Not sure how much innovation this is, considering it trades extended flight time for the inability to replace the battery pack. You get to fly longer, but once you're done, you're done until you can plug it in and give it the 90 minutes it needs to recharge. For most applications, field-swappable batteries are a must.
The real breakthroughs will come from new battery chemistry and fuel cells.
