    Heh. Exactly.

    DRM is an exercise in futility. Protecting streaming media is exactly as important as protecting radio broadcasts, i.e. not at all. Completely unimportant. It's a waste of time and money that could be better spent making higher quality programming. It does nothing to prevent people who are determined to capture the audio program, and no matter what they change in the DRM tech, it cannot prevent it).

    Unfortunately, it does do lots of harm in other areas; it causes unavoidable compatibility problems, prevents average people from format-shifting to devices like iPods for listening at their convenience, prevents average people from time-shifting pseudo-broadcast content to a more convenient time, and in general, massively erodes at every aspect of legitimate fair use without actually providing any provable benefits in preventing "piracy".

    IMHO, the Audio Home Recording Act should be expanded to cover digital broadcasts/streaming media in any sane universe. The term "piracy" should not even apply to non-purchased media that is freely provided for download or streaming, so long as that media is only copied for personal (defined as non-commercial) use. We need to nip this stupidity in the bud.

In a 15-passenger fan, that's about 25 feet of water hose each way by itself---about 20 feet for the length plus a little extra to reach the heater core, which I assume is in the ceiling.

    By 70,000 miles, my Ford Windstar had already had to have the intake torn down and cleaned due to a flawed valve cover design sucking oil through the EGR hose (emissions control crap) clogging the vacuum lines, causing the computer to adjust the fuel mixture incorrectly and show a Check Engine light. The overdrive off light started blinking periodically due to a solenoid problem in the automatic transmission. It also had a faulty switch on the air conditioner that caused the rear air to randomly turn on and off. Several replaced bulbs. Recall for something wrong with the fan controller for the rear heat or something, recall for overheating wiper motor, recall for two or three other things. Problem with the suspension system causes a rubber boot to rub against something under there and make noise. Oh, and then there was the fuel line that blew off the back of the fuel filter while I was driving down the road. I'm sure if I thought about it long enough, I could list plenty of other problems.

    Okay, so maybe that qualifies it as not a "decently made car", but nearly 100% of the problems I've had with my vehicle stem from actual problems with the drive train, and the bulk of those stem from emissions control hardware.

    Computers and sensors have actually simplified the engine control system considerably.

    A modern car is more efficient and runs smoother. It is NOT simpler in its construction. A carburetor is pretty mind-bogglingly simple compared with computer-controlled fuel injection. It either works or it doesn't, and when it doesn't, you're not sitting there trying to figure out which damned vacuum line is clogged causing the engine to run lean. Likewise, manual transmissions are so much simpler than automatic transmissions that any suggestion to the contrary qualifies as delusional thinking. Ask anyone with a Ford Windstar what they think of transmission reliability. Ask anybody who has gone through three computers in their Chevy pickup what they think. There are simply way more things that can and do go wrong with a modern engine without abusing it.

    In the old days, if something went wrong with an engine, it ran rough or misfired once in a while. If a mechanical distributor went bad, odds were you lost a cylinder once in a while. Nowadays, when the computer or the electronic distributor goes haywire, you don't get spark on any cylinder. Instead of a simple carburetor in which your foot controls the mix of air and fuel, you have this computer doing the controlling, and if one of those vacuum lines gets a bit clogged, You die every time you take the foot off the gas. And so on.

    No, those sensors and fancy electronics do not make cars simpler. They make repair somewhat simpler so that people can diagnose many problems without actually having to learn anything about how the vehicles work. That's not the same thing as making the vehicle actually simpler. Further, making diagnosis easier actually means that when something goes wrong that the computer can't explain, you have people with no real car repair knowledge whatsoever standing around with dumb looks on their faces not being able to figure out how to find a low temperature leak in a metal water line just under part of the intake manifold shroud. Five days.

    I doubt the motor controllers will last much longer than 10 years, on average. They all use large electrolytic capacitors, which don't last that long. In general, complex high-power electronics is not too reliable. If you do make that reliable, you still have the issue of batteries, which will certainly last less than 10 years in any EV. In all likelihood, an EV will be much more expensive to own than a gas-powered car.

    A motor controller does not necessarily need any electrolytic capacitors. There are designs for PWM-based controllers that do not use any capacitors. Here's one.

    Fast-charging battery tech is certainly a possibility, but the faster the charging, the shorter the life of the battery tends to be. By contrast, supercapacitors can also charge up in seconds but have no such limitations about lifespan. And unlike those batteries you're talking about, they can scale up to vehicle sizes today. For all practical purposes, charge speed with supercaps is more likely to be limited by the amount of power the grid can provide. :-)

    Either way, though, the argument about recharge times made sense ten years ago when lead-acid batteries were the norm, but doesn't make sense in light of modern technological advances.

    Hydrogen electrolysis of water will almost certainly always be less energy efficient than using capacitors for storage. The only reason anybody cares about Hydrogen is that you can get a little bit better energy density right now, but supercapacitors are quickly catching up. Hydrogen is not the answer. It is the question. "No" is the answer. The primary goal of Hydrogen-based power is to keep people dependent on filling stations, not fixing our energy problems or saving consumers money.

    Apart from people taking long trips, it offers no advantages over a pure electric system and lots of significant disadvantages, both in terms of producing emissions (H2O is a greenhouse gas, sorry to say) and in terms of inefficiency. Add to that the extra risk of driving around on top of what amounts to a giant bomb (gaseous hydrogen + spark = barbecued passengers), and it just screams "completely wrong answer". Oh, and it is much more complex. The car companies love this idea because that hydrogen power plant is one more part that will wear out, leak, or otherwise require maintenance ($$$) and is likely to cost almost as much as a new car does when it comes time to get it replaced. More money in their pockets, less money in the pockets of consumers.

    Electric cars are a huge win there, too. The complex emissions control nightmare that U.S. law requires makes the drive train incredibly failure-prone. Automatic transmissions make them doubly so. Add in the complexity of computer-controlled everything and you have a device that is orders of magnitude more complex than cars were fifty years ago. And people wonder why cars seem to break down more often. It is like using a shiny new computer with monitor and printer where a printer-calculator would do the job. The simpler the device, the less failure-prone it will be.

    With electric cars, you have basically four parts: a battery, a bunch of heavy gauge wires, a charge controller, and an electric motor. All of those are generally simple devices except the charge controller. Okay, so there are a few other things like an electrically-powered pump for your power steering and a modified A/C system, but in terms of the drive train itself, you get rid of a lot of crap. You get rid of the internal combustion engine, the computer that controls it, the transmission, potentially the radiator and hundreds of feet of water hoses (that leak), the oil pan (that leaks), the oil hoses (that leak), the fuel pump, most of the vacuum system, the catalytic converter, and the entire exhaust system, all of which are fairly frequent points of failure. Add to that dozens of sensors that no longer apply, including emissions compliance sensors (O2 sensors, catalytic converter temperature sensors, NOx sensors, etc.), axle speed sensors (largely used to verify the transmission is working correctly), vacuum line pressure sensors, etc.

    The result is that electric cars are much less likely to fail mechanically. Much less. In fact, one could reasonably argue that the reason auto manufacturers are dragging their heels is that, ignoring people who upgrade for appearance reasons or because their old car is too small to meet their needs, people are likely to replace their vehicles much less frequently than they do now. If the average person drives a car for 300,000 miles before they sell it and require no maintenance in the process, a $30,000 car costs only $0.10 per mile average, not counting energy costs. And that's a conservative estimate of EV longevity once we solve the problem of short battery lifespan. There's every possibility you'll have a rust hole where your feet should go before the electric motor or wiring gives out.... :-)
