As we slowing grind our way into the second decade of the 21st century, aviation is starting to see the need to move towards more enviromental friendly skies. On Nov 20, the first Pipistrel EV aircraft made its way to Canada, and what a lovey bird it is:
The BIG negative to me would be VFR Only, but could be a fun “Play” aircraft, if reasonably priced.
Whatever a reasonable price is – after spending $1000’s on a computer system, monitor and peripherals, the cost of a plane is really insignificant !!
How quickly does an Electric GA trainer plane take to charge. Time sitting on the ground , charging back up the battery, during potential flight training time, is money lost.
Are the Batteries like Tesla Quick Charge batteries ?
Like it or not, this is the way we are going. It wasn’t that long ago that electric cars were seen as a novelty that were inferior in most every way to a gas powered vehicle. Now they are commonplace.
The biggest problem I see with the adoption of electric flight will be the rapid obsolescence of the early aircraft. A state of the art electric airplane of today will probably be totally outdated in just a few years. I guess that was the same situation back in the early days of flight when progress was rapid. The difference was that airplanes were relatively cheap to build back then.
If only we could get the power to weight ratio and torque of an electric motor with the range of a gas burning piston. The Long-EZ is already amazingly efficient with a 1500-2000 mi range on 50 gallons of avgas, so it probably makes a decent testbed for early stage electric conversions.
The lithium-air battery, developed at the Japanese National Institute for Materials Science (NIMS), had an energy density of over 500Wh/kg. By comparison, lithium-ion batteries found in Tesla vehicles have an energy density of 260Wh/kg.
Energy density has been the biggest obstacle towards the advancement of electric planes, with 500Wh/kg viewed as an important benchmark for achieving both long-haul and high-capacity flights.
WOW !! Lithium-air batteries have the potential to hold up to five times more energy than lithium-ion batteries of the same size (3,460 Wh/kg),
