Here's the second version of the homemade classical spectrograph. Resolution wise I'm pleased, it has demonstrated an R value of 6600 or better on the Sun near the H-alpha line. The final product checks in at 6.5+ pounds however, a bit excessive to hang on the end of my telescopes. Back to the drawing board, and experiment with some other materials. As they say, the third attempt is usually successful!!

This is a revamped version of the Heart House featured in "The Hand Sculpted House." Note the bale-cob hybrid construction; the surface of a bale is visible just below the blue tarp on the left.
This technique makes for walls that have a way higher R value (the walls are highly insulative rather than depending so much on thermal mass of cob).
As noted in most literature about cob, the building feels much larger once inside.

This photo was taken on October 21st, at about 5:00 pm in my backyard, in Naperville, IL. Pictured here, is a Pinus strobus tree, more commonly referred to as an eastern white pine tree. These trees are native to eastern North American and are particularly concentrated in areas around the Great Lakes. As this plant is classified as a pine tree, it is a K selected species, as are many pine trees. This means that they produce few offspring that each has a higher chance for survival compared to if they had many offspring, which would each have a lower chance for survival. This increase in survival rate is so important to a species as it can promote increased reproduction. This low number of offspring is what causes the species to not be classified as r selected, as they have low r values for growth rate. These are species which typically reach close to their carrying capacity, as referred to by the “K selected” species in their description. P. strobus focuses energy more on being a strong competitor in more crowded environments, rather than putting energy towards producing more offspring. This energy allocation also allows them to invest more in each individual offspring which then allows them to increase their fitness through their matured offspring.

A windcatcher (Persian: بادگیر Bâdgir, Arabic: بارجيل Baarjiil) is a traditional Persian architectural device used for many centuries to create natural ventilation in buildings. It is not known who first invented the windcatcher, but it still can be seen in many countries today. Windcatchers come in various designs, such as the uni-directional, bi-directional, and multi-directional.Background
Central Iran has a very large day-night temperature difference, ranging from cool to extremely hot, and the air tends to be very dry all day long. Most buildings are constructed of very thick ceramics with extremely high insulation values. Furthermore, towns centered on desert oases tend to be packed very closely together with high walls and ceilings relative to Western architecture, maximizing shade at ground level. The heat of direct sunlight is minimized with small windows that do not face the sun.Function

The windcatcher functions on several principles:
First, a windcatcher is capped and has several directional ports at the top (Traditionally four). By closing all but the one facing away from the incoming wind, air is drawn upwards using the Coanda effect, similar to how opening the one facing the wind would push air down the shaft. This generates significant cooling ventilation within the structure below, but is not enough to bring the temperature below ambient alone - it would simply draw hot air in through any cracks or windows in the structure below.
Therefore, the key to generating frigid temperatures seems to be that there are very few cracks at the base of the thick structure below, but there is a significant air gap above the qanat. A qanat has quite a lot of water inside, because there are frequent well-like reservoirs along its path. Completely shaded from the sun, a qanat also aggregates the cold, sinking air of the night, which is then trapped within, unable to rise up to the less dense surface air. A windcatcher, however, can create a pressure gradient which sucks at least a small amount of air upwards through a house. This cool, dry night air, being pulled over a long passage of water, evaporates some of it and is cooled down further.
Finally, in a windless environment or waterless house, a windcatcher functions as a stack effect aggregator of hot air. It creates a pressure gradient which allows less dense hot air to travel upwards and escape out the top. This is also compounded significantly by the day-night cycle mentioned above, trapping cool air below. The temperature in such an environment can't drop below the nightly low temperature. These last two functions have gained some ground in Western architecture, and there are several commercial products using the name windcatcher.
When coupled with thick adobe that exhibits high heat transmission resistance qualities (R-value), the windcatcher is able to chill lower level spaces in mosques and houses (e.g. shabestan) in the middle of the day to frigid temperatures.
So effective has been the windcatcher in Persian architecture that it has been routinely used as a refrigerating device (yakhchal) for ages. Many traditional water reservoirs (ab anbars) are built with windcatchers that are capable of storing water at near freezing temperatures for months in summer. High humidity environments destroy the evaporative cooling effect enjoyed in the dry conditions seen on the Iranian plateau; Hence the ubiquitous use of these devices in drier areas such as Yazd, Kashan, Nain, and Bam. This is especially visible in ab anbars that use windcatchers.
A small windcatcher (badgir) is called a "shish-khan" in traditional Persian architecture. Shish-khans can still be seen on top of ab anbars in Qazvin, and other northern cities in Iran. These seem to be more designed as a pure ventilating device, as opposed to temperature regulators, as their larger cousins in the central deserts of Iran are.
Tapered InsulFoam is cut from the same high-quality stock as our flat InsulFoam products, and meets or exceeds the requirements of ASTM C578, Standard Specification for Rigid, Cellular Polystyrene Thermal Insulation. Tapered panels were used for increasing slope for additional drainage and offers a long-term, stable R-Value and has excellent dimensional stability, compressive strength and water resistant properties.
