In 1882, Philip Diehl ripped out a sewing machine motor, rigged it up, and called it a ceiling fan. We've come a long way since then, but these ingenious fixtures are still one of the cheapest ways to cool a room. The Westinghouse Comet fan, backed by a lifetime warranty, boasts a powerful steel motor designed to boost airflow efficiency, reducing electricity use and slashing your utility bill. The fan's sleek pewter finish and frosted glass fixture complete the modern twist on an old classic. Available on Amazon; $115 and free shipping.
