Says there are only 40 some in california.I think of the 400 hydrogen refueling stations all but 4 are in California?
Yes 40 got dyslexia I guess or something. I'll edit.Says there are only 40 some in california.
Different sources cite upto 500 worldwide in

True.... I am personaly really sad because this "investors baits" are damaging image of electric aviation.Show us the flying protoypes. There's a lot of talk about this stuff happening tomorrow, but don't you think there would be some flying prototypes first? Pretty hard to keep this sort of thing a secret. There is money in news stories, and some journalists are good at smelling out this sort of thing and getting actual pictures of it in flight, not the CGI stuff we see on the websites.
The second article about the 1500 hydogenYes 40 got dyslexia I guess or something. I'll edit.
To develop effective VTOL aircraft is hard, as the performance for cruise is driven by L/D, that means large wetted aspect ratio - slender wings, low drag; and effective propulsion at cruise speeds. For hovering performance, the aircraft needs low disk loading, otherwise the power demand is very high. However, low disk loading means large rotors, and large rotors are inefficient for high speed operations. Several VTOL aircraft configurations are coping with this conundrum, Edgevise flying rotors - typical helicopters and multi-copters - low L/D, retreating blade stall; lift + cruise systems, stopped, stowed, folding rotors - adding drag and ‘dead weight’; Tilt wings and tilt-rotors - they are a compromise, the prop-rotor is too small for hover, but too large for cruise. Adding to this is the fact that wings are at best ‘dead weight’ in hover, but practically is the source of unwanted flow interactions - e.g. impingement, fountain flow.Show us the flying protoypes.

working on it; also I can compare it to NACA's experimental data of the channel wing (PDF) The lip wing system, an analysis based on channel wing experimental databeautiful cad, engineering and model work.....I hope you can calculate the scale effects differences with models before you invest too much money in full size......
This stuff fools people like a couple of the posters here, just like Moller's endless promises fooled some of us 40 and 50 years ago. The old guys then said "Yeah, sure" when they heard us talking about flying cars. Crusty old curmudgeons stuck in the steam age, we thought.True....

I will try and fix that.Let's move this to a discussion of serious matters.
The weird carriage returns in Dog's posts are almost certainly an interaction between his posting platform (phone, tablet, computer, etc), settings buried in the browser or other software he's running (which likely he never touched), and the forum software. I've seen it happen to others on other forums; I've even seen it happen to my own posts.
And ethanol isn't that bad an idea or a political thing (but making it from corn is both, if I can believe what I read on the internet).
edit: obligatory & explanational ;-)
Yep. That's the inescapable need for a bigger tank for the same power/range. Alcohol has some lovely properties. It's resistant to detonation, so you can turn up the pressure, either with higher compression, more boost, or valve manipulation. Or all of the above.Or is alcohol less energy dense per pound.
Must be a slow burn. Nothing in the news about the world on fire. I did see an article on the intro of the Tesla Plaid S though. The reporters seemed intent on pointing out that it was overdue and over budget, but that could be said about so many products these days. 390 mile range and can recharge for another 187 miles in just 15 minutes. I like the recharge time, but they didn't mention at what speed that range is obtained. It also noted a longer range version is coming, but it'll be slower. I don't think that's necessarily a bad thing when you consider realizing all the "quickness" of the Plaid S would usually involve breaking the law and endangering lives. Slower is far more practical, as long as it isn't too slow.Seems Archer Aviation is going to publicly-unveil something that's really going to set the world on fire......
