Abstract

Energy efficient cookware is provided includes a base and a wall, a linear pattern of flame guide channels connected to the base bottom. The guide channels accept a flame and guides it to the perimeter from the central region resulting efficient heat exchange; The linear channel profiles provides maximum the surface enhancement from a given plain area on the bottom to improve heat transfer while provides even heating, and mechanical strength to the cookware; The impedance to entrance of flame flow into the channels is minimized to allow easy entrance of the flame into the channels; A square base further extends the linear channel length to gain extra efficiency. A method of making the efficient cookware is provided involving welding an extruded channel base to a wall.
