Is the minimal steering cause of weight or is there another reason?

Edward Okeyo Obala because they are always on the edge of traction at the rear wheels.

Oh snap now I get you I thought you were talking about why the front steering mechanism and input system is usually small... But yeah if you make a slight turn you are going to flip

@@edwardokeyoobala380 Exactly. Good old Newton. That steering force has to go somewhere and it's much easier to flip it on its side than to overcome the inertia of it's forward travel.

Also, real drag cars will spin their wheels at 100 mph, and take throttle control to ride the line of max power without wheel spin.

Over in a matter of minutes? :D

Thanks for doing the calculation. Now if only there was a way to transmit power through Earth like Tesla wanted to do, we wouldn't need caps eaither

yes, i was thinking the same thing. and then how do you charge it. but then thinking about light rail or maybe even city buses. this would actually work pretty good vs having to run wires over the road or track. anyw, they are quite amazing used in the right situation.

@@jmac1099 Perhaps one could use inductive charging at stoplights and such for city busses.

You'd also have to screw around with charging the thing 180 times.

@@manipulativer we know how Tesla wanted to transmit power. With induction. It's literally how we wirelessly charge phones. And the efficiency is trash(30%) and it barely works at all over longer ranges, and that won't change. If you want to go fast with electricity take a train.

Electric engineer? Hi! ...I'd like to ask...why are there no hybrid tech in cars using supercaps instead of batteries? There's gotta be a better reason than just 'sizes', right? It would be cool to have an 'electric nitrous' system

My thoughts exactly, besides I've seen somewhere here in RU-vid an experiment in China where they installed capacitors in a bus and charge it in each bus stop

Capacitors maybe great, But let us consider the price compare to batteries. The more capacitance it has the more expensive it is compare to li-ion batteries. Plus its bulky size, you can’t just compress a high capacitance capacitor cuz it requires wider area of plate for a high capacitance or for more energy it can store.

@@kontde Modern busses, including petrol-powered ones, use flywheels to store kinetic energy. Simply put the energy from the brakes is used to power a wheel inside a vacuum chamber that can spin over 30,000 RPM. When the power is needed, the generator is reversed, and the power from the wheel is transformed into electrical energy that is sent to the wheels. It's also employed in race cars. Formula E uses flywheel energy storage, as well as some hybrid Le-mans prototypes (919 Porsche for example). F1 uses a battery system (possibly Li-ion) since its still more efficient in terms of space to energy stored, however.

The channel "Real engineering" has a great video about that. Search for "Real engineering Tesla" and you should find it. The title says something with Batteries. Tesla bought a super cap Company to use These caps for the exact same reasons you mentioned in Your comment.

ive seen a capacitor bank for race drones to use on launches

Very, very, very poor. Supercap energy density (volumetric and mass) is terrible, sadly.

The Supercaps advantage is in Power density instead of energy density

@@TheZio69 Do you need super caps for lasers or normal caps?

Don't forget about price!

@@thealienrobotanthropologist bad answer

They definitely need a dc dc converter to be useful, and generally seem to have the most usefulness when used in combination with batteries. They can take the brunt of surges, in say acceleration in an EV or for regenerative braking, while keeping the output of the battery cells within a range that promotes longer lifespan. The main problem is that they're quite expensive and heavy, from both the cells and the added need of an extra power converter.

Super Capacitors are really Cool ( :

If its a toy or a big scale model it doesn't matter in engineering...in some practicals it is made in small models and the same ideas is used in big ones

Or wireless pc mice

Just make it chargesble via usb c

Do supercaps age? A small rechargeable battery might work just as well.

@@spankmygimp now i want to learn how to wire super capacitors on my mouse just for that, a 1 minute drop on a charging port giving you a few days of usage sounds great!

@@Mike-oz4cv Yes. I think they get more charge/discharge cycles than a lithium cell, but you get less capacity so it sort of cancels out.

What do you think about supercaps in hybrid cars?

@@xXZ31t6esTXx anything that captures the energy that would normally be lost to heat via the conventional braking system has to be a good thing. So super capacitors used in a hybrid design can only increase efficiency. Its not so much the amount of energy that can be stored in caps for this application, rather the time to charge and discharge. Once a mass is moving, its much easier to keep it moving. Getting it to move from standstill is energy intensive.

Bilal Habeeb same

Bilal Habeeb boooo I liked this style more entertaining

But hes got to get them views and making an informative video tends to not perform as well, even if we nerds love it.

