Yeah, I was thinking about just building a big 16' long wedge on 4 wheels.
Roll it out in the fall, hook up to a window, and hide it away in the springtime.

Just have to worry about the local kids taking it for a joy ride down the hill...

I was thinking 2'x30' worth of panels that would act as a small fence along the back garden edge that I could carry out in winter and then store away in spring. Only issue is the 20' of ducting needed to carry the heat into the basement.

Sounds like a lot of work..

But, I've been thinking of another way to harvest some hot air..
My attic does get pretty warm when the sun hits it.. So,,
Sorry about the pic (made in parts).

There is a pretty powerful exhaust fan up there.. If I could channel that hot air
into some 3" x 4" plastic downspout, and spray it into the air intake of the Sanyo..??.

Seems like it might work..

Even if the air was only 10 or 20 degrees warmer than outdoor air temp,
it might help save some kWh and keep down the number of daytime defrost cycles.
