The e360 course required different sensors for each lab, so we tweaked the 2-part logger with 3D printed rails holding mini breadboards to provide this flexibility.

Not surprising to anyone who regularly uses a lot of bridging in their print...but an impressive level of software control that I "think" could be replicated 'really slowly' on a consumer 3d printer within the limits of the gantry / head geometry (?)

The printing of Daedalus Pavilion, a next-gen 3D-printed structure by Aibuild in collaboration with Arup Engineers.

Built with KUKA robots, powered by Artificial Intelligence, and printed from 48 biodegradable components, this 5m-scale installation demonstrates how AI and robotics are redefining architectural fabrication.

Manganese / Bismuth magnets are far more heat resistant than Iron Nitride magnets. So might be better than iron nitride for EV motors?

Sadly, while they are very strong, it looks like Iron Nitride magnets cant take the heat required for EV motors..

I wonder if you could you drive these mechanical light generators with a piezo?

Peak Energy building America's First Sodium-Ion (pyro-phosphate) Grid Storage factory in California
- expected to begin shipments in Q1 2027, with 1.5 years of production capacity already sold
- passively cooled so no moving parts to fail

Energy Dome and Google are building a 23 MW / 200 MWh CO2 battery in Ireland, online 2028. CO2 can be compressed to liquid at ambient temps without cryogenics. Roundtrip efficiency should approach pumped hydro's 80% with a low LCOS of only $50-60 per MWh.

An interesting review of cooling methods:
https://t.co/rpfjLgJJXh
“LEDs are not just simple electricity-to-light converters, they are actually heat pumps.” A related method involves shining lasers at materials that re-emit at higher energies by drawing heat from the lattice.

Just how pure is that direct air harvested water? Is it clean enough for chip fabs? https://t.co/w7OjHNS4fh

Atoco is suggesting that Direct Air Capture is a way to dramatically reduce the water resources used by data centers. It's an interesting idea...

p53 is altered in ~40-50% of all cancers. Targeting only cells with bad p53 transcriptions could potentially be a way to target all of them with the same treatment.
