Using snow to see heat transfer

In these photos, you can see the heat transfer happening through a number of roofs in my neighborhood. In a wintery time like we have now, the snow acts as an indicator of your insulation. If you have a full roof of snow, then you’re well insulated. If you have spots of bare roof surrounded by snow, then inside the house is an area where it’s uninsulated, or poorly insulated. If your roof doesn’t hold the snow at all, then it’s time to look at your attic insulation. Sunny, South facing roofs will naturally clear faster on clear days, due to the input of solar energy.

There’s plenty of bad found-object and “junk” sculpture in the world. I know because I made most of it myself. But Jud Turner, whose skeletal “Bio-Cycle” made some waves when we posted about it last year, does it right. He’s recently posted a bunch of new work to his website, e.g. the awesome mecha-trilobite shown above.
