Flying Cars! Ian Villa, Founder of Whisper Aero is building silent engines for EVTOLs - electric vertical takeoff and landing vehicles.

Joe talks to Ian about how EVTOLs work - from batteries to electric engines, why electric aircraft are cheaper than jet fuel-powered helicopters (hint: It's the jet fuel), and what cities will look like if these vehicles start taking off, which could be as soon as 2024.
