THE SKI-TRAC DOME houses a huge 175-metre (570 ft.) diameter rotating snowfield. Its outer 50 metres (160 ft.) comprises a metal structural deck that flexes over a pre-set profile as it rotates, as illustrated below.

 

 

Using new "Mag-lev" technology, the snow deck, with its 200 mm (8 in) snow cover will "float" on an electro-magnetic field without the need for wheels, thus ensuring frictionless, vibrationless, silent, and maintenance-free rotation. Drive power will be supplied by linear motor.
