Other Employment
Before becoming an Engineer, Ted held positions at California State University - Sacramento as a graduate research assistant. In addition to assisting instructors with class instruction and grading class papers, Ted conducted research with solar collectors, including the development of a concrete flat plate and glass collector with forced circulation and a high efficiency naturally circulating fin & tube type solar collector that powered a Serval refrigeration unit. When the solar collector and refrigeration unit was placed in the sun, the refrigeration unit had measured temperatures of 5 °F with outside temperatures of 90 °F. Ted's MSME thesis tied in with this project. The thesis, titled Cost Optimization of Fin & Tube Type Solar Collector was essentially a computer program that optimized the detailed design of a fin and tube solar collector by factoring in raw material costs to produce the least expensive solar collector for the BTU load required.
Prior to working as a graduate research assistant at CSUS, Ted paid his way through college by working as an ambulance driver and medical attendant. Ted also worked as a waiter, cashier and short order cook at the university cafeteria during the school year and as a Merchant Seaman during the summer, taking voyages between Panama and the West Coast of the USA as well as to Pacific ports in Hawaii, Okinawa, the Philippines and Vietnam. Before going to college, Ted worked as an Orchid grower, gardener and had a thriving business as a fisherman in Panama, supplying fresh fish to Panama Canal employees.

(hobbies & other things about me)

The hobby that I enjoy the most is the development of high technology boomerangs. I am well known for the development of the Maximum Time Aloft boomerang that currently holds all flight endurance records, including a throw and catch of more than 17 minutes. I have also developed long distance boomerangs, high speed boomerangs and many other flying toys. I have turned this hobby into a money making internet marketing business ( go to: ).

I have written and/or edited several publications about the science and sport of boomerang throwing. This includes the newsletters: "Many Happy Returns" (1988-2002 ); "Boomerang Journal" (1990-1992); and "Boomerang News" (1994 -1998). I have done technical presentations about boomerangs for the ASME and at many schools including the University of Michigan and Notre Dame University. I have also authored numerous articles about flying toys for Time/Life, Encyclopedia Britannica, etc. I have been featured in Mechanical Engineering and NASA Spinoff magazines for my development of high technology boomerangs. NASA is currently exhibiting a display of my Maximum Time Aloft (MTA) boomerang at the NASA Stenis Space Center, located near New Orleans.

I also enjoy throwing flying rings to my canine friends, throwing darts with the atlatl, playing chess, working on Macintosh and Windows computer systems. I also enjoy making money in the stock market using special algorithms that really work in any market conditions. Other hobbies that I have enjoyed include: breeding tropical fish, sailing, surfing, fishing and skin diving.
