They reported that the TRONgroup (whatever it is officially called) included several European vendors, and they went into some depth on a project to build a "smart house" with about 10,000 microprocessors (mostly 8-bit it seemed). In addition to the smart house, there was a smart office complex underway. The "big wins" from having fully enlightened and mutually comunicating applicances was that turning up the stereo would close the windows, turn up the air conditioning, get turned down by the phone, etc. In addition, turning on a light would result in more air conditioning. The guiding principal was supposed to make life better and easier; every design decision is supposed to be made from the user perspective ... While CNN is most certainly not the best sort of medium for a technical exposition, it seemed that the goals (or examples thereof) could possibly justify the expensive of the massive wiring harness (which they showed), the decreased reliabilty (I cannot see how connecting my toaster and microwave to my reading light can _increase_ reliability of the system) and general increase in complexity. In addition, the stated plan was to start with a sample house and office bldg; work up to a city (big brother watches each toliet flush, and reacts accordingly) then to a province (chiba ?) then to all Japan, then to all the world .... While this is probably a good warm up for building a large multi-generation spaceship, the vision of a vast number of Z80's communicating with some Fifth Generation Supercomputer with the big payoff being that my heating and airconditioning might be 5% more efficient (somehow having a few more thermostats didn't seem to occur to them) does not seem all that interesting. The TRON keyboard (very post dvorak), the communication protocols, and many of the other subprojects are probably quite interesting. But the fundamental mindset (presumning the CNN staff was doing due dilligence ... which is admittedly uncertain) seems wrong ... having appliances talk to each other, across the world does not automatically make sense. I am hoping that one of you NetLanders can enlighten me ... why are the TRONfolks working so hard ... what are the problems they are trying to solve. Until these are clearly articulated, arguments about how many wires are needed to build a robust applicance communications channel seem moot. Keith H. Bierman |*My thoughts are my own.
