The Blazing Tube Solar Appliance 

Converting families, accustomed to conventional cooking methods, into solar cooking adherents, demands minimal disruption of normal food preparation activities. Being able to cook the same traditional foods, within the same timeframe, in a user friendly manner, are essential attributes of a successfully acultured solar cooking system. 

The Blazing Tube Solar Appliance (BTSA) has the capability of meeting all these criteria, owing to it’s advanced design.  Utilizing a high efficiency solar vacuum tube to absorb the solar radiation concentrated by a non-tracking compound parabolic reflector, high temperature operation is achieved.

Update from March 2015:

An exciting breakthrough in solar cooker design is now incorporated in every BlazingTube system.  

Intermittent solar conditions in many regions have led to a new backup option for users of BlazingTube cookers worldwide.  Essentially, a unique hybrid BlazingTube now permits users to employ the sun exclusively, or when weather is too cloudy, the ability to add heat energy from solid fuels simultaneously.  

This new BlazingTube is equipped with a rocket wood burner (and can also utilize gas burners), that gives a greater degree of reliability for the user, insuring fully cooked food everyday.  

BlazingTube can normally operate fully on sunlight alone, yet can instantly call upon the rocket stove as backup if sunlight is terminated by rain or extreme clouds.  Overall, it is estimated that the BlazingTube system will achieve up to a 90% solar fraction annually.  

The rocket stove is an efficient and smoke-free backup device, which provides for the remaining 10% of heat input.

Overall, the BlazingTube solar cooking systems can function in three distinct modes:

  • solar heat alone
  • hybrid operating with solar and wood heat simultaneously, and
  • wood backup alone.  (In extreme multi-day rain episodes).
Please note: that many of the pictures on this website are from the improved, handmade prototypes in different stages. Through feedback from the field-testing, the original design is continously improved, making the BTSA lighter and smaller, without compromising efficiency. This will reduce production cost and transportation expenses, by making the BTSA more versatile and easier to use.

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 degrees F (148.8˚C.), foods can be fried, baked and boiled throughout daylight hours, and maintained at hot serving temperatures above 160 degrees F (71˚C) late into the evening hours.
