This won't act as a venturi with high flow rate in the middle since the sides are not a static material.
I think this design should work fine as long as flow rate is decent. Since it doesn't have a jet plate, static pressure should be fairly low, boosting efficiency. Water is also an excellent conductor, so as long as it's flowing through the circuit at all, any "stale" water on the outer edges is still rejecting heat into the "center", this of course is assuming that the entire contact area doesn't see the same flow.
Is this thing available to order any where? There are now several designs available, but the only ones not on pre order are the EK and the Bykski. My Bykski arrives today, and I only paid 65 dollars for it. It feels like money well spent. Without it I wouldn't have a loop till the end of the month.
