Comment Typical.. (Score 4, Insightful) 530

So in order to not offend ANYONE, NO ONE is allowed to say ANYTHING.
This goes right along with sports where there is no winner\ everyone gets a trophy to PC playgrounds with no jungle gyms.
I weep at what has happened to my country in the past 30 years. I think it's time to start again from scratch.

Comment This is now antique technology (Score 2) 148

I was under the impression that the new Vasimir or Ion drives were WAY more efficient than this old tech. The only limiting factor is the size we currently them at.
Imagine an ion drive with 8 or ten modules, all powered by a fission reactor, it would start slow, but by the time it got halfway through the solar system would be cooking along at good clip. How fast is the potential ? No one seems to know, but a constant acceleration sustained for years would get you to a nice portion of C.

*sigh.. from TFA

PRISM is a so-called “fast reactor.” It uses liquid sodium, rather than water, to cool the reactor. The sodium allows the neutrons to maintain higher energies and to cause fission in elements such as plutonium more efficiently than water-cooled reactors.

Submission + - Waste heat to Electricity Breakthrough (sciencedaily.com)

drewsup writes: Researchers at Northwestern University have placed nanocrystals of rock salt into lead telluride, creating a material that can harness electricity from heat-generating items such as vehicle exhaust systems, industrial processes and equipment and sun light more efficiently than scientists have seen in the past
"It has been known for 100 years that semiconductors have this property that can harness electricity," said Mercouri Kanatzidis, the Charles E. and Emma H. Morrison Professor of Chemistry in The Weinberg College of Arts and Sciences. "To make this an efficient process, all you need is the right material, and we have found a recipe or system to make this material."
