What you said has to be one of the most outlandish failures of logic I have personally have ever seen. You're saying that War equals progress. The conditions and events of every War is extremely variable as well as the outcomes. Just because there is War does not therefore necessitate technological progress.
We're talking about planet-rattling World Wars here, though. And the track record of
those is clear enough: 100% of them so far (that is, both of them) have been associated with incredible technological progress. It would thus be fully justifiable by historical precedent to follow the dramatic precedent and portray world wars as beneficial to the winning sides (those being defined rather loosely and sometimes counterintuitively - West Germany and Japan in WWII, for example).
Note that the 600 million dead apparently never hurt places like New Orleans, San Francisco, Boston or Paris, which still sport their original, pre-WWIII buildings - in happy mixture with modern ones, which proves that the old ones haven't been rebuilt to preserve a historic milieu. Nor do we have indication that the 600 million dead would have as much as inconvenienced Bozeman, Montana. Perhaps they all died in China (as our only glimpse at the so-called post-atomic horror featured Asiatic faces)?
Why fantastically efficient? What lead you to that conclusion?
Simple knowledge of rocketry. Neither
Botany Bay nor
Ares IV as portrayed would be viable spacecraft for achieving "Mars in a week" unless they managed to squeeze significantly more power out of a kilogram or cubic meter of fuel than today's designs. Moreover, nothing we can even imagine today could do what the engines of the
Botany Bay eventually did - propel the ship to distant interstellar space, apparently at such high relativistic speeds that the 270 years of transit time-dilated to mere 200 years of cold sleep for Khan.
Clearly, the Trek mankind has had conquest of the Sol system down pat for twenty years by now, and must be in possession of amazing technologies, quite regardless of the fact that many examples of that mankind still suffer in "sanctuary districts".
Flight is far from space flight. One requires merely speed and lift. Space flight requires life support, avionics, re-entry protection, radiation protection, etc and a high level of precision.
All of which are cheap spinoffs of a technologically advanced civilization. A medieval engineer, no doubt just as smart and skilled as his 1950s counterpart, could not have cobbled together a crop-dusting plane because the local drug store didn't sell fuel pumps or high-grade hydraulic fluids. The 1950s engineer couldn't build a tourist rocket because his mail order form didn't feature tick boxes for composite hulls and laser gyros. And Burt Rutan can't get an inertial damper from EBay yet. But the trend is clear, and Cochrane could have preordered long before FedEx got nuked. Assuming it did get nuked, since the track record of devastation is so ambiguous.
I said "could". Which I know because the possibility is inherent in the structure of Star Trek: mankind there is making much faster progress to space and the stars than mankind here. Slightly assisted by the fact that their universe is easier, of course - but probably also assisted by the fact that their universe happened to feature a bunch of supergeniuses in the 1990s, no doubt giving a boost in key military technologies that soon thereafter sept spinoffs to the civilian sector.
Ah, good old Memory "Often Wrong" Alpha...
Never trust that source without checking. Much of the stuff on Ares there is bullshit. Or "not connected to what was seen or heard on screen", to put it more nicely.
Except by Pattern. Pattern shows the intermix chamber is an annihilation device.
But I thought you didn't believe in Pattern? That is, WWIII must be different from WWI and WWII; garage building in the 2050s must be different from garage building in the 1950s and 2000s; and mankind's steady push into space must absolutely have gone retrograde in the 2050s so that not only would the fancy spacecraft all be destroyed in the war, the art of building them would somehow be lost as well.
Don't let Star Trek hijack perfectly commonplace words. Cochrane would know "intermix" from his own context, namely that of the well-equipped bar next to his silo...
FUEL is the largest concern of space flight because is expontially effects the size, speed and design of spacecraft.
Yet you pay no attention to the obvious lack of fuel volume in the DY-100 and Ares designs?
Like
T'Girl said, fuel wouldn't be much of a concern for Cochrane because he wasn't going for endurance. Rapid release of energy would be his goal, and the two things that can do that today in a controlled manner are chemical mixers and electric capacitors.
Whether fusion would be up to the task depends on the method of energy tapping utilized in the mid-21st century of Trek. Today, we intend to capture fusion energies by running the heat through steam turbines, just as with fission; that's no way to energize a hungry warp engine. Cochrane's peers may have come up with something better, but it's also possible they haven't. In which case something more akin to how we power high energy lasers today would be Cochrane's first choice.
