How much technology would be needed? Maybe an antenna, a rain sensor, and a governor? A governor and a rangefinder?

However, from a technology standpoint, enforcing the legal distances which have already been calculated by engineers to be correct as far as stopping distance, and not letting a car get pushed accelerator down when another car is in front of it, would prevent accidents.

People are really looking at autonomous driving from the individual car angle. But I haven't heard many talking about it from the perspective of technology that could be added to the road which demands control of the individual's automobile.

"As long as the contact stress between the #gasket and the mating surface < fluid pressure, the O-ring seals in the [pneumatic gas or hydraulic liquid]. What's even better: ↑ fluid pressure 🠪 ↑ contact stress—we have a positive #feedback loop, guaranteeing the seal."

@c981f1466097c77 youtu.be/u3Xiy2DVnI4 “Linear regulators are simple but inefficient. Switches can be very efficient for a particular circuit, but are hard to design.”

Why are so many components electronic now, anyway? I believe it is to do with wear and vibration. 1. a solenoid won't snap like a string would 2. a mechanical relay bounces and can wear/bend/snap

Runaway trains were a problem in the 19th century, when digital knowledge hadn't crowded out thoughts of gears and clutches and flywheels. Why didn't they use flywheels to slow down trains on long downhills?

For the case I'm most interested in [a heavy truck/lorry on a mountain decline], *you would think* that bolting a flywheel to the undercarriage and transversing that from the axle, would have already been tried.

It seems like (1) energy recapture will never be more than ¼ efficient (2) regenerative braking systems can slow down a vehicle significantly faster

The full wave rectifier is a design topologists can already write home about. The pecuniary upshot (besides "obviously less efficient") is "otherwise the capacitor costs too much". learn.adafruit.com/power-supplies…

Solenoid design—this is where I could see mathematicians make a difference in heavy industry. youtu.be/esUb7Zy5Oio You have loads of freedom to invent with complicated waveforms. Engineers check their work with an FEA, but you can't generate ideas that way.
