I stumbled apon this thread while conducting research on wats been done so far.

 

if someone can post what sort of baseline wattage is required to move a person on 8 (or 4) comparatively small wheels then I can start prototyping based on a concept I've been working on (might post up my Pro Desktop pics some time soon but still a bit paranoid about posting unpatented concepts on the net.)

 

EDIT Never mind the last part!

 

p.s about the issue of each foot differing in speed you can sync them by a radio+speedcontroller if you get what I mean.

the radio speed controller, with some more of the ideas previously posted, you might be able to. it would be entirely circuit, and small enough to fit

one thought is that you might be able to use two different engines- if small enough- to power it proficiently. the problem is, after you have the motor taking up the space, the air cushion and suspension system are toast. the suspension might take half of the rollerblade itself.

Merged post follows:

Then I would go with the electric motors you find in the battery-powered drills or electric screw drivers. You will need a gearbox though. The batteries on those tools will give you at least a few minutes of fun before they are empty...

if you connect the drill batteries to a, lets say a small car battery, u would have a large amount of time. leaving room for the safety issues of the air cushion an suspension. Also, having that load cell would probably be a better indication of how much power will be used
