Wouldn't you love to heat your home with free energy from the sun? There are simple, inexpensive, do-it-yourself solar projects that can reduce your heating bills.

The sun's energy can be captured by homemade solar hot-air collectors and thermosiphoning panels to provide free heat. The units direct air warmed by the sun through a window or wall opening into the adjoining room.

If you're serious about cutting your home heating bills this winter, one of these inexpensive, do-it-yourself projects will help:
