On the funding site you get one for $70USD. If that isn't about 20 times what they will sell for in Africa the target audience won't be able to afford it.

Many great ideas to help the impoverished end up selling for prices that are even high by US standards and are therefore useless except to western hoarders/preppers/campers/hunters etc.

 

I don't think it is very complicated at all. It uses gravity to turn potential energy into kinetic energy. The technology has been around for a very long time. Well, Lifting 12 kg 6 or more feet every 20 minutes to get one tenth of a watt is to me like killing a mosquito with a machine gun. I don't see people using kerosene or candle light, bcs there's nothing better, having use for: can also power other devices, such as a radio. You will find a DC jack at the back of GLO1 for connecting SatLights and/or other devices.

Pinch light as I called this and developed during the war is according to Wikipedia : A dyno torch, dynamo torch, or squeeze flashlight is a flashlight or pocket torch which stores energy in a flywheel. The user repeatedly squeezes a handle to spin a flywheel inside the flashlight, attached to a small dynamo, supplying electric current to an incandescent bulb or light-emitting diode. The flashlight must be pumped continuously during use, with the flywheel turning the generator between squeezes to keep the light going continuously

 

I am interested to see how they work in real world situation. I can think of a few uses for family/relatives in the province if they prove to be useful and don't fall apart after the 2nd use.
