So far nobody human has altered the "time continuum" enough to peer into the future to experience first hand the truth as to what will be. We can only speculate on the technology that will be our future.
Much like a how a meteorologist speculates about forthcoming weather events, it is possible to make good predictions of future events based on past examples of the similar events.
Of all the possible important technologies that will be our future, perhaps the science of time travel will be the greatest quest. The physical simulation of time traveling technology already exist by using audio and visual devices like movies, television and now computers.
Before these "simulation tools" were invented, radio and even book reading used our imagination for time traveling. Stage plays and simple story telling events came before these things.
There are even "designer drugs" that can simulate imaginary time travel - but because they can chemically alter the truth about what is real, they represent a type of technology that may be less than what "will be".
If tomorrow's technology is like today's most popular technology - the science of transporting "the goods", then perhaps whoever designs the most effective vehicle that can transport "the goods" of the future should be a lucky person.
Some persons consider time itself to be "the goods" and would like to design and operate a "time transporting vehicle", like in H.G. Well's "Time Machine" story - however because no true examples of such a fictional craft has ever been documented in recorded history, it seems unlikely no such vehicle will be built in the future.
Computers could be considered a vehicle that transports "the goods" if information is the cargo. Some information does have a real value and, if effectively transported by way of computers, can be important in many industrial or commercial applications.
But for those who need to experience the science of transporting "the goods" in some real hardware using a real vehicle, your quest started long ago and is merely awaiting improvement.
A real vehicle - like a car, boat or aircraft is something that doesn't simulate travel - it actually transports the body and mind to physical places.
Of all types of vehicles, the aircraft is the most effective if the distance is great and the payload light.
Assuming that our future will be mostly "a global thing" and not some Star-Trek "space thing", perhaps the science of aeronautics will play a significant role in our future technology. (Speaking of Star-Trek, the arrow-wing logo design of both NASA and Star-Trek reflect the very symbol of a deltoid sail - the same vectorial design found in the first letter of the Latin Alphabet and aboard early Phoencian sailboats as the Lateen rig.)
Imagine traveling the world someday aboard your personal seaplane and visiting places that you could only read about in a book or see on television. Imagine anchoring your seaplane most anywhere offshore and not having to pay rent to some landlord.
Imagine calling this personal seaplane "home" because the technology that created it has provided the amenities we have come to feel comfortable with. Like something out of captain Nemo's world, imagine a vehicle large enough to entertain - yet small enough to economically operate.
Current aeronautical technology would probably create a seaplane design similar to seaplanes that where created some fifty years ago. Future aeronautical technology should be more simplistic in design as well as cost.
One key design aspect of all future aircraft will probably be the type of propulsion system used. Instead of engines based on expanding gas from burning fossil fuel, future aircraft may use electric motors to drive special props for thrust.
Capacitor-like batteries could power these electric motors because they would be lighter than current liquid fossil fuel technology.
Capacitors, which are lighter than current battery designs, can store lots of electrical energy - however, releasing that energy slowly is the trick if they are to be used as fuel cells in future aircraft.
Perhaps some sort of ram-like kite craft design could be common along our coast in the future.
For those who want to stay closer to the earth, the future of simple nautical technology also suggest a kind of marine craft design that may have more of a utility value than a flying aircraft. By utility value, the meaning suggest space for all that "stuff" that seems to follow us around - like food, clothes, books, ect..
When designing marine craft, the first question one must ask is the craft going to be a mono-hull or a multi-hull design.
For speed and general stability on the water, multi-hull craft designs are a clear winner. Multi-hulls basically come in either a twin-hull design called a "catamaran" or a tri-hull design called a "trimaran".
For simplicity and general utility use, the mono-hull design is better. Mono-hull designs can also be easier to pilot if operating in a tight area like a small harbor or busy dock site.
In either case, at least two methods of propulsion systems should also be considered if this vehicle is to operate safely.
Wouldn't it be nice if your family could live on board some futuristic seaplane or remarkable sailboat while also having access to several computer simulators that allowed "time and space travel" by way of wireless communication and/or special flight-simulator programs?
So whatever the vehicle of transport, imagine the future and invent it!
