Harbour Air, based in Vancouver, BC, Canada is making moves towards converting their entire fleet of about 40 seaplanes to electric power. They have teamed up with MagniX of WA to test fly an electric DeHavalind Beaver later this year, with the goal of ultimately being the world's first airline to operate an exclusively electric fleet.
All electric airline...cool!
