Which does not mean the deflection of the moving air is playing no role. But the vortexes is something I can nicely show in my lectures.

to the emergence of vortexes and the conservation of angular momentum. I was surprised that with all the complex explanations in the article this never came up

I‘m really surprised that some people question the general validity of Bernoulli. I think the lower static pressure of faster moving air is well established. Another thing is its application to airplanes. There is however a good explanation for the faster movement above the wing, which is linked

U.a. weil ich selbst skeptisch bin, habe ich ja die Frage gestellt, ob irgendwo jemand schon mal mehr Details zur in Aussicht gestellten Technologie gesehen hat. Hat aber offenbar niemand, inklusive Sie. Die Nanopartikel sind ja nur im "Schutzlack". Dass könnte eine übliche Solgelbeschichtung sein.

Das war genau meine Frage, ob das eine Phantasietechnologie ist, oder ob Mercedes irgendwas Reales in der Hinterhand hat. Bezahlbarkeit scheint bei der Studie ja nicht der Hauptgedanke gewesen zu sein.

But for sure, in the past solar in cars has been used to keep the air conditioning running, while the car is parked in the sun, which could apply to all cars, but might be even less sensible from an ecological standpoint

12000 km is somewhat the upper limit in serious calculations. 8m2 area with 20% efficiency would be 1.6 kWp and could yield 1800 kWh hours in one year in very sunny climate (considering the fact that you will never get good illumination of all panels) divided by 15 kWh/100 km should yield 12000 km

Eine Stadt die Klimaschutz ernst nimmt, dürfte auch eine lebenswertere Stadt sein, von besserer Luft bis lokaler Wertschöpfung. Kann Ich verstehen, dass man das früher haben möchte.
