This is the website for the company working on the plasma rocket, I thought it was pretty interesting:
Ad Astra Rocket Company

Also, there was a thing on PBS about it:
NOVA ScienceNOW

This plasma rocket sounds awesome, and kinda easy with today's technology... What exactly is holding this back? Could we not make it today?

Has solar sails for interplanetary travel, or laser photon sails for interstellar travel, been mentioned yet in this thread? They're some nice, clean and romantic forms of travel that's good for stories. Especially if you include something ridiculous like the tachyon stream that pushed that DS9 solar sail across interstellar space, if your story needs a FTL solution.

These streams could be set up like spacelanes, and you could use something less stupid than tachyons too. Maybe parts of space with suppressed vacuum energy, like a Krasinkov Tube.

The plasma rocket is under developement, actually.
On another forum, I read an article about the idea.
It's known as VASMIR.

I mentioned sails.
Trekbuff doesn't think it's workable.
One would have to do some reading on it to find out just what it can do.

I have heard the term VASMIR come to think of it. Neat.

Hey, some book I got from the seventies called "The Road to the Stars", thinks sails are the bees knees. It reckons that a conventional solar sail could be used for missions as far as Saturn. And this years Guinness Book of Records has a Japanese Solar Sail in it. Don't know where it went...

As for interstellar travel, my seventies book places a facility of some sort on Mercury that collects energy from the sun and occasionally fires beams towards a target star that ships can use for acceleration. Returning ships can use the beam for deceleration as well. It stands that an interstellar civilization might have this sort of set up for standard space lanes. One draw back mentioned in the book is economic and social changes back home may led to someone switching off the beam and leaving our crew LOST IN SPACE! And that would suck... But it might be a story in itself!

Here is a new one to generate discussion. We know that iron is the main element involved with the collapse of a sun into a blackhole. The reason is is due to the absorption of the energy of the other atoms present by the iron atoms. After all of the energy has been absorbed by the iron atoms the iron atoms then absorb their own energy that they are giving off until once super dense iron atom containing all of the suns energy is left. Once the iron atom has lost it's field integrity the energy is released into a super nova or a black hole.

The NIF is currently underway in trying to create the same process in a sun to generate a sustainable electrical power supply. The theoretical aspect of the idea is that if iron atoms are injected into the process at a controlled rate where they do not propogate uncontrolled like they due in the collapse of a sun it could be possible to generate the same energetic release that occurs in a sun but instead of the process ending in a super nova or blackhole the process could theoretically produce an unlimited amount of thrust based upon the amount of iron atoms injected into the process. It might even be theoretically possible to take the process to event horizon of being a blackhole with an extreme amount of thrust potential capable enough to propel a ship to near light speed.
