Haidinger's brush: the unknown sense "I can see it particularly clearly in the twilight when I stare at the zenith; the whole sky seems to be covered by a network, as it were, and everywhere I look I see this characteristic pattern. It is very pleasing to be able to determine the direction of polarization without an instrument in this way, an even obtain an estimate of its degree" Minnaert, Light and Color in the Outdoors The eyes of men (AND women) are not designed to distinguish between different types of polarization, contrary to insects, cephalopods, many amphibians, fish, and other animals, for which nature possesses a different class of "colors" (but even common colors do not mean the same to everyone). However, a small quirk in the structure of the human eye gives us (by accident) the ability to tell apart different states of polarization. Thanks to this small aberration or "defect" of the eye we are not completely polarization-blind.

I Love Cob! ∞ Construction of a Rocket Stove View photos here » I experimented with the plans that Ianto Evans and Leslie Jackson prescribed in the first draft of ‘Rocket Stoves to Heat Cob Buildings: How to Build a Super Efficient Wood Fired Heater‘. I gotta tell you that it didn’t sink in the first time I read it. I understood it in principle, but it just seemed counter intuitive.

DIY Super Efficient Chest Fridge Hack Chest fridge Using vertical doors in refrigeration devices is an act against the Nature of Cold Air. Understanding and cooperating with Nature rather than acting against it leads to much better efficiency. My chest fridge (Vestfrost freezer turned into a fridge) consumes about 0.1 kWh a day. It works only about 2 minutes per hour. At all other times it is perfectly quiet and consumes no power whatsoever.

All for just a few quid? Amazing low-tech harvester collects water from even the driest of air Even in places where there’s a severe lack of water, there’s one thing every place has. Air. And even in the most arid of climes, there’s moisture in the air, even if it’s not enough to be felt on your skin. So there’s water everywhere, it’s just a matter of getting to it, and that’s what Edward Linnacre did with his brilliantly simple low tech air harvester called the Airdrop. With a deceptively modest design, Airdrop filters hot environmental air through a turbine, feeding it through a copper tubing system—with copper wool to maximize surface area—and into the earth where it cools and releases moisture.
