Hi! I'm Eyvind, student in mechanical engineering and crazy manga otaku!!!

1. Electric engines have their specifications in watts or kilowatts. Only combustion engines are generally specified in horsepowers... do you want combustion engines strapped to your feet, or do you prefer electricity?

2. Just look up how much a horsepower exactly is (hint: it's close to 750 W), and calculate it yourself.

So here is some math

in the manga, the average speed of an AT is 45km/h=12.5 m/s (since is on rolerblades this a VERY GOOD speed!!!)

if you asume the AT wheel is 8 cm diameter, the angular speed is 12.5/0.04=312.5 rad/s=2984 rpm

i'm 95 kg , so my weight force is 95*9.81=931.9 N

the wheel needs to have a torque of 931.9*.04=37.3 N.m

the engine power then is 37.3*312.5=116581 W=156 hp

so............

i need an engine that fits under my shoes with:

- Power: 160 hp

- Torque: 37-40 N.m

if you guys find one let me know ok!?

NOTE: this is for an average stock AT not regalia!!!
