Theres an mit offshoot using microwAve beams to vaporize rock in a pretty neat process that leaves a glassy and structural tunnel wall not unlike the nuclear subterrene concept from 70s. Pretty cool stuff.

In terms of production capacity and industrial capability, it is mostly there. As an example, the recently unopened nord stream pipeline produced 200,000 pipe sections with similar dimensions and mass to the Micro Modular Reactor pressure v

his got me thinking about the earth's heat flux to the surface. It comes from primordial heat and radioisotope decay of thorium and uranium. Wild that geothermal energy is really just nuclear decay energy, just like the mars RTGs. But

I work on nuclear micro reactors (specifically this one: www.usnc.com/mmr) and there is big promise here to make many reactors soon and cheap. Their size of 15 MWe is too small to fully power human civilization which requires 20 TW of

The part about the dynamo being 10x lower 500 m.y.a. compared to today suggests that the background radiation was 10x higher. They point out that lower dynamo leads to more atmospheric loss to space, thus limiting biological activity. Butth

There is long term advantage to do robotic surgery in the creation of a large learning dataset. All the inputs to the surgeon - video, audio, bio metrics - are digitized, and all the surgeon outputs like movements and actions and even the p

Interesting that IP rights on a cartoon character should last 5x longer than IP rights on a piece of technology. Why?

Better question: should we revisit the pilot requirement itself? Pilot's today are glorified autopilot observers. This is a way easier task than self-driving cars. Compared to a street, there's nothing to collide with (other than

Perhaps this is good to change things up and see what other solutions are possible to address climate change. EPA does not have the will of the people or Congress, which detracts from its powers and potential impact. EPA may not be geared t

It does not require fossil fuel heat or feedstock. So it's net 0 at least.
