The ability of flywheels to deliver very high power for a short time has been used in inertial friction welding and in some machines such as inertial starters. The rotor specific energy was 5 W h/kg, and the system specific power was 100 W/kg. A typical energy storage flywheel has a shaft with a rotor attached and a motor generator that can both drive the shaft and extract energy from it. The world's largest magnetic confinement fusion experiment. Low-speed flywheels, with typical operating speeds up to 6000 rev/min, are constructed with steel rotors and conventional bearings. Such units could also provide uninterruptible power for factories. JET was de eerste tokamak ter wereld waarin met de echte fusiebrandstof, deuterium en tritium, gewerkt werd. The Joint European Torus in Oxfordshire will create temperatures ten times hotter than our Sun to induce nuclear fusion, and it could spark an energy revolution Between shots the wheels are accelerated from half speed to full speed over a period of 540 s (9 min) using 8.8 MW motors. Storing energy with flywheels has occurred for many years. The flywheel is mainly used for uninterrupted power supply (UPS), emergency power system (EPS), load shifting, and frequency control. (I'm a current PhD student on JET) --CnlPepper 00:04, 13 Jan 2005 (UTC) (puke) we have differnt disabiguation pages at JET and jet (disambiguation) my suggestion would be to redirect JET to here and add a pointer to jet (disambiguation). The engine runs an alternator that continuously charges the flywheel. JET has been in operation since 1983.

Still it's full name is "Joint European Torus" and its how we refer to it in our own PR material. As the composite forerunner pointed out over 20 years ago, composite materials are one of the most suitable materials for flywheels rotating with high speed (Post and Post, 1973). Flywheels store kinetic energy in a rotating mass, with the amount of stored energy (capacity) being dependent on the rotor inertia as determined by the mass and form, and rotational speed. Shintarou Kitade, in Comprehensive Composite Materials, 2000. When the electric power is required, this kinetic energy is converted to electricity by the generator coupled with the flywheel. A single plasma pulse at JET requires peak power of 1000 MW and occasionally more. Joint European Torus (JET) The JET is the largest man made nuclear fusion reactor. Here, the flywheel is used for times when high power is required, thereby allowing the internal combustion engine to run at a fixed rate where efficiency can be optimized and exhaust pollutants can be minimized. This paper addresses the history of JET, the Tokamak that reached the highest performances and the experiment that so far came closest to the eventual goal of a fusion reactor. The Joint European Torus (JET) Rebut, Paul-Henri; Abstract. JET was designed to study fusion in conditions approaching those needed for a power plant. Here's the most common abbreviation. Low mass flywheels are attractive in mobile applications, and other components such as bearings can be smaller and lighter.
