Citat:
The goal of this project was to reduce the Darfuri women's need to leave the relative safety of the camp to gather firewood, which exposed them to a high risk of being beaten, raped, kidnapped, or murdered.[30][31][32] It has also significantly reduced the amount of time women spend tending open fires each day, with the results that they are healthier and they have more time to grow vegetables for their families and make handicrafts for export.[29] By 2007, the Jewish World Watch had trained 4,500 women, and had provided 10,000 solar cookers to refugees. The project has also reduced the number of foraging trips by as much as 70 percent, thus reducing the number of attacks.[33]
Men förstås också nackdelar. Längre tillagningstid ex.
Annars tycker jag biolitestove var intressant. Att man även får ut lite el för laddning av mobiltelefon osv, halverar bränsleförbrukningen, låga utsläpp. Och 129$ var rätt ok pris.
Ett till ex:
