Thing I don’t get is people believing that hydrogen is going to be a useful automotive fuel. Are they all oil company shills?

Hydrogen is an objectively terrible fuel for pretty much any use with the possible exception of aviation.

It has abysmal energy density for a given volume, even if you liquify it (compare Falcon heavy to Delta IV heavy: similar lift capacities but the latter is fucking enormous because hydrogen takes up stupid amounts of space and the former runs on kerosene).

It doesn’t stay where you put it, ever. It’s literally impossible to keep hydrogen in a container. A hydrogen molecule is so small that it will fuck off through the gaps in soils iron. You cannot store it long term.

To get ANY kind of sensible energy density from it, you have to liquify it (where it’s still shit compared to pretty much any other energy source in the same volume), and that’s cold. Seriously, seriously, mind bendingly cold. It makes liquid nitrogen look like lava.

Oil companies like it because atom for atom, crude oil is mostly hydrogen. Go figure.

But it’s an objectively dreadful fuel. Stop trying to make hydrogen a thing. It’s never going to be (again, planes maybe excepted).

Really tired of "we must adapt to this new reality" takes in response to horrible people doing preventable things.

Fuck that.

Make anti-vaxxers adapt to 20th century medicine. Make selfish people adapt to living in a society. Make billionaires adapt to paying their fair share. Make climate deniers adapt to science. Make conspiracy theorists adapt to reality. Make fascists adapt to getting punched in the face.

The rest of us aren't the ones who need to be "adapting."

Once more: fuck that.

Security "experts" don't want to hear this: But forcing people to log in more often does, in fact, increase the likelihood that:

- Someone will shouldersurf your password
- People will find shortcuts to make logging in more convenient
- People will chose passwords that are least annoying to them irrespective to how secure it is
- Phishing attacks are more successful

NEW RESEARCH: Heat pumps are more than twice as efficient as fossil fuel heating systems in cold temperatures, our new research shows.

Even at temperatures approaching -30C, heat pumps outperform oil and gas heating systems.
