The Blazing Tube Solar Appliance is a trough-style solar cooking device utilizing a high efficiency solar vacuum tube to absorb the solar radiation concentrated by a non-tracking compound parabolic reflector. Even high temperature operation is achievable.
Joining the system’s solar components with a separate highly insulated round cook-box, further ensures Blazing Tube’s high temperature maintenance during cloudy intervals and even into the evening hours. Using no moving parts and constructed of metal and glass components, the BTSA has a long service life expectancy. Its unique energy conservation characteristics allow it to operate under marginal weather conditions, during which most other solar cookers fail. Normally operating at a temperature above 300°F (148.8˚C.), foods can be fried, baked and boiled throughout daylight hours, and maintained at hot serving temperatures above 160°F (71˚C) late into the evening hours.
Recent news and developments
- February 2015: A refugee woman in Burkina Faso cooks rice with a Blazing Tube solar cooker. The stove is assembled in the USA and costs around $100USD. Oliver Lompo, UNHCR Environment Officer in Burkina Faso explained the impact the stove has had. “Beforehand, refugee women had to walk several hours a day to collect firewood. Since we have a lot of sunshine, the stove allows them to cook without spending any more time on firewood collection. And, more importantly, it does not produce any smoke - people love it.” - UNCHR
