 Hello, I'm Peter Harrop, Chairman of ID TechX and I'm very excited because we're going to interview George Bayh, who is legendary in my opinion in the aviation field. I've listened to him at aviation conferences many times and he has a remarkable story he's just told us in his presentation of a single propeller aircraft having multiple benefits. Can you fill us in a bit, George? Oh, I'm happy to be. Thank you so much. I'm honored to be here. The SunFlyer is an electric propulsion airplane and of course we're using the very latest batteries and motor but the key thing about the SunFlyer is that it's reducing the operating cost. It transforms an industry, perhaps even disrupts an industry because that operating cost is so low, about $3 per flight hour compared to a Cessna 172, which is maybe $45, $50 per flight hour. But the program has advanced nicely. We're doing some ground testing. Just recently we finished that. We're getting ready to fly the airplane so it's a very exciting time for the program. That's wonderful. You were telling us that pilot training is such a huge thing. I remember in the past you used to say that you could perhaps save $100,000 of aviation fuel in training a pilot and you're moving that forward today with your story. So most pilots trained in the US, I was interested but that's not necessarily going to be true in the future. Yeah, we don't see that, it's certainly the case today, but we don't see that as much for the future as electric aviation doesn't require the logistics, the support with fuel, the fuel farms and the import of this expensive leaded aviation gasoline. So having the electric availability allows electric aviation and of course it can be much more widespread because it doesn't have that limitation. And in Electric Vehicles Land, water and air, there's has been traditionally for the pure electric vehicles that you're talking about, quite a worry about the range, call it duration in the aviation field. And we do worry about hearing these sort of call it manned drones, these things with lifters that might need a megawatt to take off. They seem to have a duration of only 20 minutes or half an hour. I can't imagine that city authorities are going to even allow them to fly over but you're going right to the other end. You're moving the envelope further, as far as I can see, than anyone else. Am I right to understand three hours duration? Indeed, plus the reserve on top of that. And the key there is that of course as an airplane and as a certified airplane I have much more battery capacity. I've got a full three hours of battery capacity and of course as an airplane my lift equation, the physics of flying, is much, much more efficient than the direct high intensity thrust required for a VTOL. Indeed, absolutely. So I have a much easier equation to solve. Yeah, absolutely. Absolutely. And I suppose there can be a roadmap further forward as well, because I remember you talking about the types of battery you're using, it's a very similar story to the story in cars, there are only a very few small number of manufacturers and you are using them the same as the car people because you have to be very careful about the other two or three hundred who are in back streets making dirty, literally in not clean conditions, unsafe batteries sometimes. But in your moving that forward, you've got the prospect of course of greater energy density from these fabulous companies that are leading the battery field, but you told us a little about propellers going backwards and solar wings, so there is a roadmap to go even further from energy harvesting, shall we call it, regeneration. Electric aviation allows very efficient use of energy and the ability to recapture it. When we're taxiing the airplane, the sun flyer and we come to a stop at a taxiway, the motor stops. There's no idle, if you will. When we fly, we climb, accelerate and cruise, of course, consuming energy, but what's interesting is the motor becomes a generator when we decelerate or descent. So it's a wonderful recapture of the energy that has been created as we accelerate and climb back going downhill, just like a hybrid car or electric car. Well, we've heard with construction machines and the like, they have an incentive way beyond cost of being able to work over longer hours. Like a construction machine in the middle of a city is typically allowed to work only for about four hours because it's so disruptive and they dream of having them day and night. Now, there's some sort of equivalent there with you, isn't there? If there's lots of residential buildings around an airstrip, you might be allowed longer hours. Indeed. In fact, in Europe, particularly, there are noise restrictions for training operations. Conventional airplanes are quite noisy. The internal combustion engines are quite noisy. Electric, almost silent. We did some testing with the National Park Service in the US and at 500 feet overhead, you could not perceive the airplane and it was wonderful. No noise, no pollution. What a great solution. Yes, that's wonderful. And do you have any interest in the charging of your aircraft on the ground with green technology? I mean, would you supply solar panels or a little solar hanger? Are you in that? The possibility of electric aviation, I think, also creates support industry. We're not ourselves in the building of the hangars and solar panels for hangars and things. But what a wonderful connection of different industries coming together. An airport could be entirely off-grid. Yes, yes. A future airport entirely off-grid. What an amazing possibility. Yeah, that's amazing. Yes, we've written one or two reports recently about people moving off-grid, both buildings and cities and the rest. And it seems to be a trend now to get off-grid, to get better security of supply, lower costs, more control, and also transportability. You can move your equipment, if you wish, to some better place. But could we perhaps round off? I'll be challenging. 10 years from now, we're understanding you're actually facing into a market, even for this one model of aircraft that could be in the billions of dollars level worldwide. Indeed. So in 10 years' time, things are going well. Might you have longer range and lower prices and a bigger market? Or can you give me a dream? Give me a dream. Yes, of course, of course. So we're here today because we've tracked these technology trends, battery energy density, making possible today, just now, three hours of flight time. But of course, batteries are evolving quickly and what a great thing. And of course, on an airplane, if I design it well, I design the replaceability of the cells, not the modules, not the motor controller and so forth, but I can upgrade my airplane and its flight time by replacing the battery cells within the modules inside the energy saving or energy fuel tank, if you will. So five years from now, 10 years from now, instead of a three hour airplane, I have a five hour airplane. Instead of a relatively slow efficient cruise, I can fly even faster. So as we go forward, the price goes down, the range goes up, and we have an even better solution. That's really interesting. Actually, I'll be cheeky. I could ask questions all day, but I'm gonna ask just one detailed one. On the motors, we've noticed that there's, the original Faraday type of axial flux motor gives you a sort of pancake shape motor and some of those have been used, I think, within a propeller or they're used in the McCarney a huge aeroplane that generates wind energy and a British company makes those apparently. So there is, of course, the Siemens five kilowatt per kilogram, and that's for electric aircraft like yours, and then beyond that, there are people at least claiming anything up to 10, 15 kilowatts per kilogram. Do you see something there for you? Yeah, we've seen, we're in that same range, and of course it's the powered electronics as well. Absolutely. The motor, controller and inverter, previously the size of a large briefcase, and now it's a couple of decks of cards in size of weight. So that's saving weight, it's also a lot of thermal energy, a lot of heat that we don't have to work with as well. So it's not just motors. It's not just battery energy density, it's also the powered electronics that accompany it. So the direction, the technology trends are wonderful, and we'll be building on the baseline aeroplane and getting better every year as we go forward. Just simple things like getting rid of water cooling for motors or batteries or whatever. Indeed. Reducing failure modes, reducing moving parts, reducing weight, reducing space, along a long journey to go. You are the most future-proof person I've ever met. Thank you so much, it's really exciting. It's a pleasure. We'll follow you in the years to come. Indeed. Thank you.
