Why can't we scoop energy from space into our crafts to provide
propulsion. Space is full of energy!!!
Why do we have to use power plants designed on Earth?
It is apparent to me that for the safety of the piloted craft, we wrap
the craft in a force field and protect the astronauts, thus we have to
carry our fuel in some form on board the craft for these missions.
The same way we take solar energy out of the air, we can take space
energy out of the air. We are stuck on power generation instead of
using the available power in our various environments.
We need to think of a method of capturing all that energy in space to
fuel our craft, not just solar.
Any ideas?

Just FYI...
"Star Trek" is *fiction*. ;-)
We don't HAVE (yet...) inertial-dampeners, zero-point generators,
or impulse drives.
If they're developed in the future, that's great... but for RIGHT
NOW, we have to make do with what we have.

Im afraid you watch too much television. Try spending time reading some
books on physics, math, and chemistry. Then people here will be more
able to answer your informed questions.

..Where is all this energy?

What other energy is there in space? After sunlight/starlight, there's
no energy of any significance (unless you want to play games with
trading motion of a spacecraft for power in a planetary magnetic field,
which is just another way of getting energy out of the spaceship's fuel
tank.)
Unless you can name this other mysterious space energy, you've got
solar, and solar is limited.
In Earth orbit, space stations need huge, clumsy solar panels to
deliver a few score kilowatts. A nuclear reactor totalling a few tons
can deliver as much power without the many problems of solar power.
Beyond Earth orbit, solar energy disappears pretty quickly. Twice as
far from Earth - not even to the asteroid belt - and solar energy is
only 1/4th as intense as it is at Earth orbit. By Jupiter's orbit,
solar energy is 1/25th as intense as Earth orbit, which means you need
acres of solar panels to get anything approaching the power of a small
nuclear power plant. By Saturn's orbit, solar energy is 1/100th as
intense as Earth orbit. It's downhill from there.

Maybe you could point me to these "force fields" you're talking about.
What are they, and who makes them?

Have you actually looked at how hard it is to get energy out of the
space environment? An RTG with about 30lbs of plutonium (and a few
hundred pounds of armor) can deliver hundreds of watts year in, year
out for decades. An RTG might not be worth the lawsuits in Earth orbit,
but in the outer solar system, it's a helluva lot better than an equal
mass of solar panels.

At this point it becomes clear that ramiga is an intentional troll, possibly
Elfnutz or Guth yanking your chains. Ignore it and it will go away.
