Those sultry summer nights are just around the corner, so it's time to start thinking about how to save money on your electric bill and stay cool at the same time. That's where Evening Breeze blows in, cooling only you and the area where you're sleeping, without wasting energy cooling the rest of the room.

The Evening Breeze Canopi intakes air from under the bed, removes its heat using a wall-mounted unit just like any other air conditioner, and then gently distributes conditioned and dehumidified air only on the bed. It's so efficient at pointing its fresh, gentle breeze, you can leave the windows open to bring in fresh air, and still stay cool. Instead of a space heater, it's a space cooler.

Formerly sold only as an entire bed system, this new Canopi system fits on any bed. Now for the bad news: you'll save plenty of energy, but it could take years to actually save any money, because the thing costs $4,570. Here's a video showing how it works:
