Lime Casein Wall Paint - Dr. Georg Kremer, Dipl.-Chemiker, Farbmühle
Lime Casein Wall Paint

Basic recipe:
40 g Powder casein (no. 63200)
125 ml water (cold!)
33 g lime putty (no. 31800)

The weighed casein powder and the water are placed in the mortar or mixing dish, covered, and left to soak for several hours in a warm place. It is best to leave it overnight to make sure that the casein has swelled
completely and has absorbed as much water as possible. The resulting casein sludge is treated like fresh curd by hydrolyzing it with the given amount of lime (20 %). This recipe never fails to produce a good,
thick casein glue of even consistency. It has, however, the disadvantage of gelling even faster than casein glue made from fresh curd and must therefore be used to make paints or diluted as soon as possible. The
gelling procedure can be avoided by diluting with water by filling up to a total volume of 1 liter and then stirring in about 1 teaspoon of cere-stucco soap (79230) 5 minutes after adding the lime. The resulting
solution is a 4% casein-lime solution. All lime-caseins are to some extent weatherproof and therefore represent a special group among the mural
media. The walls can be ground-coated by diluting the 4 % casein-lime solution with 9 parts of water and applying this solution onto the walls.


White Lime Casein Wall Paint

1 Liter casein-lime dilution can be mixed with about 1 kg pigment, e.g. titanium white (46200) or chalk from champagne (58000) or a mixture of both. The wall paint should obtain a consistency which is easy to spread, i.e. like condensed milk. Should the paint become too thick it can be diluted again. Always use the 4 % casein-lime solution and not with pure water.
Always make a trial coat to check the bond before applying the first coating since the amount of binding agent is different for each pigment. Should the paint be too chalky, more concentrated casein-lime solution
has to be added, if it shows cracks or peeling problems the paint contains too much lime and therefore has to be diluted further and more pigment added.

It is always recommended to use pigments which are lime fast.

- Consumption on clay plaster: approx. 150 ml / m2 / coating
- Consumption on lime plaster: approx. 100 ml / m2 / coating


Colored Lime Casein Wall Paint

1 Liter casein-lime dilution can be mixed with about 1 kg pigment, e.g. earth colors or other pigments from the list of Fresco Colors. The wall paint should obtain a consistency which is easy to spread, i.e. like
condensed milk. Should the paint become too thick it can be diluted again. Always use the 4 % casein-lime solution and not with pure water.

Lime-Casein Wall Glaze Paint

Basic Recipe:
1 Part of 4 % casein-lime solution
4 Parts of water
Add between 20 and 100 g of pigment per liter of lime-casein wall glaze medium and apply with a glaze brush or with a sponge.

- Consumption on clay plaster: approx. 150 ml / m2 / coating
- Consumption on lime-casein wall paint: approx. 80 ml / m2 / coating

Water Purification
Bravo to Dean Kamen for inventing something to help humanity and the environment at once. Realizing that many of disease and afflictions of humanity are due to insufficient or polluted water, he has invented an extremely efficient machine that purifies even the most toxic water into distilled water, pure dihydrogen-monoxide.



*It is designed to supply a village with 1,000 liters/day of clean water. (Colbert Report)
*You can use any water source -- ocean, puddle, chemical waste site, hexavalent chrome, arsenic, poison, 50 gallon drum of urine. (Colbert Report)
*Vapor compression distillation is not new. Doing it in such an incredibly efficient way such that it takes only 2 percent of the power of convention distillers is new. (R&D World and Gizmodo commenter)
*The are no filters to replace, no charcoal, no anything disposable (just distillation). (Colbert Report)
*The Slingshot (as its called) can use half the waste heat (450 watts) from a sterling engine electrical generator (prototype also being designed by Kamen's company) to boil its water. (TED)
*The heat put into the water is recovered with a "counter-flow heat exchanger" and recycled to heat the next batch of water (that is part of the novel bit). (TED and Gizmodo commenter)
*Slingshot will be less then 60 lbs. (TED)
*The prototype slingshot was hand-built for $100K. The goal is to get production units down to $1,000 to $2,000. (CNN)
*The sterling engine, used as an electrical generator, can produce about 200 watts of power (it will never be more then 20 percent efficient) and 800 watts of waste heat (the waste heat that slingshot uses). TED
*Later sources say the sterling engine can generate 1 kilowatt or enough power for 70 high-efficiency light bulbs. (CNN)
*The sterling engine can run on anything that burns, propane or even cow dung. (CNN)
*The slingshot is a David and Goliath reference aimed at putting water and power back in the hands of the individuals. (AP)

If the units were reduced to the goal price of $1-2K, I would certainly invest in one for my family. With a little electricity, you could have an endless supply of clean water, and a much more attractive alternative to having giant plastic drums of water mildewing in your crawlspace for emergency preparedness.
