Technological Flights Of Fancy That Fizzled
prostoalex writes "MSNBC's Alan Boyle takes a look at seven futuristic dreams for the past that never managed to materialize into anything substantial in this 21st century. At the top of the list are flying cars, with personal jetpacks, passenger airships, supersonic commercial flights, space travel and colonies, with propulsion breakthroughs completing the list."
Surprised that's not on the list anywhere ...
It was a pretty good article, but very weak on the Hindenburg details, many people seem to aggree these days that it was not the hydrogen that exploded, but the fabric.
Of course the Hindenburg is a fine example of how important a picture could be. Only thirty seven people died (97 lived), yet the burning fireball caught on film managed to kill decent method of long range travel. Of course there are a couple of other problems with airships, like they don't do too well in strong winds, and they take a lot of "man handling" at the field, but in some applications they might make good sense.
The grass is only greener, if you don't take care of your own lawn.
Interesting that all of these failed technologies are transportation based. Good thing we invented the SUV instead of personal jetpacks, or some nonsense.
...the prediction of hundreds of cable channels did come true and yet there is still nothing on.
It's funny how when you think about the past, you seldom think about your expectations at the time for the future. This article really made me think about how no invention becomes reality simply by virtue of some sort of inevitability. Money, the market, luck, and the tides of history all play a part in determining what will make it and what won't.
Somehow I don't think I'll ever get to use a Transporter either. Dammit!

I bought a stack of Popular Electronics magazines from the 70's on ebay a few months ago. There's some great "upcoming technologies" articles.
In the days before the magnetic strip, they predicted credit cards would have a holographic image that optically stores the credit card number. The card projects the hologram onto a sensor which reads the number into the computer for processing.
In the letters to the editor section, someone was wondering if it was worth taking a course in TV repair because with the release of the Phillips Modular design it will be easy for anyone to fix their own TV so the repair industry would become obsolete.

Given the uproar created by the Segway, its not surprising that flying cars and jetpacks never "took off." This is not an issue of what engineers can do technologically, but an issue of what society says they can do in public.
Two wrongs don't make a right, but three lefts do.
But how about totally revolutionary physics -- the kind of thing we see in "Star Wars" or "Star Trek"?
:)
You mean the kind of revolutionary physics that allows multi-ton objects to turn on a dime at insanely high velocities (with nothing to "push" against) without tearing themselves apart, and also without expending the energy of a small nuclear blast in order to do it?
Endless arguments over trivial contradictions in books written by ignorant savages to explain thunder in the dark.
Truthfully, this is the biggest dissapointment out of all of the things that were listed as failed. Though, I'd like to rejoice at the idea that the military's still pushing supersonic travel, it doesn't make me all that comfortable (for more reasons than a simple sonic boom). Seeing the Concorde go, seemed like seeing a portion of the future dissapear in front of us, and all because of a couple accidents. Of course, coincidences are hardly excuses, but still, I'd like to have seen these machines continue for a while.
I can just imagine that one day I'll have the ability to be connected with family across the globe in real life, like I'm connected to them virtually. I can just hope that what the military researches, at whatever cost it may be, will eventually reach the mainstream consumer.
You know what irritates me? Pres Kennedy said we're going to the moon, and 8 years later we did it. We landed Humans on the moon, we walked around, planted a flag, parked a hoopty, took some snapshots ........ and then .... We. Never. Went. Back.
WTF? Thirty friggin years later and no one has ever gone back? Instead we're pouring money into a useless space station for political feel good points.
There are enough metals, water, and WEALTH orbiting just past Mars to make every living Human a trillionaire, and we're still fighting wars over oil, diamonds and pieces of land measuring a few hundred square miles in size.
All the eggs are still in the same basket. It's only a matter of time before a great big rock flies into it and breaks every damned one of them.
Only on
We have flying cars (1). They're called "Helicopters". They're expensive because they aren't mass produced on the scale of cars, which is because fuel costs are prohibitive for wide-scale use.
We have personal jetpacks (2). Earlier attempts ran out of gas too quickly to be useful, but this appears to be a solved problem now.
We have supersonic planes (4), but the fuel costs are prohibitive for commercial travel.
We have the technology to put people and equipment in space (5 and 6), but fuel costs are prohibitive for anything other than military applications and government funded scientific research.
The aerospace breakthroughs that occured in the early 20th century were all driven by the availability of mass-produced gasoline-driven engines, which brought the cost and weight of energy down by a large margin compared to coal burning steam engines. Jet and rocket engines became practical in the 30s and 40s, producing another round of breakthroughs. Steam engines lead to a round of breakthroughs when they first became practical.
The reason we've only been seeing incremental improvements is because we're still using the same basic technologies. As soon as a new power source which allows more power for less money and less weight, we'll have flying cars, personal jetpacks, space tourism, and space colonization.
I don't think it'll be fuel cells, since there's no order-of-magnitude improvements in power density there. My money is on a breakthrough in Uninterruptable Power Supplies.

