Update: DIY Solar Collector from Old Satellite Dish

DIY Solar Project Takes Shape
When I wrote about Denise and Dan Rojas’ video of their DIY solar collector they're building from an old satellite dish, commenter Luke asked what they were going to use the thing for. The brief update above gives us some idea, including burning random scraps of wood, and probably more usefully, boiling up to 10 gallons of water. Given the heat coming from the half-finished version, we can't wait to see the final collector in action. The video also shows how to convert smaller dishes. Click below the fold and you’ll see another video from Denise and Dan that demonstrate the power of Fresnel lenses (remember those 10 second solar eggs?), and what they can be used for.
