Saltwater light bulb
I'm going to have to goof around with this. I have many questions.
Drop a magnet into saltwater, put in an LED bulb and it lights.

Could leave little kits around for emergency if they power the light any length of time.

bs. yes lightbulbs with built in batteries are handy in emergencies
saltwater and magnets do nothing!0 -
well I just had to try it[:(] 0 -

I didn't see how it could produce that much electricity, so I had to try too.
Don't know what I was thinking. I knew better, but then again a potato has magic powers...0 -
This is total bologna. without boring technical jargon.
1) There is nothing to generate an EMF. A simple battery would need an anode and cathode. the saltwater could be the ion transfer vehicle, but again there is no ION donor. there are many fun electrical things to do with magnets. Dropping a magnet in salt water and creating enough voltage to light a bulb...come on.
2) If you had a simple battery, you could not immersed the hold bottom of the light bulb. the socket on the bottom of the bulb is designed with an insulator between the + and - or the L1 and N, it is in the circuit or completes a circuit.
3) anytime you see anything for FREE, and you are getting something for nothing, you know that is BS... you don,t know Newtons laws of Thermodynamics, basic economics, OR you VOTED FOR OBAMA and are in the DEMOCRATIC PARTY.0 -
I bet some of your old farts bought a pair of these when you were kid [:D][:D] if you went for teh water and light idea [}:)][}:)]
I would have but a dollar might as well been a hundred for me as a kid [B)]0 -
no I didn't[;)] but I wanted a pair[:D] 0 -

Yes. A potential problem with the design.

25? shipping? No zip code? Sounds a bit fishy to me.
Is the company still in business or did one of the tsa or other spy groups assimilate them and the technology. I smell a conspiracy.
Never knew anybody who bought a pair of them.0 -

You flat earth people...
Please explain the difference between gravity and magnetic field.
Google is not your friend on this one. [;)]
There is some validity to "junk" science. [8D]0 -

I see what you did there.0 -
I never bought a pair of X-Ray specs, but did fork out a buck for some Sea Monkey's![:D]
I think the company that sold them had something to do with P.T. Barnum!0 -

The link on the subject post probably doesn't work. However the link I posted does work with salt water as it has a proper design with anode / cathode and doesn't use a magnet. They are selling the light in lots of 100.
More direct link: http://www.salt.ph/
Scroll down to there it reads: HOW TO USE and then read and arrow right.
Also this handy schematic. Think I did a science lab test using a potato 60 years ago.
Didn't Tesla say the world is a battery.[:D]0 -
I bought a similar product around 1950. It was more like a tube you looked through though. BTW D-R, I am not old! 0 -
Old is a state of mind I am 61 body feels lie it most days
my mind still thinks I am 30 until I look in a mirror or a nice looking young lady maybe a waitress says something like "do you have your golden buckeye card handy" ( a card issued to to older generation here in Ohio for a discount ) [B)][B)][B)]
by the way the one comic book item in add's I wanted was the machine gun BB gun that ran on Freon [:D][:D] I head later on they were fun and actually worked .. I think like 5.00 or so at the time
