For those of you who are down in SE Alaska, keep an eye out for a half day conference about air source heat pumps.  The event is at the Craig High School from 10am to mid afternoon next Saturday (May 6th).  Air source heat pumps operate basically like an air conditioner, only backwards.  Pulling the air from outside and running through a cycle which extracts the difference of the exterior and interior air, it can then inject heat into a room.  For marine coastal areas that have winter temperatures hovering around freezing, these units can work well in keeping homes warm.

The key to units operating cost effectively in residential homes is cheap electrical power.  In maritime SE Alaska communities where hydro might be able to provide a kilowatt for around a dime, this type of technology can efficiently provide the opportunity to basically pull your home heating, right out of the air!
