gum tree and showed what happened when the x-band radar antenna was pointed at it.

A fairly narrow beam, 1MW pulses at a PRF of 1100 Hz (used to track mortar bombs).
We used this to spook the gunners with our magic lighting system.

Another trick was to plug an electric shaver into a tree trunk and have a shave. Battery powered razors were a new invention in those days so most artillery people had never heard of them (mid '70's)

Running clandestine radios from a large wire loop laid under a power line doesn't sound very clandestine to me. Also, one could detect the use f a superhet receiver by listening for its local oscillator, TV detector van style.
