On nearly every point you have given the wrong reason regarding the debate that the Amerika bomber could not have become a viable concept.
No, we are discussing RL possibility here. In rea life - if the Battle of Britain had been won and so resulted in the end of strategic bombing of Germany, German industry and all would have managed far more than it actually managed. I trust this is not any stretch of the imagination. The point is that the successful Allied strategic bombing is the reason the Amerika project was not realized... and not the technical reasons you offer.
... but even without the allied strategic bombing campaign,
Precisely where you and Mr_BOnarpte lose your debate. As RL never gave that chance, you fail to compensate your predictions for what would have occurred if the strategic bombardment of Germany is stopped.
which was probably more important for its indirect effects -
Maybe you should ask Curtis LeMay or "Bomber Harris" for their opinion?
i.e. forcing some dispersal of production
Some dispersal? How about most of the final industry burrowing into tunnels to be able to continue any production.?
and allowing the Luftwaffe to be chewed up by long ranged fighter escorting the bombers,
This is irrelevant to the fact that such would not even have occurred had the strategic bombing been stopped. The final demise of the Luftwaffe is not at all an argument in your favor that the America bomber was a failed technological concept.
the Amerika bomber was never a practical proposition for Germany.
Yes it was practical when design work was started in early 1942 and the renewed Barbarossa spring offensive indicated that the war on the east would be won. It only became an impractical proposition once the Allied strategic bombing of Germany intensified enough.
Even if some sort of nuclear device had been practical for them and they didn't have the resources, as well as the wrong turnings they too, it would have be dubious.
Using the word "practical" again here hardly fits. Perhaps you would like to try instead "possible" or "not possible" because what is really practical is very dependent on the success of the Allied strategic bombing campaign. A thousand more Messerschmitt's would have been infinitely more "practical" than any effort spent on a future nuclear bomb, but there is no doubt that Germany would have invented the A-bomb if time had allowed it. If the strategic bombing campaign had not crippled Germany so massively, Germany could also have mustered the equivalent of a Manhattan Project investment. Of course, things like losing the heavy water to the bottom of a very deep lake did indeed present "wrong turnings"... if that is what you mean by that phrase.
Conventional bombing at that sort of range across the Atlantic against a well equipped air defence would have made the sort of losses the allied bombers suffer in RL look trivial.
Oh very true. Nobody seriously thought that one would fly some 500 pound bombs across the Atlantic to annoy the Yanks. Germany already had a much better weapon working that was equivalent to one bomb but could sink a whole ship. Of course the Amerika bomber concept was part of the "Wonder Weapons" package that included a whole new class of bomb.
Plus such a massive project would mean a hell of a lot of other stuff wouldn't have been developed.
Not true. Again you don't conceptualize that there would have been much greater production with the strategic bombing stopped. Of course, the project was too massive given the actual reality that was later-war era Germany... and it is astounding that the project even got as far as it did. But that is not the point of the debate. Mr_BOnarpte's use of "feasible" is the debate. Obviously it was not feasible given the RL rubble of Germany. But, as I said, change fortunes to stop the strategic bombing of Germany and you should be able to see a most already advanced concept of the Amerika bomber succeeding.
Even the B-29's the US developed by 45 were a huge drain on their resources including in manpower to develop, produce and maintain them.
But then nobody was bombing the US factories. Your comparison is not valid. Germany had the industrial base (before it was crippled) to build Amerika bombers. In fact they did build some.
Something far more ambitious such as the Amerika bomber would have been well beyond the German capacity unless they pretty much totally cut out say all armoured production and a few other things.
That is just not right. Nobody cuts out all panzer production to build aircraft. You think saving on armor and tank treads somehow morphs into more aluminum for aircraft skins?
Well, with the length of the many points already disputed, let's j not side track to other examples.
Apart from other problems the Germans lacked access to special metals that meant their engines were often very short lived and never as reliable as the British jets.
In all of your long and I am sure very considered post - this is where you quite by accident hit the only truly valid reason why the Amerika bomber concept might have failed. Your point - applied to the ME-262 - is very true... and would have been a very serious short coming for trying to fly any aircraft trans-Atlantic. Lack of enough of the rare materials needed to fit the endurance requirements of the Amerika bomber concept might have caused concept failure because enough bombers may never be built.
There were a lot of technological ideas in Nazi Germany but many were never anywhere near development simply because of the huge resources that it would take for developing them.
Not true if applied to the America bomber. There already were flying prototypes and just like the USA B-47 program evolved into intercontinental B-52s, Germany was headed down a similar road. Maybe the problem is with your use of "anywhere near development" because, as stated, they were indeed being developed.
Even if Germany had somehow conquered Britain and much of the Soviet empire this might well have had limited effect because of the inefficiency of the Nazi regime.
Come on now - winning 2 wars and the only remaining front being with U-boats results in "limited effect". I think I will skip even addressing the 2nd bit.
A few ideas were taken up by the allies and Soviets but there's a world of difference between a good idea and getting it from a sketch on a napkin to an actual produce in general production.
I find this somewhat insulting to the German research program. Maybe you are overly influenced by the "tech sketches" you see in AoD? If you check your history, you should learn that the good ideas (turbo jet engine, swept wing design, ballistic missile and more )all were developed by Germany... and taken by the Allies to help them advance. Germany did not have sketches as you imply but jet fighters flying, missiles falling on England by the hundreds, and - actually - America bomber porotypes that were being tested (flying in the air) to help further the research for the design concept that was envisioned with that project.
All in all, I think your debate points fail (except one).
