Detecting systems with life

What are the other ways of containing a fusion reaction that might allow fusion to power a spaceship other than a tokamak type of arrangement.

There is more than one way of sustaining fusion in a reactor, other than magnets with superconducting coils.

A trip to the Alpha Centauri system in a craft going 30 light speed, for the experts outthere, how long would such a craft take to reach the Alpha Centauri system? do the math, a mere 4.5 light years away. I m refering to the binary system of Alpha Centauri, A and B. Even Gliese d, do the math.

oops sorry, i meant at 30% light speed.

thank you for the good information.

I haven't done the math but I do know at that rate by the time you got back to earth everyone you knew would be dead.

Not allowing for acceleration it would by my calculation take 285 yrs one way.

I think now I did some bad math and the time one way at 30% of lightspeed not allowing for acceleration or decelleration would be 15 years for the crew.

Interesting, 15 years for astronauts to reach the Alpha Centauri system in a craft at 30 percent light speed. So to Gliese d, looking at 40 to 50 year space mission in such a craft. I could see a craft powered by nuclear pulse fusion doing such missions. That is something that NASA can focus on, nuclear pulse fusion research.

Question? can the Atacama Large Millimeter/submillimeter Array be used for the detection of radio signals that might be artificialin nature from the cosmos? Basically, can Atacama Large Millimeter/submillimeter Array be used like Arecibo?

All I know is that a key person from the Allen Telescope Array has gone to Atacama. Maybe she can do something.

Allen Array will up and running again

Yes, the inertial confinement approach tried at Livermore National Laboratory, which makes H-bombs. But it uses high powered lasers and is not working yet. It is more an attempt to produce micro H-bomb explosions than producing power.

I don't think Livermore is looking into cold fusion.On June 24 there was an article on the NYTimes titled "Fusion experiment faces new hurdles".Its main point is that tritium used in the experiments can pollute the environment and cause lung cancer if inhaled. This was also the worry of the Nuclear Regulatory Commission about a sizable number of fission reactors in the USA. Tritium cannot be used as an explosive material but if you inhale it you are dead.

Tritium is what makes your watch glow at night. It is also used in some medical applications. I think that we used to burn it in our power plant at the university where I worked by putting it into the #6 fuel oil tanks that fired the power plant at the time.

Radon gas can also cause lung cancer--it was fairly common in basements in New Jerseysince much of the state sits over the Redding Tongue of uranium rich rock.
