Maybe the "fueling" part, but not the part where the fuel dispenser gets stuck to the car.
It is.

Perhaps you should once visit a fuel station that has H2?

Or the part where you are waiting for the fuel station to re-pressurize the hydrogen gas so that it can be dispensed into your car.
No idea what that is supposed to mean. If the gasoline station has no gasoline, a truck comes and filles it up.
If a H2 station has no H2 .... yadda yadda yadda: A truck comes and filles it up.

Obviously as long as there is "fuel" it is under enough pressure to fill your car, facepalm.

It takes less time to get a full H2 tank than a gasoline tank ...

These lasers require minerals that are in short supply right now, especially rare earth metals. In spite of the name rare earth metals aren't exactly rare, but they are rather difficult to refine.
That is just nonsense.

They are rare, the lazers, because they are complex systems. You have to track the target. To kill shells you need multiple lasers targeting the same shell. The electronics use simple chips. As long as they can make phones, they have enough rare earths for what ever they want.

The lasers are in general CO2 lasers. They only use rare earth, if available, they do not need it for functionality.

The people in the USDOD are certainly working on getting lasers to the front lines but they have a shortage of materials
Nope. They lost the race when they could not deliver 30 years ago as their MIC was to expensive. Now Germany and Austria is selling them for an Apple and an Egg: the Americans do not even want them: NIH syndrome.

It takes china to make them mainstream and some angry words from an american president to push them into the US Army (the Navy has a few, but does not really want them).

They withhold services until there's blackouts, because it's more profit for them to see spot prices get high before providing power than trying to keep the grid, and the spot price, stable.
If your market regulators allow that: blame the legislation.

If a price is high at the spot market, it simply means: there is a buyer for that price.
Ordinary customers, who already paid the "overpriced" end consumer price: are not affected.
Giving them a black out is illegal in Europe (and in general technically not possible, reserve power providers would jump in and bill the guilty parties).

and they only become profitable at times of peak spot prices due to their inefficiency.
That is nonsense.
Gas turbines are extremely efficient. As efficient as a "single" heat plant can get.
Obviously combined cycle gas plants are more efficient as they use the exhaust of gas turbines to heat a boiler.

Electricity from Gas turbines is expensive: because the plant/turbine is absurd expensive. A single blade of the turbine rotors in the burning area costs as much as a german middle class car.
