SunTaste by SunOK



The SunTaste recurs to the so called “non-imaging optics“, first used in an oven in our later model, the Sun Cook. It works as a greenhouse, capturing the sun’s rays through the glass lid. In addition, solar radiation is also reflected by the external flat mirror into the cooking compartment, doubling the input of energy. The rectangular footprint reduces the need for reorientation, when compared with more squared shapes.


Inside the cooking compartment, mirrored walls act as compound-parabolic concentrators (CPC), greatly reducing the need for regular re-orientation. These concentrate all incoming solar radiation to the bottom absorbing plate, which in turn radiates heat allowing for a very homogeneous temperature to be attained. The cooking compartment’s insulation and the double glass cover minimize thermal losses and may keep food warm for some hours even after sunset. Ideal for late dinners then.

Nearly everything. The SunTaste can be used outdoors for:
  • Cooking all sorts of dishes (except frying), while keeping the food tasty and moist;
  • Dehydrating food, by keeping the door slightly open and the lid facing the Sun to generate heat but allowing air circulation.
Here are some examples:
  • Vegetable soup (120 min);
  • Pork chops (20-30 min);
  • Grilled fish (30-45 min);
  • Curry chicken (90-120 min);
  • Bean stew (2 hours);
  • Walnut cake (60-75 min);
  • Manioc puree;
  • Bread, soup, pasta, yogurts, jams and many, many more.
While indoors, it’s also very useful for:
  • Working as a retained heat oven, completing the cooking process initiated in another oven, operating like a hay cooker and saving energy in the process;
  • Making yoghurt by taking advantage of its excellent insulation and keeping both lid and door closed.

Cork is the bark of the cork oak. It is a 100% natural plant tissue with attributes that no technology has yet managed to emulate, match or exceed (read more here).

It is extracted without harming the tree nor the Environment and is fully recyclable and among its outstanding properties, the following are very suitable for our solar cookers:

  • Excellent thermal insulator (absorbs and retains heat)
  • Lightweight (50% of its volume is air)
  • Impermeable to liquids and gases
  • Elastic and compressible (it adapts to pressure and temperature, and regains its shape even after significant deformations)
  • Slow burning (it’s a fire retardant and doesn’t emit toxic gases)
  • Anti-static and anti-allergic (prevents the appearance of parasites and bacteria)


In addition, cork and its agglomerates have a very significant environmental impact:

  • Trees absorb CO2 from the atmosphere while growing their bark so our products not only avoid the emission of this gas but they result from CO2 sequestration.
  • Consumption of cork contributes to the economy of the “Montado” a unique Mediterranean bio system and one of the 35 global biodiversity sanctuaries (read more here).
