you can directly pressurize from a turbine motor and pneumatic motors have some of the best efficiency in the world.. that is why air tools are so lightweight and cheap and easy to use

also if compressed air is so dangerous then why arent there more accidents killing scuba divers.. most scuba deaths are from drowning or the bends.. tanks are sturdy as hell and the valve system specifically proteccs against catastrophic failure

eletricc motors are gay

you dont have to use electricc

what are fly wheels?? what is lower cost?? what are biofuels??

all forms of energy storage are useless for transportation by themselves except for golf karts.. they are SUPPOSED to be paired with a RENEWABLE CARBON NEUTRAL ENERGY DENSE fuel like ALGAE BIODIESEL

compressed air and fly wheels are a million times objectively better and more practical for that purpose

batteries are so toxic they cant even be recycled economically.. meanwhile you 3d print a tank or machine a fly wheel and that's as good or at least half as good and you dont have to invade afghanistan or do business with venezuela as a bonus

How about you're only looking at one aspect of a flywheel energy storage system and ignoring all the others, and also unless you can show me on a graph authored by a credible source comparison of that to electric storage, then you're just spouting baseless nonsense?

Anyone wishing to know the FACTS about flywheel energy storage should read this article, which covers it very nicely:
>https://en.wikipedia.org/wiki/Flywheel_energy_storage
You should also note these two sections:
>https://en.wikipedia.org/wiki/Flywheel_energy_storage#Energy_storage_efficiency
This system is only viable under very specific conditions, i.e. frictionless bearings and in a total vacuum. Not terribly practical in a common ground vehicle nor likely very cost-effective.
>https://en.wikipedia.org/wiki/Flywheel_energy_storage#Comparison_to_electric_batteries
Might not be practical physically for any ground car due to size and shape constraints, and also centripedal force effects on the vehicles' handling.

Also add to all of the above the fact that you have to convert electrical energy to mechanical energy to spin the flywheel up, and you then also have to convert stored mechanical energy back to electric energy to supply electric drive motors with power. The losses in such a system are enormous and cancel out any so-called 'advantage' of flywheel storage. Furthermore the losses in a purely mechanical system would likewise be enormous, even with frictionless bearings everywhere.

People without an engineering background should probably not be advocating for technologies they do not understand without first educating themselves (as much as they can, LOL) on the realities of the aforementioned systems.
>>
>'flywheel storage'
>'compressed air storage'

Here's a common-sense fact for you all:
If these technologies were so wonderful, don't you think all the big automobile manufacturers would be mass-producing them and there'd be one sitting in every driveway?

Randos on 4chan with little-to-no education clearly and objectively should not be second-guessing teams of research scientists and teams of senior-level design engineers employed by large corporations who have the resources to fund projects of this magnitude. Likewise, trolls should restrict themselves to posting bait threads on subjects they are capable of understanding sufficiently such that they can successfully twist the facts enough to enrage people successfully; as-is I must judge this thread to be a dismal failure as bait since the OP has failed to understand the subject sufficiently to have the ring of credibility on the subject.

>For energy storage, materials with high strength and low density are desirable. For this reason, composite materials are frequently used in advanced flywheels. The strength-to-density ratio of a material can be expressed in Wh/kg (or Nm/kg); values greater than 400 Wh/kg can be achieved by certain composite materials.

The best most expensive and toxic lithium battery sourced from the blood and sweat of niggers mining conflict minerals with their bear ass only are capable of 200wh/kg.. so flywheels btfo your cuc.k liberal bootlicking authoritarian dick sucking ass at 50 percent effeciency.. that's what's called a satisfactory margin!

>This system is only viable under very specific conditions, i.e. frictionless bearings
not for short term energy storage.. that's why RACE CARS USE THEM.. and i said early on that fully rechargeable cars/bikes are gay af because CARBON NEUTRAL BIOFUEL has an energy density 5-10 times greater than anything fully rechargeable. RECHARGEABLE ENERGY STORAGE IS ONLY USEFUL FOR COMPENSATING FOR TUBRINE SPOOL TIMES AND RECOUPING BRAKING ENERGY! Unless youre a gay dicksucking liberal that complains about "asthma" even though particulates and even NOx can be captured by catalysts or filters.

