What if the first few commercial airliners experienced disaster, and the airline industry never took off (no pun intended. )? We might be jetting around on superfast mag-lev trains that line the country like highways.
Evil_evol said:I agree. the nick of fate often seems to be underestimated in most TLs i read. Just take Titanic as an example; the sinking of the ship, and the sinking of the development of the industry in question was impossible to forsee (yet percautions could have been in place, yes). I mean, logically, with the prestige and money that was to be made from that method of traveling, just having the development stop overnight (more or less), granting the sucsess of other menas of transportation, such as by aircraft, would be considered highly unlikely if it was presented in a TL.
Paul Spring said:If I understand you correctly, I also agree. The success of any particular technology is not preordained by its efficiency or utility. Just look at the wheel (or lack thereof) in the precolumbian civilizations. This was particularly true in the late 19th-early 20th century when so many new technologies were being developed at about the same time. As I've noted in other posts, a delay in as little as 5 years in the development of one (like airplanes) could have led to the victory of other (like airships). Once the direction of an industry is set and gets its internal momentum (infrastructure, subcontractors, education,training,acceptance, etc) it becomes harder of another to supplant it. And that leaves out the very real element of conspiracy and collusion. The victory of IC engines over steam or electricity as prime mover for privale cars is also a case in point
I'm inclined to disagree. The wheel isn't nearly as useful when you don't have any large draft animals, which the precolumbian civilizations of the Americas didn't. Even if airplanes had been invented 10 years later and airships had been more widespread in commercial use, the far greater speed of airplanes would have eventually given them dominance in the market for carrying passengers - though airships could still have a large niche market as floating luxury cruisers. Internal combustion engines have one huge advantage over steam - you can start moving as soon as the engine is turned on, rather than having to wait 20 or 30 minutes for steam pressure to build up. The problem with electric power has been that most batteries until recently have needed to be recharged every few miles, while you can go hundreds of miles before having to refill a large tank for internal combustion engines.

How would a clutch and geartrain stop adoption of Stirling engines, compared to the much heavier (and more dangerous) steam engines at the time?Roland Wolf said:Stirling engines-while very efficient-share one vice of steam engines:they are quite heavy. For example the WhisperGen, a Sterling power generator sold widly in Australia, weights 190 kilogramms for an output of 4 kw.
An you need a clutch and gearttrain arrangement in order to use it. So in the 19th Century the steam engine rightly succeeded. A more widespread use of Sterlings could cause other effects as well. They are very interesting if used in Submarines.
chrispi said:My "For Want of a Nail" TL has automobiles with the driver's seat right in the middle. Why? Because countries, unlike OTL, disagreed on whether to drive on the left or right side of the road. How does a car inventor cope with this, use two steering wheels and two sets of floor controls? This inventor wants his machine to be street-legal on both left-hand and right-hand roads, remember, so he settles on a compromise: the driver's seat is centered.
(This arrangement has the added advantage over OTL of allowing the driver to step out on the sidewalk and away from traffic!)
