The answer is a clear “Kind of…”.
If you want a more detailed reply, maybe you should watch this video from AVweb VODCAST with Paul Bertorelli interviewing Dr. Pat Anderson of Embry-Riddle Aeronautical University:
Years ago, I visited Dr. Anderson at ERAU and saw him work with his students on improving battery technology and controllers and on ways to make them safe for use on board of airplanes.
At the time we had all high hopes that batteries would develop fast into lighter and more dense energy storage solutions.
When I talked with him more recently, I took one message home from the conversation: “In the last ten years battery storage capacity has improved 3% per year on the average.”
That does not sound too encouraging from the mouth of someone who really has spent much of his time in the last ten years to acquire knowledge and expertise about electric flight like almost no one else.
And it is clear, as of today, we cannot design and produce an aircraft with electric propulsion from batteries that can compete with comparable light aircraft. The problem are the batteries. They are not there yet. That may change. But as long as we have no concrete information about new developments, we cannot count on that.
But there is one thing we can do today: We can create a pure electric airplane, based on MS-1, that would be ideal to serve in a flight school environment. Many flight training missions take an hour flight time. Beyond that we need 30 minutes reserve. That’s an FAA standard which will not be up for discussion.
But an hour and thirty minutes is doable with batteries.
And in a flight school environment, airplanes return to the home base after such a mission. There they can be recharged. Like this:
We will develop the airplane and the charging infrastructure for flight schools and FBOs.
The next step will be an airplane with electric motor, batteries and range extender. What we call Hybrid on our roads. This one will have a range similar to today’s piston engine aircraft but will be much less polluting the planet.
This is not yet the ideal solution. But a big step forward and a thousand times better than doing nothing.
