It's getting cold out there this Autumn -- very cold. Before those natural gas or electricity bills start giving you financial chills, you'd be wise to watch the video above. This appears to be an ingenious way to create a very cheap solar heater you can use to heat individual rooms using a few common items you can find at a local craft store or discount bin. That, and hopefully a jar of pennies.
If you're adventurous enough to tackle this 30-minute project, let us know how it goes in the comments. The physics for this project sound completely legit, and this video almost could pass for a poor man's solar roof collector. Of wait -- it can!
Seriously, this is one 'green' way to heat up your rooms this winter as long as you have some very decent windows that have access to sunlight (preferably, full sunlight) at least four hours per day. The more sunlight exposure, the more heat.
