Gravity Light

Has anyone else seen this? It’s a pretty awesome idea, and I like that it’s targeted at developing areas.

The video had a lot of emotional stuff but almost nothing about the light.

What about the light itself? Why don’t these people try to promote these things to Western Preppers?

Agreed, a lot of reading to get to runtime, no detail for output or the fact that is a power generation plus satellites…(maybe?)

A good vaccine made in America. Much more lovely...

Micro...Soft.

Because most people aren’t going to mount anchors in their ceilings and lift 5 kilos every half hour for a paltry 5-10 lumens.

Even for emergency purposes, I wouldn’t purchase these lights. I’m not sure how many 26650s, 18650s, 18350s, 16340s, 14500s, 10440s, plus a litany of NiMH cells that I happen to have on hand in various states of charge; but I’m sure that I’ve got more than enough to supply a couple hundred lumens for over thirty nights. I could stretch that to over a year at 10 lumens. And in a real pinch, I could take one of these from off my gatepost.

The point is that we are interested in the light itself, and they didn’t tell us about it………… and preppers are interested in such things.

Relax, you don’t need to try and crush other opinions than your own.

I saw this today at Get smarter every day yt chenel, this product is intended for poor people in countries like africa that are off grid and vould use hazardous kerosene lamps usually. It is intended tha the product price would be 6 (six) $.
You could find some more informations online before starting to criticize something that is not to your liking…

first of all “Gravity Light” sounds attractive and imaginative .

A single 2000mAh AA battery (such as a regular Eneloop NiMH rechargeable) has enough energy in it to lift a 70kg man to a height of 13 meters (43 feet). That’s how much weight and height you’d have to provide (probably at least double that, to allow for inefficiency) to power a 1xAA light for as long as a single AA battery can. Quadruple that number for a 1x18650 light.

It’s a dumb way to power something. Okay, maybe useful in a 3rd world village, but they probably have more pressing needs than LED lighting, like clean water.

For any preppers, just keep a few AA batteries charged up, and save your energy for something else when SHTF.

More reliable than wind-up lights but yeah, limited applications and cost issues when you’re talking about the poorest people who can eat better than normal for a week with the same money. And maybe not the best solution for the more affluent either. The concept is good, the execution isn’t there yet but maybe someday.
