Penfold 'OoO': How much money would a capacitor-based car battery save you? An often-quoted number is that hauling 100lbs around in your car adds 1% to fuel consumption. If you remove a 30lb battery then you save 0.3% of your fuel bill. If you are spending $50 per week on fuel (the average for Australian drivers), this adds up to $2600 per year. 0.3% of $2600 is $7.80 per year in reduced weight leading to better fuel economy. Capacitors can be recharged hundreds of thousands (to millions) of times, unlike lead-acid car batteries which will be dead after one (or two) thousand cycles (at the most). If you replace your lead-acid car battery every 4 years, you would have to change the equivalent capacitor-based car battery every 400–4,000 years. So, in effect, you would never need to replace it (nor would your children, or their children, or their children...). Since a car battery might cost you about $100 every four years, you are spending $25 per year on lead-acid car batteries. A capacitor-based car battery would thus save you $25 + $7.80 = $32.80 (on lead-acid battery replacement costs and in improved fuel economy) each and every year. Over the course of a 50-year driving career (20–70), you will have saved 50 * 32.80 = $1,640. If, on each anniversary of installing the capacitor-based battery, you added the $32.80 you just saved in the previous year into a bank account earning 5% interest, when you retire from driving you would have about $6,900 sitting in the account. Give the battery (and the account) to a grand-child and get them to do the same, and they would retire from driving with $85,600 in the bank. If your grand-child does the same thing, then your great-great grand-child will retire from driving, with the exact same battery, 150 years after after you built it, with $989,000 in the bank... Great-great grand-dad sure was a smart fella. Moving away from lead-acid batteries makes sound financial sense, provided you think ahead far enough.

fortyninepages: If this is possible, wouldn't it have already been marketed and sold in shops as an emergency start up battery? I know I'd buy one. Just needs a case and crocodile clips.

stonner2k: what would you have done if on Monday morning on the way to work it didn't start up?? would you have just jumped it with one of the other ones? I also take it you could carry one in the boot or trunk as you would say as a buster just encase you ever need a buster?

Jeff Evenson: 30 years ago-on a 650 BSA Thunderbolt, I got tired of changing battery's due to the vibration where I rode, so using only 1 large Capacitor with a zenior diode and it always started on one kick. What the trick here is to Use them like he does, but with the battery as that way the battery and starter will last longer due to less voltage drop on first crank.

John Wiggins: I have a new found respect for capacitors...

electronicsNmore: Impressive since the capacitor bank is rated 16.2V / 58 Farads.

Andrew Lucky: this is fake, he turned on the car with his keys at 2:43. 

Leslie Willoughby: One thing to note: He started on 10v in this video-neat but low voltage is extremely harmful to a starter. Obviously depending on the crank time, and the starter load but low voltage will actually heat up on the brush end of the starter and melt the solder out of the commutator bars. The car's computer is maintaining a memory and that is what pulls down the caps. It is usually about a 1/2 amp load-continuous. You could probably remedy that by throwing a solar cell on the dash. It gave me some ideas....

bruce kazakos: the radio does not consume that much current,but on the other hand,if you switched on the heater,or the lights,well that is another story.

Chevez E: So can I hook these up alongside my regular car battery? I have room for both and would just like to be able to start my car in -40c weather. My biggest concern is that the caps will end up discharging while i'm away as I usually let my car sit for weeks at a time. So that's where the regular battery would come in handy to keep the capacitors topped off. Solar panels arn't an option either because snow. Also, I imagine that I would need to hook this up in parallel with my battery to prevent doubling up the voltage?

jeff king: And the results of 9mth test is.....?????

Adam Colon: I'm confused what the point of replacing the 12V battery with the capacitors. You lose the consistent reliable features of the battery. Is the upside simply that it's smaller and lighter? Is it worth it?

Michael Carouth: Replacing Car Battery with Capacitors! 12V BoostPack Update ---This guy, Lasersaber, has a cool Youtube channel with lots of neat do it yourself science experiments and useful projects. Those supercapacitors are available at Amazon and such. Just put enough together to get the voltage you need--- like you would with batteries.

CogitoErgoCogitoSum: And when your car has trouble starting that one cold morning? You try starting your car a few times and your capacitors drain of all charge. Then... youre freaked.

Elizabeth Sainog: How is your capacitor array in very cold temperatures? A lot of batteries get sold where I live on the 1st cold snap like -20° to -40° celcius. Do you think that your device would have the capability to start the car in 12 hours in that tempurature providing the engine block heater was on 4 hours a head of time? How about no block heater? Do these capacitors lose more more at lower temperatures? Thanks

Brian Sinper Gx: I think its genius how you mange to put this together, noting that you have a rather small car, however different vehicles require different voltage to get a crank. Considering that different climates play a difference in how your battery react. 

TheLuismondo: Capacitors in series divide the value of 1 of them by the number of capacitors (if they are the same value) Capacitors in parallel multiply the value of 1 of them by the number of capacitors (if they are the same value) So if each one of them is 350Fs and you have 6, you can either have 2100Fs in paralel (you need them to be rated at more than 16 volts) or 58.3Fs in series.

thomas smith: hmm this a great idea for race car drivers

kirby wade: Most people don't know that the batterys sole purpose is to start the engine and run electronics when the key is in the acc and on position when the engine is off. Once the engine is running the alternator powers the vehicles radio, lights and engine control computer. The alternator also keeps the battery charged, and in this instance the capacitor bank, doesn't over charge it via a voltage regulator. Also this technology is already on the market but as a battery jump box, some have deep cycle batteries and others have capacitors which like a deep cycle battery can hold a charge for long periods of time.

lou holis: Wornder how this would work in the chevy volt & help in electric range, weight would be reduced , there is no starter in the volt just an on off switch. Might have to give it a try since GM is using a 150 year old tecnology 50# battery in a futuristic car.

