17000 RPM turbine digital thermometer Tesla vortex style turbine

This is a Vortex tube that is designed for cold generation applications from compressed air. I am using the vortex to spin a thermometer at 17000 rpm with only vortex air surface contact and no turbine blades. This appears to be a more efficient method of spinning flywheels. This discovery lead me to the new EASY DIY STEAM TURBINE One Inch Diameter = Circumference of 3.14 inches @ 17000 rpm x 3.14 = 53380 inches per minute divided x 12 = 4448 feet per minute divided x 5280 = .842 mile per minute .842 x 60 = 50.5 miles per hour top speed. Not bad for a non contact blade free turbine. www.youtube.com
