On December 11th Vancouver based Harbour Air will test fly the world's first all-electric plane for an all electric commercial airline. The converted 6 passenger de Havilland DHC-2 beaver will take off from from the middle arm of the Fraser River near Richmond British Columbia. In February of this year Harbour Air announced that it would be converting all of its 40 propeller-driven seaplanes to electric to make it the first emissions free all-electric airline.
This is revolutionary because air travel is notoriously harmful to the environment.
