The GyroTwister-Xbeam with lights!

An experienced user can get the GyroTwister up to 14,000 rotations per minute. The GyroTwister generates rotation power of up to 18 kg. What could be easier than harnessing this enormous power to produce energy? We've done exactly this with the new GyroTwister-Xbeam. The Xbeam has a built-in electricity generator that produces enough energy to light up the device in an amazing way. Intensive light is produced in all directions. So don't used the blue Xbeam at night in your car or someone might think it's the police...

This is how the Xbeam works
Since the GyroTwister Xbeam creates the energy it needs itself, you won't need any batteries. After years of use, your Xbeam will still light up as it did on the very first day. Xbeam works in the same basic way as the GyroTwister Classic. What's different is that the Xbeam has two high-performance copper spools mounted on its rotor, the heart of the Gyrotwister. The spools are guided past permanent magnets that are attached to the Xbeam's outside covering. This creates an induction current. This same principle is used for a bicycle's dynamo lightlamp, where a magnet turning in a spool is powered by the front or rear bicycle wheel as you pedal. The ends of the spool hang outside the dynamo covering, so that the electricity can be used to generate the bicycle's light. This principle had to be modified when we created the new Xbeam. The spools had to be attached to the outside covering, and LED lights were mounted to the covering, to create "constant light". The Xbeam is built completely in reverse to a bicycle light. The permanent magnet is attached firmly to the covering and the spools from which the electricity is derived are located on the rotor. The 4 power LEDs are also attached to the rotor. The result is 4 extremely bright LEDs which, together with the rotor, achieve up to 14,000 RPMs around their own axis. (The Xbeam itself can achieve up to 15,000 RPM, although average human coordination capabilities are far below this level). An unbelievable effect.

How does the GyroTwister work?
Imagine you´re holding a glass of ice cubes in your palm and you shake the ice around the inside wall of your glass. The GyroTwister works without batteries! You power it up using pure muscle power. Inside the device, you´ll find a 200 gram rotor - the heart of the GyroTwister. Once it´s set into motion, a rotation impulse starts up around the axis. Bike riders are familiar with this kind of impulse. If you get on a bike that´s not moving, you´ll fall over. But the faster you ride, the more stabile the bike becomes. To steer, more power has to be used as speeds increase. The rotor within the GyroTwister is able to build up stability In exactly the same way – through the moment of inertia (the gyrating mass is about 2 cm (1/2 inch) from the axis) and the rotation speed. The user can now try to tilt the rotor, while simultaneously turning the rotation axis, to create a moment when the rotor beings turning. The gyroscope reacts to this movement with an opposite motion in an attempt to straighten upright again. This power force is known as "precession". The opposite reaction movement is stronger than you might first think. The principle of precession is probably familiar to those who´ve tried to roll a bicycle or car tire down the street. At first the tire rolls straight and upright, then it turns to the left or right and then straight again, only to beginning turning all over again. In contrast to a tire being rolled along the street, the rotor inside the GyroTwister is guided in a circular motion. The GyroTwister can´t stand completely upright - instead, the precession is channeled by the guiding movement. The only "way out" for the rotor is to "roll away" from the guiding control, which increases the rotor speed. In the meantime, the user has tilted the body another quarter turn and the rotor continues its precession. This process continues on. The energy used by the user is converted into increased rotations for the rotor. This way it´s possible to speed up the rotor to 10,000 rotations per minute. The rotor is surrounded by gyrating movements which are 75 times higher than the actual weight of the rotor - that is, up to 15 kg or 33 pounds more! When the user no longer moves the rotor, the energy stored in the rotations is used by the friction.
