Using a clothing dryer is one of the naughtiest things most people do in their homes — well, carbon-wise, anyway.  The average machine accounts for about 6-10% of household energy use and costs about $160 a year to run.

Second Nature Design, a sustainable landscape firm based in San Francisco, created this “laundry grove” — a pair of hand-wrought recycled and powder-coated steel trees where the owners can hang out their wash to dry au naturel.

I love this witty, scuptural solution to an energy problem.  Alma Hecht, owner of Second Nature, says she she may produce the trees for retail.  I interviewed her for 3Qs, so stay tuned for more.
