Intro: 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.

    wooow. That looks like fun! I think that's amazing for using clean energy!

    Hi,

    Gravity does the job. It is a bit closer to a catenary shape like a hanging chain or how power lines curve in the center. It works with a smaller piece of plastic too.
