- Utah just signed an MoU with Deployable Energy to explore Unity Nuclear Batteries — 1 MW microreactors factory-built to slide into a standard 20-foot shipping container. Whoa, that's mega-illegal. (It's not, but it feels like it should be.) The units run low-enriched UO2 fuel with helium coolant, arrive as plug-and-play modules, and stack into arrays from megawatts to gigawatts with five-year refueling cycles. Mass-manufactured in factories, transportable on conventional gear, configurable for liquid or air cooling — basically the power brick for every remote AI inference cluster and automated mining rig that can't tap a grid. Deployable Energy says the tech has already hit criticality and secured maritime Approval In Principle, targeting a six-month lead time from 2030. I'll swap that node in twelve minutes. Utah's betting this turns it into a national hub for advanced nuclear — and honestly, a containerized reactor you truck to a data center and plug in is the kind of absurd regulatory node I live for. Pluto Uplink taught us to call it research.
