You need to define an ethical framework first. Different strengths and weaknesses. Different good and evil.
Most fire codes require hardwire or non replaceable battery nowadays. Supposed to reduce the amount of homes with dead battery smoke alarms I think. Also ensures the sensor still works.
Microblogging I can understand this being some sort of reasonable response. Discussion forums, however...
I never got into quake 2 multiplayer and I was old enough for it. Quake then half life team fortress for me.
I don't particularly care about your or his internet spats or attempt to control the all important narrative on lemmy. You are the one giving him rent free space in your brain and on your keyboard though.
He thinks he's getting bot downvoted, but there's actually people invested enough to stalk him. Cute.
You can't keep liquid hydrogen by pressure alone and even as a liquid it's volume density it's very low compared to other liquids.
You'd need huge cryogenic tanks due to the volume density of hydrogen over kerosene. Good for rockets that you can jettison tanks from, but less so for planes. I just don't see it ever being practical for aviation over just creating our own hydrocarbons out of something else. Either catalyst based or otherwise. That's potentially carbon neutral as well.
Edit: my comment, but with numbers https://pubs.aip.org/physicstoday/article/74/9/11/928294/Hydrogen-as-an-aviation-fuel It's not a problem with how heavy the fuel would be or just how much space they'd take. It's how heavy the damn tanks would need to be and how much of the aircraft would be devoted to them on long distance flights.
Not very. The entire back end of that machine is a giant lead block.
Would've been fine if he was doing that while riding high off of VC funding. You can try to pivot to new features that way. He's riding on bank debt that needs to be serviced, however. That means he needs to be both profitable and somehow develop a service that will capture market share. It's not going to happen.
