The Solar Death Ray Video


Solar Death Ray ( Tek-THink) This guy ( Ray, no wait that cant be right ) narrates the video which shows how to make a water based solar thermal focus device ( known as an aqua lens ) that will quickly light wood on fire. This will be very useful if I find myself on an episode of ” Naked and Afraid”.

The solar water lens that he builds is almost 30 inches in diameter  and use free solar energy.It delivers a very large powerful focal point that is only useful around noon in the summertime when the sun is directly overhead. The material is crystal clear vinyl shower curtain. This lens concentrates about 500 watts of solar heat energy to a focal point of 1 inch optimal with a 3-6 inch scatter.
