Well, it's more like "oh, the well uses X kwh, can't do anything about that". > Oh, and if you have teenage girls tell them that the daily shower does > not have to exceed 30 minutes/person ;-) I have two teenagers, but my son is the water worshiper. I do know that *heating* water is only a minor cost in our grand scheme of things. > I can understand that you are cautious about the point-blank > statement Not cautious - I realize I just don't know enough about this to judge. > This avoids nasty rework in case the ground split does fly into your > face. Hmmm... The AVdd and reset signals go between the grounds. I don't expect I need as much perfection in this to warrant serious investigation into noise, just a design that works "well enough" in a robust way. I suspect I'll end up just merging the ground and power planes, and providing per-chip Vdd isolation (it's just a resistor). > Well, 23MWh is huge. Unless you guys heat with electricity. Nope! Heat is half wood, half oil, with a little passive solar (windows) thown in for fun. Oh, and all that waste heat from the electricity, but it's not the primary heat. > Recording runtimes of the big motors, compressors etc. would > probably help a lot.
