Well, doh! This is the height of intellect for you, I assume?

Nobody said anything about "stored fuel cells". You don't read very

Obviously you do not, since your 'facts' are not.

And Naysayer Navia will be bleating about how it simply cannot be done

Seems to foolishly assume that nothing will be done to deal with or
manage the 'risks'.

Grossly overestimates radiation exposure and then assumes nothing will
be done to deal with or manage it. Even then it only gets to 'cancers
late in life'.

:National Research Council report:
:Safe on Mars
:http://www.astrobio.net/news/modules.php?op=modload&name=News&file=article&sid=1432&mode=thread&order=0&thold=0

"Unless provisions can be made to counter the microgravity environment
(by means of exercise protocols or by inducing artificial gravity) and
harsh radiation conditions in space, the potential negative effects on
health of the longer transit time (short-stay mission) may be
prohibitive."

So take provisions.

"Hopefully, eradication or treatment of these diseases will be
possible in the near future. We need more research and support to
solve this puzzle, but we feel that we are close," adds Ciftcioglu.
