my bad...forgot to calculate that there were 2 lithium ion batteries and 2 gear head motors...

Total Estimate Price=$145.80

[chris-chan]

not bad, but did you think of scooter wheels instead of roller blade wheels? theyre bigger, so theyre more realistic. and i know energizer sels AA Li ion batterys for four for $9 (i think, cant really remember to well). and what was the brand of the batteries you were gonna use? id like to check them out and get a look at their size to see if theyd work in my design.

i can get a pic...i'll pm it to u when i do

thanks man.

oh, and heres my list so far. (no prices)
4-scooter wheels
aluminum square tubing
fiberglass cloth
resin
hardener
12-screws
1-motor
4-bolts
1-chain/pulley
4-6-Li ion batteries
1-rc car speed control
1-pressure sensitive switch
2-shoes (old etnies)
2-gears

thats about it so far. theyll probably will be more ill remember along the way or think of. but thats about it. oh, and im making one trek pwered and the ohter one just a trailing one like in the series.

[Q-Tron]

cool...but make sure the one that's powered doesn't weigh too much more than the one that's not...try to make them the same by counterbalancing the non-powered AT...

[chris-chan]

thats what i was thinking. im hoping that in the end these things weigh between 2-3 lbs and no more.

it's not about infinite energy, nor is it about 100% efficiency. You gain no benefit from putting a generator on the skates in this manner.

A generator takes work and turns it into electricity. This energy required to create this work must come from somewhere, and the only energy source is the battery. So now, instead of powering just the propulsion, the battery is also pushing the generator. Even with 100% efficiency in this energy conversion (which is effectively impossible) all you are doing is putting the same energy you took out of the battery immediately back into it, gaining ZERO energy savings. Why not just yank out the generator, and all energy can be sent to the wheels where you want it.

I'll bust out formal equasions if you guys want me to. Before taking a half-dozen semesters of phyiscs, I came up with these sort of ideas all the time. There is zero free energy. infinte or infintessimal.

[chris-chan]

what he was talking about was taking kinetic energy from the wheels moving and turining it into electrical energy to repower the battreies a little bit. in theroy, it makes sense, is it possible, like you said, probably not.

[Q-Tron]

yea..i'm not sure...in other news..i found that making that section of the frame that contains the electronic parts, like the motor and stuff, is going to be difficult because it has to be comfortable and withstand impact so the parts aren't destroyed...

[chris-chan]

thats why i was saying aluminum reinforced with fiberglass or carbon fiber and to make sure you triangulate it. (the riangle shape helps distribute force throughout each side) it shouldnt be to hard. what i was thinking was making the part the holds the electronics out of aluminum and triangulating it like crazy, then attaching it to a base the adding stryofoam to shape it, then covering it in fiberglass to reinforce it. if all works out it will become one solid piece where the wheels can be detatched for changing.

[Q-Tron]

sounds sweet...i'm not sure if i have the capabilities to do all of that...if i sent you the styrofoam model i'm making, could you make reinforce it and all of that stuff? i'll pay u the costs...?

[chris-chan]

ill have to see how mine comes out and if im really dedicated to doing it again. dont get me wrong, id love to help you, but if its too tedious and all, i wont want to do it again. wait till i finish mine and if youre not done, il lsee what i could do.

[Q-Tron]

okay...i have an idea to do mine, but it's not as good as yours..if mine doesn't turn out too well, then i'll have you take a look at it..if you're willing...gosh, i can't wait for all of this to happen..i can't wait for it to be a big sport with little specialty AT shops, knowing that this is where it all started...lol..this is sooo cool!
