Ken MacMillan: What's the point of this?
Patrick Bonneville: 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!
Adam Keith: how are you recharging them? Im guessing the alternator would blow these
ThinkingBetter: It's a great shame that people don't do the basic calculations of the
energy involved in so many experiments like these. Car batteries are needed
because they provide much more energy headroom for ensuring the extra
energy needed to maintain power to the alarm system, remote lock when the
car is parked and for starting an engine in freezing weather.
Lorne Thomas: Interesting.
Any thoughts on this?
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
bhstone1: How are you able to engage a starter and turn over an engine with only 10V
DC? Most starters won't engage unless you have at least 12V DC.
Oliver Whinnett: I don't get it. What's the point in this?
patrick donegan: How long will the charge hold for?
One day a week driving?
leerman22: Would the current leak even though the car is off? I leave my gps plugged
in and the capacitors wouldn't be enough. Maybe if I add an "Emergency
Booster" button to my car for the winter that engages the capacitors only
when I need the extra amps to start in the winter.
cmares5858: A mini boost pack would be great to have in the trunk as an emergency
HardWayLearnt: At 0:40 how did you not get electrocuted when you touched both terminals?
Paul Handley: This is a hoax. There wouldn't be enough current for long enough to start a
car. You can fool some of the people some of the time, but you can't fool
ALL the people ALL the time!
ProgPalace: You wear the same clothes everyday? :)
Ff Geoff: I don't pretend to know whether boost capacitors could make the traditional
car battery obsolete. All I know is that undamped voltage spikes can
destroy some very expensive auto electronics. By design, batteries appear
to play a role in circuit protection.
To his credit 'lasersaber' did carry out voltage drop measurements and
actually use the device in regular service. Could be a handy emergency
start booster if kept charged. Much more testing needed before you risk
your car or trust the device in cold weather.
But beware! Check your auto insurance policy. Exclusions often apply for
non-approved or non-original modifications unless first approved by the
insurer. Many modern cars are written-off after flood immersion due to
electronic system damage alone. This shows how costly a boost-capacitor
experiment could be if things go wrong. Amateur trials could void an auto
insurance policy in any claim for damaged electronics.
ThingsDemystified: How this device could be useful is if you're stuck with a dead battery. You
could use a solar panel to charge it.
Ryan Toomey: The capacitors should be hooked up in PARALLEL, NOT IN SERIES, because with
capacitors in series the total capacity is the reciprocal of the addition
of the reciprocals of each capacitors, giving you a much smaller total
capacitance value, smaller than the value of the smallest capacitor. In
parallel, the values of capacitors add up to give you a much larger
For example, if you have 10, 10 Farad capacitors in series, the total
capacitance value will only be 1 Farad, but if you have them in parallel,
then the total capacitance value will be 100 Farads.
John Puccetti: All the new research is with capacitors. I think this is the future.
TheSRBgamer63: Easy to start warm engine lol,how about at winter ,also how about diesel
engines :P,that ur car have some small engine i guess,bigger engines will
need more power to start.
Richy GC: Bet it wont start a diesel :)
whanson3503: So, I stumbled across this and have a few questions. I drive a big ol '09
Crown Vic named "Vicky". I also live in the frozen tundra known to some as
"Minnesota". This year I was up in Duluth and it just so happened that day
it got down to -50. Now that's not unheard of, it does happen. I was also
running my car, ham radio and AM/FM radio for 14 hours straight. Yeah 14
hours without turning the vehicle off. Wait no, I did once and that was a
mistake. Only a few minutes of being off, I couldn't start it. Which I
found odd because the battery is really only needed to start the vehicle
right? Well here is my list of questions if you could be so helpful. I am
really considering looking into your mini BoostPack setup with the attached
* Would more caps be better?
* If I had such a setup, would i have been able to do a repeat of my Duluth
trip and be able to start the car even after turning it off?
* What are the ranges of temps that these caps could tolerate?
* I also have the Goal Zero Nomad 7. I'd assume that would be enough to get
some charge back into the caps if I needed or if I let it just sit on the
* If the vehicle were to die, then what?
