The Heat Project

Posted on December 3, 2013 by occulist

this is less than a saturated solution, but yet enough to be able to remain liquid to minus 30 F. If I were to be using such heat storage inside a “regular” heated structure that was not expected to get below 60 degrees F, I would add significantly more calcium Chloride to achieve a solution of Calcium Chloride hexahydrate Continue reading →

The foil will act as a reflector and as a radiant barrier. For best results, you may want to tip the box slightly towards the sun, but you will also want to put a wedge under the pot you are heating so it remains level. You can cut the box slightly taller, and cut the glass to a dimension that leaves just a little bit of the box around the edge to allow more light in, but you reach a point where the top starts to shade part of the solar box oven. The flap will serve as a reflector, so you want to use a narrow prop to hold reflector at optimum angle Continue reading →

Some notes on Passive Solar Design

Posted on December 7, 2012 by occulist

I think at this point early on, I should explain a few concepts to always be kept in mind with passive solar projects in general. I will tend to use as a reference point my area in the Northern hemisphere, … Continue reading →

While I do have a fair amount of Sodium Chloride, I decided to go with Calcium Chloride because of it’s use for extra weight in tires of various agricultural equipment. Sodium Chloride in a saturated solution does not achieve the desired freezing point depression I wanted. I aimed for something at about minus 30 to minus 35 Farenheight. Continue reading →
