I have been talking to NEW sparkies here over the years, and they ALL said there was no shock hazard at all with respect to neutral and earth. This worries me at a fundamental AC power distribution level.  They are obviously thinking that AC is DC cos they have some of the same colours. RED is phase in AC or positive in DC. BLACK is neutral in AC or negative in DC. Therefore, black is completely safe to touch(it isn't). See what I mean? (rhetorical)I have to admit that BOTH of those NEW sparkies gave me a deadpan stare and a blink without saying anything, when I simply stated that if YOU were touching the neutral, and then BREAK that neutral circuit(usually via the neutral loop on the back of most switches with both hands) by pulling the neutral loop apart while loaded....you WILL feel it.... To be fair to both of them, they both admitted that they had never thought of that, and that THIS WAS NEVER MENTIONED during their training. Perhaps it was just the training that THEY attended. I like to think so.... Smoke makes things work. When the smoke gets out, it stops! |

It seems that most sparkies get through training and that's the end of it...it's just a way to earn a wage. I was at an electrical distributorship and the owner of a local electrical contracting company came in asked for "some 100 amp wire"...  |

I am lost .... what is the connection with artificial intelligence... Guess that's purely artificial... PicomiteVGA PETSCII ROBOTS |

Sorry, Volhout.  The topic of this thread has deviated a bit. I'll try to get back on track with the A.I again now.  Smoke makes things work. When the smoke gets out, it stops! |

Does "Artificial" Intelligence mean that it's not REAL intelligence after all? |

To get back on track, I'll ask the question - The topic of the thread is the 'dangers of'... but what are peoples thoughts on AI? Excluding the movies, AI is coming in more and more and I'm guessing we're stuck with it now. I for one am not really too confident with driverless cars, but love the technology behind it (hey, do we really need NO driver in a car?). To me, it's pointless and probably bad. Then again, there's drone trials in Africa (errrr.. I think it's there, but could be wrong) delivering medical supplies with no human input aside from the initial delivery instructions. Probably good and I'm all for it. ... Then again, do I really need my pizza delivered by a drone? The fascinating one for me that is really scary when you think about it is this type of technology Atlas Robot by Boston Dynamics amongst others that they do... hmmm... serious techno, but where's it going? (Go watch Terminator again!) John |

Hopefully it will drown in its own Sargasso Sea of dud information. Ask Siri to call Alexa. In fact ask Siri "What did the fox say ?" |

Just more fodder for the scare mongers. When I was a kid, it was the Soviets, then we get fake terrorism and man-made climate change....there always has to be a boogeyman to keep us afraid. |

Driverless cars: Seat belts have been mandatory for many years but back in 2005, I'm absolutely certain that my car's radar saved my life. Why isn't this mandatory? Could it be that they are more concerned with saving a life than preventing the collision that would negatively impact car sales? |

I expect to need it, and the need could happen quite abruptly. In many places, uber or lyft would do as well, and less expensively, but I expect they won't reach the remote-ish village I live in for half the year for quite a while. And I'd be quite happy to let an automaton handle the 3,300km drive I do twice a year. (Flying would work quite well if we could travel with less gear.) This isn't going to be governed by +my+ need, but by the need of the pizza place to deliver more cheaply than the next guy. And so for all non-private transportation unless there are job-saving regulations (known in the past for the railroads as "featherbedding"). Lots of scary stuff when you consider that an AI smarter and more capable than we are could well decide that it, and most other species (excepting those we favor, like cows, chickens, pigs, corn, wheat, etc.), would be better off without us (especially if we are in control of its OFF switch).

The slowness has been fixed without AI by laying fibre optics to get access to trades a few nanoseconds prior. Taxation as a means of achieving prosperity is like a man standing inside a bucket trying to lift himself up. Winston Churchill |

Regarding drones: With the escalating usage of drones I predict the introduction of mandatory use of on-board anti-collison technology. I for one don't fancy being dumped on by 2 pranging drones complete with payloads (but maybe I'll score a nice pizza  ).What a fertile environment for drone hacking & diversion of the payload to me  Looks like a whole new industry is about to be born... Just sayin' B |