This thing spends energy to keep the vessel steady. You can't use it for storage. Well, you can, but it's going to be extremely inefficient. If you want to preserve the energy, you'll probably need to put the whole thing on a 2-axis gimbals, or something.

Flywheels can have different designs. Depending on your goals you can optimize one thing or the other, but not all of them.
Yep, you get 400 wh/kg, but it's a bit pointless if you can only store the energy for two minutes and the total energy turnaround is going to be <20%.
On the other hand, gyros on Gravity Probe B have a velocity decay rate of ~37% per 2,300 years but it's incredibly hard to spin them up or extract the stored energy. Also, you'll need to constantly supply power for cryogenics and electrostatic levitation. But yeah, anything's possible in anime world with no cuc.k liberal laws physics.

k that's why they dont use flywheels in f1.. oh that's right they do?

there shouldnt even be e-bikes or pneu bikes because SMALL MOTORCYCLES should be allowed on bike paths with the limiting factors being speed and size instead of what form the energy is in.. bureaucracy isnt rational

the point is that IF you need a small energy reservoir to recoup braking energy and cover for turbine spool times then it's best to use a COMBINATION with compressed air and flywheels being SUPERIOR and more ECONOMICAL and less centralized

so motorcycles are completely useless in your mind?? Dont you wanna ride a motorcycle on bike paths so cars cant hit you?

youre the one who is useless.. fucking troll go to reddit or /pol/

The idea of regenerative braking on a bike is pretty good, however this approach is rather heavy, ineffient and can only store verry little energy.
It would get more interesting to use a small compressor driven by one of your wheels to pressurise your frame-tubes and use the energy stored in your frame-tubes to power a pneumatic motor.
The pneumatic motor and compressor could be the same unit, if build as a piston-compressor/expander with variable valve-timing.

This would still be horribly inefficient, but since it adds verry little weight and uses energy that would otherwise be wasted, it could be usefull, especialy in the mountains or city-riding.

How would a bike with a tiny compressor and valves weight 100 lbs?
At maximum it would add like 500g for an early prototype.

compressed air won't get any better through research due to physical limitations, batteries continue to pull away in energy/efficiency and there's plenty more ground to be gained

When decoupled from the rotating wheel via a clutch there would be no additional friction.

I was building my first electrical vehicle at the age of 8, YouTube didn't exist back then.

Go scream at the neighborhood kids to get off your lawn, grandpa, and stay off 4chan, you're not relevant anymore.

Don't you get it? You're FAT and WEAK and SLOW and OLD and are going to die, soon, which is why you fight so hard for a 'bicycle' that does all the work for you. You should just call the short bus that all the other senior citizens use and get around with that, and leave the bikes to the young, healthy, strong people who can actually ride a real bike.

I outlclimb E-bikes and can sprint 60 km/h.

Ok, I'm slow in the flats I can't keep 40 km/h for more than 3 km in the flats without drafting.

Yea, 20 is totaly old.

Technicly regenerative braking would still be energy produced by me.

comic book reading and convention going girls probably wouldn't like that kind of bike because it isn't aesthetic. Steampunk, probably but better add more brass fittings to be sure.

Cyberpunk girls are the patrician's choice and would prefer the ghetto DIY ebike with exposed wires and uncovered circuits over a steamcuck bike

Flywheels are great. A pound or two of weight only hurts when accelerating, but the stored energy easily negates that penalty.
Shoving air into a random frame tube would be suboptimal because that's really low volume and you're dealing with loss when converting between kinetic and pneumatic energy.
The ability to put energy into the flywheel by pedaling while coasting the crank->rear wheel drive would be pretty useful.

Most casual bicycles aren't very engineered for weight optimization, so a 2 pound flywheel could be offset by shaving weight elsewhere.

I'm hoping battery technology follows the same curve CPUs did with Moore's law and that we'll see extended ranges. Perhaps pneumatics could serve as an intermediary for a pedal assist drivetrain. Inverters are probably best for high torque applications which I believe should be steered away from due to how it can ravage the lifespan of batteries.

Rolling your eyes, closing the thread, and ignoring it as the useless bait it actually is.
