Insulative Paint

[freebeard]

The building materials store across the street doesn't have anything. Anyways...

Based on this, 80% cork particles. They do have DIY vendors. It looks like I would require 3-5 gallons. Two vendors at $16-260 for three gallons else one vendor with five gallons for $200.

A sprayer for ceiling texture is required, that's rentable.

It's photochemically reactive, and used on exterior surfaces requires a UV barrier of some kind, other wise it looks like man-made volcanic rocks at Disneyland after a while.
As with any thermal insulation, the thicker, the higher R-Factor.

Oftentimes, I wonder what I was on about. [being a conduit for truth, justice and the American Way and all] In the case of Permalink #11, the hyperlink 404's. Link rot! Dead Internet is true!

Fortunately I extracted the pertinent data.

Re; the styrocrete; I just posted NightHawkInLight's Making Infrared Cooling Paint From Grocery Store Items (w/Novel CaCO₃ Microsphere Synthesis) in the free airconditioning thread. He demonstrates filling a cylinder with two different sized spheres to make a point about densifying the slurry with different particle sizes.

Similar to the distiction between sand, silt and clay.

How To Make Roman Concrete --Corporals Corner

Instead of Portland cement you can use sea shells.

Nineveh was Jacksonville, Florida - America is the Old World
12 Oct 2022It appears that Florida is composed of mostly seashells, which is an ancient form of concrete (see coquina mix and Indian tabby). The Cherokee Bee-hive tombs in the Carolina's look very interesting too, since bees are a symbol of Judah and the promised land of milk and honey.

Everything old is new once again....

IOM3 | Making concrete from seashells
A concrete-like material made from waste seashells is being proposed by materials design company, Newtab 22 in Germany. The firm is making use of the high concentration of calcium carbonate (limestone) in these shells, creating a material named Sea Stone.

Just cook your seashells to around 1900f. Prolly an additive in Roman cement.

Refractionate the seashells in a solar furnace made of concave mirrors; then use graphite flakes and whey protien to make a graphene emendment.

Mold hexagonal tiles with beveled edges in various sizes; assemble into a hemisphere.

Might need a couple dozen acres in a low altitude desert location for enough mirrors based on what I have seen for electrical generation in addition to a tracking and aiming system.
