You may want to put some screws into the length of the wall of the tumbler so that the compost doesn't just slide upon rotation of the drum. This is a quick and dirty way of snagging the organic material and forcing it to tumble. Conversely, you may want to install fins or paddles along the inside wall of the tumbler to perform the same function.
Congrats on the build! Quick question, does your pump ever get hot? And is there any concern of potential EtoH vapor reaching ingnition temp in said pump?
if you have a syringe-style printer (like the kind to lay down clay), you can wrap a resistance-wire laden silicone pad around it to heat it up and lay down the melted wax in trial and error method to determine the speed necessary to lay it down reliably.

Congratulations on making a medical device!!!! I'd like to forward this to a colleague who runs the open medicine initiative at Stanford...who is the lead/ P.I. on this project and contact info for them? Clint LeClair, MD
Congrats on the writeup! I would, however, recommend doing a thorough patent search before applying for one. Both of these technologies (desiccant wheel, pcm storage of solar heating) have been demonstrated in solar home competitions performed by uni's here in the USA.
based on that relative thought- a year ago, I converted my log splitter into a leaf compressor to make logs out of all the oak leaves. They burn with the same amount of ash as the logs, burn just as long and hot, and I don't loose the trees! Just take a short fat pipe as your template, stuff with leaves, and ram with the piston, and repeat until you get the length you wish...and voila, leaf logs!
