    Its a really, really impressive stunt.

    But its just a stunt, with little practical use.

    During the whole demo, it probably spent less than
    10 seconds in the air. What's the max duration?

    What I want to see is it run the Nuremberg Ring.
    With downforce, and lateral jets aiding cornering,
    it will be interesting.

    The car has an air compressor in it, that is how it gets the suction for
    crazy four gravity cornering, so that it will never run out of
    propellant air. That is, until the battery runs out.

    Next model will address the problem through a partnership with Aerojet Rocketdyne. Now to find where to store enough fuel for a couple RS-25...

    If only we had electric vehicles with air compressors, capable of high

    You could even include some sort of automatic mechanism to attach
    several such vehicles together very quickly, and use the compressed air
    for a fail-safe brake.

    But how could you run electric vehicles without batteries? String some
    overhead wire, attach conductors to it and power it that way? Who would
    do that, sounds complicated, expensive (think of all that wire!) and
    dangerous.

    You could even include some sort of automatic mechanism to attach
    several such vehicles together very quickly,

    That will never catch on.

    and use the compressed air for a fail-safe brake.

    So much effort, surely it's cheaper to just crash every once in a while
    and settle any lawsuits from that?

    Well, a reputation, once acquired, does take some effort to uphold.

    When I was a kid, I visited my grandparents in Pittsburgh and asked why
    people didn't just put a pantograph on their car to use the power from
    the streetcar catenaries without having to pay for it. I never did get
    a good answer.

    It doesn't work for cars because cars tend to go "everywhere". It does, however, work very well for vehicles that keep running the exact same
    route repeatedly - e.g. busses. For instance in Zurich, Switzerland
    there are 6 bus lines that use trolley busses: electric busses powered
    via trolley poles from overhead wires. Perfect for inside-the-city
    public transport, being quiet and clean (no exhaust fumes or engine
    noise from a diesel engine). They used to have small backup diesel
    generators for short distances (e.g. when the overhead power wires were
    out or under maintenance), but these days they have batteries instead.

    Kind regards,
    Alex.

    Wires are not a necessary component of electricity. Have you seen the

    Au contraire. Not if you go the Xocyll route: the wire is electrified,

    Tesla's cybercab is reported to be able to use inductive charging
    (while parked above a pad), but I haven't seen photo evidence.
    It does have a conventional socket.

    Inductive makes sense for the cab, so it can charge autonomously.
    There's about a 10% loss in the system.

    Oh, you can get plenty of power if the distance between the two coils is
    small enough. The inductive charging system is a transformer, with the
    primary in the charger and the secondary in the device. Like all transformers, having a gap in the core (in this case two gaps, breaking
    the coil into two halves, one in each devices) makes it very lossy
    with losses that increase dramatically at low frequencies.

    So the key is to keep the gap as narrow as possible (under a mil
    hopefully, but a few mils can work) and the operating frequency
    as high as possible while keeping under Part 15 radio interference
    limits.

    You need a spring-loaded gadget under the bus so that the coil can ride
    right on top of the charging coil as close as possible. And if you are
    doing that, why not just contacts that plug in?

    Because then they won't learn anything. I contend that this type of use

    Telecom wires are certainly not on the same difficulty ballpark of
    exposed conductors delivering 25 kV AC, which also tend to be deployed
    high enough to provide sufficient loading gauge.

    Lower-voltage DC might already prove challenging, but 25 kV AC is
    certainly said to be a deterrent.

    Theft *is* a consideration, and that's why such electification tends to be
    left on 24/7.

    When I was a kid, I visited my grandparents in Pittsburgh and asked why
    people didn't just put a pantograph on their car to use the power from
    the streetcar catenaries without having to pay for it. I never did get
    a good answer.

    It doesn't work for cars because cars tend to go "everywhere". It does, however, work very well for vehicles that keep running the exact same
    route repeatedly - e.g. busses. For instance in Zurich, Switzerland
    there are 6 bus lines that use trolley busses: electric busses powered
    via trolley poles from overhead wires. Perfect for inside-the-city
    public transport, being quiet and clean (no exhaust fumes or engine
    noise from a diesel engine). They used to have small backup diesel
    generators for short distances (e.g. when the overhead power wires were
    out or under maintenance), but these days they have batteries instead.

    Kind regards,
    Alex.

    One system proposed for cars with batteries was to charge them
    by induction from cables laid beneath the road way. The cables would
    be powered by roadside solar panels and wind farms.

    I don't think our San Francisco Trolley cars or buses have
    backup batteries. Right now they are having trouble keeping enough
    buses running due to revenue shortfalls hopefully to be supplements
    by a tax measure on the coming ballot.

    We still have lots of diesel buses running on heavily travel
    routes. But not enough on weekends and holidays. We MUNI riders have
    to travel those routes on weekend packed in like sardine but without
    more oil. It was 82ø F in San Francisco today and must have been
    hot for standees.

    Contacts that plug in can be as presently in all electrical

    I don't know if these were ever built but they may have been in
    Japan.

    Not something to mess with lightly. And yes, they're have been accidents
    with fools standing on top of railway cars, getting to close to the
    overhead power wires and getting fried.

    The trolley busses are at a more moderate 600V or 1000V DC, but then those wires are in the middle of the city, much harder to nick them without
    people noticing you or the police showing up.

    Kind regards,
    Alex.

    You need a spring-loaded gadget under the bus so that the coil can ride
    right on top of the charging coil as close as possible. And if you are
    doing that, why not just contacts that plug in?

