My march pump works good for me. I pump through 50' of 1/4" copper with no problem. As others have said, after the first 5 minutes or so, flow is less important than cooler surface area and temperature differential.

Flow rate would probably help, but temp dif is probably more important with the pump for the lower temps. My little 300 gallon pump drops the temps great once below 100. The water coming out of the output is still fairly cold so I don't see the need for increased flow for me.
I live in an apt so no garden hose for me. With my old kettle I would have to do the hot wort scuttle to my kitchen to hook it up to my faucet. Now I am using a keggle I can't do that safely so I need an alternative solution. I would love to use a march pump but I am a poor college graduate until I get my career going. I would think that I could use cold tap water until I get my temps down around 100 then throw the ice into the bucket that I am pumping water from so it isn't soo much of a waste.

Since you are using a march pump for cool temps only, there is no reason to spend the big bucks. I bought a used march pump for 10 bucks on ebay, 20 if you count shipping. Then your only cost is fittings - say 20 bucks at a hardware store and you are chillin' like a pro.

Are there any mechanical engineers here? just curious. I'm new to this stuff, and wort chillers look like heat exchangers, which is the bread-and-butter of MEs, right?

This is cool, some creative thinking going on here!

Right, wort chillers are just heat exchangers. Lots of ways to put them to use. The most efficient ones are the big plate chillers.

Have any DIY types invented some super-gonzo cooler that pushes the envelope of physics?

Isnt the idea of using a pump with a chiller so you can use say 5 gallons of water to cool your wort and not have to waste tap water? Tap water should be better conserved as it is not an unlimited resource like some think. It costs cities immense amounts of money to maintain a water supply that we can drink from and we all need to do our part to conserve it, imho.
