However "Green" only sounds good in a marketing pitches. While it might resonate with potential customers who are already sold on the idea, it can come across as vague and insubstantial to those trying to understand your response.
It sounds misleading and deceptive for the individuals who are skeptical of the environmental impact.
our first model will still be a gasoline ICE airplane, but we are building a limited number of them to get our tech out there and get a new wave of people excited about GA. out future aircraft will be able to utilize our fly-by-wire/simplified controls to fly more aerodynamically efficient airframes that will use less energy, whatever that source is. We can do this because these airframes would be too unstable for a human to fly by hand, hence the need for fly-by-wire/simplified controls in the loop.
today, we don't have a good alternative to ICE for airplanes that also meets the mission profile of the vehicle. I personally think hybrid electric is at least the next step, with hydrogen (though that has it's own challenges) coming after.
