If I could pay in USD rite now I would. Its hard to come off BTC now when I wont break even in BTC. I do agree with what your saying here though this has been an awesome project that I have kept a close eye on for some time. I just wish I got in when they where still accepting paypal.
Also what I know about fans from the experience I have with HVAC, fans are more effective when pulling rather then pushing. But Im not sure that applies when its an open system since I am used to pulling through closed ducts. Although when setting up a passivise intake I always pull air through the room.
