Better than dynamo lamps: the gravity light is not a blank or a perpetual, just a mass of a few kilograms that goes down slowly enough to provide a low power for a long time ...

So simple that nobody thought of it!

But just great, on a sailing boat there is already the dull, in case of flat calm, it is very useful ... In the mountains using a tree, in short almost everywhere it is possible.

And it could actually work on any planet ...!
Something to take on Mars for the next space expedition, like emergency lighting ...! ??

Great idea, I'm going to copy it
I am going to build a big swimming pool in the garden, which will store the energy of my solar panels
Christophe, can you calculate the size of the pool?
Two days of storage are enough for me
PS, I have a consumption of 500w / h

We knew the use of a weight to operate a pendulum or a rotisserie. Super, the idea of ​​using it to produce a little electricity for various purposes!

The LED should go out in 3-4 lumen (at 40 mW), if the light is directed it is enough to read a book.

It's not bad at all as a concept, especially the price and lack of high-tech element and wear (batteries ...)

Good evening, in fact I saw that the association of the link seeks funds for their project, there are various products in the trade of which parts of the funds are donated to associations

ex: diaper bundles sold equal, funds donated for vaccines in third world countries

so here a product of everyday life, part of the funds donated to the association that will allow them to realize their project of led lamp to gravity on a larger scale

I knew you would like it

Hello, in any case it is a great project gravity system for lamps or other and without batteries.

We often see nowadays dynamo lamps either crank, trigger or pull wire, I guess this system is currently used only for lighting

in the video i saw that they connected some wires to the device to feed something but we do not see what

A few years ago, I had magnetic levitation magnets in a tube on which I had made a winding.
When we walked it produced energy but just enough to light with diode
So no miracle, it takes a heavy thing that produces not much!
