Corolla Toyota: the battery lead could recharge it again while the car on , but the one you
made could stars your engine 8 - 10 times or a little more then it will die
, because you can not recharge it with electricity or new power to stars
your car later, , but the lead one could use it more than 2 years ... the
one you made could helps some person have a battery problem for while till
he buy new one after he get salary paid ... thanks
Forensource: How many drumsticks does it get to the gallon?
minecraftkid309: These little BoostPacks are great for stuff like go-karts if they have
electric start (never saw an electric start go-kart before)
mtothem1337: This would be great for race car application or go-karts, it would save
alot of weight and you don't have any extra electronics other then the
spark plugs that you need to run.
bigbangnone: Yea, replace your big heavy Lead-Acid battery with:
2) Solar cell to keep it topped off.
4) Rain Poncho - to wear while you flag down someone to jump your dead
boost pack because of (vapor-lock) while you were in town.
5) Carry a bright blinking light. Who cares about the radio. It's a safety
hazard to stall on the freeway without lights.
christo930: I would assume you are getting a very modest increase in mileage from not
having to charge the lead-acid battery? My guess would be that it's in the
range of 2%? The problem with caps is that they tend to not hold their
charge very long. I wouldn't expect the car to start after sitting for a
xxKoldshadoWxx: God I miss fresh farm eggs, way better than store bought.
Bicycle Builder: At 8:09 is that a Lecar, in the back ground? Nice vid
Don Sanchez: Maybe an alternative to the heavy 12 v batteries we use. Watch this and his
follow up. Really some very intriguing ideas.
Colin Nutley: I'm very interested in the results you got from your experience. Any chance
of a basic diagram of how to wire up? Would like to see if I get similar
results in the UK!
Chip Wright: This is pretty interesting! I curious how much it costs to build one of
YoSpeedGo: i just wanna known how many chickens it would take to jump start my gall
darn volvo! BAHKAWK!!!
baronvillanueva: Well Done! This reminds me of the recent robo challenge that google won.
Their robot beat all others and one significant detail is that they used
capacitors instead of batteries to provide higher voltage to make the
motors of the robot stonger
O2isfree: The only disadvantage super capacitor only hold 25% as much charge to what
traditional chemical battery does but you can have like unlimited charge
that last 100 years.
Max Clauss: What we really need is a smaller traditional 1 cell battery with a dc - dc
step up to fill the caps as needed. There's enough energy in a motorcycle
battery to start a car, it just can't come out quick enough.
Yansen Haryanto: can i use it for start my computer? about 1.000W with AC DC convertr?
James Post: This will put a large strain on the alternator to run all the electrical of
the car. Modern alternators are not designed like the over sized ones of
35 years ago. It was very rare for an alternator to fail back then.
Today, its very common. The auto industry has tried to make them cheaper
by "optimally" sizing the diode pack that does the rectification. I have
had 3 alternators blow diode packs over the past 15 years. Its an
interesting video, but my guess is that long term (a few weeks), the
alternator will blow its diode pack and need replaced or repaired ($300+).
Especially if you tax it to run the headlights during night driving. Just
some cautionary thoughts.
HYDROGENTEK: I am a "Noob" when it comes to this type electronic. I ordered the new
version Caps with all the terminal at one end. Do you a schematic that
show how you solder them together. Thank you and nice Vid.
Richard C: It amazes me with all the information available on the internet so little
here is apparently know here about capacitors. They are not a replacement
for a battery. They do come in greater voltages than 2.7V. There is no
such capacitor on planet earth that is capable of holding 1 farad due to
the volume of energy that is. Capacitance is measured in micro farads,
that is .000000 places to the right of the decimal. .000001 being 1 micro
farad. Capacitors are used to stabilize voltage. They do not charge and
discharge instantly. They have five time constants that represent a
percentage of charge or discharge over time. In this case current demand
measured with the key off can be used to determine how fast discharge will
occurred based on total capacitance. Parallel capacitance is summed. At
discharge the first time constant has the greatest discharge rate simply
because the voltage is the greatest at that time. Higher voltage through
the same resistance will flow more current. Simple ohms law. Have you
considered how this may affect the charging system? An alternator has a
field coil that must be energized. The voltage regulator controls current
demand based on said field. Just how much capacitance does it require to
keep from overloading the diodes that rectify the current provided, or does
it? There are many things that come into play, not just will it start
after two days. Really, don't you think electrical engineers have enough
knowledge to figure this out?
jawtig13: Have you driven the car with the boost pack on? My concern is about the
alternator charging the boost pack and possibly over charging. Any tests?
DomManInT1: Pretty lame when people act surprised that something works or does not when
they are too lazy to do the math in advance to see if it will work or
Abdelaziz Elrashed: Ha ha ha, I like your chickens ^_^
Hewing Enterprise: Very Impressive!
cuddles6938: Is this something like the Battery Buddy which will start your car in case
the battery is totally dead it has enough juice. Or is that just a Lithium
Ion battery that holds juice in case your battery is dead from cold
Ricardo Gonzalez: what is the cost $$ to invert to deploy it?
