SMR could actually be ideal for ZFS because ZFS is based on a copy-on-write pronciple and does not write in place. However, this would require exposing the low-level properties of the disk and making ZFS aware of them.

Yes, nitrogen is very happy being N2. In fact, itâ(TM)s so happy that many nitrogen-bearing molecules want to go back to being really happy, really really fast.

How does earth soil work after it has been stripped of all organics in a high temperature kiln? Is it any better than simulated regolith?

If you run a number of growing cycles with waste recycled into the substrate and seeded with soil bacteria - does it eventually turn into âoerealâ soil?

Just like hydroelectric dams - almost all the good locations are already taken since the 70s or 80s. There arenâ(TM)t that many places where the local activity is high enough and the underground structures provide enough water to get good steam useable for geothermal. Those that were a available were developed and are dutifully doing their job of providing clean energy. Their total contribution is a couple of %.

Producing âoedryâ geothermal energy that can be deployed in many more places is still not a well-developed technology. But t s definitely getting some funding and attention.

Ice is white. Over its lifetime it could reflect much more energy back into space than the energy required to make it.

The scale is still massively impractical. Perhaps a couple or hundred nuclear-powered freezer submarines operating over 20 years might make some impact.

The proposal of sending relective aerosols into the high atmosphere above the arctic is a way more realistic method of climate engineering.

Lots of people almost never fly and would just sell their allowance.

So this is equivalent to basic income to everyone + tax on air travel to finance this basic income.

I donâ(TM)t care. I like german wheat beers like Weihenstefaner, Paulaner, and the microbrew made by a friend.

Is that the best you can come up with for global warming? Youâ(TM)ll have to try harder...

Yeah, that and the companies who don't want to do "military applications" can just do pure research. Pure, ivory-tower research... which the DoD can just pay someone else to integrate into an actual weapon system. It's not like a machine learning algorithm knows or cares to what use it's put, once it is out there.

Dumb posturing; I also wonder if these people have considered what a world dominated by Chinese and Russian military AI will look like, and what effect it would have... I am not sure it would be the best of all possible worlds, exactly.

If any USA person or company is involved in any way (investor, employee, subcontractor etc) in a launch the government of the USA considers it as something it has jurisdiction over. IIRC, international space treaties actually require signatories it to regulate such activity by their citizens.
