There is a very practical reason why a such a vehicle will never happen, even if the inherent inefficiencies can be ignored, for example by having access to an advanced source of energy.
The reason is that, if you’d try to park your land speeder, supported on a column of high velocity air jets you’d blow any pedestrian around you head over heels and probably wreck whatever shop front you were going to, not to mention the danger from debris being flung at high velocity hurting people and property.
Just try to picture a Harrier jet landing on a busy city street. Not pretty.
MegaVehicle: 2006 Dodge Ram offered a MEGA CAB on a truck, so MEGAVEHICLE.
Every persons vision of the future is different and just because it doesn’t meet your definition of the future doesn’t mean we are not taking steps to what you are thinking.
It looks like they are making some progress on hologram technology. I wonder how long to hologram technology is like https://www.youtube.com/watch?v=wwUcZMfmj-Q
One just requires energy. The other requires a supply of all the molecules needed so that you can move them around. Totally different concepts. The first is magic. The second is just ridiculously impractical.
Exapno Mapcase I’m not sure what you are trying to say. Can you elaborate on this.
My understanding is the star trek replicator has a database of all known matter and uses energy to turn into matter.This requires infinite energy from my understanding. More energy in the normal universe,
A molecular assembler is sort of like a 3D printer, only it moves molecules around.
Remember scientists have moved molecules and atoms around in the lab to build toy car and toy guitar on a molecular scale. The problem is it is very time consuming and hard to do and to scale it up would be very time consuming . We have no machine that can just do it on its own and not to say the computing power is too crude.
A star trek transporter as some problems too. No one knows how to transport some thing. Not only that, but a transporter as other problem too it disassemble you( killing you ) and than assemble ( a copy of you ) .
This is one technology even if we had it no one would use it because it disassembles you ( killing you ) and than assemble ( a copy of you).
If some one finds a way to build quantum computer than computer power would be there for new MRI machine that can scan your body with so much detail all the way down to molecules and atoms.
If some one finds a way to build a machine to move molecules around it will require computing power of a quantum computer to keep track of the molecules .
But unfortunately star trek transporter will never come to be because it disassembles you ( killing you ) and than assemble ( a copy of you).
Microsoft has a nearly real-time speech-to-speech translator in the works. You speak one language and it translates and repeats what you said in another language. They have demonstrated it several times using several different languages.
That vehicle may be powered by jets, but it still has wheels. The only reason it has wheels is so they can still call it a “car” and thereby break the land speed record. There are all sorts of real-world jet cars and rocket cars, the disadvantages of which for day-to-day use should be obvious.
If you just want a hovercraft–a vehicle without wheels that hovers a bit above the ground, we have plenty of those, they’re called hovercraft. If you need a vehicle that can operate on both land and water they sometimes make sense.
None of these work like Star Wars vehicles, which require antigravity. The reason we don’t have such vehicles in real life is that we haven’t invented antigravity yet.
From what I understand a star trek replicator has a database of all known matter and uses energy to turn into matter. If you need water it as two hydrogen atoms and one oxygen atom.The star trek replicator uses energy to form matter.
A star trek replicator does not move molecules and atoms around like a molecular assembler.
Most things that get called holograms aren’t actually holograms. Of real things that get called holograms, they’re usually either just images projected on a screen like at a movie theater, or (if they’re fancy) reflections in a mirror. The rainbowish eagle on your credit card, though? That is absolutely a true hologram. It’s not our fault that you think the word “hologram” means something else.
Well it’s Navy, not Army but a Ford class nuclear carrier is pretty mega. And they’ve already successfully landed autonomous drones on them. We have devices in our pockets that can access almost the sum total of human knowledge quickly, we have autonomous hunter killer drones flying in the skies. We certainly live in a science fiction reality already, it’s just that the the way it’s going it looks more like the future in “Terminator” than the one in Star Wars or Star Trek.
I have an app on my iPhone called “Word Lens” that instantly translates written words through the camera. It translates between English, German, French, Italian, Portuguese, Russian, and Spanish.
It’s not on par with a Star Trek universal translator but it sure looks like magic. It’s not even a new app, I’ve had it for years.
ETA: I don’t see anyone mentioning 3D printing, that’s like a primitive replicator.
