Recycling car batteries in Rural Kenya

Maina, Rhoda and little Winnie are  a typical Kenyan family who live on the outskirts of Nairobi in an area that has no electricity.

But they have solved the problem of getting the daily news

When I visited their home I was impressed that despite the lack of electricity, Maina has come up with an innovative solution and is able to keep up with whats going on and listen to his favourite Kikuyu music all day long!

Here’s a better look at the system – a second hand car battery hooked up directly to his radio

The wiring is simple

Fully charged the battery last 2 weeks. To recharge Maina has to take it to a place in town for 24 hours at a cost of Ksh 50 (about 80 cents US. If he were to  use ordinary batteries Maina would be paying several hundreds of shillings per month (15$) and creating toxic waste with their disposal (Kenya has no battery disposal system).  No wonder used batteries are in such huge demand!

And no wonder this family is smiling!

I’m wondering how much it would cost to hook up Mainas battery to a solar panel and  some lights. They currently depend on hurricane lamps.  Powered with kerosene these are not only a weak source of light but are dangerous and prone to cause fires.

Got any ideas anyone – can we charge a car battery from solar?

Car Batteries and LEDs in Mali

Matt Berg has put together a wonderful photo montage on how LEDs and 12v batteries are changing the face of connectivity and cheap lighting in Mali. Reproduced here with his permission are the images from the (large) PDF.

“The mass market solution (LED + small rechargeable battery + 1 W solar panel) that will really make a difference will be Chinese and at a price that will encourage extremely fast adoption rates.”

“Used car batteries you can see are the “power lines” in a lot of African villages that form the basis of distributed power distribution.”
