energy source that can last forever and can be implemented to
things we using now, like:
mobile phones and similar devices, so that they will never "low
batt".
Cars, planes, ships do not need to refuel.
anti-collision force field generator on cars. So that when 2 cars
collide, this force field will absorb the impact and make both cars
to come to a stop without any damage. And when a car is about to
hit someone or an object, the force field will absorb the impact so
that it become a slight push on the person.
"hands off" mind controlled devices. e.g. A computer that get
instructions from you thru you mind, not by typing or the use of a
mouse. what you want to type out in your mind will be transmitted
to the computer thru automatically.
travelling thru a new dimension. For now, it's quite impossible for
us to migrate to other planets, cos those near us are believed not
suitable for human beings. going to far planets with space craft we
got now are too slow. even when we invented something that travel
at the speed of light, but our body wont be able to take it. So we
need to travel thru another dimension, which we havent even know
what kind of dimension it is.
Harddisk for human brains. We cant memorize everything accurately
with human brains. If we can add a "harddisk" to our body, then we
can remember every single detail of things forever(unless harddisk
crashed?)
Multi purpose spectacles that can:
change the lens to any color on demand
zoom in/zoom out(work as a Telescope)
take photos
become a "virtual" monitor.(Like Sony Glasstron)
project image(Like what R2D2 did in starwars movie)
