I'm not sure how to start this article but I have had a bit of a fixation on the subject of ternary computers in the last couple of months. I started to discover through my research that there are currently several patents pertaining to both the engineering aspect as well as ternary programming. One notable name on the list of active patents is Samsung the classification on the patent registry is G06F7/49.
Now historically speaking the most recent successful attempt at a trinary computer was all the way back in the 80s. Known as the Setun 70 it was the last computer based on the ternary programming system to be developed. Culminating in a short lived 32 version of the setun 70 before the project was abandoned. Due to political sanctions at the time of development. The production of models from this line is limited all totaling just over 50 units total.
Essentially the programming boils down to instead of the two valued system of 0,1 (bits). The ternary system functions on a three valued system consisting of 0,1 and -1(trits). This is an improvement on the perfect solution method of binary. This means that the trenary systems have the potential for parallel processing in multiple values. Because of the way ternary lends itself to parallel processing it may be the solution for the efficiency problems that plague modern computers.
The best example of the issues with efficiency would be in my opinion octa core. It realistically should trump a quad core but in my opinion it's much slower and apt to crash compared with a dual quad core. You can only go so fast in a straight line.
