Still another Northland business hopes to benefit from the same tax credit program that promotes the installation of energy-efficient windows.

But this upstart business doesn't deal in glass. Rather, it produces a patent-pending system called Solar Choice Blinds.

Invented by Keith McKinzie of Two Harbors,the system looks much like a common set of vertical blinds, but it's actually a special heat-absorbing metal film sandwiched in plastic. Air enters the blinds at the bottom and is heated as it rises through a baffle, usually exiting the top at a heat of 108 to 110 degrees Fahrenheit in daylight conditions.

Placed in a sunny location, the blinds can reduce energy consumption by 10 percent to 30 percent, McKinzie claims.
