Efficiency is the standard red herring of the battery crowd - if efficiency was the prime motivation, we would all be driving bicycles and SUV or sportscars would not exist.
What are your other metrics? It’s an electric drivetrain with all advantages, but with the range of a gasoline car. Refueling cNG or LNG is standard in Europe, LH2 works just fine.
Google “burning Tesla” for that ridiculous take on why batteries would be inherently safe.
Main news for me here is that this is (still?) considered newsworthy in Germany.
At top US universities, I’ve been threatened with deportation, yelled at, prevented from going to faculty job interviews, credit to my work removed, papers highjacked and my name removed after I developed the initial idea and the break-thru analysis, etc.
There is no way out: you’re relying on supporting letters of reference from your advisors at least until you’re tenured. Your advisor doesn’t like you? Congrats, he can easily destroy your career before it even started.
A sonic boom is not necessary when moving faster than sound, the Busemann biplane resolves that completely.
There's been considerable work on sonic boom mitigation for many decades. Boom's long nose, flat underside, top engine, small wingspan delta wings are all designs expected to mitigate a sonic boom. Let's see if it works in practice.
From personal experience: in Nature Communications the handling editor and editor in chief absolutely do intervene, in my example to suppress a proper lit review that would have revealed the paper under review as much less innovative than claimed.
That's - not how that works. I suggest you look at any fluid data `riding' that border. "Super compressed" and "ideal gas" are mutually exclusive. "Equilibrium" has even less to do with any of that.
That's got nothing to do with some fluid behaving like an ideal gas or not. Also, except for very low pressures, vapor does not behave like an ideal gas.
You may have missed it in the heat of the moment, but the invasion and the war are already in full swing - by Russia. No matter what you decide, the war and the invasion are already there.
See, and people like you put words in other people’s mouths, are unable to understand and follow a conversation and then conclude that the whole world is against them. But that’s not a problem because they just want to hear themselves. It’s just annoying for everybody else.
That's what I mean. I can see you are frustrated by downvotes and suspect this big anti-Russian conspiracy - but did it occur to you that people would respond differently if you actually read what threads are about rather than just spamming your talking points everywhere? Case in point: here, we talked about whether DDoSing is an escalation to an ongoing invasion or not.
With a world population of 7.9 bio, global COVID deaths of 4.55 mio, a U.S. population of 328.2 mio, and U.S. COVID deaths of 661 k, the U.S. has ~4.4% of the world population, yet >14% of the COVID deaths.
Even if the U.S. had managed to simply reach the average of the world of 0.058% mortality, i.e. competing against such beacons of healthcare and wealth as the Congo, the U.S. outcome would have been a mere 190k, i.e. 470k souls saved.
Unless you're suggesting that U.S. Americans are somehow inherently inferior to people in other countries, or that the health care system is the world's worst, one would think that the differences will lie in policy and different measures would have changed the outcome.
I'll leave it as an exercise to you to draw a fairer comparison, maybe by comparing to OECD countries rather than all of them.
Astounding, how generous you are with other people's lives. Dogmatism is overlooking the data and holding on to your misbelief. You will know more about that than I do, I am afraid.
Wow, what kind of work do you do if you are unable to ever act without having 110% of the information? You can't be building anything, that's for sure.
Well you made it abundantly clear that the mere prospect of contributing to saving hundreds of thousands of lives means nothing to you, so I’m wondering what your motivation is to continue spreading your propaganda.
