I just checked out the Aqua Ark website. I’ve never seen anybody mention a floating foundation before as a solution to flooding. Interesting idea.
The best technical information I’ve found so far on food server stuff comes from Tim Savas’s personal website (see sidebar link on Tim’s Media Lab page) and the design files on github (see openag-electrical, openag-mechanical, and openag_hw_scripts). Beyond what’s on Tim’s site, and the pictures @Webb.Peter took of the old food server being disassembled, I’m not aware of any existing documentation about food server stuff.
The new hardware designs on OpenAg’s github are based on custom PCBs that they appear to hand-solder with SMT gear and a microscope (based on Caleb’s Instagram). I’d characterize what they’re doing as early stage research prototypes, but it looks like their intent with this latest iteration is to move more towards hardware that could be mass produced.
On the software side, I’ve talked to Rob a couple times by email. They’re hoping to release some beta software and documentation some time this summer. But, based on the size of their team and the amount of work to be done, I’m not sure what will happen. It seems like they don’t have enough people to both actively pursue their research projects and also engage in outside communication about what they’re doing (see Update from OpenAg - Please Read).
You could try reaching out to @Caleb, but he seems to be extremely busy with travel and speaking engagements. You might also try @openag or @hildreth. Perhaps you could arrange to visit the OpenAg lab at MIT.
Also, are you aware of the N55 collective? Aqua Ark reminds me of their work. See N55’s wikipedia page and website (check out the “manuals” page for stuff about hydroponics and farming).