What worries me is the increasing use of drive/fly by wire systems where the human driver/pilot has no direct physical control of a system that can lead to a very fatal crash. While such systems can and will be designed to have self checking and redundant systems, that cannot guarantee that someone has not deliberately hacked into the the system, and you would never know until its too late. And its not just the crazies. Governments are now doing this as a matter of policy, deliberately building back doors into things. Cheers, Tony. |

AI hmm. Doesn't worry me at all. Movies aside an insect demonstrates more intelligence than the best current tech. Not only can they wobble awkwardly through the snow and avoid obstacles. Their software allows simultaneous processing of energy procurement, threat detection and avoidance, environmental modification to improve survivability, and software and hardware replication. If theoretically a machine became self aware I wonder if it would then share the same limitations that some say so handicap humans. would crisp decision-making be slowed down by self-doubt, self-esteem, embarrassment, ego, etc. Self aware by definition involves more than recognizing you are an individual, all animals seen to perceive this and no one seems worried they will take over the world, but an awareness of how one is perceived by others. It is this aspect of self awareness that gives rise to cooperation and morality. Why do we keep thinking that true intelligence can be separated from , well... true intelligence? Because it is a machine which is intelligent why does it have to decide like a machine? Now there are undoubtedly better programmers out there than me, an maybe they can chime in, but I've played with fuzzy logic and pseudo learning algorithms enough to know that state table are state tables and data sets are data sets. You can program probability, statistical analysis, and heuristic branches and make some cool simulations of intelligence but we are talking about exhibited behavior which not only surprises but surpasses input. Who said that "to the uneducated anything is possible"? I have to smile thinking of an AI stressing about his book report presentation. A ramble to be sure.... |

The Tesla autodrive system has already been 'hacked' (well it was being fed incorrect info, rather than a software hack, but...) (apparently if you use a certain liquid/paint on the road, it fools the computer into following the 'fake line') |

F.W.I.W. AI-designed heat pumps consume less energy Sat, 06 Jul 2019 12:35:04 EDT Researchers have developed a method that uses artificial intelligence to design next-generation heat-pump compressors. Their method can cut the pumps' power requirement by around 25%. |

Cool, but I think they have some catching up to do. If the A.I. system is already programmed to accept that the first law of thermodynamics is true....it won't get as far as it could. I, for one believe it to be false and I can't accept that since Faraday came with electrolysis, back in the 1800s that we simply accept that splitting water requires more energy than hydrogen can provide. 1833, I believe....and that's it???? No...WAY! High voltages at certain frequencies and virtually no current (no power) can achieve the same thing. |

NICE FIND BRIAN!!!! This significant work was completed this year at the Ecole Polytechnique Fédérale de Lausanne by two PhD students, Violette Mounier and Cyril Picard. After several years of effort they were able to produce significant increases in efficiency by replacing piston compressors, which waste a lot of energy due to the friction generated by the pistons sliding up and down in the cylinders, with turbo compressors using gas lubrication in the rotating bearings. It's too bad that they didn't compare their turbo compressors to the orbiting scroll compressor produced by the Copeland subsidiary of Emerson Electric. This ingenious gadget reduces the sliding friction energy loss to a small fraction of that produced by piston compressors. It's been in production since about 1965 and it's used in virtually all U.S. manufactured heat pumps. https://www.youtube.com/watch?v=dsabYhhOko0 The ground source heat pump operating in my house since 2012 pumps about 64,000 BTU/hour (19050 watts/hour) of heat with an power consumption of about 5,500 watthours per hour. In other words it produces about 3.46 times as much heat as resistance heaters would produce. Part of this very high efficiency is due to the fact that I move the heat around by pumping water at low velocities through large diameter HDPE pipes which uses about 15% of the power needed to transport the heat by blowing air through ducts. Turbocompressors like the ones employed in this paper will produce some additional efficiency improvements but they will cost more than five times as much as the Copeland Scroll compressor to manufacture. Similar turbocompressors have been powering the climate control systems on most commercial aircraft since the 707 was introduced in 1958 and they are very expensive to manufacture. The big advantage of heat pumps comes from the fact that there is no attempt to convert either electrical energy or potential energy bound up in hydrocarbon compounds to heat, the gadget merely concentrates diffuse heat found in the outside air or the deep ground into more concentrated heat at a higher temperature and moves it into the building. All of the laws of thermodynamics are therefore bypassed. Paul in NY. |
