Gravity Light
« on: February 06, 2013, 09:35:17 AM »
This looks legitimate!

Quote
GravityLight is a revolutionary new approach to storing energy and creating illumination. It takes only 3 seconds to lift the weight which powers GravityLight, creating 30 minutes of light on its descent. For free.

Following the initial inspiration of using gravity, and years of perspiration, we have refined the design and it is now ready for production. We need your help to fund the tooling, manufacture and distribution of at least 1000 gravity powered lights. We will gift them to villagers in both Africa and India to use regularly. The follow-up research will tell us how well the lights met their needs, and enable us to refine the design for a more efficient MK2 version.

To achieve this we launched a fundraising campaign on Indiegogo and we have been thrilled by the support shown during the first 24 hours of the campaign start. But it's not yet over we still need your support by contributing to the project and spreading the word.

Hi MileHigh
I've got the same idea couple months ago. It is good only if we consider 1 LED as a source of light. However one 24 LED /smd 5050 type/ bulb takes 4,8 Watts of power (which is absolute minimum for normal living in a small room). For this bulb when we use 100 kg weight hanging it 2 meters up we've got time of falling ar. 417 sec which is 7 minutes. That means; every 7 minutes you have to lift your 100kg weight 2 meters up. For one such a LED the time increases to ar. 3 hours, 50kg weight will give 90 minutes..

E = m*G*h, E = 100kg*10 N/kg*2m = 2000Nm = 2kJ, J = W*s, 2000J = 4,8W*417s

So.. we need to wait for more efficient sources of light to make this idea happen.

All the best.

I've been telling everyone for years to use clock work weights to use as a gravity to energy conversion, finally someone listened.

nice work.
