Segways

ok so far, going smoothly up till now dont speak too soon

No a segway is like a bike. You don't need a license, all you need to do is buy and ride, and its recommend that a helmet is worn since many can reach speed of 20 mph.
No

The fundamental idea behind the working of a gyroscope is that of conservation of angular momentum. But to understand this idea more fully, it may help to explain a few things, so let's dive in by talking about a wheel and axle and how its mounted.

If a wheel or disc spins about a center on a axle, that spinning wheel carries with it some kinetic energy. The wheel has mass, it took energy to set it spinning, and it is now spinning, hence the energy of its spin (momentum). If we then mount the axle in a ring, we can hold the ring and the wheel will spin on the axle. Now we'll mount the ring with the spinning wheel in it.

When we look at the ring with the spinning wheel in it, we can find two points on our ring that are in the plane of rotation of the wheel. We then put two small "stubs" out from there and mount our first ring in another ring. The mount will allow us to hold the outer ring and allow the inner ring to move independently. Lastly, we take a third ring and mount the whole thing inside that one. But we need to be sure to pick two points on the plane of rotation of the wheel, but 90 degrees from the points where the innermost ring mounts to the second ring. We have set up gimbals so the outer most ring can be mounted to an object and the inner rings will allow the axle of the spinning wheel to always point in the same direction.

The use of very low friction components in our mountings and the application of electromagnetic pulses to keep the gyroscope spinning will insure things keep working. And by using sensors to keep track of the orientation of the rings, we can use this device to keep track of movement. The Wikipedia link below will allow an investigator to jump to the gyroscope article posted there. It is extremely helpful because the moving diagrams there will allow inspection of a gyroscope in action. With the outermost frame mounted and the gimbals operating properly, the axle, which is the axis of rotation of the wheel, will always point in the same direction regardless of the orientation of whatever the frame is mounted to.

No. Motorized electric bikes and scooters are not at this time legal on any public sidewalk, street or highway in New York State.

Note that this class of vehicles includes the Segway, Razor electric bikes, Go-Peds, etc.

Hope this helps.

There are actually quite a few positive aspects of multimedia. Some media sources promote healthy living and proper exercising for example.
