Was in der Diskussion etwas verloren geht, ist diese Paralleljustiz namens “Schiedsgerichte”, wodurch sich Konzerne versuchen aus der Verantwortung zu stehlen oder geltendes Recht auszuhebeln, um sich Vorteile zu verschaffen. Es sind eben diese, welche auch in Freihandelsabkommen mit den USA auch dem Rest der Welt aufgedrückt werden (Siehe dazu bspw. die Kontroverse um TTIP und CETA und das darin enthaltene Investitionschiedsverfahren).
I’d add an overlapping step sponsored by BP in 2004: “Climate Change is real, and here’s a calculator to show you, that we have nothing to do with it.”
For the uninitiated: The Carbon Footprint Calculator was introduced by BP in 2004 as what can only be described as a successful attempt to shift attention and blame to the general public.
The main problem with Hydrogen is the efficiency. If we want to get off fossil fuels, we need to talk about primary energy, not only the electricity consumed today. That alone means that we need multiple of the electric production (the physicist in me shudders at that word) of what we have today.
So instead of the finite resource of oil or gas, there’s a bottleneck in energy production and its infrastructure, which means that we need to be efficient with the energy we have. With Hydrogen, you first need energy for Hydrolysis, then cool it down and pressurize it which uses a lot of energy. And then converting it back in the fuel cell to usable electric energy is again lossy. On a good day that’s an overall efficiency of about 30% (which is around the peak efficiency of the combustion itself in modern ICEs). A good LiPo Battery (which comes with its own problems, and for industrial applications energy density is less of a problem) has a roundtrip efficiency of 98%. So you’d need triple the production infrastructure (PV, wind mills, geothermal, etc.) for your storage, if you’d do everything with H2 compared to everything with batteries.
Which means, that if there aren’t major breakthroughs, like a totally different technology (e.g. photosensitive bacteria) to produce H2 at a multiple of the efficiency of today’s tech, then H2 and E-Fuels in general have to be reserved for the applications, where energy and power density are un-negotionable (like airplanes, some construction equipment, or for some agricultural applications).
Yes these are all good and valid arguments as a bridge technology used when we can’t meet demands through other, already availabe, often better suited technologies. With the power structures today though, it often gets pushed as the ONLY future. Which is what I’m pushing back against. We should use it where it makes sense, not where it serves some particular interest group to consolidate power to the detriment of us all. I mean H2-cars? Really?
Ah ja, dies ist ein weiteres Kapitel des internationalen Rechts - insbesondere Menschenrechte - als Wahlbuffet. Man bedient sich wann und wo es gerade passt und lässt links liegen, worauf man gerade keine Lust hat. Nennt sich Rechtsstaat. \s
As an engineer I can attest that it is also useful for quick calculations and illustrations, especially at the concept stage. We also ran process “simulations” in it for fun, but of course something like SciLab would be better suited for it. The possibility to simultaneously work in the same spreadsheet was also a godsend during lock-downs.
It probably wasn’t that powertrain in the car for FP1. Usually the new engine makes in the car by FP3 or even quali. Even on normal weekends without a new engine, and especially later in the season, teams would run an “FP1 engine” on Friday to minimize mileage on a different engine for the more demanding circuits.
Generally yes, but I believe it is best done on a case by case (meaning type of sports, level and skillset) basis.
Generally on the recreational level, the differences between the sexes are much smaller than the differences within one sex. The best example that comes to mind is Tennis. Although it is physical in that it requires a lot of high-speed strength, which theoretically should be an advantage (on average) for young men, the skill difference between a man and another is far greater than that between an average man and an average woman. Go to a public court and you’ll see a non-ignorable amount of women outplaying men (if they even dare to play each other) and what’s even more baffling, older people beating younger people. On the absolute elite level though, they seem to almost play a totally different sport. Ball speed, running speed, ball spin and variety in spin on average are very different on the WTA compared to the ATP and therefore similar but different tactics and even technical styles are employed in the two. The difference within the Top 100 ATP or Top 100 WTA is much smaller than the average Top 100 WTA and average Top 100 ATP. So on that level, imho the segregation is merited.
As some others have already suggested, there might be better criteria to judge this separation on, like with weight class for martial arts. It is not always clear where that divider should be, though. As for tennis: Is it body weight or height? Maybe your fastest or average first serve? Maybe your fastest or average ground stroke? 30m Sprint time? Wherever you put that line might change the nature of the game played in that group and not even eliminate the de facto separation on sex or age, but in turn make it unattractive for some people to engage in a competition in the first place.
Which comes back to my initial statement of judging it case by case depending on the average difference between sexes and the difference within sexes.
edit: replaced gender with sex. Didn’t think of it because in my native language this distinction isn’t made.
