LED lamp battery without gravity, without battery ...

Better than the dynamo lamps: gravity lamp (light gravity) is not the blank or perpetual, just a few kg mass that slopes gently enough to provide long enough low power ...

So simple that nobody had thought!

But just brilliant, on a sailing boat there is already the mast, in case of calm flat, 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 ...!
A trick to take on Mars for the next space expedition, as emergency lighting ... !? : Lol:

Great idea, I will copy it : Cheesy:
I will build a large 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 : Cheesy:
PS, I have a consumption of 500w / h

We knew the use of a weight to make a pendulum or a rotisserie walk. Super, the idea of ​​using it to produce some electricity for miscellaneous use!

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

It is not bad at all as concept, especially the price and lack of high-tech element and wears out (batteries ...)

Good evening, in fact I have seen that the association of the link searches for funds for their project, there are various products in the trade of which a part of the fund goes to associations

Ex: bundles of diapers sold equals, funds donated for vaccines in third world countries

So here a product of the daily life, of which a part of the funds returned to the association that will allow them to realize their project of led lamp with gravity on a larger scale

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

Today we see dynamo lamps with crank, trigger or wire pull, I suppose that this system is currently only used for lighting

In the video I saw that they connected wires to the device to power some thing but we do not see what

There are a few years, I put magnets in magnetic levitation in a tube on which I made a coil.
When we walked it produced energy, but just enough to illuminate with LED
So no wonder it takes a heavy thing which produces nothing much!
