Any safety concerns?
Safety is paramount in the design of the GTX. Unlike a large metal flywheel weighing hundreds of pounds, the 25 pound Pentadyne flywheel will not fragment. In descructive tests, the carbon-fiber flywheel simply unravels into fibers and dust adhering to the inner housing like cotton candy. More than 30 different such tests were performed at Pentadyne to ensure that no part of the spinning mass could ever escape the housing. The rotating mass is contained within two housings: a 2-inch-thick steel inner housing that surrounds the rotating group, and a separate steel outer housing. The inner housing is over-engineered to handle the pressure load and contain all the flywheel elements in the unlikely event of a rotating group failure. The cavity between the two housings is filled with a viscous non-toxic fluid that acts as a coolant during normal operation and as a hydrodynamic buffer if a failure such as this were ever able to occur. The inner housing is attached to the outer housing via br