John Hobson: I've been a mechanic all my life and would have never thought of something like this, I'm very impressed and for those asking what the point of it is, now that I think about it, there can be a tremendous amount of applications for something like this heck you may even be able to run your homes electrical needs and even get completely off the grid which is what I think I'm going to attempt, this has given me all kinds of ideas, THANKS !!!

Susan Chen: energy = .5 C v*v=.5 x 350 x2.7x2.7 , six capacitors series connection so C=1/6 * 350 but voltage =2.7 x 6 total energy = .5 X1/6x350x16.2x16.2=.5X350x2.7*2.7*6*6*(1/6) so energy storage is still 6 times of single capacitors, series connector capacitor reduce to 1/6 but voltage 6*6 ,

Nevets: Someone needs to strangle your rooster...

d7j6f1: a small solar charger stuck behind the rear view mirror and it`ll just keep the caps topped up so you can leave it to do its thing :):)

Ken MacMillan: What's the point of this?

jahnkeanater: All those eggs. makes me wonder if you know how to basic? lol

Miodrag Zizovic: This post have been changed due my wrong assumption about working principles of super-conductor. I apologize to video poster and others to which found my post correct, and also I want to thank Sara Hearth and oldwrench2000 who corrected me.

julian marcuzzi: THE CHICKENS DID'NT SEEM IMPRESSED

Pavle Pajic: U pozadini sve vreme se cuju kokosi i petao kukurice a lik prica o novotarijama

Tyler S: Check out the new lithium batteries. They weigh about 5 pounds and put out more power than an average car battery. And they also come with a 5 year warranty. http://www.lithiummoto.com/index.html

bill hines: Those lil' capacitors can do amazing things, especially when you combine them with something else (like your hybrid comment). That was a quick start, good job!

masso172: This is interesting, but what advantages would you say this has over a standard battery? 

skoronesa: .....And the first time you forget to turn off your headlights or music before shutting down the engine you are out of charge and sca-rewed.

emf4kv: 10:03 the alternator puts out more power than you will need because no matter what you are using that is electric, you always need more than that to be able to charge the battery. Otherwise, you will eventually end up with a dead battery. The real question is what do you have to power while the vehicle is not running. This pack is great for a car without an alarm system.

miamifiction: But how much time does the capacitors need to be fully charge again? To start the car is one thing, but to turn on the radio, the lights is another...

Richard Burns: Where the hell are you, Jurassic Park?! 

Drew Jensen: The one thing that makes my slightly skeptical is he is touching away the two posts at the same time and at various times ends of the caps. I would have believe they would discharge and give him a good jolt.

Jack Doe: It is at this point interesting to point out that if the car can start from nothing but a capacitor, then the alternator will supply the remaining power after internal combustion has occurred and the linear action of the piston has been converted to centrifugal forces by cam action and such force is then transmitted through the belts to the before mentioned power supply!, additionally, the difference in weight is massive!!!, CAPACITORS START THE CAR!!!

Llia Olsen: My question: At idle rpms, in traffic, at night, with lights on, raining, with wipers running at least half speed. Will the Alternator provide enough power to keep the caps charged under those conditions?

Ian Rivera: Do some long-term testing to see if it has any negative effects on the alternator. Also, be careful adding a lithium ion cell to that circuit since improper charge/discharge of lithium ion cells can lead to catastrophic failures (fires/explosions).

Peter Marreck: I like the part where he shamelessly features the chickens and their ambient sounds. I could almost smell the chicken poo.

David Juarez: Happy new year my friend God bless you every day

bbblahoo7: God bless! your research is answering allot of my questions. keep up the good work!

daniel bancin: BAGUSNYA BATRAINYA, BATRAI APA ITU YA??

Corey Schroedter: Curious how this would perform in a newer car, such as my 2013 Dodge Dart. I've researched into lithium batteries and was considering cap batteries also. This car has a huge amount of electronic components running on it at just about all times (contrary to what that scion probably runs). I may have to try this out just for craps n' giggles. I am tired of heavy ass batteries

Ali3nat0r: How did the car still manage to start on only 10 volts?

Terry Smart: Good Day,....How do you arrive at the caps you require??,....I have a grandson with a motor scooter who needs jump starting from time to time,..one of these would take my place!!,...but wh t would I need for 12v 4amp, with a cca of 56?? Is it possible?? Thanks,....Tez

MrHangingout: cant capacitors kill you? for now Im sticking with an old fashion 12 volt DC jump starter at least until I get some answers

Tim Lewis: Well you could by another one of those 60 watt panels and hook it to the roof!

Jamie Todd: This is bad! If what he says is true it's definitely not his fault.. People right click and misuse photos all the time. He has no control over that especially if he didn't know the photos were being used for porn. I'm sure if he would've seen his photos on that site he would've sent a cease and desist letter..This model is definitely misguided and silly if she think that she can control every image of herself that she allow to be public. I hope he wins this case.
