We all know about teleportation from Star Trek: it's where a special ray disassembles you into your component protons, neutrons and electrons and then carefully reassembles you in some other location, thus completely doing away with the need for costly special effects, as well as — in theory — the need for things like video phones.

In actual fact, the brains at a place called the Joint Quantum Institute at the University of Maryland have already taken a step towards real teleportation. So far they've only transferred a quantum state between two atoms one meter apart, and with an accuracy of only 90 percent. But hey, it's a start.

There are actually a lot of real-life companies making flying cars, but, somehow, the things they come up with just don't seem as exciting as we thought they were going to be.

This flying car is made by a company called Moller and is their model from sometime in the 1970s or 80s, judging by the size of the chap's lapels. Their most recent version can lift 10 feet off the ground, fly for 90 minutes at a time and costs more than $90,000.

A company called PAL-V Europe is also promising to make a flying car, but their model still seems to be at the computer-graphics stage.

It's time to take transcontinental passenger flight to the next step: a Buck Rogers-style rocket that flies 700 miles off the ground and can take off from Berlin, cross the Atlantic and land in New York City in less than an hour.

This concept image dates from 1931, when the idea of German rockets raining down on New York still seemed like a neat idea.

In the future, as seen in 1923, there will no longer be any need to pop round to Boots to buy slices of styrofoam filled with an unidentifiable food-like material. Instead, robots will deliver it to you on a wheeled tray as you sit rigidly in a hygienic compartment surrounded by flat-panel displays advertising cheap rocket trips across the Atlantic, the latest models of flying car and the VideoPhone 4.

Gravity is the enemy of a youthful appearance. In the future, there will no longer be any need to embed artificial materials such as Botox into the skin to 'lift' those annoying wrinkles, according to this 1935 article. That's because regular sessions of being thrashed around and around at dangerously high speeds inside a centrifuge will mean that you always feel hale and hearty.

Imagine a future where the internet and teleworking are no longer necessary. Instead, we all own gigantic caravans the size of juggernauts, filled with all the conveniences of home and jammed with 1950s-style furniture and office equipment.

This handy living-working capsule will constantly transport us and our families around the world from one business meeting to another. For entertainment all we will need to do is peer out of the observation turret and try to figure out where we might happen to be at that moment.

Enclosing major cities under plastic domes is just a good idea, some thought in 1968. Why? It doesn't matter. Let's just do it and we can figure out a good reason afterwards.

Getting ready for work in the morning can at times be a dull chore. The solution is obvious: we need sinister insectoid mechanical servants to cosset us at all times, combing our hair, putting our clothes on for us, shining our shoes and feeding us protein drinks, while they prepare our jet-car for takeoff and plan our next holiday at the sea-floor resort. Thank you, sinister insectoid mechanical servants.

This story from 1957 predicted that we would all own these robots by 1965.

Once every inch of the Earth's available land surface is covered with domed cities, 16-lane motorways, robot-operated protein farms and nuclear power plants, we may feel a longing for open space, green fields, fresh air and a natural way of life. But where could we possibly find these wide open spaces, these unspoilt vistas? Simple: inside a giant rotating orbital space colony.
