Gravity lamp could light developing world

Hi all

This is a truly fantastic invention and so simple too. This will make a huge difference for people all over the world. Especially for those in developing countries who either do not have access to electricity or cannot afford it..

A UK design duo have dreamed up a gravity-powered lamp which could bring light to remote regions of the developing world.

The GravityLight is powered by the gravity which results from filling a bag with rocks or sand and then slowly lowering it toward the ground.

A series of gears inside the light transfers the weight into energy. It takes three seconds to lift, which creates half-an-hour of light on its descent – and for free after the initial cost of buying the lamp.

All you have to pay for is the product which could be as little as £3.22 or $5.00. After that its free of fees...
Lots of kudos goes to these two guys..! Trying to make life a little easier for people who are in need.. I sincerely hope that these gravity lamps really will be sold at as low a price as possible. Even at £3.22 for many people in developing countries that is still a lot of money..

I shall be keeping my eyes on these and may even buy one myself..!

I read about this from Physics.org a while ago. It sounds like a cheap emergency light. This sounds like it may be a commercial refined product. An effective, affordable renewable light source. Thank god for LED creation, something science did that was good. They are presently researching putting information into LED light to teach us but also to brainwash us or make us buy a product. Talk about science supplying tools to opposite sides of the spectrum

No mention of it being available to anyone not in a third world country. I need to make a big one of these, I can reset it by lifting the two thousand lb load with my tractor bucket and have a cable running into the house. Maybe I can make this technology run my fridge and freezers A metal fulcrum could lift a ton if done right, no tractor even needed.

This may be of interest to you; Here is the inventors site and recent updates on the project (Video as well):

Thank you for posting this, very interesting idea which will help many.

These inventions are more important than anyone can imagine. I hope that the amazing people working towards bring light to all of the countries without see this and are able to get them asap.

Also I have to add that the components to make these lights will be the biggest challenge, made in China is not always as easy as it sounds.

This idea has been around an extremely long time even before these people "dreamed it up". They did not freaking dream it up, I first came across this concept when I was about 16, which was like half a dozen years ago... and it existed long before I ever heard of it. I'm just surprised it took so long for some one to commercialize on it. Probably because it seems dumb to most people if you have to keep lifting the weight back up. But in a 3rd world country where electricity is scarce it's not such a bad idea.

Where can I get one?

I'm guessing they use a system of gears to run a tiny generator. Gotta wonder if this could be a technique that could be tied with something like wind power to run a large system of power generation that stores wind power generation.

I made something like it in 1969 using a bicycle light bulb, a weight from a grandfather clock and an electric motor from a toy car.
My older cousin had stolen an "inventors box of tricks" (for the 10-15 year old) and when he got tired of it he unloaded it on me. There were Axels, springs, levers and pulleys and a number of small plastic disks with loads of holes in them arranged in concentric circles so that one could peg out ones own gearing.

Mine ran for about two minutes. Half an hour is so much better. And the LED light will be brighter.

I want one or two for my camping trips.

Here's a good example of a gravity-driven mechanical device, just to show how long the idea has been around:

en.wikipedia.org...

The idea is quite sound, for sure. To me, it is more of a "novel" idea at this point. When it can produce longer than half hour worth of light (from an LED that only takes mere milli-amps to power brightly) then I'll be pretty impressed.
