Homemade Peltier cooler for small DWC setup?

[SuperWeed]

I too like this idea. I just saw a video on youtube where the guy was using one to cool a cooler full of water... https://www.youtube.com/watch?v=gfmyOHHoprw

Anybody have any luck?

About how many gallons would one of these units cool, average?

I would say the cheapest way to cool a small res would be to modify a top load water dispenser, there a dime o' dozen on craigslist! Ok maybe 20 bucks but who's counting? Run a stainless steel coil through the condensor area and add a pump kinda like this guy http://benkrasnow.blogspot.com/2009/03/diy-aquarium-chiller.html

Otherwise use a 25-30 pint dehumidifier and dunk the coil into a res, and pump that res's water through another mini coil into the hydro systems res.

I have a 20 gallon res I plan to cool with the water dispenser mod, until I get my centralized modified 6300 btu AC water chiller\geothermal hybrid cooler system up and running, which will cool the 20 gal as well as 2 more 30 gallon rdwc systems. No way in hell am I gonna buy and operate like 3 different store bought chillers!
