There is a guy in Maui who has an art studio called "Elan Vital."  It's mostly those big pictures of waves and ocean that you see so often in Hawaii.  I haven't heard of Elan Vital going after him for copyright or trademark violation.

There was an Elan Vital company in California for awhile, but I think it never really got off the ground and is dissolved.

Love the "gas analysis" term.
