In essence, you blow an air stream between two "hot wires" and the differential cooling is a measure of the deflection of the air jet and the rate of rotation of the platform. -- Dale Chayes Lamont-Doherty Geological Observatory of Columbia University Route 9W, Palisades, N.Y. 10964 dale@lamont.ldgo.columbia.edu voice: (914) 359-2900 extension 434 fax: (914) 359-6817
