Lot higher then that. Lol ?? Insane prices. One of the things that always shocked me putting bikes together was common hardware prices. Grade 5 bolts and such were expensive. ?? Hard to find cheap source and still get quality.Yes parts are usually marked-up 100%.
FYI
If it was more efficient to run an engine which ran a generator to make electricity and then use that electricity to run a motor that drove the wheels then that's what manufacturers would do.
That's way less mechanically complex than making a transmission and running driveshafts and stuff.
You ever notice most car innovations came from other applications like space program, military, air planes, locomotives, and heavy industries? With exception military have spent my working life in it. Best years of our life is spent working. ??
btw there is no drive shaft in modern locomotives. ?? Mag lev trains are flat motors. hmmmm ever seen a mag lev auto?
we load tested our locomotives against the grids. Nice $30,000 screens show volts amps hp rpm fuel throttle notch high voltage ground leakages temps so on. Those 4400 hp diesel engines just turned the alternator that made the power to move things along. Then there was dynamic braking 6 figure braking forces.
Cat owns Progressive Rail which bought EMD locomotives from GM.
GE sold off their locomotive to WABTEC(westinghouse)
The tier 4 locomotives were good with fuel considering the hp. It takes a lot of fuel to feed high hp engines. You really need only enough to do the basic transportation …. That is the hard part. Just because a locomotive had 8 notches of power did not mean it should be in number 8 all the time. We also built massive hp locomotives but they destroyed the tracks. Slight grades were the test for locomotives and you’d be amazed at how slight could be a challenge. We even reconfigured the hp in the train consist and operated them remotely from leads. Draw bar forces. ??
You’d think after the moon rover that we would have maintained the edge on ev. We haven’t stepped foot on the moon in 50+ years.
I keep waiting to see EV cars have problems with grounds. They are experiencing some when attempting to charge. Loco we do not use chasdis ground except computers. Airplanes were similar. Cars have chassis grounds. ?? so if one side gets a ground for say what happens if the other side goes to ground with ev. Do the EV have chassis grounds or not? They did automotive chassis grounds to cut wire cost.
how is an ev wired ? Does it have ground detection circuits On dc buss and inverter sides? Or is this why they have been bursting into flames?
