Latest Patents
One of his latest inventions is an insulated building component. This innovative design features two concrete halves with an insulating layer interposed between them. The insulation layer is crafted from a material that possesses excellent compression strength, preventing direct contact between the top and bottom halves. The component's surfaces are designed to be parallel or perpendicular to each other, resembling standard building blocks. Additionally, mated walls extend between the top and bottom surfaces, angled to prevent vertical movement of the halves. The sloped facing surfaces and outer edges of the walls work together to minimize lateral movement, while the insulation layer effectively reduces thermal conductivity.
Another significant patent is the solar heating wall, which incorporates a water pipe circulation system. This system consists of multiple separate tubes arranged in a vertical plane at the center of the wall. The wall is constructed within a frame filled with a thermal reservoir material, such as concrete, providing additional support through cross supports. A pressure relief valve is included to adapt the solar wall for use with city water systems, enhancing its practicality for various applications.
