Introduction: Solar Water BBQ With Our Annual Water Parabola
Adding water to a super thick piece of vinyl creates a very power water lens concentrating sunlight to over 800 degrees fahrenheit. This long focal length is perfect for ground level cooking. There is also a VERY simple Dutch oven DIY out of two cast iron skillets.
Because the water is level, this only works through the summer months. This is a follow-up to a video we originated in 2008.
