I recommend you to check out this project razer page. Look at the size of his parts (i.e. batteries, motor, wires, controllers).

The batteries take up the length of the scooter, and he still needs to have an extra battery in front. With all of this, his speed is not above 20 mph, and his range is less than 4 miles. This guy is extremely knowledgeable, and those are his current limits, despite having much more room to work with than a skate. If you have an idea and can explain why it'll work better than his ideas, then go for it. Otherwise, the prospect of building a system with a tiny battery powering a tiny motor to move you 50+mph seems unrealistic.

i was thinking about, for the shoe its self use a design like the iron man boot because it gives you more room to have a motor controls and cooling capability. plus the motor shouldn't be on the inside of the wheels cause wheels wear out so u have to change the wheel every little white plus if the motor is shot then new wheels, we should think of a way to get a wheel to run on a chain or gears. if you do deside to put the motor on the out side i recemend the iron man boot idea because the motor can sit behind the ankle and have vents to provide cool. then use gears and belt to connect it to the wheels. with the motor behind the ankle you can use a much larger but light motor

ps. if any of u have msn add mine [ zerobeat24@live.com ] and we can talk about this in real time and get work done faster

i forgot to write that i found away to hold a power source we can use a battery pack the rest on your back like a backpack someone else said that you can use a liquid cell battery pack which is lighter i think it was on page three. plus with a battery the size of a back pack that can be recharged and give way more power then needed. you can have a think line that can be extended depending on your height that can be pluged in the the back of the AT's or with an adaptor can be pluged into the wall

well actually possibly the battery could strap on your legs, wouldnt have cords tangle up in it. im thinking the engine should probably be either magnet motor or a engine which like could spin a gear around it self make inside wheel move

also about the faraday thing, cars today use it. when people brake down hills i generates power. my mom has a 06 car since it came out and shes never once had to change/power the battery. this faraday thing might actually work. they also have small generators like that in some laptops, and it takes little cranking to generate quite a bit of power. they use those in africa.

@wingroad: That is a good idea. I actually suggested it a long time ago (i.e. over half a year ago at least). Your recommendation about the motor is called a hub motor, with gears. Also, using Faraday's law would only be effective if you are going downhill, braking, or powering the skate yourself by normal skating.

@jay24: Yes, it makes more sense to have an external motor and battery. However, I think most people want to look *cool* and Air Gear-like as opposed to motosk8-like.

the farady thing i believe would work because they use their normal skating abilities in air gear most of the time to get moving, its only after they are moving that they can rely on the motors.

OK so i just read about 40 pages and wow
so i have ideas but can not express them for any one to comprehend cause i forgett them i shall return thou and hope that i write things down but im currently rooting for magnet
at least we could start there for the time as a prototype
even if it incresses ones speed a little it would be progress yeah?

Well i think i know one way to make the baterry work but it wouldnt really be allowed,if i remember correctly from a exposa I read in a major magazine,they had an Atomic Nuclear powered watch that would have enough power to supply it but they werent allowing them for civilian use,so get a DoD contract and there ya go Air Treks rofl and guys get me the schematics and all and i have more than enough funds to make a prototype

Edit add on.

They actually have a micro engine that can fit in your hand and can dish out about 40 horsepower

ok so for me the battery in the backpack is the best plan for now because if its on your legs you might get burned or just plan less mobility
however the backpack gives support and this would leave more room on the ats themselfs
the question would be what sized battery do we need and will this be a compramising factor while riding the ats?

Well, the size of the battery depends on how far you'd want to go before needing to recharge.

@Syrius: There's small motors that can propel you, but the main problem is that they don't go in the wheel. If you want to compromise and use an external motor, then there's many more possibilities.

what if we had a motor that wraped around the top?
and had some sort of cover so it was hidden

oh and earlier someone was talking of overheating (motor in wheel)
but this might be fixed simply if i remember correctly the wind regalia had a (umm cant remember the word)(looks like a Propeller for a 747) but ok
if this is on the wheel then it should cool when its being used and save energy at the same time

An AT is possible to make, but it truly is the power source, would we use batteries? or solar power? would we need to re-charge later for the batteries?
another problem is making a motor strong enough to propel a person high in the air with blinding speed.
Although there are some minor problems, I think it is possible to make an AT, once you make the motor, it's all downhill. you can use the format from Roller Blades, design special rubber wheels, custom made to fit the AT's needs, a motor, and some suspension.

You guys, what im saying about the faraday thing is, every time the wheel moves it generates power. the battery powers the engine which moves the wheel. each revolution of the wheel powers the battery. and so on. its basically an infinite loop of power

^^ It won't work, and you must have a poor understanding of physics to not see why it won't work. Your "infinite loop" is no different than the following argument...

1) I tie a string to a ball and my arm, then throw the ball really fast upwards.
2) The ball will move so fast that it drags me upwards towards it.
3) Once I reach the ball, I throw it up really fast again.
4) Repeat the process, making an infinite loop in which I fly to the moon.

If you ever wonder why I have doubts on whether you can build this contraption, take a look at this plan. Any "infinte loop" that is a closed system boils down to this. Feel free to try this genius plan, and tell me how it works out.

@SamuraiKye: Not enough solar power can be collected on the size of a skate to power it, even if you could catch 100% of the solar energy. I imagine in the future, an application like this would use super capacitors, where you simply plug it in at home for a nearly instant recharge. Whenever you run out, you'd just find another socket to plug it in. Motors are possible, but won't make you as fast as a car anytime soon.

Tell me how much power would you need in a motor to make an average person move and able to go 25-50 mph?

________________

^^Well, 25-50mph is a big range, and it would depend on how much the person weighs, how fast you need to accelerate, and especially how much you gear your motors, etc. It could take anywhere from 400-1000+ watts to hit that 25mph target, and much more if you aim for higher.

A quick look shows that most scooters will get you around 20mph with 500 watts.
