I have another lead I'm going to try on getting coal.
NM also went more than a week with overcast skys, I didn't even think that was possible.
Longest I had seen before that was 3 or 4 days.

also, phase change wax could significantly reduce the volume you need to store. I've yet to look into price on that stuff, so no idea what it costs.
Actually daox did some calculations on this and it only reduces size by around 20%. It would be easier and cheaper just to build a water system 20% bigger.
