How to measure performance.
If a large solar cooker and a small solar cooker both raise the temperature of a liter of water the same amount over the same time period - are they equal in performance? 18.104.22.168 14:56, April 28, 2014 (UTC)
- When I raised the question I had the notion that the more sun you collect, the more you should be able to heat your water in a given amount of time. Picture a large magnifyng glass vs a small. So I thought it would be accurate to "weight" performance based on the amoung of insolated area. For example, if I have 1 square meter of insolated area and another cooker with 2 square meters of insolated area. And each increased the water temperature by 50 degrees in one hour, then the one square meter would have a temperature increase of 50 degrees per square meter and the 2 meter cooker would have a temperature increase of 25 degrees per square meter of insolation.

Anyone have experience with borosiliacte glass vs. soda lime glass? Pyrex and Anchor Hocking are tempered soda lime. Simax is true borosilicate. Which transmits the full spectrum of light best??22.214.171.124 18:37, December 14, 2014 (UTC)
