a tour of 4 outhouses

permies.com The fourth is an amazing piece of art. With some really smart engineering. It seems that the secret to having no odor is to have a large pit and to vent the pit. It also helps to separate the pee. In all four, folks were encouraged to pee outside – way from the outhouses. Sawdust is used in case there is any smell. A properly built outhouse can be better for the environment than a septic tank or a sewage treatment plant. I like these three designs much better than any of the humanure systems or composting toilets. Relevant www.permies.com www.permies.com www.permies.com www.permies.com music by Jimmy Pardo

DIY Insulating Window or Door Shutters Using Astrofoil Reflective Insulation

Bruce has worked out a DIY thermal shutter design that uses Astrofoil to provide a high R value, easily installed thermal shutter for windows or doors.

Astrofoil is similar to Reflectex, but is stiffer and holds it shape better for thermal shutters.  Both products are basically polyethylene bubble sheet with a reflective layer on each side.  While the bubble sheet is not thick enough to provide a lot of R value, the two reflective layers and the air films on each side of the foil makes for a good R value thermal shade.

Astrofoil thermal shutters in the open position.

Same shutter closed for the night.

The Astrofoil can be used with or without a frame.  The pictures above show the very nice looking DIY wood frames with Astrofoil inserts, and the picture below shows Astrofoil without a frame placed in a window.  The frameless version is made by just cutting the Astrofoil a little larger than the window frame opening and pushing it into place.

The 5 minute Astrofoil shutter — cut it out and push it into place.

All the details here…