I don’t know who this is but I’m blocking recommendations based on this video.

habirton thanks for telling us, but literally no one cares.

How about a combo?

Scorpio then even more extremely bulky with even lower energy.

If you need capacity supercapacitors are not what you are looking for. Super capacitors are good at very high discharge rates and extremely fast recharge capability over thousands and thousands of cycles.

Isn't it just 27 times as many shown for the rc car?

Same goes with batteries. If you still need more than 10 minutes to fully charged your car and you can't bring spare batteries just like we could with gas, the tech is not mature enough, but here we are.

😉

CSIRO here in Australia developed that tech for deep cycle lead-acid batteries, intending to use it for electric cars. They were overtaken by the supremacy of Lithium batteries, AFAIK the idea never went past prototypes.

Or just use a transformer

So you could maybe do small charging strip's on highways to charge your caps while driving. And to extend range you have a regular batteries or even charge your batteries over time from the caps. But I don't know how efficient that would be

Codiac Using capacitors to charge a battery would be just buffering. Optimal efficiency would be to charge the battery directly. Capacitors are nice but their size to power makes them less practical and their cost is even more expensive than lithium batteries as they are now for less power.

DriveJapan I don’t understand the hype for supercapacitors as if they were invented yesterday or something.

amorag59 most people are not truly tech savvy, never herd of them, and it sounds like magic. Perfect recipe for flash popularity. Most people can’t tell you the difference between the various types of capacitors. Let alone the benefits of each of them. Tell someone they block dc and pass ac any watch them try to process that. Or to add fuel to their confusion tell them that electrons don’t actually flow through a capacitor. I have had people who know a bit about electronics/electricity call me a liar because they couldn’t wrap their head around that. Magic I tell you... magic!

@@drivejapan6293 Good point. As an EE I have the privledge of people smarter than me laying down the facts. But then again I see people with comments like "We could line our roads with charging coils to charge the caps as cars/buses go by" Lol yeah the same people so *eager* to fix your potholes is going to spend millions on that, suuuure. Lol doesn't take a tech sav to see that is ridiculous 😂.

You could also heat the tires with heat blankets like in f1 or with other way

Other factors: Was that wing designed correctly? (and would it matter at the kinds of speeds of an RC car?)

@@KuraIthys At that speed, I'd guess it's just weight.

It seemed okayish until they tried to turn it. Have you ever seen a dragstrip with a turn?

Seemed to crash when you let go of the accelerator.

Maybe gear down the steering for a much larger turning circle?

I'm going to start a car company and steal your idea

Elon musk wants to know your location

Tailslol they already are in multiple applications. Like the dodge eTorque

hybrids are the only way electric cars are truly feasible as sports/heavy load vehicles

Why do we need to use caps for regen and not just the Li battery? There are considerable drawbacks with supercaps: The energy density spec tells us a Li battery will usually be smaller in size, you won't find too many with high Farad rating AND high voltage tolerance, we don't want more complication with parallel/series orientations requiring balancing electronics. Caps also leak so "starting up everything", most likely won't be an option after sitting for a while.

they've done them before.

Not new.

Have you been under a rock? They've done ones with the backyard scientist, Allen Penn, Tom Stanton, Ian (forgot his user), Nielred

@@Deelan1990 your well over the rock

Deelan1990 go learn spelling

My guess is lower CoG would be the fix they'd need. Maybe some more weight in general.

@@LawrenceOakheart a bit late to answer that... But my guess is that it needs a diferential in order to give similar power inputs to the wheels even if one loses traction Then the added weight and lower CoG would make it even more stable having two motors, one for each wheel is always a challenge

OH wait, I think I get it! 2 x Time (1 hour) because the (V^2 x Farads) is divided by 2? SEE ALSO: en.wikipedia.org/wiki/Farad F = Watts x Seconds (and that's a dot product) divided by Voltage^2 ...

The equation for the capacitor energy in J is (capacitance x voltage^2)/2. So to convert it to Wh, it must be divided by 3600. So yes, the 7200 is just 3600x2

@@TomStantonEngineering This is correct, but only if you discharge them completely to 0 V. With most electronics that is not possible, so strictly speaking you would need to do the integration with the charge voltage as upper limit and cutoff voltage as lower limit. Because of that the usable energy is even lower with the caps. With batteries these simple calculations work way better, because the voltage is almost constant and the result will be pretty close without taking the discharge curve into account.

