Yes, but instead of moving lots of mass slowly, plasma rockets move very little mass very,very fast. The effect being that you can accelerate to the half way point, pull a 180, and decel the rest of the way, and set yourself cleanly into orbit, at a small fraction of the fuel mass than it takes to get the shuttle into orbit.

That's all without taking into account that reducing the mass per newton means you have to send less mass to begin with, which makes the fuel use even more efficient.

Forget cold fusion, hot fusion will take us to the stars.

Indeed, but only to a point...well 2 points that is. The mass and density of the atmosphere and cosmic body in relation to your speed, and the G forces it creates are still a problem for humans...for machines not as much. In other words, you can't hope to be going near light speed and use, say, mars to slow you down , and even if you could, the G force from near light speed in a straight line to an angular velocity would be deadly (as depicted in the 9g turn on the Apollo 13 movie.)

Sorry, I should've been more clear. I accidentally commented twice. Couldn't find a way to delete it, so just edited it. Next time, I shall say: [edit] doublepost.

Comment hidden because you are ignoring dag. (show it anyway)

Aerobraking works.>> ^GeeSussFreeK:
Wes is actually points out something implicitly hard with space travel. You can only speed up to certain levels of speed because you lack the ability to burn off speed in a way that doesn't kill the person inside. It takes 354 days to accelerate to light speed under 1g (you can't get that fast mind you, but this is just to show the problem).

surly the faster you go the more you have to decelerate so say u got to mars in 30 days as aposed to 1 year you would have to spend ages going around its gravity feailds before u lost enough speed to safely enter the atmosphere. ethor that or you are going to have to waste a tun of fuel to brake.


Yeah, too bad we don't have thousands of people and billions of dollars to figure out problems like that.

Might as well give up everyone! The naked guy with head-phones says its a dumb idea!

NEATO! Hey, I dug up some more technical information on the plasma rocket when I saw this video

He went back for the tube. Why'd he go back for the tube? He was totally in the clear...


He was screwed from the second he did the double pace.

Yeah, I didn't like this voice either. Must be something wrong with his plasma coil.

"A Parallel Image is technologically completely transparent, conveying to the viewer a correspondence between real world and transmission that can be sensually experienced."

The thing is cool, but give me a fucking break. 1080P plasma is friggin sensually experienced. a ViewMaster is sensually experienced.

"As above, so below".
As many of you already know, if you look at the patterns found in nature, they are repetitive, in both grand scale and small. These birds form the same chaotic patterns that gaseous clouds of dust form out in space, albeit the birds are much more sped up. Or maybe they exhibit the same behavior as super-heated plasma.

Another example, I was eating a picnic once and had a sandwich with poppy seeds all over the bun. By the time I had finished, there was a large number of poppy seeds that had fallen off onto my white paper plate. I noticed that they had fallen into such a pattern, black seeds on white paper plate, that if you had inverted the colors, you would have had the random cascades and invariable strings that stars form in the night sky. With each shake of the plate, I was able to recreate random, chaotic strings of seeds, which continued to look like an inverted picture of the heavens.

This is also why I believe the universe will not end with a "Big Crunch", and also will not conceivably keep expanding forever. Just like any explosion found in nature, it is always the "fireball" expanding into space that is already there. I believe that on a very simple scale, our universe is just an explosion, rapidly expanding and thinning out into an already existing medium (dark matter?). We won't collapse, and we won't keep expanding. We'll just eventually thin out and cool down enough that the universe will filter out into the background. One could ponder the question, "What is beyond the edge of the universe?" but it could very well be a fruitless question. There has always been something on the other side of the hill, ocean, sky, solar system. Who says that has to stop when we reach the edge of our universe? What is beyond the medium we are expanding into?

Anyway, cool birds.

Trully stunning indeed. I assume this is a one off video, and not part of a DVD or something. Wish it was as I want more and want to see this in full 1080p on my Panasonic Plasma.

Thanks for sharing.

Edit - Oh wait it is from a DVD. Gonna try and find a copy somewhere.

Good news everybody:
"In September 2009, the US Department of Defense announced further funding of $7,855,504 for Energy Matter Conversion Corp for research, analysis, development, and testing in support of the Plan Plasma Fusion (Polywell) Project. Efforts under this Recovery Act award will validate the basic physics of the Plasma Fusion (Polywell) concept, as well as provide the Navy with data for potential applications of polywell fusion. The project is expected to be completed by April 2011."
