Light switches do not work, where there is no electrical grid.

"Reminds me of the LED flashlights that you shake for 20 seconds and then they are suppose to give you 30 minutes of light." I have one of those in my hurricane prepardness chest. It works suprisingly well.

Get three of them then...
3 X zero electricity is still zero.

Not sure what is patentable here. Clocks have been powered this way for centuries.
The key to this this device is the LEDs which are very efficient no matter what the power source.
To: the_devils_advocate_666
Yeah, but you have to enlist a bunch of pre-teen boys to power those things.

That looks interesting. It will be more interesting if the device can be made bright enough to read by.

Kind of like lighting your house with those glowing light sticks.

How about a wind-up lamp next?

Would that be a grandfather or cuckoo clock?

Great concept. If they just replace the led’s with an 1157 auto bulb (tail light/brake light) this could be built cheaply and last a loooooong time.

You gotta be kidding me.... the gravity lamp got beat out by a regular old amp meter?

And it’s art deco, too.

>>I like this device.<<
I do too - very elegant.
But its not actually powered by gravity - the potential energy comes from the human applied force of lifting the weight.

Does it have a plug in port to power an oxygen concentrator for emergency use during power outages?
