Ion Propulsion
Check out this spacecraft
http://www.nasa.gov/mission_pages/dawn/news/index.html Apparently the ion engine can take the spacecraft up to 200,000 mph. Imagine going to the moon and back in just three days! We probably won't get to ride in an ion propelled spacecraft anytime soon but who knows, maybe our grandchildren or great grandchildren? How I would love to be there when that day comes.

Wouldn't an ion engine require particles to charge? Not sure what kind of particles they would be trying to capture and charge in space.

Rather I should specify - in a vacuum. Certainly there are particles in space but capturing them would be difficult and that seems to be the challenge at the moment, as many are super high velocity and carry a ton of energy, and somewhat sparse (depending on type) from what I understand.
