I have tried to watch the video footage...It's 11 am and the Meloi family...then it freezes.I have got a mobile usb dongle connection.Why does it always freeze about 16 seconds into clip.I have tried it ten times.
Very frustrating.Why can't they have windows like most sensible people do?
Talking of ingenious use of nature instead of electricity, I saw a video recently of a British girl who developed a simple evaporation refrigerator for use in Africa.
The basic design involves two buckets, one larger than the other. Pack the base of big bucket with earth until the rim of the smaller bucket is level with the rim of the larger bucket. Now pack the sides with more earth.
Put what you want to keep cold in the small bucket, and pour lots of water on the earth packing until it's totally saturated.
As the water evaporates in the heat of the day it draws heat away from the earth, thus keeping the contents of the small bucket chilled.
The beauty of this is that it doesn't matter how filthy the water is, as it is kept away from the food in the inner bucket...
