At some point in the device is a microcontroller pin where OK = H and infected = L (maybe open collector from multiple sensors who knows). The app on the phone merely reads binary 0 or 1 and then promptly, probably literally, phones home to report.

    One can easily imagine why given the ridiculously baroque and counter-intuitive system you've just described.

    Its perfectly reasonable from a green perspective. The fear is "angry employee" goes home in August on Friday and sets the thermo to 50 on the way out to F the company thats Fing him/her. Another way to think about it, is the victims are forced by programming to raise the thermo in the summer and lower it in the winter. For a certain mixture of greenie and control freak its pretty much a dream come true.

    A quite reasonable expectation with any thermostat is that when you set the temperature on it, that is the temperature the system will reach and maintain. A perfectly reasonable conclusion from that assumption is that the system will attempt to attain the initial temperature relatively quickly without "overshooting", and thus a larger delta will bring the temperature down quicker.

    99% of HVAC simply does not work that way. You don't need a PID controller with overshoot control because the systems are typically designed to be profoundly overdamped, generally by having huge thermal mass. There are numerous industrial process controls that require some control system theory... HVAC is not one of them. If your HVAC system is underdamped and requires advanced PLCs and PID controllers to prevent oscillation, you've paid your HVAC guy for waaaaaay too much capacity.

    If the interface to the air conditioner is "short circuit means on" and "open circuit means off", the delta inside the thermo can not possibly even theoretically matter as regards "bring the temperature down quicker"

    I've also seen thermostats that, while they don't directly control the system, do alter the way the system cycles. I believe it's some kind of 'intelligent' system that realizes if Department A wants 70F and Department B (next door, open air) wants 90F, it's a waste of energy doing them separately and just pushes out 80F.

    I worked at a facility where a thermostat set above seventy-something is in air conditioning mode and set below that is heating mode. And I worked with morons whom alternated it at extremes and then couldn't figure out why the HVAC didn't work. I get to work and its about 50 in the cubes ... cow orker says "I'm freezing so I set it to 85" ... "Well, don't you think 85 is kind of high for the airconditioner?" I turn it down to 70 and we warm right up. Same deal in the summer. Its 90 in the cubes because some clown set it to 60 placing us in heating mode, and god knows its well above 60 so nothing happens. I crank it up to 75 and we're soon chilling. And the amazing part is these people NEVER LEARNED. Ever. I would imagine they're still all screwed up.

    I'm amazed how many people think HVAC is strictly proportional and the thermostat tells the machinery how hard to work. That technology exists but is rare and expensive and you almost certainly don't have it.

    Heh... so I'm either depending on "magic", which won't work because magic doesn't exist,

    Well, it inherently limits the usefulness of the discussion. My imagination is different than your imagination doesn't really accomplish anything.

    I'm using a method that generates toxic waste, and therefore it won't work because I'll have disposal problems.

    Ah the key to our misunderstanding. Its the inputs that are toxic and they will be output, somewhere. You can't accept tons of lead and heavy metals and strange organic compounds at the intake, and not expect some expense to prove that the plastic baby's nuks at the output are not full of lead. That lead has to go somewhere, and costs of material handling and storage are not eliminated by working/wishing on the disassembly and refining process. In fact, industrial experience shows that the most expensive part of being in the lead chemistry business isn't raw materials or process energy but in safety systems, compliance, cleanup, documentation, lawsuits by anyone tangentially related whom ever gets cancer, etc. You just don't want to get into the business of handling lead if you can possibly avoid it.

    You know the very old claim that supercomputers turn a processing problem into an I/O problem? A magic solution to recycling laptops is merely going to create an "insurmountable" new materials handling and environmental cleanup problem...

    You can also end up with the anti-nuclear fuel reprocessing rules... The danger being a cheap and popular technology could result in fools dumping excess purified organometallics into the river. You or I would never do it, but some fool would. Thus we are not allowed to reprocess nuclear reactor fuel in the USA, and possibly laptop recyclers would be banned for similar reasons.

    Just because you can't imagine how to do something doesn't mean it won't work.

    I would disagree in that is usually the case. Many people agree with me on faith healing, astrology, and almost everyone agrees that 99% of human religions must be wrong, etc. I don't see how to make a machine that violates (insert any law of thermodynamics or physics here) and oddly enough that means it won't work.

    Specifically I was thinking of maybe using the nanoparticle sorting technologies that have been developed in chip size for materials analysis, or maybe a centrifuge based sorting process with the waste liquified. Maybe even building macro scale robotic sorting devices to separate waste at multiple scales.

    OK interesting but that refining process is only a tiny slice of the overall system of a company that ate old laptops and crapped raw materials and cash. It would also be quite handy for primary inputs not just recycling. Imagine how handy it would be to remove the sulfur or mercury or uranium in coal going to a power plant...

    Also, there's nothing wrong with using a lot of energy, just like there's nothing inherently wrong with spending a lot of money, if the result is a net gain. If we remove more garbage (solid, liquid, and gas) from the world than we add, we're moving in the right direction.

    Be careful to keep complete system costs in mind. Which is far from me claiming its impossible. It is, however, possible to end up recycling 10 grams of mercury from alkaline batteries, by burning ten tons of coal at the power plant, thus releasing 100 grams of mercury into the air, net loss by recycling of 90 grams. Agree with you that one anecdote does not disprove an entire generalized industry, but it most definitely proves there exists at least one minefield with at least one mine in it, and probably many more. Also it can be inherently wrong if there is something "better" to be done with the energy or cash, perhaps R+D to economically eliminate the entire polluting process?

    Yes, it'll take energy. Just about everything does :)

    Unless you accomplish a miracle of 100% recycling and sell all the parts at a profit, you'll have some manner of concentrated semi-toxic waste to dispose of, perhaps at greater expense than just dumping it all, in bulk, into the sun or a volcano or something. The EPA and OSHA costs of a big pile of lead and lead contaminated "stuff" cannot just be waved away, nor the energy costs of continuous Q+A to make sure you're recycled plastic for kids toys isn't full of lead.
