  1. So far, there’s been too much cloud cover to test it properly, though the silly thing is a couple degrees warmer at the top opening than in the rest of the room even on these cloudy days.

    I’ll probably place it initially in the south-facing bedroom (smaller space) for testing — most of the plants are in there and will love it, anyway — but it would be great if it performed well on those sunny, zero-degree days in the kitchen and beyond.

    If it works, I’ll next be looking at the designs using painted aluminum or steel cans and let the resident Boy Scout, who helped with the first one, loose on one of those models.
