  As an ES builder, I usually just lurk on this list, but I couldn't help
  adding my 2 cents worth on the subject of pitot tubes.  Attached is an
  article by Eric M. Jones of the Periheliondesign.com web site.  He
  designed a pitot tube that uses Positive Temperature Coefficient (PTC)
  thermistors to automatically maintain a pre-determined temperature.
  (See attached copy)  The PTC thermistors are self-regulating, meaning
  that you turn it on and leave it on.  While I'm just a neophyte
  electronic tinkerer, I couln't help but think that maybe this technology
  could be applied to our Lancairs.
