The manufacturer makes the following claims regarding their stove:
This stove uses no-cost rice husks as fuel, produces minimal smoke during cooking, and allows the user to control the amount of flame on the burner using the rotary switch. Furthermore, gasified rice husks can be converted into char which is a good material as soil conditioner due to its high water holding capacity, or ash when the burning of char is prolonged inside the reactor, which is a good refractory material.
Further details on benefits here.
It has an over 35% thermal efficiency, its operating time is 45-50 minutes (depending upon operation or rice husk type).
The manufactures specify that the stove is safe to operate but users must take precaution when working with high levels of heat.
Optional accessories are the Combo Power Box with inbuilt battery and Solar/AC Charger.
