Electric Go Kart with Graphene supercapacitor. Random Questions on electronics, control, and possible problems.

I have a project in mind that i am trying to start on and it all has to be done as cheap as possible (ACAP). The project idea is that after my graphene in finished and I make the capacitors I will construct the battery and group the many cells in series and parallels until I have either 36 or 48 volts and a lot of amp-hours or at least enough to drive the kart with unrestricted speed for AT LEAST 10-15 minutes.

The big question I have is whether i can treat these, essentially fast charging batteries, as batteries or if I must use different methods to control power and connect to the motor. 

Then I also don't know how exactly i am going to control the motor or even what type of motor to use and where to obtain it. I was thinking i could use some industrial PMDC motor and I would like to control it using a PWM and use a plate that a contact touches that would slide up and down the plate to make the contact closer and farther away from the end on which a cable would be attached so it varies the amount of resistance to make a potentiometer. The closed throttle would just be a button that the pedal pushes to disconnect the power to the potentiometer at another point in the wiring. If that actually works then how would I make or where would I buy something that could actually use that and be able to handle thousands of watts (like 10,000W @36-48volts minimum). 

My other throttle idea was that i could just have the pedal activate multiple solenoids so that there is like 5 stages of power activated by the solenoids. I have heard that problems with this is that when the first battery runs out you have to charge it otherwise it will be destroyed, though i am not sure if this will affect the graphene supercapacitors. If anyone know anything about graphene in applications please let me know because that would be way easier.

The last thing is that since the graphene will be made on disks by laser scribing them could i just make the cells the shape of CD disks and then put the in one of those disk holders and then wire those to each other in series until i have the desired voltage and then in parallels until I run out???

If anyone has made graphene cells and used them please tell me where u obtained the Graphene oxide and how you made the graphene and cells and etc.

Walk before you run!

Finish the capacitors and check that they can store sufficient charge to something useful before setting yourself grand targets.

(PS you have weird key words - you do know that the correct term for "graphene oxide" is "carbon dioxide", don't you?)

put some numbers together, but super caps really can't hack it yet.

1. unknown/untried technology is never cheap.

2. Do the maths and work out the power available to you against the power used to get some idea of range and speed.

3. There doesn't seem to be a question here - Good luck
