Marx290 - GREAT find!
This is incredible and will lead to a vast array of small, highly efficient cooling (or heating) devices. Imagine several of these "daisy chained" (or in parallel) so that...

Jeff, would a more extensive evaporator tube provide a better match for this particular sized scroll compressor? The point was made a couple times by Memphis that the water table is within feet of...

AC, here is a post where you estimate 15,000 BTU/hr coming from the hole if only the bottom half is in water. Memphis said he has water up to within 6 feet of the surface, so perhaps 15,000 -...

AC, I think you had the same thoughts on the efficiency being better than 2.5 or so. Rather than my math, here are your calculations on COP . . . (copied from your post)
CALCULATE COP

Why is the COP so low? I would have though with an virtually infinite "sink" (expansion in cold highly conductive water) that a COP in the 4-5 range would be expected. There are no lossy heat plate...

Memphis - why would you go to a LARGER cap tube and MORE length? Flow resistance is mostly by reductions in diameter (thinner cap tube) and a longer tube. Or do you mean a thinner cap tube and more...
