Solar Concentrator - Solar Concentrator boils water

Here is a solar concentrator project I am playing with. Using strips cut from reflective cardboard (2" strips) I am able to boil water in seconds. This is not the most reflective material to use. In fact the more reflective material you use the more powerful it will be. See GreenPowerScience channel to see how Dan and his wife made one of these and used it to make steam to drive a small steam engine that drove an electrical generator to produce electricity. www.youtube.com
