Electric Gokart

[iulian207]

dude.. its a nuclear power plant there??? look at my simple go kart

[alextrem24]

LOLLLL!!!!! . 6 car amps,1 tesla coil,12 capacictors....

[StoodOstrich9]

Man you guys dont understand electric engines at all.......

Electric engines have better take offs than gas. There is constant troque. And there has to be a limiter on the power so it just doesnt lose traction when you hit the gas duh..... And what this built is cool. I wanna see you build one... If u dont believe me look you the worlds fastest electric datsun!!!!!! :P

[200xowner]

dumb!!! geez thats like $900 in lead a copper. 2 stroke engine is what you need

[31chevylq]

have you ever seen a batteries blow up? not a good sight if you crash your cart!!!

[0MoTheG]

what are those big cylindrical things on the left on the plate behind the driver?

they look like coils. What are they for?

[pfun41]

details?

[828rb]

If you just replaced all that shit with some decent batteries and a bigger motor it would go much faster!

[unclemerck]

stupid and slow........ go to MIT and learn to build cool things

[geoff390]

Nice. I get the idea that its an expirement unlike some others. im interested in the duel power supply. I only know a little about electronic components but wouldnt the capacitors just dump a whole lot of power at once???

[dodgedart74]

what ever happend to a simple brushless dc motor, with a high watt input, and potentiometer for the throttle and a whole hell of alot of batteries?, that way all you have to do then is utilize the left over space to make the machine more efficient,: putting generators on eatch wheel, or brake pads to recharge the battery/compasitor

changing a 0% efficient machine into a 95% efficient one, idk thats just me though. very nice machine though!

[geoff390]

@dodgedart74 You wouldnt use a potentiometre, to control speed they are way inefficent due to heat from the resistance more likely to use a PWM (pulse width mondulation) controller.

[emilen2]

I was expecting 90kW and 230 kmh topspeed.. we got 1/10th of that.

Anyhow, a marvel of engineering skillz.

[MrJetjoe]

right on battery powered genrators are the future, just know that motor rateing that is the rateing on the moter is that you get out of it , try useing les moters with highter rateing, take a look a roctet bike hes machine is pedele a genrator that powers the motor and bike best of luck, good work

[bloodshot916]

I want 2 build a kart but this one sux

[conradude]

gaykart..lol

[420witchdoctor]

This thing is slow.

[aremixx06]

i fart on skates faster than that.

[EUXadamant4]

i went there for work experience last week, and that building has got loads of technology that Chris has made himself. that Go-kart's motor also has the role of a generator when its slowing down, charging the supercapacitors, so its basically a gokart that can charge itself. genius!

[monstercameron]

what a light foot!

[turpija123]

not what you'd call mindblowingly fast actually

[kalleggtk]

what is the song name??

[iulian207]

verry slow for all that technology there :))

[robertv2990]

dude that shit is slow my grandma can run faster than that i want to see wheel spin !!!!!!!!!

[bishopdante]

fairly clever, you can't beat lead acid for amp-hours. lithium won't come close. Capacitors give you plenty of amps on demand, but presumably they have a limited burst

[h4rdflip]

Is there a reason why you have a 6 stack of controllers on it, I have to say you make it look complicated when its not that bad. oo and Im glad you have a degree... btw! hehe

[esotoracing]

Nice craftmanship

[gurinski]

I hope he doesnt plan to sell that. The production cost will be through the roof and you have to have a degree fron MIT just to charge it.

[cyborgtroy]

Lead-acids are pretty easy to charge actually, just get a charger from like Batteries Plus.

Supercapacitors are even better, just hook them up to a constant-voltage source until they stop drawing current.

[DEZZIELIGHTBULB007]

You've probably had a university education yourself, which is why you don't understand when real people express themselves, which is exactly what I meant in the first place.

Get it, DUMMY?

[skowlitz]

lmfao i was thinking over engineered right before scrolled down to say it

[alex2041]

over engineered

[mellifluouschinook]

@alex2041

thats probably what they said about the wright brothers at kitty hawk

[MacintoshKiller]

where did u get the motor please inform me!

Is there anywhere i can get one cheap!

[capridrifter]

ok now lets put this into a car and scale up already!....wink wink:)

[DEZZIELIGHTBULB007]

WOW! It takes university heads to make suck an expensive pile of crap. Sure says a lot about education!!! lol

[cyborgtroy]

I can't understand what you're saying but you're totally being wrong and stupid.

[kempingpeg]

L M F A O! look at the flag!

[p51joe]

Is the capacitor an off the shelf item?

[FORDGTFANATIC]

dude you got it all wrong.....its heavy and slow simply throw a 125cc 2 stroke GAS engine on there and you will have a light weight speed monster

[ILOVESPEED25]

Yeah, you are right about the weight, but, electric can be just as fast, this guy just way too much weight on.

[chrisransom]

You missed the point, this was a technology testing kart, for possible scaling up into hybrid cars, but thanks for your comment.

[p51joe]

I see the capacitor array-are they off the shelf units? Who wound the coils? How are you regulating discharge through the powerband? IE off the shelf componentry or something self-engineered. I'm just a hobbyist trying to teach my 9 year old son alternatives to 2 stroke Internal Combustion smokers.

[0redthunder0]

Electricity doesnt produce fumes or alot of noise so its good for rural places (hence why allt he stuff i build is electric lol)

[climbamtn111]

@chrisransom YA MAN im in a percision mechanics class right now and we are also building a cart did you split your axel? our doesnt turn as well because we didnt.

[swss12]

@chrisransom hybrid cars are a waste of time, money, and effort. did i mention it's terrible for the environment? nothing beats a diesel

[StoodOstrich9]

@FORDGTFANATIC you build and electric one........

[wires99]

Nice work! Now if it were me, I'd dispense with the super caps and put more batteries on it. Speed, man!

Of course, your kart is a whole lot better looking that my "homey-made" frames...
