World's first real Free Energy Flashlight - no shaking - no batteries! No Solar

They also say it can take 10-12 days to recharge when dead. It could likely be charged in less time with a small solar array in the handle.

Not sure where you got that from since the page Gravrock posted from Adgex's site says it takes 1 to 2 hours to recharge.   Where did you read it takes 10-12 days?   If true I guess you don't want to run it totally dead

thanx for the info.

it is a useful product. the developers deserve a successful future.
its not a cheap flashlight, though its price could soon lower with new versions.
without batteries, it must have capacitor based storage.
if it was a self charging battery, then it would be a capacitor.

Actually I have a lot of flashlights that are over $100 each.   But I mostly quit buying when I was up to around 80+ flashlights.   Some are one of a kind and I'm a collector.  If I hadn't just bought another this last week I'd probably have ordered this one but really trying to quit that addiction

Thanks Gravrock,  I had not noticed that explanation.   That would be great if they have harnessed that kind of power although I suspect it would be expensive or difficult to get enough that way for powering something big.   LED efficiency has increased so much in the last 10 years that it doesn't take a lot of power for 120 Lumens of light.

It takes 2 watts to power 120 lumens from a LED light source (see image below) and their flashlight will run for 12 hours before a recharge is needed.  According to Adgex, they can scale this up from watts to kilowatts (up to 10kW).  Don't kill the messenger!

Gravrock,  Jimboot, DreamThinkBuild - thanks for the additional info.   I just found this flashlight late last night and didn't have time to look deeper.  This sounds even better than I thought.   I didn't realize either they are talking about scaling it up.   Awesome news if it is for real.   I know other researchers have long talked about the power available from Earth lightning strikes and other similar sources.   It will be great if they really have a good (and affordable) way of tapping into that energy source.   


Note that Cree (LED manufacturer) has already broken the 300 Lumens per watt barrier.   This little light does 900 Lumens (U.S. Quarter next to it for size comparison) :

60 lumens per watt? Some LEDs are much more efficient than that.