Sorry to ask so many questions, I am just very interested in possibly doing
this. Thanks for the help
ssuuppeerrbbooyy: Pointless to use this with a regular car.
Only hybrids and electric cars benefit from capacitors, because they can
store a lot of energy in short time, compared to lead acid battery. Then it
uses that as a buffer between the electric motor and batteries. Mainly its
used for energy recovery when you are braking. But that will be a thing of
the past with these new nanobatteries coming out (F1 uses them already, but
they are difficult to manufacture).
InvisibleYetVisible: Does putting six 2.5v caps in series not cause problems? Thats 15v? Don't
cars only really have a tolerance of up to 14v roughly?
apeek7: Question: What happens to the charging semiconductors in your car? Lets
say you don't start the car immediately - you significantly deplete the
capacitor. At the last gasp the car starts...
Now you have an almost discharged capacitor drawing massive current from
your alternator. Are you at risk of damaging the diodes in the
Protectprep: Puny capacitors are for girly men.
This bank below is a bit manlier ….
Bank of 20, 450 Volt Nippon Capacitors.
Total Volt: 9,000
Total µF: 48,000
Weight: Approx 50#
rataretrodos: I have a question... is having those capacitors useful when an emergency
situation? like for when your battery runs down or your girlfriend's
battery runs out? mabe like for those little anoying sitations you know???
Brett Hruska: Wow this will shave a ton of weight.
Kello Tao: will try this
Ben Hurd: Try a 3.4 liter v6 or a small block
bf386tr3gf38: they can switch on your car one time, but in case of missfire, you will not
be able to start car, because capacitors discharge fast...
bax442: Great test!
thefront: It'll work as long you don't need a continuous crank to get it started like
many older cars do. Though this works, it's not practical compared to the
price you can get a regular car battery for. Especially if you look at
MXStar189: chickens i hear them thats sweet road island reds?
Can Celik: hey man, can we hang out together weekends? :) these are brilliant.
Rangerman9404: I'm wondering how it would handle a high demand situation, like a car with
a high powered sub woofer amp, or a car that's usually driven at night with
all the lights on
Vanianfew Few: I can see me having capacitors all over my house,including my chicken loft.
Iraqis Tube: Well, you can use this for just few times and if it not a rechargeable
batteries it will explode while the car is working because the dynamo
charge the battery when car is working ... but if you replace it with
rechargeable batteries I think it will explode too because it is the same
volt but the the mAh are different.
Johnny Benson: Hello LaserSaber
Great video you have shared !
I am curious to know how you prevent the caps from being overcharged given
that the alternator immediate charges the caps once car is jump started
with tons of amps.
Larry198s: would be great too not using gas, gas these days are high,
staticnetwork: Perhaps you could install an electric motor in a car and use your super
capacitors and a gas generator.
Cody Grant: Your car is dirty as crap.. You need to clean that up a bit.
Robert J. Wiltshire: Reading all the negative comments is disappointing. Hearing all the people
reject this potentially awesome improvement is like listening to addicts
reject change. Yes the battery has it's pros, is it the end all be all,
probably freaking not.
Carl Williams: Come on you know we're not allowed to be energy efficient. You're going to
get us all in trouble.
Anyway, good one, that's pretty interesting, makes sense though. I look
forward to seeing your research.
wahtah955: Hey i'm thinking about a farm application. There are several things
electric tools like a drill, saw, sprayer, etc that you need power for 5-15
min pulling up to 7-9 amps. Plug it into grid or off grid system to charge
then take into the field with your tools. Maybe one you can hold around
your shoulder, if you need to walk around or climb with it. Do you think
supercapacitors/boost packs can be be effectively? thanks!
Kobe Wild: that's great an all. but caps have a limited amount of charge..
leave your headlights on for 10 min's and you won't be able to start your
rataretrodos: Hey! Great happy chicken eggs!!! Nice idea bro!!
qazmatron: Ultracapacitors have high series resistance. You can't get 100 amps to
start the car.
matthew counter: maybe you could hook up one of them chickens to start your car....
r trump: I like this, try using the crystal battery set up though the lighter to
keep it charge
Reynaldo Amador: How much? where can i order?
