    They relied on a lot of cooling and in the theatre when they were up in the bio or projection rooms, any imbalance or bearing noise could become audible in the auditorium. To get the smoothest output (150hz ripple) the supply was 3 phase. In some theatres where their was a period between the 90 volt grid and the 415 volt star supply, the electrical companies supply was 200 volts single phase. In many or these cases, theatres used rotary converters.

    As power stations in the late 1960's progressively decommissioned their DC generators and supplied 11kv delta to the national grid, stepped down to 415 volt star for local distribution, the railways hit a problem. Massive mercury halls were constructed to convert the 11kv delta to 720 volts DC using a single transformer rectifier combination. On some of these, an oil filled transformer almost the size of a house, supplies around 30 mercury rectifiers similar to my picture. Most of them, including the London tube, now use metal diodes.

    Now, if we could only fix that 50Hz problem............it just ain't the right hum.....

    Most areas had a 90 volt DC supply at that time in the UK.

    All you need to do is full wave rectify the supply, ripple current has no affect on charging.
    Since AC measurements in electricity sales are RMS, the time factor would remain the same.

    It's not going to happen. It can't happen. It's impractical and unsustainable. Once they get people who understand how things work and how to build involved, ones who aren't financially incentivized to go along, it'll get revised.

    Meanwhile you gotta give em credit for working an effective scare campaign and then giving people hope with their "solutions", all to further the redistribution of wealth from the working class to the elite class.
    It's right out of the Marxist playbook of how to get the people under your thumb, and plenty of people are going "yeah, yeah, gimme more o' that!"

    Slightly off-topic, but from experience I can say that in past British built electrical systems are more resilient and reliable in weather conditions than anything created by US electrical companies. The Virgin Islands are the example, half is British, half belongs to the US. Guess which system almost never has blackouts and survives most hurricanes?

    ...it is in the British Virgin Islands.

    All these electric vehicles sound wonderful, but reality dictates the power needed for recharging has to come from somewhere.

    Yep, not only come from somewhere, but be delivered. While people wait. It's so easy to say that's okay, let em wait, but I doubt people en masse will put up with it. And I don't think that's a mystery at this point. According to reports I've seen recently, electric car sales are way down. And used ones aren't holding their value and can be had cheap as F (relatively speaking).

    Plus if you're a car/bike enthusiast, it's fun as F to throw A/F to the cylinders!

    Mentioned earlier was "clean diesel" - check out the GMC LM2/LZ0.

    "the redistribution of wealth from the working class to the elite class." That's what the whole system is about. It's always been thus. Why would the economic structure change to a more equitable system when it works so well for those that have the power and most of the money now? So mind your own business and ---BUY MORE. BUY MORE NOW.

    Friedrich Engels? No?
    It's good for a laugh every time some unread and uninformed lefty leads with the personal insults.
    Sometimes it's just all they've got. At least they know how to make a person seem learned.

    Their representatives may step in and call their schemes "imaginary villains" to throw the unwitting off track.
