"This may sound “fanciful” but new research is starting 
to emerge revealing that a miniature magnetsphere can 
be used to protect humans
and spacecraft."



He could at least learn how to spel....magnetsphere.

fan·ci·ful
'fans?f?l/
adjective
adjective: fanciful

    (of a person or their thoughts and ideas) overimaginative and unrealistic.



At least he's honest about his thinking...unrealstic.



Put him in charge of ...NASA.
