ESA reports tests on DS4G produced an ion exhaust plume that travelled at 210,000 metres per second. >>

If they can get an exhaust plume that travelled at 186,000 miles per second, THEN we'll be getting somewhere!

[Sutherland says laboratory tests show the DS4G it is four times more fuel efficient than the best ion engines available and 10 times more fuel efficient than used to propel ESA's SMART-1 Moon mission.]


As soon as they get that FluxCapacitor fluxing again then we'll really be in business.

Unfortunately, that would require an infinite amount of energy. Give me a Heim drive instead!!

From the Science Fiction of my youth.

Looks like the legendary flux capacitor...

Not at all. My flashlight has a photonic exhaust plume that does exactly that, and it runs off of a couple of D batteries. Unfortunately it doesn't seem to be moving very quickly....

No problem. Where'd I put that flashlight?

Sutherland says the ion engine needs megawatts of power to generate the necessary voltage across the electrodes and to generate the ion-providing plasma.

Marty: This is uh, this is heavy duty, Doc, this is great. Uh, does it run on regular unleaded gasoline?

Doc: Unfortunately, no! It requires something with a little more kick -- plutonium.

Marty: Uh? plutonium?? Wait a minute, are you telling me that this sucker is nuclear?!

Doc: Hey, hey, keep rolling, keep rolling there. No, no, no! This sucker's electrical. But I need a nuclear reaction to generate the 1.21 gigawatts of electricity that I need.

Marty: Doc - you don't just walk into a store and ask for plutonium. Did you rip that off?

Doc: Of course! From a group of Libyan Nationalists. They wanted me to build them a bomb. So I took their plutonium and in turn gave them a shiny bomb case full of used pinball machine parts.

My '91 Toyota Previa gets 22 mpg!

I am really bad at math, but if I am correct now, that is 471,000 mph.
Could someone a little more talented at arithmetic please verify?

Er...no ...I've only hit 87mph in the Previa (downhill).

469756.6213 MPH- You were pretty close, but it's way below light speed. 210,000 meters per second equates to 130.4879504 miles per second.

I canna' only give ya' impulse, Cap'n.

To four significant figures: 1,217,000 mph

Sorry for the wrong figures in the post. (It does make a difference what you put in the numerator and denomerator!) You are correct. 469,800 mph to 4 significant figures.

A lot of hype on this engine.

Could also be the Oscillation Overthruster.

Useless Factoid: The flux capacitor from the BTTF series was the oscillation overthruster from Buckaroo Banzai - Beyond the 8th Dimension. It has also appeared on various Star Trek episodes and Babylon 5 to name a few.
