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.
