Hacking Okapi 2.i: Secrets Revealed
Welcome to Okapi Systems: Make the Next Generation Proud!
I am building a Huge solar heater. How big a fan will Okapi run?
Why are you pushing the heat out at floor level? No one else seems to be doing this.
Isn't it bad for the Fan with the hot air blowing through it?
Isn't it going against the "natural force of convection" to blow the heat down and out near the floor-level?
Can I use a PV Panel to operate my Okapi 2.i System? How many watts should it be?
Can I simply connect the Okapi System directly up to a PV (Photovoltaic) Panel?
Top Secret
WHY are you moving the air from the Ceiling to the Floor? It seems backwards!
When connecting Okapi to a PV Panel and Battery system, what kind of battery should I get?
