Helen from Uganda shows how she is trialling solar bottle lights using 1.5 litre plastic water bottles as a way of lighting her dark kitchen in the daytime. She uses the bottles as light bulbs, filled with water and a little bleach, grouped in 3s over her cooking areas in her dark mud kitchen with grass roof. Techniques like solar bottle lights can reduce eye strain and the need for electric lighting where electricity is too expensive or not available. http://www.sendacow.org.uk
