Summertime Survivalist Solar Water Grill

This is a 43" diameter water parabola lens that can reach in excess of 1,000f  The water lens is running at about 80% of maximum power. The water needs to be distilled, rain or  R/O for maximum power. I used well water to demonstrate that it will work with groundwater. The popcorn was filmed with a  Casio EXILIM Pro EX-F1.
