At 34 Paul Lutus wanted to get a way from it all, while taking it all with him.  He built a cabin in the wilderness with no running water, no telephone — just a cat for company.  A cat and a computer.  Lutus wanted to see if he could work as well in the woods as he did in the city.  He worked better.  The computer programmer was a consultant for NASA before he went into the wilderness.   He helped get the Viking Space probe to Mars.  In his tiny shack, miles from the nearest road, Lutus created a new lighting system that is now part of the space shuttle.
