Airfer paramotors has a couple of new electric paramotor models as seen in the video below.  Notice how quiet they are!  The only thing you really hear is the purring of the prop.     What’s really impressive though are the flight times.  You can fly a full 60 minutes if you keep the thrust at cruise speed.