@@TomStantonEngineering Power equals energy consumption over time, P=E/t, i.e. the power is the rate of energy consumption in a given amount of time. Energy in a capacitor equals (C*U^2)/2. So how dividing the energy in a capacitor with time gives you the Wh, when the formula from the first row of my comment and in general says that P=E/t? Dividing the energy accumulated in the cap with time gives you the power that your capacitor can reach. It gives you the power that you are able to sustain/reach/develop using that particular capacitor. So, ((C*U^2)/2)/3600 gives you the power you are able to reach for every given second using that particular capacitor. Wh and J are equivalent, interchangeable. In fact, Wh are Joules and Joules are Wh. You can't divide Joules with time and say you've got Wh, because you don't have Wh, you have W. Deducing from P=E/t using measurement units, we get that 1W=1J/1s, meaning that 1 Watt equals to using one Joule of energy in one second. So, 1 Ws equals 1 Joule, one Ws is 1 Joule, 1 Joule is 1 Ws. You can't divide the Joule with time and say that it's a Wh or Ws. It's not Wh, not Ws, but it's W. So (3^2*50)/2 gives 225 Joules of energy. If you use 225 Joules of energy for the following hour you are getting power of max 0.0625 W every single second.

@@zrnjan You are so close to understanding why/how the 3600 is used, that I thought I can help you the last bit. In short, it is simply a conversion. A factor without a unit. Tom Stanton says in his reply that the initial formula is for energy of a capacitor puts out an answer in Joules. And the 3600 is used to convert the result from Joules to Wh. As you state yourself 1 J = 1 W * s. And there is 3600 s per hour. Therefore the answer in W * s needs to be divided by 3600 to have the answer in Wh. Another take on it. If you have 1 J, you have 1 W * s. But not 1 Wh. You have 1/3600 Wh = 0,00027778 Wh. The factor converts the number by a factor that fits to the conversion of units. Lastly way I can formulate it. If you have a light bulb using 60 W of power, and you let it run for 1 hour. It has used 60 Wh of energy. You end off your answer by saying that the Capacitor will output 0,0625 W every second for 1 hour. Then we can conclude that it have delivered 0,0625 Wh. Hope my (long) answer makes sense and helps you :)

@@mmazz30 I'll believe "electric dragster" when I see it. That's nearly 7.5 MEGAWatts of equivalent power lol. I'd like to see them make that power at dragster weight.

@@amorag59 Yeah. Normal car, normal fuel... Electric (or hybrid) will win. But drag cars aren't exactly normal, and petrol has a much better energy density than any battery for the moment.

@@amorag59 You DO realise that the while it's not purpose-built dragsters, that Teslas have been beating petrol cars in drag races for ages, right? It's the one form of racing they unambiguously have an advantage in. The performance package equipped model S can do 0 to 60 mph (~0-100 km/h) in 2.28 seconds, which very few internal combustion vehicles can match even if they're purpose built racers. Then there's this monster, which has been with us for a LONG time already: www.geek.com/geek-cetera/worlds-fastest-electric-car-is-a-1972-datsun-can-do-0-60-in-1-8-seconds-1416865/ Yes, that's a Datsun. Doing 0-60 in 1.8 seconds. Electric cars have a HUGE advantage in acceleration from a standing start. And I'd like to point out that an electric motor that can hit that kind of power output isn't very heavy, relatively speaking. The traction motors powering something like the german ICE-1, produce a combined total of 9,600 kw SUSTAINED output. (peak output for short periods can easily hit at least double that, if not more.) That's used to get an 800 tonne train up to 250-280 km/h And it does that using 8 traction motors... Thus each motor is built for sustained output if 1.25 megawatts. Given these motors are mounted between the wheels, which means they have to be compact and fairly light (unsprung weight is a major problem for high speed trains. The train as a whole can be heavy, but the bogies cannot.). Getting an electric motor into the multi-megawatt power output at relatively small sizes and weights isn't much of an accomplishment. Powering it off a battery however is quite a problem. Though a drag race only lasts a few seconds... The main issue is the current draw. The reason Teslas can win drag races but not longer races is because the battery management system can cope with extremely high current draws for a few minutes, but cannot sustain that output over a long period. In terms of acceleration from a standing start, an electric powertrain built for that purpose will easily leave all but the most carefully designed petrol vehicles in the dust. It's not even remotely a fair fight IF you can sort out the power supply issues... (battery current draw limitations. One of the reasons why supercapacitors hold an appeal in this context even though they'd suck for a road-going electric car.) The motors can handle it. Easily. The battery systems are where you hit a design limitation.
