$10 DIY Passive Solar Room Heater

Life Hacker has an excellent little instructional video posted today on a DIY solar window heater. The vid details how you can turn a couple sheets of foamboard, some pennies, some flat black spray paint, and a sheet of plexi-glass into a unit that could save you $30 to $40 dollars a month on your heating costs.
The concepts are simple, and the construction looks like it could be managed by any child old enough to be trusted with a hobby knife and spray paint. I'm thinking seriously about trying to slap one of these together in the next few days, since our new house has oil heat, and I doubt the price of heating oil is dropping this winter.

How did it work, and have you looked into passive solar heating for your hot water needs? There is a batch water heater that works well in a small greenhouse outside the home that can heat water, they say up to 120 degrees. *shrug*
