The next one uses an old invention by a different caveman from the past...in a new school way by Nuimshaan.
It used to be called the magic wand or something....anyways...it was a magnetized gyro wheel on two steel rods, whereas the gyro wheel would roll away from you and back towards you on the two steel rods.
In the drawing you see, the gyro wheel is rolling between two thin plates of steel. The illustration is drawn in the "side view" perspective. Because it is necessary to show the downhill slopes in this device.
It shows how the gyro wheel is able to roll downhill to the left, even though it is spinning clockwise.
It also shows how the gyro wheel is then able to roll downhill to the right, and still be spinning clockwise.
There are two forces at play here. One is the speed of this gyro wheel rolling in this device. The other is the spin speed of the gyro wheel while it moves around.
The spin speed is called it's flywheel rpm.
How fast it moves down the slopes is called it's travel speed.
It's important to note, that after the gyro wheel rolls downhill to the left, and downhill to the right, it has not only gained travel speed, but it has gained flywheel rpm also.
Keep in mind it is magnetized as it approaches the uphill turn. Keep in mind it is has a high flywheel rpm, and travel speed momentum going up the uphill turn. It does not peel out half way through the uphill turn, all of the flywheel energy is combined with the travel speed energy to make it go through the uphill turn, and then start the trip through both downhill sections again...except faster. This device should force the gyro wheel to gain flywheel rpm and travel speed until it cannot move around any faster.
There are several tweaks for this one. You can stretch the downhill sections out...make them shorter, blah blah. You can change the circumfrence of the gyro wheel axle and thusly change the flywheel rpm..blah blah.
Here's the cool part: You can get one gyro wheel going....then add another one and get it going at the same time in this device.
It is simply two identical thin steel plates with that tear drop shape cut out of the center of them, and then those steel plates fixed inches apart, and the gyro wheel's magnetized axle can touch both of them at the same time, rolling downhill to the left spinning clockwise, and roll downhill to the right spinning clockwise.http://a4.ec-images.myspacecdn.com/imag ... b028/l.jpg
