Missed opportunity to name these “energon cubes”

Do you want evil robots from space? Because this is how you get evil robots from space

Would that be better or worse than the evil humans from earth that we have now? I’m honestly not sure myself.

But the evil robots are converting crude oil into exhaustfree energon cubes without license, think of the oil corps!

The real question becomes which side was actually the more evil one when you watch all the films apparently.

I only watched the cartoon when I was a kid. I never watched the movies. I’m sure Congress will be interviewing the president of Harvard to ask her opinion on the genocide of decepticons.

I'm becoming less of a hydrogen guy and more of an ammonia guy. Liquid ammonia seems easier to deal with than hydrogen gas.

It is, but a leak could kill you. So 🤷‍♂️

Same could be said for hydrogen since it's a tiny bit flammable.

Yeah, but ammonia chemically burns the eyes, lungs and skin of everyone that comes into contact with the resulting gas in a wide radius.

Yeah that's a problem. However, it might make more sense on balance if we have big nuclear power plants generating clean ammonia while off peak electric demand.

Why not clean hydrogen? Just the handling issues?

Ammonia is wayyyyyyyy easier to store and contains more hydrogen. Pity about the environmental and health dangers

You don't have to store liquid ammonia under high pressure and it has a higher energy density by volume than hydrogen. Also, ammonia is already very useful beyond energy storage, such as for fertilizer. Maybe a hybrid system is the way to go, with hydrogen for smaller consumer applications and ammonia for larger industrial ones. I don't know if there's good way to produce ammonia directly by electrolysis yet, so the ammonia might still have to be derived from hydrogen anyway.

What tech does this use? Is the hydrogen compressed or captured into a temporary sink?

This is the best summary I could come up with:


Autocar, based in Birmingham, Ala., is a 126-year-old manufacturer of Class 7 and 8 work vehicles, including garbage trucks, cement mixers, terminal tractors, and more.

The company’s Hydrotec power cubs are lightweight, GM said, which enable large payloads, excellent range, and quick refueling.

Despite the technology having been in development for decades, there are only a little more than 50 fueling stations in California, mostly clustered around Los Angeles and the Bay Area.

The East Coast is trying to get in on the action, with a handful of stations up and running, and more in the works in New York, New Jersey, Massachusetts, Connecticut, and Rhode Island.

Overcoming this challenge is important for light-duty vehicles because they often have limited size and weight capacity for fuel storage.

The hydrogen-powered generators are being sold to commercial and military customers to start out, but the automaker said it plans on offering versions for residential use in the future.

Hydrogen power is a grift. Run an extension for your damn cement mixer

There are cases where getting power to a site would be a hurdle.

There are mobile battery banks for a reason. Some handle 240 at 30 amp too.

Electrify where you can, improve renewable fuels for where you can’t
