Odd audit today at the asphalt plant.  For about half of it, we just sat around because they were so busy they didn't have people available to facilitate us.  I do get to work on one idea, though.

Check it out.  They have these big tanks that they fill with water and chemicals.  The water comes in from the city at about 66 degrees but it needs to be heated to 150ish degrees in the tank.  Presently they heat the water with steam once it's inside the tank which is inefficient because you have the sun!

One of the other dudes figures that if you set up black pipes on top of some of the tanks at the facility, they could probably preheat the water so that they don't have to run so much steam into the tanks, and hopefully cut down on their natural gas bill, which is way high.

That, my friends, is a good look into what the IAC does.  This one will be wilder than usual, though, because we have to figure out first how much it's costing them now to heat the water and how much we can heat the water via the sun.  That'll be fun...maybe.  Hard...probably.

I got home about a quarter after six from the central Oregon trip and I'm off tomorrow for Idaho and Angela Strubhar's wedding reception.  And then it's family stuff next week.
