I am not comparing myself with two bicycle industrialists…I am explaining you in layman terms how ridiculous you make yourself look…as you don’t see history happening in solar flight.

Advancement in solarcell efficiency and weight is incredible….and bringing the ” almost obsolete ” idea of lifting fuselage and high cruising altitude with new materials that make this tick…into whole new level…this can be counted…as I said before….this smaller spanning ( 80 M ) has 4,5 times more cell area ( thanks to lifting fusealge )…and 33% more efficiency in them than Helios which flew 240 km/h at 30 km altitude in 2004.

Anyone with aviation studies behind would see the possibilies in this. It is enermous task to make everything just right, but it does need an attitude change..which I am not seeing unfortunately happening here.

Peace Finny…and live long and prosper !

I should not do this, I will probably regret that I replied, but here goes: I do believe that there are opportunities in all forms of aviation and propulsion. But these will be developed by people (most likely hired by large companies) who have a good understanding of aviation, regulations, aerodynamics, propulsion and aircraft structures, among other things. People who have none, or very little of the above will keep writing on aviation forums. Those who actually work on these things won’t have time, or at least they do not need to bother. I let the audience decide who is making himself look ridiculous…:)

Personally, I don’t see it ever happening with a commercial passenger carrying aircraft.

Of course it will never happen. Best way to deal with this Walter Mitty is to ignore him and let him discuss with himself. Same thing has happened on several Finnish aviation forums, from all of which afaik he has ended up being banned.

More to the point, in late 1945 they could have called the English or American embassies and received all the Spitfires, Mustangs or Thundrbolts they wanted for less than the cost of setting up a production facility.

And with a bit of work they could have found a number of 109s free for the taking (and approval of the allies occupation force, of course).

This may be true, but fact is that Finland was completely broke, and could not afford even almost free airplanes. Also, the view of Soviets had to be taken into account, situation in Finland was really dangerous, there was still a possibility of Soviet occupation. Added to this, the Allied forces (read: Soviets) had grounded Finnish Air Force, all flights required a special permission. After the end of the war there was no more any intention of series production of Pyörremyrsky. The test flights were made more out of curiosity to see how the airplane that had been painstakingly designed and built would actually perform.

Not really wrecks of two. One fuselage + tail section and seven wings, only pieces of engine. Of these it was just possible to restore one complete airplane, not much left over. I agree that it would have been nice to have a Bristol Mercury on the nose, but the Leonides was available and free…

My dear topspeed, I happen to know it is not, nor will be for sale.

I am glad I have a working prototype of my windmill that supercedes all previous VAWT turbines with a margin. Aeroplanes are different thing…they take a team to realize.

I wanna point out that the point in making Solar Impulse I and II was to spread the awereness of the possibilities of solar flight ( and revewables in general ) and brake new boundaries…. I have been doing just that.

Why would you like to brake boundaries…shouldn’t they rather be expanded? 🙂 Would you care to tell how, when and by whom your revolutionary windmill will be produced? And how have you been doing whatever it is you claim to have done? Building RC-models, AFAIK.
