Towerman April 15, 2020 03:00 AM Yes, make it to production ! I'm glad they are utilizing a 3 bladed machine, more blades more quiet (and good looks of course) i'm not much of a fan of the bulky aluminum arms, however if they are light enough i suppose i could live with it, the machine looks very practical to work on, that is definitely a plus.Now get those Hydrogen Fuel cells ready and let's wing this revolution into the air ! ! paul314 April 15, 2020 07:53 AM How much armor would you have to wear to survive if anything happened to one of those propellers? guzmanchinky April 15, 2020 09:24 AM How much more dangerous, really, is this than riding a motorcycle at high speed on a crowded Los Angeles freeway at night, and yet we allow that all the time. I think the control systems for drones have become SO reliable since the first ones that one of these machines, if flown carefully and not over populated areas (at first) would be a great start to the personal flight mobility revolution... Tris April 15, 2020 12:46 PM Since this new eVTOL is a prototype its absurdities can be understood like sitting inside a vegimatic. Just hang onto anything not doubly strapped down because this is an exciting open air, up in the air, crotch rocket. I know its only a prototype and soon will have a pod with rotors that stop when the door opens.,, oops,, let's add a hatch door lock, no-opening door for rotor stopping at height, but water landing doors would open in the air tight pod. There are always more possibilities in rearranging the chairs on the Titanic. The future of the air beaters and flame throwers will DEFINITELY be overtaken by; simple, clean, easy, cheap, quiet, sustainable flight as is maximally safe as can be. It will go everywhere anytime with no infrastructure cost so that all of planet Earth's doors connect. This is only possible with true Electric Propulsion using electrostatic fields vs fire and thousands of expensive wearing out dangerous parts.Loz, your readers may want to also know how this future has arrived negating the group think on ion propulsion. My partner patented the MFET transistor as his doctoral thesis. He sold it to Motorola after proving to the patent examiners that the text books were wrong on electrostatic fields back then. He also discovered the Atmospheric Ion Propulsion breakthrough that is very far beyond MITs recent 2% efficient ion wind 1st horizontal ‘lifter' flight. We had a top Electric Propulsion Lab that serves NASA in space prove my partner is correct after their initial skepticism to even look at it. They were simply amazed at it working in the air. It is also far better than working in space by having the ambient air mass to push with down here in our atmosphere. Clean air quiet jet engines will work. It only takes 1 sq meter of eVTOL jet exhaust area to lift 300 lbs vertically and that is with only 25% efficiency while our simulations show much higher efficiencies are possible. The future awaits.

Towerman April 16, 2020 12:33 AM @ Tris Interesting stuff, coming down to practical use my questions will be 1: how complicated is the engine. 2: What is the power to weight ratio compared to electric motors ? Propulsion requirement ?3: Electric motors are known for their great power to weight and size ratio, and economic pricing, how does the atmospheric ion engine compare. i almost feel like comparing an electric motor to a solid state systems as there is so little rotating parts. And reliability is extremely good. Nothing to date can beat the electric motor in terms of size to power ratio, weight and reliability as well as affordability. Tris April 16, 2020 07:12 AM S.Graeme & Towerman, We will be adding more information soon as i defer to my CTO partner when it gets into specific technology. He is busy working on some tech issues at this time. In the mean time you can check out are Corporate website www.charged-motion.com and we welcome comments on that website but for now send questions here after browsing the site. Tris April 16, 2020 04:12 PM Towerman, You are so right about electric motors that is why a Tesla and electric cars can accelerate faster than most 1,000 horsepower internal combustion engines. It is also why we have diesel electric locomotives. But in the air, how do you convert that power into thrust. There is only one way we know of now and that is some form of propeller or fan. In all the eVTOL designs we have seen you end up with a decapitator or a knee-capper. An abstract of an article in Aviation Space Environmental Medicine states,"Rotor blade injuries are an inherent hazard of helicopter operations. Crash-related injuries were not included. During the study period, there were 24 blade strike injuries (12 involving the main rotor), 11 (46%) of which were fatal.If "professional training alone does not guarantee protection from rotor blade injury," how could they ever be made safe enough where thousands of eVTOL vehicles could land in the middle of crowded civilizations.The other problem which is solvable with fuel cells is where do you get enough electricity. All the battery powered aircraft have a range of around 50 miles. If Tesla is having trouble selling cars with a 325 mile range, the market for a 50 mile range vehicle with the same recharge characteristics will be even smaller.Answer to Graeme, There is a massive amount of information available on our website and here are some videos prepared by us now on Youtube that may be of interest to you. https://www.youtube.com/playlist?list=PL39zpVaxj5Z6a3FhOyZEFFjv2hf9ktE5o If you would like to contact me personally or my chief technical officer you can send an e-mail to email@example.com.Tris EmmanuelGrayton April 17, 2020 01:19 AM @Tris This sounds like an interesting piece of engineering.Who is your CTO? What was the name of the propulsion lab that tested your ion propulsion design? Do you have a prototype? Tris April 17, 2020 08:26 AM Emmanuel, All the information you seek is on our website [above] plus much more but that lab is under NDA for now. Soon we plan to publish a series of articles for public consumption which will identify that lab. I will also use this post here to note our crowdfunding campaign shown in some videos [above] is now closed due to that site's administrators having "ion wind group unthink" so they did not publish our project. The few donors we sent there. Even our search key words failed to locate our project consequently no donations, but still is there showing a gallery, a story and all the videos on youtube. To see it search "The I-Jet Future indiegogo". You can skip over any redundancy if you look at it all.
