BTU

Finally finished a clean sweep of the hut today...no wonder my beard isn't getting any longer - must have vacuumed up two beards worth of hair.  Nice to have all horizontal surfaces empty again, if only for a short time.

Got the shower ship shape again.  The water heated up nicely today.  From Wikipedia:  BTU is the amount of energy it takes to raise the temperature of one pound of water one degree Fahrenheit.  So today the sun (and a newly patched closed system) helped out and raised 333.6 lbs of water 44 degrees = 14,678.4 BTU's.