I for one am glad the flying car has never made it. Some people can barely keep their cars on the road. Imagine if a distracted individual talking on his/her cell phone, screaming at their kids, eating a meal, and watching a DVD movie slammed into a chemical storage tank.
Well, there's spam egg sausage and spam, that's not got much spam in it.
Given the vast energy required for most of these devices, their approach really isn't that practical.
If you think that modern cars get bad milage, just imagine the fuel bill for one that takes off vertically. Likewise for the personal jetpack and for supersonic flight. Fuel cost is also a big problem in space exploration.
I'm guessing that these technologies will find a niche if, as - and when - renewable energy costs come down a couple of orders of magnitude. Only then will these extravagant methods of transportation be practical and likely only as niche markets given that there are vastly more efficient ways of getting from A to B.
But in many cases technology has already eliminated the need for many of these advances.
For instance, one of the driving forces behind supersonic flight were the "high-powered" executives who found that they could attend two board meetings on opposite sides of the atlantic on the same day - and be home again in time for dinner. But with advances in broadband teleconferencing, they don't even have to leave their home.
Tesla and many scientists who furthered his work kept announcing that the fantastic technology advances seen in their time were just the beginning. Think about it: in a few decades we got phones, radio, generalised air traffic, television, nuclear power, premices of computers, and then ... it stopped.
What common appliance do you use everyday, that is not just an incremental improvement of the some invention, or mix of two+ inventions, discovered before the end of WW2 ? What happened to inventions since then ? There are no general public usage of supraconductors, of the technologies that put a man on the Moon... Even the Internet is just an improvement of commuted networks, though it is binary instead of analogic.
The only major breakthrough that could plausibly make its way into our day-to-day lives is hydrogen fuel cells. Where are all the other Breakthroughs ?
Maybe we deserve this world ?
A 1/3 chance of surviving a jet crash? Nope.

The new airships like the Zeppelin NT and the ATG machines can use vectored thrust to reduce the number of ground crew required, the power/size ratio and construction methodology is also enough to allow flight in much stronger winds than the first generation machines at the start of the 20th century. They can operate within similar weather conditions to other aircraft like helicopters and light aeroplanes.

The airship wasn't killed from long range travel just by the film of the Hindenberg disaster, though it certainly didn't help. The much higher speed and lower cost of the aeroplanes did more damage and I don't see that changing for A->B travel in the near future.
I think however there's a niche similar to the one cruise liners operate within which I believe airships could fill. A world cruise on something like the Hindenberg would be absolutely fantastic. Then there's the obvious military/police patrol and observation platforms.
Government of the people, by corporate executives, for corporate profits.
Do you recall an airline company called "Pan Am", the biggest one of their time?
They were the victim of this little incident above and in Lockerbie. You may want to check out the results for Pan Am shortly afterwards, to see how well this turned out.
We're getting off topic here, but PanAm filed for bankruptcy because of airline deregulation.
In the 1980s the Civil Aeronautics Board (CAB) was shut down. It was the federal regulatory body that regulated airlines. The CAB was not the modern FAA, but instead regulated such aspects of the airline industries as prices, routes, and destinations. PanAm was the greatest beneficiary of the CAB, considering it was the largest US airline during the 50s through the 70s. PanAm basically didn't have to compete with rivals because the CAB's regulations basically guaranteed it profits.
In the past the only way an airline differentiated itself was with service. Only a few people could actually afford to fly, and as a result airlines were sort of a "luxury" form of travel with full service (throughout the cabin) and amenities.
The the CAB was dissolved airlines realized that they didn't have to compete with service, but could do so with prices. For a while, it seemed like airlines were popping out like wildflowers (remember TrumpAir?). Again, as a consequence of deregulation consumers had more choice in their airlines, more choice in routes, and more choice in prices.
When the things change, usually the largest and most entrenched entities are slowest to react. PanAm basically didn't know how to compete in this new environment. Airlines lowered prices to the point where anyone could fly. Today flying is not reserved for the privileged few but to most everyone in the US. In the early 90s, PanAm basically found itself barraged with "new" lower cost airlines and went out of business.
Some big airlines managed to survive thanks to smart management. American Airlines today is the one of the world's largest carrier. Some other big airlines wound up dying but not dead. TWA is a shell of its former self. The big winner in the industry is Southwest, whose low cost model is replicated with other airlines such as JetBlue.
Many of the airlines that sprung up thanks to deregulation no longer exist. Trump's airline is one example. When all the cards fell into place only about ten major airline remained in the 90s. But even so air travel demand kept going up, and prices still went down. Every major airline today has filled for bankruptcy in some for or another (United, American, Continental, US Air, Delta) or bought out by another airline (US Air, TWA). Ironically Southwest, although a "discount" airline is 1) the most successful 2) posts profits even post Sept. 11th.
Many people have complained that airline deregulation ruined air-travel. I don't believe this is true. Complaints are usually about travel delays, long lines at terminals, passengers being treated like cattle, and that was before Sept. 11th! [With airport security a big buzzword today it's probably even worse.] But keep in mind what has happened thanks to deregulation. Airlines are flying to more destinations, especially those with large markets. Airline prices have dropped to almost nothing compared to the past. Passenger ridership has increased significantly in the last twenty years. I would contend that most of the problems seen today with air-travel (not a result of security measures) are a result of the "old" regulated mentality that some management still have.