Justin Gould: I'd love to see what would happen if you turned the fuel off and cranked
it. Would be useful to know how long it would actually turn over before
Stick0413: nothing beats fresh eggs and fresh brown eggs are even better.
brandon miller: He's got a battery hiding under there lol =) where do you get those ?
mrliberty1776ma: You should put a small solar panel on the roof of the car that way when you
go out in the morning the capacitors will stay fully charged ALL the
Kevin Roberts: adding a small cheap solar battery mainter like harbor freight sells would
probably stop the voltage drop and only add like 1/2 pound
Kimberly Lazarski: One more thought: you appear to connect the caps in series, please correct
me if I am wrong. WHY IN SERIES? That would only decrease capacity. If you
want to increase capacitance you need to install them in parallel.
Capacitors do not work like batteries - if you need to increase voltage
(when it comes to caps it's a matter of working voltage) just get a higher
tolerance cap. If you want to increase AH and CCA ratings, install the caps
in parallel. A 16V max working voltage cap should work fine because the
absolute highest you should ever see out of a non-commercial automotive
regulator is 14.7V, more typically 14.4V or less. A 20V cap might last
longer because it will theoretically run cooler, but in any case you do NOT
want to run them in series. There are reasons to run caps in series but
increasing capacity is definitely not one of them.
Also if you are wiring them in series, you want + to - to + to -, etc. on
polarized caps. Otherwise you are removing the treatment of the electrodes
and will end up destroying them. You will eventually end up with either
dead shorts or open caps. Always respect polarization on polarized
Styxx N: That's a lot of weight saved of course like most ppl have noted you cant
leave this car for more then 4-5 days but really......ppl who WORK and
commute like myself could save some money
Jason Vo: pretty damn cool
Captain Hook: This is remarkable! There's definitely a vast potential for development in
capacitor technologies. Just think of what a great positive impact this
would have on the environment
XavierBetoN: You can integrate a small 12v solar panel over the hood for infinite
stand-by time instead of 3 days.
metalmoto: If it such a great idea, and really works. Why aren't the car manufactures
Andy K: Supercapacitors have a higher self-discharge rate than lithium or lead-acid
batteries. You'll need something to keep it topped up if you don't use the
car for a couple months (it will be dead by then).
bob s: With 6 x 350F capacitors in series you end up with an effective capacity of
58.33 Farads. If the starter motor draws say 100 amps then a 1 second start
drops the capacitor voltage by slightly less than 2 volts. Fine if you have
a car that starts easily like the one in the video but if it takes 5
seconds of turning over before it starts then that capacitor is going to
minus1724: dont know if someone already told you , but the reason why you Li-po got
destroied is that you didnt have a balancer for the Li-po ;) then one of
the cells propperly got charged over 4,2V
tedtw: That's a neat experiment. However - cold weather will be a tougher test.
Cranking amps for a vehicle when temps are in the teens greatly increase,
to as much as 600 amps. Another thing I found when working super-capacitors
- is internal resistance. This is the real limiting factor for how much
current you can pull out of super-caps. Since 6 super-caps need to be
connected in series (2.5V is a typical super-cap rated voltage) total
internal resistance will be 6x that of 1 cell internal resistance. Although
it looks easy to start a vehicle with super-caps, battery cables are thick
for cranking at cold temperatures.
Capacitor inter-connect and connection wires need to be as thick as battery
cables. 12v (nominal cold cranking voltage) at 600 amps = .02 ohms
effective total starting circuit resistance. Adding just .5 ohm
interconnect resistance into this circuit represents a huge voltage drop,
lowering circuit current. Vehicles often need to be cranked longer at
frigid temperatures to start, too. This is where lead-acid cells can
provide more power.
There may also be a heat issue with hot summer days under the hood which
can affect super-caps. Super-caps are like most electronic components. 85C
(185F) is often the max. temperature for capacitors. Summer temperatures
under the hood of a vehicle can easily exceed this. This is why engine
control processors and other modules are usually located inside the
vehicle, which usually doesn't rise about 145F.
William Porter: Will the alternator see a capacitor as the same impedance/resistance as a
car battery? It seems like the biggest risk is killing the alternator.
John Elliott: Wow, Brand New Crook Battery ! Nice work ! LaserSaber : P
Max Noble: Right on. good work. How long will it crank your engine? disconnect the
ignition system and turn it over
CWR032: This would make a great portable jump pack; instead of something heavy that
takes a couple hours to charge that will only trickle-charge another
vehicle, it could be light, charged off a running car in a couple minutes
and immediately start a car with a dead battery. I'll bet a pack even half
the size of what you made could be put inline on a set of light jumper
cables and make them much more effective.
Nomoreidsleft: Great for the Canadian winters. When it gets down to -20c, lead acid
batteries will have a hard time cranking the engine. These capacitors,
don't loose power in the cold. You should patent it and start selling it.
Um, you should at least use some tie-wraps to keep it secure.
Shroom Duke: are those caps in series or parallel? coupled with a small battery pack
might be a good system. can you measure or calculate how much power those
caps can store?
So, how much for the eggs?
Where are you, can I come get some fresh eggs?
Bio Power: You want to be careful that thing doesn't short out floating around there.
Would be very spectacular if it did.
Bryan Castro: Try it with a truck
Jason Carmichael: Neat to see tiny capacitors working. I remember my 1F cap I had on my sound
system was about 4" diameter and 12" long. It was awesome, 1K amps ready at
the flip of a switch and 14.4 volts no mater what.
