Technology data

Name of technology Solar Cooker Panthaka
Field of the technologyMajor category:
Low carbon and energy conservation		 Sub-category:
Renewable energy
Conceivable applications Cooking heat sources in refugee camps or slum areas in developing countries
Performance 1.4 kW thermal power by sun-shine beam with the lens of 1.4 m by 1.0 m
On an average sunny day in Japan, it takes 10 minutes to boil water of 700 mL to 95 degrees centigrade.
Technical maturity About 5 units (0.3 kW - 10 kW) have already made and used in Japan.
Trying applications in Kenya
Competitive advantage Performance
Easy operation by using of plastic Fresnel lens for concentration of sun beam

Installation and operational cost
¥100,000 / unit for installation
It costs nothing for operation. It does not need any utility.

Identification of competitive technology
There are various solar cookers by concave (parabola) mirrors. Comparing with them, advantages are as follows,
- easy to chase the direction of the sun,
- easy to bring it around,
- easy to maintain, and
- long life time.
Conceivable risk As we do not have sufficient production capability for mass production, this may be a conceivable risk. However, given that this equipment consists of ordinary steel beams and plastic lens processed on the surface (Fresnel lens), this conceivable risk can be managed.
Information on patent related to this technology No.2006-261778(Japan)
