If you enjoy drinking beer and like the idea of solar energy, I’ve found the web page for you. It provides detailed instructions for creating a solar heating panel made entirely of old beer cans. Why use beer cans? The authors provide a list of reasons, but my favorite is “Instead of buying a sheet of aluminum for $24 at Home Depot, you get to drink $24 worth of beer.” Sounds good to me.
