Next Generation Radioisotope Nuclear Space Propulsion in the 3-Kilowatt Range

Ultra Safe Nuclear has been funded by the Defense Innovation Unit (DIU) to demonstrate a chargeable, encapsulated nuclear radioisotope battery (called EmberCore) for propulsion and power applications in space. This ‘next-gen’ radioisotope system will be able to scale to 10x higher power levels, compared to plutonium systems, and provide more than 1 million kilowatt hours …

Nuclear Fusion Startup Zap Energy Makes Progress and Gets $160 Million

Zap Energy creating the first plasmas in their FuZE-Q prototype. They achieved Q=1 where the process of nuclear fusion inside a plasma yields more energy than was consumed to create the plasma. In 2021, Zap Energy used sheared-flow stabilization to extend the lifetime of Z-pinch plasmas at 500 kiloamps (kA) of current. Zap’s sheared-flow-stabilized Z-pinch …

China Sunway Supercomputer Team Claims 174 Trillion Parameter AI Model

A team of researchers from China used the Sunway supercomputer to train an AI model with 174 trillion parameters called ‘bagualu,’ which means “alchemist’s pot.” The AI parameters are comparable to the number of synapses (1000 trillion in the human brain). However, human synapses and AI parameters are not equivalent. In 2020, Microsoft trained a …

A Fundamental Shift: The March to a Meatless Future is Now Unstoppable

High-tech plant-based 3D printed meat is the ‘gamechanger’ we’ve been waiting for. After a run of good press and some bold predictions, the ‘alt-meat’ naysayers have begun an inevitable backlash. The Financial Times in January this year asked, “Has the Appetite for Plant-Based Meat Already Peaked?” The answer to that question – despite industry setbacks …

Lex Friedman Interviewed Robin Hanson About Grabby Aliens and Many Other Topics

Robin Hanson and his co-authors have paper and presentations that the universe will become dominated by expansionist aliens who he calls grabby aliens. There are two kinds of alien civilizations. “Quiet” aliens don’t expand or change much, and then they die. We have little data on them, and so must mostly speculate, via methods like …
