and it was RETARDED
Or, you could pull into a charging terminal every six miles.
The concept of a flywheel-powered bus was developed and brought to fruition during the 1940s by Oerlikon (of Switzerland), with the intention of creating an alternative to battery-electric buses for quieter, lower-frequency routes, where full overhead-wire electrification could not be justified.
Rather than carrying an internal combustion engine or batteries, or connecting to overhead powerlines, a gyrobus carries a large flywheel that is spun at up to 3,000 RPM by a "squirrel cage" motor.[SUP][1][/SUP] Power for charging the flywheel was sourced by means of three booms mounted on the vehicle's roof, which contacted charging points located as required or where appropriate (at passenger stops en route, or at terminals, for instance). To obtain tractive power, capacitors would excite the flywheel's charging motor so that it became a generator, in this way transforming the energy stored in the flywheel back into electricity. Vehicle braking was electric, and some of the energy was recycled back into the flywheel, thereby extending its range.
you have to stop regularly at a power station and spin up the flywheel, and if you run our of gravy, starting that fucker up again takes massive amounts of juice.
they handled like shit and couldnt turn (lol gyro) or stop (lol inertia). you waste a shitload of power lugging that giant flywheel around, and it is constantly losing juice to friction (lol science).
when the bearings fail, everybody dies, crushed under the Wile E. Coyote flywheel juggernaut, and in the end the whole idea was a rube goldberg failure.

I wouldn't suggest using the same flywheel tech they had back then. After all it is antiquated technology; but it shows it's possible.and it was RETARDED

Imagine having one of NASA's G2 flywheels in a car.... no bearings, magnetic levitation in a vacuum, so no air resistance either.
If there was no future in flywheel tech as a power source, at least a partial one; why would F1 cars and some of the other most technologically advanced cars in the world, Ferrari La Ferrari, Porsche 918, McLaren P1, etc., etc., all use flywheels to aid in the power, often giving up to a couple hundred hp with their KERS systems?

ha ha ha ha ha ha ha!
catching some energy during braking to use again in acceleration is NOT "generating power".
winding your engine up to 1500 rpm and dropping the clutch has the same effect as using one of your magic flywheels (the inertia of the fast moving engine and it's parts delivers a larger thrust impulse when the clutch engages)
but combustion engines deliver smooth efficient power at steady throttle cruise which electric motors or the Acme Magic Flywheel(tm) do not.
combustion engines WORK, while electic motors only have good torgue and power at acceleration, and suck donkeyballs at cruising speed.
meanwhile, flywheels are always getting slower. they cannot gain power they only lose it, and they lose it constantly whether you are using them or not.

It's collecting energy that would normally be lost. I never said it was power generation, you need stored energy to speed up the flywheel. So, another power source is obviously necessary. That other source could be anything....
Electric motors deliver the flattest torque curve, and the most torque at the lowest RPM.
Yeah pretty much. Electric motors WORK too (not sure why we're capitalizing work but o.k.) , but you are correct about the efficiency of electric motors at high speed.

Cool skateboard. lol
The faster you go, the more air resistance you encounter, and the more power it takes to overcome that force to accelerate. When you get up to 100kph and faster, it takes too much energy for electric motors to sustain that speed efficiently.
Transmissions are great. lol

Well versed on that....did you know current sport bike fairing configurations were designed to actually raise drag?
Point of the vid was really to demonstrate initial acceleration, reckon my fault for being vague.
I'm not buying into the electric being the way of the future....not that it doesn't make sense, especially if you live near nuclear power but because of the politics.......it most certainly is a thing of the past......it should be a thing of the present....seem like I remember....fuuuuck dude I want to say Joan Rivers but that's not right....some lady that used to do cameo's on scooby-doo.....I will googles that momentarily but she, in an interview remembered having an electric car....in the 20's....I remember going to the wharf and taking a tour of a really old submarine....it was electric.
imho the electric car has been dangled in front of the public like a carrot on a stick and could only be the future if the energy costs are low.....that is if charges are cheap on a cost vs mileage analysis vs whatever other fuel source.....skateboard gets 15 miles on a charge.

Except that very heavy equipment, like earth movers - oh and the latest ships tend to use them, for long periods of time at constant speeds.

Actually, it is likely that the electric car will be what comes next. As our grid goes green we will need methods of storing power, wind is intermitent, so is solar, the best way to store that energy is in the batteries of cars plugged into the grid. Most cars spend the majority of their time in a a garage anyway so it's a great way to have a mass of batteries at the ready. It also helps with transmission distances.

here in the USA we use Alternating Current, which means you have a voltage regulator and a silicon rectifier to charge your battery (the mysterious black box that is always warm when it's plugged in to the wall).
this means that the battery is hooked up with a ONE WAY gate, letting juice in, but not letting it out.
otherwise plugging your cell phone (or electric pansy-mobile) into the charger would do nothing.
the electrical grid cannot draw juice out of your battery when it wants it, nor would you want it to.
see when i plug up a battery for charging, i am PAYING for that electricity, if they could simply snatch it back whenever the wanted PG&E would have long ago figured out how to do so.
because they are cockbags.

ships use them but ships are not busses street cars or passenger vehicles.
when a freighter gets under way they will be going steadlily for days or even weeks at a time, not stopping at every corner, waiting for traffic lights or idling in bumper to bumper traffic, while their flywheel spinns away it's energy making useless frction and wearing out it's $500,000 bearings.
maybe you arent getting this but:
Flywheeel Good.
Me no hate flywheel.
it work good.
but it not magical energy source.
it not solve every engineering problem.
sometimes use other type of device when problem not have rotational solution.
sometimes need linear solution.
sometimes need angles too
circles not always best.
you like Pythagoras, always yelling about triangle
triangle also not always solution too.

electric motors get up and go from a stop very well, but once you hit your chosen cruising speed they still draw just as much juice from your battery as they do coming up from a dead stop.
conversely, combustion engines do not deliver as much torque from a dead stop, but once they hit a cruising speed they are FAR more efficient than electric motors, and you dont have to drag around 400 pounds of battery in the trunk.

Wrong again Doc. electric engines can be more than 90% efficient and even up to 98% efficient while combustion engines are 30 to 45% efficient. Heat loss and friction. Internal combustion engines have many points of friction, including the rings of each piston, the cam, the crank and the bearings. Electric only has bearings and produces far less waste heat. An internal combustion engine needs to lug gallons of water, heat exchangers, oil sumps and pumps and the engine itself.
