Inquiries Here for anyone that has answers?

Only place I could find the styrofoam liner is a round 8 quart styrofoam bait container at Gander Mtn does anyone else know where we can get a round Styrofoam liner, that wouldn't have to be modified to fit the 5 gallon bucket?

Also where does a person find that 12" ?? size Model Fan?

And the Solar Panel?

I was checking into a 16" 3 Speed with a Quiet motor to use in a bedroom but that might be too big for the 5 gallon bucket

I sure could be wrong, but it seems like the frozen plastic Milk container works best since even though it could/would add a bit of humidity, it's not going to be very much due to the Insulation properties of the Styrofoam liner.

Thank you to anyone that can answer these questions please?
