On, Over, In and Out

Ah, another beautiful day (25 degrees (Fahrenheit) in the Northwoods allowed Marc and his solar crew up on the roof to insulate pipes and install the DC motor drive. This will derive energy from the sun to pump the liquid through the pipes in the panel downstairs to the heat storage device.

Inside, where it's toasty warm the varnishing crew is hard at work. (NOTE: Fingernails intact and remain unharmed.)
And just where's Emma? Waiting, waiting waiting. Oh, by the way, the garage door is up.
