What? not gravity-powered lightning?

Awww.

I actually misread it as that.

As did I. I think that my perception of what to expect is somewhat unrealistic.

What exactly do you think the gravity thing IS if not a rechargeable battery?

Also, the gravity  thingy doesn't need to have a rechargeable chemical battery.

fixed. Happy now

And technically, it isn't a battery, just a piece of clockwork and a powergenerator. It's a way of storing energy yes, but if you count it as a battery, then pretty much everything is

"battery" usually refers to a series of electrochemical cells, in the original usage as in "battery of artillery", since you'd see all the pots of acid all lined up, but I guess you could say nowadays it just means "power storage thing"

Well, if it means anything, I still distinguish between cells and batteries.

There are a variety of mechanical battery systems though, such as flywheels.

Okay, I don't want to sound mean to the guy, but he hopes his design can sell for 10$ once mass produced. You can order a hand cranked flashlight from Amazon for 5$. He is wasting his time.

I've never seen a hand-crank flashlight give off nearly as much light as shown in videos of the gravity light. Also, hand cranks are a PITA to hand-crank.

Flashlights don't come with a stand and aren't designed to disperse light throughout a room.
I'd rather pay $10 to replace my kerosene lamp than pay $5 for a flashlight.

What? His light is a single LED for fuck's sake. I've got a flashlight that emit way more light than this. Also, it means the technology behind hand-crakend flashlight (aka, a battery) is cheaper than his, doesn't weight several kilograms and you don't need your lamp to be the size of a grandfather clock.

Hell, you can get a solar/handcrank lantern with 12 leds for the price of his thing.

And the problem with most crank-lamps is that the crank is tiny as shit. What he should have done is just sold one with a bigger crank. That would have made me happy anyway.

That's correct, but handcrank/solar flashlights use batteries, which limits their lifespan to 500, maybe 1000 recharges at most. You can't use much more than a single LED if you try to generate energy without using batteries.
