One of the big inefficiencies in most home heating systems comes from the natural tendency of warm air to rise, which leads to hot ceilings and cool floors and frequent on-and-off cycling of the systems.

So why not ensure that the hot air that goes up gets recirculated downwards once again? Looks like an obvious idea, just that it had not struck anyone until now.

Bill Zelman’s Hot-Tubes, which use a tall Tyvek tube and a small fan to move the air, are designed to be low-cost, simple to install, and easy to use, and could end up saving homeowners a fair bit of energy and money every winter.

These lightweight tube fans can easily be hung almost anywhere, allowing you to recapture the warm air that you’ve already paid for.
