Our early model you see here will use unleaded fuel rather than traditional low-lead fuel used in aviation today. The master plan is to use the scale we will create in this new market and invest it into green propulsion tech for our future aircraft. A lot is going to change in that space over the next 5 years so I'm very interested to see where things go, but I suspect hybrid-electric will be the move for the first generation of green aircraft.
Fact of the lead content, the wishes and the promises of your post have a place here.
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.
fair criticism--I should be more specific than just "green".
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.
How does further reducing lead in the fuel compare to all the other emissions' impact?
I would imagine that lead is dangerous for a long as it's being used, whereas CO2 has an annoyingly long half life that we need to actively remove in (currently) time- or energy-intensive processes, while it's reducing healthy years of life for millions of people —speaking of air pollution from combustion in general here, I don't have specific numbers for airplanes but as an airplane company you are surely better aware of this than me
