In this video we explore new methods of making cutting edge radiative sky cooling paint with common grocery and hardware store items. This paint when properly applied can allow for clean, electricity free air conditioning to several degrees below ambient air temperature in direct sunlight.

NightHawkInLight's super CaCO₃ micro-sphere pigment recipe:
Sodium Carbonate (washing soda) ......... 20g dissolved in 200 mL water
Calcium Chloride (painter's desiccant) ... 10g dissolved in 100 mL water
Citric Acid (used for canning) .................. 3g dissolved in 30 mL water
1. Combine Calcium Chloride and Citric Acid solutions into one container.
2. Adjust the temperature of the liquids to be between 10-20°C (50-70°F).
3. Pour Calcium Chloride/Citric Acid solution into mixer and begin stirring.
4. Pour the Sodium Carbonate solution into the mixer and begin a timer.
5. Allow solution to mix for 1 minute.
6. Turn off mixer and pour the liquid into a separate container.
7. Wash the mixer with vinegar and water to prepare for the next batch.
***Make 3 total batches following steps 1-7, each time allowing the solution to mix for 1
minute. To save time you can make large quantities of the starting solutions all at once,
chill all of it to 10-20°C, and then measure out enough for individual batches by volume
just prior to mixing.
8. Make a fourth batch, mixing for an increased time of 5 minutes.
***Optional: Make a fifth batch at 1/3 scale, mixing for an increased time of 8-10 minutes.
9. Allow 20-60 minutes for the pigment to settle out of all batches.
10. Pour the water off the top of the settled pigment and refill containers with water.
11. Repeat settling and pouring off water 1-2 more times.
12. Cut a rectangular opening in the bottom of a disposable bread tin.
13. Line the tin with paper towel and a sheet of white printer paper.
14. Pour the pigment solutions into the tin, using the paper as a filter.
15. Pour extra distilled water over the pigment to wash it.
16. Once filtered, place the whole tin into an oven to dry at 100°C (212°F).
17. Collect pigment, breaking up clumps in a blender if needed.
