UBI is needed for power redistribution more than wealth redistribution. Sure, one good reason is the employment displacement from robotics/ai. But a robot tax is far inferior to general income taxes. Beyond your examples, pipes and wires into your home are automation. Machines with human operators are automation as well.

Even if you were to only tax the robot users, what about those who get rich from building yachts for the robot users?

China has a big lead in robotics because nearly all manufacturing is done there. That is there massive competitive advantage in EVs as an example. As a national competitiveness, and consumer prices, measure, incentivizing people to go collect their water from a nearby river, and heating wood from nearby trees, and otherwise committing to full employment through less automated processes, is a massive decline in standard of living.

UBI does let you create your own job. Sales and design will always be needed, even if design is inputs into an AI prompt. Without the disempowerment of warmongering rulership, AI will serve the disinformation and murder needs of that rulership. UBI/freedom dividends funded by taxes on extreme income is the path to make the winners pay for human sustainability instead of human extermination.

Solar deployments around mines can be far enough from the dusty areas. Today, tanks could bring a bunch of briefcase solar panels and when the tank is not moving and firing, its not that dusty. Cleaning is pretty easy for 20-50 panels too.

Fuel cells are the actual technology that require special designs to deal with dust.

First, the capitol/Reichstagg will be set on fire, and radical left democrat enemies within will have to be exterminated from power. Then everything else will happen.

For sure, field charging of tanks should be through DC. But H2 is the solution for energy abundance that is 100% renewables based. To have enough energy every day from renewables needs surpluses on most days, and H2 production is the best use of those surpluses because it is transportable/exportable energy that happens to be cheaper than electric transmission.

It will. Including for military applications, H2 can be produced more securely and distributed from energy independent renewables than from large refineries blown up the first day of war, that also require import supply chains.

Dust is indeed an issue for fuel cells. It is a solved issue with air filters though. FCEVs brag about making the air cleaner than without them. Industrial equipment in ultra dusty environments also work on FCs. It does require regular filter changes compared to BEV though. An industrial equipment alternative is an FC setup away from the dusty environment to recharge batteries overnight and during breaks.

H2 is much safer than gasoline. Gasoline with explode as a bomb. A leak will make everything around it super flamable. An H2 tank that both is ruptured and on fire will shoot a flare into the air, instead of blowing up and killing everyone in the vehicle.

It is less so. Also safer if tank ruptured.

energy density of lithium batteries is higher than for hydrogen storage.

opposite is true by a large margin. You'd still want a hybrid power train, and a charging from solar or BEV option never hurts, but H2's advantage is quick refueling with battery charging on the go.

Drones also seem to be good anti-tank and anti-ship weapons.

H2 tanks are safer than diesel. It would make a superior tank to diesel in most ways. Quiet, electronics power, portable solar charging in forward position, H2 production in solar rear stations. In war, having all of your large oil refineries and port handling blown up the first day is common, and decentralized and portable H2 production is an important asset.

ROK while leading on H2, is way behind on both solar transition projects/roadpath and have abandoned solar technology themselves. Government does serve its industrial champions but also serves US master. US wants to subjugate colonies to its NG. Industrial champion needs clean energy independence.

Trump is better at this than Musk...

It will be a beautiful necessary. Everyone will love the carnage. We will destroy America bigly. Like never before. The radical left democrats will hate it, but it will be glorious. Trust me.
