Wireless power has a long history, dating back to Nikola Tesla's research in the late 1800's and his grand, but unrealized vision of global wireless power.

After Tesla, the 20th century saw repeated attempts to make wireless power practical. However, Tesla's dream remained elusive, as most electronic devices continued to be powered by either wires or batteries.

Today, new advances in technology and the proliferation of novel use cases together promise to overcome the hurdles of the past and bring us closer to a world with ubiquitous wireless power.

In this talk, we explore the physics of wireless power, the engineering challenges involved, and the new possibilities enabled by recent innovations in wireless power technology.
