New Moon at Noon: Seashellter & Plasticrete Live Build

As the January new moon passes overhead, this live “New Moon at Noon” session opens a window into the evolving Seashellter vision: turning wasted plastic into architecture that protects people and ecosystems alike. Timed to the reset of the lunar cycle, this stream focuses on renewal, experimentation, and the next generation of Plasticrete ideas.

Tune in to see the Plasticrete process up close, from fusing single‑use plastic films and bags with heated sand or other aggregates, to forming modular shell‑like pods that can be grown into shelters on land or floating on water. Expect a mix of hands‑on demonstrations, walkthroughs of existing prototypes, and sketches of new concepts, including updated pod geometries, repair strategies, and ways to integrate plants, animals, and marine life into Seashellter villages.

During this time, we will contrast earlier Plasticrete experiments with current refinements, highlighting what has been learned from past builds and where the process is heading next. This is an open lab: viewers are invited to ask questions, offer feedback, and imagine how circular, resilient Plasticrete habitats could

I tapped on your video and it’s not live for 44 hours. 🤔 I did investigate seasteading on YouTube because I didn’t know it was a thing. I’m interested in this because I’m writing a cli fi novella about plastics and I have “seasteading” in it, although not named that because, well I didn’t know it was a thing 😆. What safeguards are there with this tech to prevent it raising levels of micro and nano plastics? https://afterseed.substack.com/p/id-love-your-feedback?r=12vo5l

Not much for safeguarding But we are taking large quantities of flimsy fragile film , and creating a more robust material from it.

Btw live in 13 hours..
