The Heliac Solar Cooker fresnel lens concentrates solar energy onto a mirror, which refocusses it up to the bottom of the cooktop. - Photo credit: Heliac

Heliac is a company located in Høsholm, Denmark. They produce polymer foil solar concentrators for medium size utility installations. They have developed a process to create a clear film with a profile that mimics the shape of traditional fresnel lens for a fraction of the cost.

They realized this technology would also be useful in creating a solar cooker design. The company claims this prototype is capable of boiling a liter of water in ten minutes. Having a simple framework, the company wishes others to build their own frames and use their material for the lens. They offer the design of the framework shown in photos as open source, and encourage interested parties to explore other possibilities.
