Abstract:
1. A water transport system, comprising: a wafer transport enclosure having a first interior side wall and a second interior side wall opposed to said first interior side wall, said wafer transport enclosure connected to a first chamber through a first transition chamber and a second chamber through a second transition chamber, wherein the first transition chamber and the second transition chamber are constructed to provide environmental isolation to the first chamber and the second chamber respectively; a first lift magnet rail located along said first interior side wall; a second lift magnet rail located along said second interior side wall; a transport shuttle having at least one propulsion magnet and a plurality of support magnets adapted to magnetically couple with said first lift magnet rail and said second lift magnet rail to keep the transport shuttle suspended in the wafer transport enclosure through a magnetic repulsion force among the plurality of support magnets, the first lift magnet rail, and the second lift magnet rail; and a propulsion coil located along at least a portion of said first interior side wall of said wafer transport enclosure and adapted to magnetically couple with said one or more propulsion magnets in the transport shuttle, said propulsion coil for driving said transport shuttle between said first chamber and said second chamber along said first lift magnet rail and said second lift magnet rail.
