    People are generally accepting of risk when it can put in terms they can relate to. If the calculated risk can be reduced to 1/30th chance of being struck by lightning, everyone will go for it, just as an example.

    But will the risk be that low? Lots of people are afraid of flying.

    Suppose someone gets ill in a sealed hyperloop car that's stalled
    between stations, with just vacuum outside? That could get very ugly
    and make bad press.

    Airplanes at least have a bleed air supply.

    I think the safety aspects can be dealt with. After all commercial
    aircraft also keep their passengers safe in a hostile environment.

    The site has a severe lack of interesting facts! It´s mostly fluff.

    The tracks sure do look expensive. A cost comparison between a km
    of traditional track and of a hyperloop track would have been useful.
    It would also have been interesting to know how they expect to get
    passengers in and out of a capsule, and how much power they estimate
    to sustain speed and to keep the tube pressure down.

    Instead they rave about cabine layout, composite material
    construction and other less relevant things. It doesn´t inspire any
    confidence they know what they´re into.

    That may be, but the total cost comes in less than an equivalent high speed rail build. The hyperloop has the unequaled advantage of nearly zero energy consumption. Looks like they're going after any market that would require a high speed rail, and they
    have commitments to build them out all over the place. They haven't built a single one yet. This Venice to Padua 23-mile route looks like it may actually materialize, but only as a 'validation' of the concept. How much dammed validating do these fools

    Fred's link provides a little information. A capsule is said
    to weigh 5 tons and is powered by internal batteries, With 40
    passengers and their luggage we might reach about 9000 kg.
    Bringing that up to speed, 1220 km/hr, requires about 280 kWh.
    That requires roughly 1600 kg of batteries if we're allowed to
    deplete them entirely, but more likely about double that to
    improve battery lifetime and to have margin for other purposes.
    That would leave about two tons for the capsule structure,
    motors and levitation magnets included.

    That looks totally unrealistic. Did I miss something?

    metric, I suppose. With 40 passengers and their luggage,

    Simple, running a tunnel 12 km deep or so. It's going to cost a bit,

    Such as slowing down again. ;)

    Completely missing the point, that the hyper loop concept uses gravity for >acceleration, and gravity for deceleration, and the 'kWh' value is identical >to the potential energy of the endpoints minus that of the trajectory nadir.

    The 1220 km/h is about 340 m/s, thus in free fall in vacuum 34
    seconds is needed to reach that speed. A vertical fall distance of 5.8
    km is required. Thus the module would have to run at least 6 km below
    ground between stations. Not very pract8ical.

    While gravity is used in local train and underground system design,
    the station is usually built on a hill or at least elevated from
    ground. Thus this helps accelerating the train leaving a station and decelerating before running into the next station. Thus some energy is
    saved.

    If a new station is required between two original stations (e,g, new
    housing or other centers) building a new station is sometimes refused,
    because of the new station would have to be built at the lowest point
    of the track, requiring extra power to accelerate from the station and
    extra breaking power is required when arriving to the new station.

    If the train can feed the braking power back to the network, the
    situation is not that bad.
