It is the year 2015 no Hologram, landspeeder or Mega vehicle.
I just watched the movie Prometheus ,Serenity and Star Wars :eek: this weaken and got me thinking we are in the year 2015 no Hologram, landspeeder or Mega vehicle.

From what I read , the reason we don't have landspeeder is jets or fans are
not powerful enough, that make it not safe, hard to make sharp turns, do not turn the dime and hard to maneuver.
Hologram Technology - The Next Future
what we got a crude Hologram
3D HOLOGRAM DEMONSTRATION
From what I read on it, the main problem is laser light does not stop in mid air and this is one of the main problems of making a true hologram like in star trek or Prometheus or the video clip of Hologram Technology - The Next Future .
And we have no mega army vehicles.
Why are we not putting R&D into it?
Do you think any of this may be possible one day? Or do you think this is so beyond today’s technology if it is possible it is 50 to 100 years out.
How many of these threads are you going to start? You have a very confused view of what technology *should * exist simply because you’ve seen them in movies. The answer to this question (and most of the other threads) is simply economics and technology.
For the same reasons we don’t have jetpacks and flying cars - the technology doesn’t exist to solve the problems economically. Just because you want something doesn’t mean it’s going to happen?
Main battle tanks (MBTs) are as “mega” as they need to be. If your asking “Where are the giant robot mechas?”, we don’t have them 'cause MBTs do a fine job of killing tanks and other things. And there’s not much reason to think giant robot mechas would do anything MBTs do any better and some reasons to think giant robot mechas would be much worse at some things than a MBT.
Anybody remember back in the early 90s, there was an arcade street fighter type game that had the fighting dudes on a little holographic stage instead of a vertical monitor. It was pretty radical and tubular.
Mega army vehicles are an OLD concept, not a new one. They’re mostly dumb and uneconomical.
For example, a man named Hitler once thought as you did. The Nazis had a few mega army vehicles that were simply colossal wastes of manpower, money, technical expertise, and material. For example, the Maus and Ratte tanks, among others. And that’s not counting their other mega weapon projects that ending up doing more to help the Allied cause than themselves (due to massive diversions of resources better spent elsewhere).
As noted above, your OP seems to indicate you believe technology in movies is economical, desirable, or sensible. You may want to revisit that assumption.
Star Wars landspeeders hover and propel themselves using sci-fi mystery magic.
We have hovercraft, which aren’t exactly the same thing, and we have flying vehicles that use things like ducted fans for propulsion. Control algorithms for quad-fan vehicles are still being developed, and it was only recently that someone figured out how to safely control one of these types of vehicles if one of the fans dies.
Even if we get the control and safety issues ironed out, these vehicles will never replace automobiles for the simple reason that they require a lot of energy just to keep themselves up off of the ground. This makes them horribly efficient compared to an automobile. So your landspeeder type vehicle will always cost more than an automobile due to the extra complexity, and will always be less safe than an automobile because at some point if enough things fail it will drop out of the air, and it will always cost more to operate, no matter how much technology progresses. It’s no surprise that folks aren’t shoving a ton of research money into landspeeder type vehicles. No matter how much better they get, they’ll never be as good as a simple automobile.
Movie holograms similarly use sci-fi mystery magic. It turns out that light doesn’t actually behave that way in the real world, which causes a lot of limitations on real world holograms.
Mega army vehicles have two problems. The first is the square-cube law. The strength of materials goes up with the square of the size, but the weight goes up with the cube of the size. This is why there are no 6 foot tall insects. Make a tank 10 times bigger, and it will crush itself under its own weight. The second problem is that bigger vehicles weigh more (which should be pretty obvious). This becomes a factor when you want to take your mega vehicle across a river. Current military vehicles are limited in size and weight by the size and weight capacities of existing bridges. Your mega vehicle becomes useless if it gets stuck at the first river you need to cross. Even now, modern armor has to plan very carefully which route they take so that they don’t get stuck at bridges that they can’t cross.
Mega robots are just silly. Walking vehicles can cross terrain that many existing wheeled and tracked vehicles can’t cross. However, most of the terrain out there is accessible to tracked and wheeled vehicles, so it’s only in very limited where a walking vehicle has any advantage. And those areas can be easily attacked via air strikes. On flat land and over much rough terrain, tracked vehicles are much faster and are lower to the ground and can’t easily be knocked over like a walking vehicle can. You’ll never see giant military humanoid-shaped robots. They just aren’t anywhere near practical.
