Yeah right. Maybe revolutionize what I do when I'm bored out of my mind though.
So, we all know of the Segway, its mechanics are simple. Little mini gyroscopes send messages to motors. Its all processed so that, a lean forward or backwards will throw the gyroscopes off, sending a message of force,
and processing measures to correct the force, thereby moving the scooter, seemlessly.
Okay. So, imagine a big disc with an engine in the center. There are, say, 200 exhaust outlets for said engine covering the circumference of the dics and pointed towards the ground. If you jump on this thing and turn it on, it'll tip you in seconds. However, with the same gyroscopic assembly as the segway, control the arrangement of exaust using a relay intersection of sorts between the engine and its 200 exhaust options. The gyroscopes send messages to a processor which then chooses which arrangement of exhaust tubes to engage in order to correct any unbalancing. The balancing act happens on the order of 60 times a second, with tiny microbursts spitting out of any number of the rim exhaust pipes at any given moment.
This mechanism only balances the hoverboard in the air. Locamotion is controlled by a different system located on board with exhaust parallel to the ground.
What, like this?
