My stash of 1lb propane bottles was getting low, so I refilled them off the tank with the little adapter thingy. It finally started to run out and it made me wonder when I exchanged the tank last.
Turns out it was in Tucson in early February. So this tank lasted about 3.5 months. I chalk this up to my experiments with contact heating, and my desire to not run propane for heat.
Speaking of which, it got below freezing again last night. I wore the electric vest, although I am worried I might damage it that way. Started off on low (5w average). Before I drifted off to sleep I put it up to medium (avg 7.5w). About 4am I woke up chilly and cranked it to high (a raging 10w!). I was a little chilly when the sun came up but not chilly enough to get out the sleeping bag or anything. I’ve been sleeping under a thin fleece throw and a Mexican serape.
The sky was crystal clear today, though, redeeming the iffy solar conditions of the past few.
