Resort Power Use • Ski resorts can pull up to 7.2 megawatts of power under heavy load • At 500 watts per station, 20 stations only represent 10 kW (~0.15% of total usage)

Looking Ahead • Scale up our test coil to a more realistic size. • Find a way to integrate temperature sensing and feedback for controls. • Test safety of inserts and interactions with metal implants and jewelry.

Thank You
