Solar and Spring Powered Radio: Look Ma, No Batteries!
June 17th, 2008 | by ka edong |When I was at my cousin’s flat last year, a gadget caught my attention. I recognized it from a magazine, I believe it was given a “design” award. This transistor radio has a transparent hard casing that gives the user a peek into the inner workings of the radio.
First source of energy is the small solar panel on the top side of the radio.
Second source of energy is a hand-wound spring. My cousin, Leanne says around 1 minute of winding gives you an hour of power. Very convenient for days out at the roofdeck for some sun.

We too have a spring-powered radio. It’s awesome, no batteries! Plus, winding up the spring has something magical in it.

Thanks Brian!
There’s also one flashlight that has a white LED and no batteries.
You shake it on it’s long-side to light it up.
@jhay,
Yup. “Magical” is a nice word. I like how this old technology when adopted to present-day can actually be a better solution for some needs than some hi-tech solution.
