Hey all,

Those of you who have been around for a while probably are somewhat familiar with my operation at this point.  For those of you who are not, here are the broad strokes:

I run 25+- miners in 3 different locations, pushing a total of 23,000 MH/s.  All 3 locations are on standard 110v outlets with 20 amp breakers.  This has been great so far, aside from the occasional breaker tripping.  At this point, I am running up against the limits of what I can comfortably and feasibly fit in the space I have access to.  Temperatures are becoming a problem (thought not bad at all), but more importantly I am pretty much maxed out on power draw. 

This has led me to start negotiating a lease on some commercial space (holy shit is is cheap still!), where I plan on moving some miners, and also adding others in a high efficiency set-up.  This is where the bounty comes in!

What I need instruction/help/assistance with:

-Some discussion on 110v vs 220v power.  I have limited knowledge here, and would love a good paragraph or two on advantages, ease of implementation, pitfalls, etc.

-Phase 3 power discussion.  A lot of the listings I looked at had this as a feature....I do not want to research this, and would rather pay a bounty for someone to sum it up with common English. 

-AC cooling.  For those of you working in enclosed spaces....I realize it is almost impossible to cool a sizable farm on AC alone without venting the waste heat.  With venting, how much AC power would one need to properly cool a 15-20 GH/s installation?  Square footage would be around 800. 


I might add more later, and increase the bounty accordingly. 

Also, I realize this info is available all over the forum, but I do not have the time to go crawl through all the topics and sift out the good stuff. 

THANKS!!!
