The Oyapika and Karupika are parabolic cookers with two pivots that allow them to be turned towards the sun: one allows rotation and the other controls the angle of parabola´s elevation. It is is a high potency cooker as it is able to boil one liter of water in 12 minutes. It can be folded for easy transportation and can be assembled in 12 minutes. The Oyapika uses a black recipient of 16 cm, which allows it to reach temperatures of 345 °C (653 °F).
- Diameter: 130 cm focal length: 34cm (from the deepest part of the parabola)
