    Shields up!

    http://news.bbc.co.uk/1/hi/sci/tech/6567709.stm

    Another 'Star Trek' piece of technology moving out of the realms of scifi
    Look again at that dot. That's here. That's home. That's us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilization, every king and peasant, every young couple in love, every mother and father, hopeful child, inventor and explorer, every teacher of morals, every corrupt politician, every "superstar," every "supreme leader," every saint and sinner in the history of our species lived there--on a mote of dust suspended in a sunbeam.

    This would be very helpful if not essential technology for "real" human space travel

    Why not essential? At the moment they have to put in a shield in some shape or form?

    Well the essential value in this I would think should depend on whats more cost effective and energy effective.....


    Generating a "force field" like this may cost a high amount of energy. Some sort of physical shielding would not cost energy to work but would require more energy to put it into orbit because it would add a lot of weight to the vessel.....


    So yeah shielding of some sort is definitely essential.....I was just saying "very helpful if not essential technology " because it seems likely that they would not use just "force field" technology but some combination that creates a situation where it is as energy effective and cost effective as possible....


    I hope you get what Im saying....Im kindof preoccupied and cant spend any extended time thinking about my post wording...

    I suppose the +ve is it can be varied according to requirement. The -ve is if there is a failure/problem (sounds somewhat more complicated than a lump of metal), the astronauts fry!
