Very nice invention!
That could really be a life saver and is very awesome as an emergency flashlight.
It probably won’t put out a lot of light, but when everything else fails, some is better than none.
Edit: I now see they mention 24 lumens. Should be sufficient.
I wonder if she tied it in with a joule thief, she is using a Seebeck generator (thermoelectric) plate (peltier) to make electricity
In the video she never mentions it, could help kick up the available volts to make the light brighter
Same principle behind the BioLite, but with alot less heat
Either way...that is WAY cool!
Copper mou… Okay okay …I wont.
Very cool story, they should include these with the drinking straw that purifies water.
Drinking straw can be packaged in the hollow aluminum tube for shipping ;)