    Contacts are messy: they are in an environment exposed to water, oil

    Contacts that plug in can be as presently in all electrical
    cars that do plug in and are thus protected by design.

    But those tend to not be built into the pavement to rise up on demand
    and plug in from below. Just a nicely covered charging port on the side
    of the vehicle and either another nicely covered port or rolled up cable
    on the charging station. Much simpler to keep clean.

    It doesn't work for cars because cars tend to go "everywhere". It does,
    however, work very well for vehicles that keep running the exact same
    route repeatedly - e.g. busses. For instance in Zurich, Switzerland
    there are 6 bus lines that use trolley busses: electric busses powered
    via trolley poles from overhead wires. Perfect for inside-the-city
    public transport, being quiet and clean (no exhaust fumes or engine
    noise from a diesel engine). They used to have small backup diesel
    generators for short distances (e.g. when the overhead power wires were
    out or under maintenance), but these days they have batteries instead.

    Kind regards,

    One system proposed for cars with batteries was to charge them
    by induction from cables laid beneath the road way. The cables would
    be powered by roadside solar panels and wind farms.

    I don't think our San Francisco Trolley cars or buses have
    backup batteries.

    The ones with battery backups here are the newer generation - it helps
    that Zurich tends not to be that short on funds. Before that, the
    standard backup power was a moderately sized diesel generator in the
    trolley bus, so it can move at some moderately slow speed if it has
    no overhead power availabe - as opposed to not being able to move at
    all. I would assume the San Francisco trolley busses to have those
    diesel generators.

    Au contraire. Not if you go the Xocyll route: the wire is
    electrified, rounded by razor blade barb wire, and there will be
    some no trespassing signs too.

    That doesn't seem to be stopping the current thieves....

    Let's rephrase that to "stopping the thieves currently doing so" since
    current thieves just steal the electricity.

    Telecom wires are certainly not on the same difficulty ballpark of

    high enough to provide sufficient loading gauge.

    The VAST majority of primary circuit wiring (12kv and higher) is

    Using tuned magnetic resonance it's possible to charge with a
    considerable air gap with acceptable losses.

    IIRC power transfer has been demonstrated at at multiple meters! at
    lower power level and there's multiple *commercially available* system
    that handle high powers (enough for EV charging) at different maximum
    distances up to at least 25cm.


    There have been, on and off, experiments with embedding inductive charging >>coils at bus stops right where the bus is sitting to charge the batteries >>of battery-electric busses, but TTOMBK none of those have been deployed
    for production use.

    You need a spring-loaded gadget under the bus so that the coil can ride
    right on top of the charging coil as close as possible. And if you are
    doing that, why not just contacts that plug in?

    The setups I've seen all use pads embedded in the asphalt/concrete,
    usually handling a gap between 10cm and 15cm - which for stationary
    charging is a range that many? most? kneeling busses can down into
    already so it doesn't even need additional hardware for that. And
    those are common these days (for accessibility).

    If necessary there's at least one that can do at least 25cm and AFAIK
    the "on the run" charging setups are set up to handle even higher gaps
    but both of these are less common.

    Usually the system can handle about +/- 10cm lateral and longitudinal misalignment without big losses in efficiency and will only charge if
    it's sufficiently aligned. Usually this isn't hard to arrange but
    there's systems where the charging pad can actually move a bit to
    align itself when it's too hard to make the vehicle align itself but
    it's close.

    Transfer efficiency is usually in the 85-90% range, which means that
    active cooling might be necessary on one or both ends.

    Example:

    Oslo, Norway had a couple of test busses with inductive charging a few
    years back, by all accounts it worked exactly as claimed BUT Oslo
    instead went with overhead charging for all their electric busses, it
    looks like a Pantograph but clearly must have two poles. I suspect
    this is both cheaper and have much lower losses.

    Most of the busses charge exclusively at various yards (overnight and
    when the driver takes a brake), but some longest high-volume lines
    have short overhead wire setups at one or both end of the line stop
    where the bus stays while the drive takes the legally required break.

    Yes, this require a few more busses than swapping the driver at the
    end point, with the driver taking a brake and then taking over the bus
    coming in after their break is over like they did before. Electric
    busses aren't cheap but honestly it's not a big extra cost needing a
    few extra and they're also save a lot on fuel.

    Elon's original idea was to use a compressed air rocket to add
    straight-line acceleration. However it was pointed out that using the
    (then) rocket to increase downforce would be more effective for reducing
    0-60 or 0-100 acceleration times than using the rocket to accelerate the
    car.

    The endurance is tiny, iirc in the initial concept it was a few seconds
    only. It also takes a long time and a lot of battery power (compressed
    air rockets are very inefficient, to put it mildly) to recharge the
    compressed air cylinders.

    The kinematics and thruster control are, I assume, developed from the
    SpaceX booster soft landing software (probably inspired in part by the
    Lunar Landing Challenge).

    An impressive stunt - but only a stunt.

    Straight propellers (possibly in conjunction with ducted fans) are the
    way to go - there are quite a few experimental and semi-experimental
    vehicles using them now. Not quite flying cars, as yet, but flying cars
    are technically possible.

    The main reason nobody has developed a mass market flying car is that
    you would need a pilot's training and license to fly one - no way is the
    FAA going to let a non-pilot use a "self-driving" or "self-flying" mode, especially as we don't even have a proper self-driving mode for cars for non-drivers.
