- Electron-beam induced crystallization was proposed as a route to atomically precise manufacturing, capable of producing flat work pieces or microfluidic channels but likely limited to 2-D or layered structures rather than complex 3-D forms.

- IBM’s 1990 STM-based manipulation of individual Xenon atoms and Zyvex’s later attempt to scale this into additive silicon manufacturing were cited as historical precedents for atomically precise fabrication, with Zyvex’s program now reportedly discontinued.

- Polymer capacitive micromachined ultrasound transducers (polyCMUTs) were highlighted as a low-cost alternative to piezoelectric crystals for ultrasound imaging, with a recent Nature Microsystems & Nanoengineering paper providing technical details.

- Participants brainstormed grafting plants onto fully artificial, non-biological stems that deliver water, nutrients, and photosynthates, potentially decoupling fruit production from leaf photosynthesis and increasing agricultural yield per acre.

- The feasibility of injecting extra sugars into plant vasculature and using girdling to redirect all photosynthates to a single fruit was discussed as a method for growing exceptionally large produce.

- Hobbyist thorium extraction from granite for small nuclear batteries was questioned, followed by debunking of “thorium plasma battery” claims and a pivot to aluminum-air batteries for long-endurance drones.

- Bitcoin Core 0.15.x–0.16.2 contained a critical inflation bug allowing silent double-spending and supply inflation; the flaw was patched in the emergency 0.16.3 release and discussed as a real-world example of “breaking Bitcoin.”
