Vasimir-Motore al plasma

VISITA IL BLOG http://mida999.wordpress.com/
La Nasa ha firmato un accordo per sviluppare una nuova tecnologia propulsiva definita "al plasma" insieme alla società fondata dal fisico ed ex-astronauta, Franklin Chang Diaz, originario del Costa Rica.Con motori al plasma si indicano dei propulsori elettrici per uso spaziale che sfruttano la fuoriuscita di masse gassose ionizzate (il plasma), accelerate da campi elettromagnetici, nel processo di generazione della spinta.
Anche se molto meno potenti rispetto ai motori a razzo tradizionali, i propulsori al plasma sono in grado di operare con maggiore efficienza e per lunghi periodi di tempo. Essi sono più adeguati per un impiego su percorsi spaziali di considerevole durata e distanza.. Chiamato Variable Specific Impulse Magnetoplasma Rocket (VASIMR) sarà realizzato dall'azienda di Chang Diaz, la 'Ad Astra Rocket Company'. Il motore al plasma, secondo la Nasa, sarà provato a partire dal 2012 sulla Stazione spaziale internazionale (Iss) in orbita intorno alla Terra.

@Darklotus390 As if the republicans don't spend billions on endless wars.

Both sides do dumb shit...you seem like an idiot right winger

@MrTiti this statement means nothing and is full of run on sentences. stop drinking the bong water.

[MrTiti]

@circusboy90210 i have multiply explained it, my last sentence even asks you to do think about it. i once again see that you have not understood what i tried to explain. and no, not arrogant, it was a classification of your statements about social ranges, sociality, e.g. (you could find out about in in a library etc.).But never mind, i didnt mean poor in a material way. your answers still clearly show you have understood 10% of my words.you "could try to -properly- understand", concentrate, etc

@MrTiti the idea of life is to simplify as much as possible without overdoing such. I"m not from the weak class nor am I poor in any way, nor will I ever be. to think that I should aspire to be you is kindof arrogant on your part . how many phd's do you hold??

[MrTiti]

@circusboy90210 I must disappoint you, without offence, that your thoughts are very simplistic and miss out about 3 of 4 basic coherencies i mentioned abovewhich are still partial. Surely youre right that too much "propping up the weak" would damage the society. But what you stated is the thoughts of the lower "class" (yes also, no ESPECIALLY! the weak) in the advanced European countries. With that attitude you even subordinate your own life.Yet: Your thoughts COULD develop to my elucidations.

[circusboy90210]

@MrTiti yes the strong can protect the weak, and the weak need to stand up on their own instead of depending on and draining the strong. life is about survival of the fittest propping up the weak does nothing to strengthen society but further weaken it.

@gooyzit ion engines have incredibly small power output, they are not feasible atm

[MrTiti]

@circusboy90210 Fairness is a basic requirement for satisfaction. Maybe you mix up fairness with equality, which you speak of 9 words later. And: We aren't born equally. We have different intellect, we have different strengths, we have different behaviour and characters (which make us humans strong). The strong can protect the weak. (in another situation the weak can be the strong one). The traits of ignorant people: you said it: we adapt where we grow up and learn there(!) "how life works".

[circusboy90210]

@MrTiti why would you ever want anything to be fair in a democratic society. we are all created equal but quickly become not so. nor would it be a great thing from any viewpoint(engineering socioeconomic or otherwise). yes poor people can create tings on occasion but usually are too hung up with petty concerns to do anything in life. ignorant people do not get money very easily nor do they hang on to it very well.

@circusboy90210 Sorry, my dad is an engineer, i studied engineering and was asked by a Professor of the M I T, thats right, to wrk for him in my first Semester. I totally disagree. I became a teacher and the layers of society, especially the way up and down and possibilities of the lower percent are completely different than what you claim. i myself prefer performance, but especially the US of A have one of the most unfair social system. and most ignorant people on the top side.
