Project Laundry List was a New Hampshire group that encouraged the outdoor drying of clothes, "making air-drying laundry and cold-water washing acceptable and desirable as simple and effective ways to save energy," as quoted from their mission statement. It supports what is sometimes called the "right to dry".[1]
It provided information to help change laws and prevent neighborhoods, private housing developments, and apartment complexes from outlawing clothes lines because of aesthetic reasons, under the stated principle "All citizens nation-wide should have the legal right to hang out their laundry."
The organization was founded by a resident of Concord, New Hampshire, Alexander Lee, but went into hiatus after Lee moved to China in 2010 and as of 2017 does not appear to be extant.
