I think so. At the apex of the loop gravity balances centrifugal force, Fg = Fc, when going the minimal speed necessary to get through the loop. Fg = m g, Fc = m v^2 / r. So mass m drops out of the equation.

You just have to go fast enough. The minimum speed keeping you from falling out of a circular loop is sqrt(gr), with gravitational acceleration g and loop radius r. 10m radius requires 36km/h, which might be suitable for a Jetski. Larger ships need bigger loops to physically fit, and consequently larger speeds. It's quite surprising, but a monstrous 100m radius loop needs less than 120km/h.

Der Foxconn-Ansatz ist da günstiger. Einfach Netze um die Dächer von Hochhäusern spannen.

Die Antragstellerin begehrte vor dem Amtsgericht die Feststellung, dass der nunmehrige Beschwerdeführer ihr Vater ist.

Sie mag ihn vielleicht mal "daddy" genannt haben, aber dass das Gericht das so wörtlich nimmt, geht zu weit.

Ja. Im Verkehrssektor passiert momentan nicht so viel. Tempolimit "will" laut Wissing "niemand", er reitet das tote Pferd eFuels bis zur Verwesung und blockiert damit eine entschiedene Abkehr vom Verbrennungsmotor, und bei Elektromobilität geht es momentan auch eher schleppend voran. Da könnte der Minister auch mal der deutschen Autoindustrie in den Allerwertesten treten. Die Bahn muss erstmal ihre Strecken auf Vordermann bringen, bevor wir über mehr Güterverkehr auf der Schiene reden können, das Problem hat er aber geerbt.

IIRC, the first model ate mosfets for breakfast because the photo resistor is way too slow going from illuminated to dark. That leaves the mosfet in a fairly high resistance state for an extended amount of time during which it dissipates a lot of power. You should add some kind of Schmitt trigger inverter that buffers the resistive divider and gives you a clean narrow edge to drive the mosfet gate. A 74HC14 together with a 7805 voltage regulator should give you enough output voltage to drive the mosfet. These chips cost less than a single replacement mosfet and you can drive 6 coils with them.

And all the gold for his grillz? And the NMR and FTIR machines? Those are at least more broadly useful. Still, looks like he has way too much money on his hands.
