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.
Have fun!
What, like this?

How BIG is the engine on this vehicle? I would have thought you would need a fair bit of power to run this. Let alone lift you off the ground, then again this is the HB<grumble, grumble> |
|

Agreed. Reaction-jet control systems are well baked. Figure out how to package a lift system into a device small enough to be called a hoverdisc, and I'll give you a bun. |

How about a twinning scheme for
hoverdiscs?
First, you have
to find a buddy who lives on the
opposite side of the world. Then, you
and he (or he and you, or you and she)
each buy an economy hoverdisc. These
budget sports items lack any lift-
generating device, but have two little
bracket-fittings on opposite edges
(helpfully marked 'L' and
'R').
Each of you now buys one
very large hoop. The hoops are semi-
circular, with a diameter (end-to-end
distance) of 12,756.301 kilometers, and
are made of an adequately stiff
material. One end of each hoop fits
into one of the sockets on each side of
your respective economy hoverboards.
Since the diameter of the earth is only
12,756.300km (says Google), you will
each float, magically, 50 centimetres
above the
surface of the ground in your respective
countries. |

Better to use an enemy rather than a buddy as this person will now remain the human being furthest from you at all times. |

[DrC] - Fantastic link. I want it. |

//Better to use an enemy rather than a
buddy// Ah, but if you did this and
your hated counterpart suddenly
stepped off his Economy Hoverboard,
you would suddenly be let down. You
need a friend on the other board, and
preferably one of the same weight. |

It's as much a hovercraft as a pancake is a waffle. |

The post describes a free flying craft not one bound to the Earth by a skirt. |

Thanks, [Bris], no skirts for sure. |

"It's as much a hovercraft as a pancake is a
waffle."
That should be a hb tagline. |

We can only make it work. |

Just use the [marked-for-implementation] tag, and it will be automatically added to the halfbakery software. |

You could make some crazy smoke patterns depending on how you shifted your balance. That's a neat illustration, [Bris]. |
