oh yeah, went grocery shopping today. my pantry seemed a tad empty.

$96 dollars total  for organic food at target and winco....yep, winco has organic food...including organic honey which doesn't have unknown additives in it to keep it from sugarizing like costco's does.

costco still has the better prices...I just wanted some variety. Target beats winco on Amy's Organic vegan soups by about 60 cents per can....but Winco has variety and is employee owned.
I haven't found Amy's Organic Vegan canned soups at Costco...guess I'll ask next time instead of assuming I really looked every where :)

Special thanks to corporate Target for making organic food affordable to those who cannot afford a costco membership! Target has the largest selection of organic vegan food of all the affordable stores (including vegan organic chocolate).

Thanks Kyle for helping me finish the question of how fast!

flat water tank:
1.5" x 42" x 37" = 2331 in^3
about 10.01gal or .0381m^3

Volumetric heat capacity of water:
4.81 MJ/Cm^3

How much energy to raise the tank's water from 42F/5.56C to 140F/60C?

4.81MJ/Cm^3 (60C-5.56C)(.0381m^3)
= 9.97Megajoules

410 watts/m^2  from sun but with losses say 328 watts/m^2 from the sun

How fast (which I tried using the Thermal Conductivity to answer
rather than the applied energy).

Why did I choose that route?  Because doing so would simultaneously tell me how fast my water would cool down (in a symetrical world).

Finally I gave in to both engineers and used the applied heat; the answer was easily found of course.

9.97Megajoules/(328J/s) = 8h 27 min

well, that aint happening.

sumin gotta change cause I want that water to do 54.4C delta T in 2 hours

I am thinking of that little SAH heating a very small volume quickly and the large room volume inna 1 hour forty.....now how to do that with water and still live :]

late morning due to beautiful morning rain...

nothing notable other than relentless progress

west plate set. those little pin knobs I put on the plate's end are not meant to bear weight. The knobs are just meant to make the seperation of the joints difficult work in the east west direction.
They work well; I fitted one end just to see how it layed and I had a heck of a time getting my west plate removed to do the other end.

...and the day ends with the east plate about to be set.

nope, I didn't photograph the east plate getting its knob pins on nor its mid point joint cut in....but it happened.
