The Table-Type Solar Cooker was designed by Hideo Oguri (Haru) living in Japan. He presented the prototype at CONSOLFOOD 2023. It incorporates a parabolic reflector mounted under a table top work surface. Hideo comments that this design is better suited to lower angles of the sun, which are more typical in Japan, than traditional parabolic designs. These lower sun angles can also be the cause of reflected damaging glare into the eyes and surface burns on the hands using other parabolic designs. The user is positioned safely behind the reflector, with the focus directed away from the user.
The parabolic reflector is cut out as a segmented element using a computer-assisted design program. The cooker also incorporates a dual-axis tracking system to follow the sun while cooking, a combination of light sensors and actuators.
As of July 2023, Hideo plans to continue to refine the design, test its cooking potential, and develop a larger version. Once satisfied, he will offer the design and construction instructions as open-source.
