Pro Hockey Players Experiment with Heated Skates
According to Reuters, a few NHL players are trying out heated skates that are designed to cut down on friction on the ice.A resistor in the blades is powered by a rechargeable battery and regulated by a microprocessor located in the heel of the skate. The resistor heats the blade to 5 degrees Celsius (41 degrees Fahrenheit), or just above freezing point, and thickens the film of water between ice and blade that acts as a lubricant and makes skating possible.