I was reading that they are reaching into air bubbles as a potential solution because the problem with laser is it does not stop in mid air and how do you shape or mold the laser being one of the main problems.
Anyone read up on air bubbles as a potential solution?
Yeah, today’s technology is so disappointing. I mean, we don’t even have an incredible worldwide system of connectivity which has transformed society, accessible through ubiquitous touchscreens and ultra-thin laptops -
So you don’t think fans or jets will get any where powerful enough to make it possible? Have they hit a brick wall? Meaning that fans or jets will not get any more powerful than what they have now. The past 30 years or so fans or jets are not any more powerful than what they have now.
I know with drones cost ,safety and maneuver is mostly fixed now making it possible where in past it was not. Is it possible with advance like in computers to do most of the controlling and deal with maneuver problem of landspeeders?
I know with toy helicopters of 90’s it was hard to control and maneuver problem but now computers do most of the work now where you don’t have to be a pilot.
OK, to tackle mega army vehicles, or superheavy tanks. What’s the purpose of a tank? It has armor, mobility, and firepower. The armor protects the other systems. Mobility is how well the vehicle can move from place to place. And firepower is the weapons systems the vehicle carries. Notice that there is no “bigness” factor. The only reason for a tank to be bigger is if it improves one or more of the above characteristics. So increasing the thickness of the armor means the tank has to be bigger. Adding a bigger engine or larger tracks makes the vehicle bigger. Adding more and bigger weapons makes the vehicle bigger. But bigger vehicles have more surface area, which means you need to cover more and more surface with armor. Bigger vehicles are heavier, which means they’re slower and have more trouble traversing obstacles. Bigger guns require bigger ammo, which means fewer rounds onboard. Plus bigger costs more. And a bigger tank is a bigger target. And if your weapon can already destroy its intended target it makes no sense to make it bigger.
The best tank is one that is as small as possible while still able to fulfill its mission. Modern tanks like the M1 Abrams have really thick armor, powerful engines, and powerful cannons. A bigger tank will be less mobile and have less overall protection. We’ve abandoned the WWII classifications of light, medium and heavy tanks, and now we pretty much only have “main battle tanks”, which are tanks with heavy armament and armor but with the mobility of medium tanks. Tasks formerly done by light or medium tanks are now accomplished with other types of vehicles like wheeled Strykers, Humvees, or IFVs like the M2 Bradley.
The only reason to imagine an even heavier tank is to carry an even heavier weapon. But what would be the point of that? The point of the fanciful Nazi Landcruiserwas to carry around two 280 mm naval guns. But what’s the point of a gigantic cannon if you can’t get the cannon to where it needs to be because the thing can only move at 2 mph and gets stuck in any kind of soft dirt? You’d might as well make an armored pillbox out of concrete instead. Or a towed gun that you just drag along and set up where you need it rather than a behemoth that can barely move. Or build 100 smaller tanks instead for the same price.
We could build gigantic war machines, except it turns out that there’s no particular military or economic reason to do so. The Bagger 288 is a gigantic vehicle that dwarfs the proposed Nazi Landcruiser. The reason we don’t build things like that is that they aren’t very good for their intended purpose, which is to move a weapon to particular places and defend the weapon.
Yes, we can see better/cheaper engines. But that’s not the point. Those vehicles from Star Wars don’t hover because of jets or fans, they hover because they have magic anti-gravity stuff. Invent antigravity so economical we can stick it on a rusty old jalopy on a planet as far as possible from the bright center of the universe, and then we can talk. Until then hovercraft have to use a lot of energy just to keep themselves from bumping into the ground, whereas wheeled vehicles do that for free. Wheels are much more efficient at moving matter from one place to another than other technologies like legs, fans, jets, rotors, or levitation.
Yes, in science fiction movies they show vehicles without wheels, because it looks really cool and science fictiony. But the prop designers who make up those vehicles and the effects artists who make them seem real don’t have to actually build ones that actually work.
Yes, and the reason that in Science Fiction they have holograms that look exactly like real people, sometimes even including being solid, is that actually just use human actors. That’s a really easy way to make your advanced hologram look exactly like a real human.
Sticking an “H” on someone’s forehead and pretending they’re a hologram doesn’t actually make them a hologram.
Exapno Mapcase If I understand reading past threads on the reason why landspeeders in the real world have hard time to make sharp turns, do not turn the dime and hard to maneuver is fans or jets are not powerful enough.
