12.12.24 test: the hypothesis was wrong, we lacked the december sunlight for the experiment to work (ironic)! Fresnel lens 350mm diameter, test à noon. the engine with a metal cylinder is correctly powered. The solar concentration is clearly higher than with the diy plaster concentrator (we can barely see on the video but the piece of wood is burning with flames in 2 seconds). Fresnel lens pros: lightweight, small, unbreakable plastic material
