Desimination / Demonstration of Swosthee in Karnataka

Traditional cooking stoves have a low thermal efficiency of around 15%. From the early days the Council has been striving to provide Karnataka's house wife with a low cost alternative stove which would cook at higher efficiencies and would not demand drastic changes in cooking practices. Efforts in this direction resulted in Astra Ole, a three pan smokeless stove which can be constructed using locally available materials. Its efficiency is around 40% and nearly 2 lakh such stoves are now in use in Karnataka.
From extensive field and regular feed back it was noticed that this stove had two inherent features :

1. It is not portable, is constructed in situ;

2. All the three pans had to be used to achieve the high efficiency claimed.
