this temperature differential causes the air to rotate. These are temperature measurements that I took at 1.30pm, IRĭetector held about 2 inches from the glass: Prototype #3 has the same rotating air principle as used in theį-Cubed. Of the F-Cubed? - the cloth, the plastic sheeting? Reference, "100%", then prototype #3 has 67% efficiency, and #2 has 51%.Īn improvement, but not as much as I was hoping for. Or putting it another way, if the F-Cubed efficiency is the It is only a ball-park comparison, but prototype #2 136ml/hr, clothĪrea 0.466m2, and scaling that up to compare with the 1m2 F-Cubed: The F-Cubed gave 563.6ml/hr in this test: To compare with the F-Cubed distiller, which has a 1m 2 cloth area, scaling up prototype #3 will be 375.6ml/hr.

I put the distiller together, and had it ready to go about 9.25am. Haze persisted all day, however, the light intensity meter gave Morning there was haze in the sky, but still fairly bright sunlight.
