    I didn't say that such systems were new, I said they need to be designed for. IE the house/building needs to be designed correctly to impliment it.

    EG - rather than a 30 gallon water heater with 1" of insulation, you get a 100 gallon tank with 4" and a mixer valve that maintains a constant output temperature by mixing cold water in proper proportions when the tank is at its hottest. For the home, proper insulation combined with thermal mass can keep it at a comfortable temperature for hours and hours even without running the heat pump. Also, with such a system adding solar heating is a comparative breeze.

    Well, if he really said that, he's a dirty liar. You can trivially get 250HP from a 7.3 powerstroke, which weighs about 1100lb wet.

    What about the torque, and would the thing survive the stated 40k hours service life under such severe duty? He didn't mention that any old diesel would be 2k pounds, he mentioned it in the context of lifespan. I'm reminded of generators - standby diesel generators will rotate at 1800 RPM or faster, enabling more power generation from a smaller generator, but prime/continuous generators often operate at 1200 or even 900 RPM, drastically increasing their service life, but they have to be bigger to generate the same amount of power as the standby.

    The engine isnot receiving service every 3-4 weeks. A truck that unreliable would be sold for scrap. The most common point of failure is the hydraulic system. Diesel engines regularly run for literally hundreds of thousands of miles without anything more than regular scheduled maintenance service, unless they're six-liter Fords.

    You misunderstood what I said then. The 3-4 weeks was the regularly scheduled maintenance to do stuff like swap the oil and filters. It's not that the trucks were unreliable, it's just that they were used in such a severe duty operation that, much like NYC cabs, they ended up having to do oil changes on a frequent basis. The study was doing a lifecycle analysis using a different oil that extended the required service times substantially, even if the oil itself was more expensive, the increased usage time more than justified it.

    Like I said "is for torque". Torque, more than horsepower, is what gets a bus going. Meanwhile electric motors are great at low RPM torque, so while I'd go with a heavier duty motor for the bus, it doesn't actually have to be any more powerful, or even all that much heavier.

    The lighter weight of a Model S allows it to accelerate much faster, but the power demands are remarkably similar. Note that I mentioned that a Model S battery would be able to provide the current, not the energy. You'd get less range than a Leaf trying to drive a bus on all-electric with a single S battery. So what I was picturing was taking the electric drive-train of a Model-S and more or less converting it into the electric portion of a hybrid system for a bus.

    Diesels in that size are much more efficient, more tolerant of abuse, more tolerant of contaminated fuels, and a lot cheaper to maintain.

    Citation? In the video it mentions that a diesel replacement for the power of the turbine would be 2000 pounds, not 200. Not exactly the same size. He also specifies that the turbine requires less maintenance. The turbine(which shouldn't be running all day) is rated at 40k hours(4.5 years continual operation), doesn't use oil lubrication or have a cooling system to worry about. Service parts are filters - fuel and air.

    Looking up diesel garbage truck information - I found a study where they had a service interval of 225 hours, probably about every 3-4 weeks. The study mentions going with special motor oil containing stuff that enabled them to 'extend oil change intervals by six times'. So I think that figuring on an oil change between 1-3 months is reasonable. That adds up.

    As for contaminated fuels, is that such a big problem here in the USA? Besides, turbines are inherently multi-fuel, so as long as the fuel burns you should be good. If it doesn't even a diesel will hydro-lock and kill itself.

    I think that the trick is that you might be thinking of aviation turbines, not power generation turbines. Looking up the Capstone turbine company, they produce power turbines, not aviation turbines.

    The important bits I've heard about turbines is a bit that goes like "Small size, wide power band, efficiency, pick two". Aviation turbines aren't as efficient as they could be because they need to operate over a wide power band. However, the turbine isn't hooked to the wheels in this application - it can happily be either off or running in it's ideal power band charging the battery. At which point 1800 pounds saved DOES save fuel because a lighter vehicle can go further on a given amount of energy.

    Fun fact, last time hybrid buses came up because of Seattle's disappointing results with them, primarily due to new EPA requirements wrecking the efficiency of the diesel engines), I figured out that the standard bus has about the same horsepower as a Tesla Model S.

Especially when there's no solid evidence that said artificial works increase the odds that a child will be abused. My standard for banning something that doesn't directly cause harm to others is very high.

    Take drunk driving - I allow the banning of the act, even though a drunk driver isn't necessarily going to cause harm to somebody else, because there's mountains of evidence that the risks of them doing so is vastly higher. I oppose movements to drop the limits even more though, because it's getting into statistical insignificance. Drunk drivers are much more likely to kill somebody when they're over .2, not below .08.

The severity of their likely sentence drops if they're female or a different race, or are older. "Young Black Male" is statistically treated significantly worse than "Young White Male", but once they start passing into middle age the significance drops.
