I was hoping for a new season of Rick and Morty.

WebP and the other formats are options that the admin can enable or not. I guess it's up to @dansup@lemmy.ml for pixelfed.social.

Never post your resume or sign up for LinkedIn in the course of a job search? Never use a dating site? Never buy a domain? Never pay property taxes? Never go to court? I see your point, but never revealing your info online isn't realistic or even a choice for most people.

No.

Okay, but this application only requires 1.9MWh on board. That would be about 57kg of hydrogen. The required capacity would actually be less since the hydrogen refuel time should be significantly less than recharging a battery. Anyway, I just doubt very much that 11,900kg storage vessels and fuel cell would be required. There's simply less dead weight in a hydrogen vehicle as well as better performance and less externalities associated with battery production and disposal/recycling.

As for the efficiency of hydrogen production and delivery, it shouldn't matter. We need to produce it anyway for emissions free steel and fertilizer production. The real problem is that we don't have enough emissions free energy production, which isn't one that battery vehicles or storage facilities solve. The current paradigm is one of deficit in order to create a market and I think battery storage unfortunately facilitates that. Instead, we need to build out capacity so that there's almost always a surplus of electricity with the extra getting diverted to hydrogen production. It should be rare that the process is reversed to turn hydrogen back into electricity for the grid. That hydrogen is currently too expensive is the result of bad policy, which BEVs just reinforce.

Lol wow.

Locking my account helped me cut down my Twitter usage a lot by making it pointless to reply in most cases.

I meant apart from the hydrogen fuel costs. It's not obvious to me why the labor and maintenance costs of hydrogen powered mining vehicles wouldn't be greater than that of the battery powered versions and the attendant charging/battery swapping equipment.

Why would the operating costs be higher?

Ah you're right. Assuming an energy density of 160 Wh/kg that's still almost 12,000kg. That much hydrogen contains about 400MWh.

A 240 tonne battery? That's almost 240 tonnes less payload. They should make one that runs on hydrogen or ammonia.
