Episode notes
Three Legs Of Wireless Power
- PowerCast builds three wireless power approaches: inductive (Qi), RF far-field, and magnetic resonance for different ranges and power needs.
- Each approach targets distinct use cases, balancing placement freedom, range, and transferred power.
Regulatory Limits Shape Air Charging
- Air beamed RF charging is technically possible but limited by regulatory power caps, so throughput and user experience vary widely.
- Eric Biel frames exposure as orders of magnitude lower than typical cell phone use, making it safe in practical deployments.
Samsung Eco Remote Cut Millions Of Batteries
- Samsung's eco remote removed alkaline batteries and used a supercapacitor topped by USB-C, solar, and PowerCast chips harvesting ambient Wi‑Fi and Bluetooth energy.
- That design eliminated millions of disposable batteries and reduced lifecycle waste for widespread TV remotes.
