Another feature for improvement is to add a 4-inch rocket mass heater under the ramp. Maybe there can be an 8-inch thick mass under the ramp so you can heat the mass, but it doesn't heat the air too much. And then when the fire is out, the mass is still something like 100 degrees and keeps pushing warm air through the system. So in the fall when you have 12 hours of daylight and 12 hours of night, then you get 24 hours of drying time.

Frankly, I think that the glass part should be steeper. I think that would help a lot.

Nails are sold by the pound, that makes sense.

should*might want to* consider their latitude, and what time of year their drying needs are greatest, to determine the angle of the glass. For Northern U.S. it does feel like it could be steeper. I think the ideal is local latitude plus the tilt of the Earth (for Winter solar gain = Lat. + 23.4 degrees (tropic of Cancer/Capricorn)).
Possibly a super-deluxe, albeit complicated, version would be adjustable tilt for maximum gain.

I like the idea of having an equation to find a desired slope. I believe there is a sweet spot that relates more to the air flow science than it does the heat gain science. I believe more slope information will be discovered when Wheaton Labs alters their design at a future ATC.
