This was my first official experiment with my new fresnel lens. This one is a 4x3 foot spot lens salvaged from an old projection TV. To say that the temperatures at the focal point are impressive, is an understatement. Not bad for a late afternoon in November! PS - A friendly reminder, these dev...

This is the trough mirror and a Fresnel Lens set. The water was shot in with a hose to produce flash steam. Ball bearing were used as ammo. A few modifications from this learning experience and we can launch 200 yards.

This is a raw unedited video in realtime demonstrating the physics of light through a Huger Fresnel Lens. As water is added to the Fresnel side of the lens, the Focal Length triples due to water filling in the grooves of the lens. The optical quality is reduced causing the light to spread over a...

This is the same engine with a strong Fresnel Lens. The steel wool adds power to the displacer piston as the light has a good focal target INSIDE the glass chamber Dramatically increasing efficiency. This is very important as most Stirling Engine lose 50% of their heat into the surrounding air. A...
