Didn't know car batteries could be so useful. Wow cool pictures. Didn’t know car batteries could be so useful.

These batteries must not last more than a year being deep discharged like this. Even so throwing out a car battery every few months might be cheaper than all the kerosene if wasted in a wick lamp, brilliant use of white LED's. A good way to charge phones is to have store owners buy thousand lots of #7805 voltage regulators, these give a stable 5 volts from any power source from 6v up to 35 volts, add alligator clips and attach to batteries, vehicle power systems, or solar panels with compete safety.

Solar panels are getting more and more popular for tasks like this though. I saw people watching telly with energy from a solar panel. Anyway, the photo is not very clear but just to show it's not an exceptional situation. I prefer the flipflop hinges... http://www.flickr.com/photos/gert/3275177488/in/set-72157610922088274/ car batteries, hmmmm… Solar panels are getting more and more popular for tasks like this though.

You use what you can get. My favorite part of this is unrelated. That motorcycle fuel is stored in beer bottles. When they are empty, they will be returned to the brewery and refilled with beer.

Compact fluorescent lighting looks ridiculous in comparison. The phone charging station is eminently practical, but I cringe at the DC/AC/DC conversion losses. But then again, maybe practical trumps efficient. LED are taking over lighting, and not just in the least developed countries. Compact fluorescent lighting looks ridiculous in comparison.
