People, you know what this is the way. I was born and brought up in a remote part of Kenya where we light used tire pieces for house illumination. i only saw my electricity light when i was 19years and in college in urban Nairobi. Give us the solar lanterns please the sunlight here is from January to January 12 hrs a day!

I am South African and am currently looking at solar lanterns for the Sub-Saharan African region. The only reason I have not moved forward is it’s too expensive out of China
I will be very interested if to market such a product .

Your looking for a Capacitor that can do the job, try this one on for size and power density.

I just thought of a possible alternative to batteries that might just do the trick if implemented properly. I have been building beam robotics circuits for a few years and the beam pummer circuit seems plausible if you can find a large enough capacitor. A pummer circuit charges during the day and activates at night. It is designed to do it’s work for most of the night and automatically shuts off and starts charging during periods of sunlight, reactivating when the light levels drop to a predetermined level. Usually pummer circuits utilize a blinking for flashing LED but I’m sure a freshman in electrical engineering could modify the circuit to work in a constant manner or maybe a faster flash rate that can’t be detected by the human eye.
