  • That fantasy looks like the Western government offering tax cuts and incentives for a private company to set up shop in a rural town, hiring a bunch of employees for as little money as possible, cutting corners in safety and quality to boost their revenue from the investment, and ultimately delivering a shit product by comparison. Then, when the public finds out, the company will “downsize” by laying off most of the employees they hired, stranding those that are laid off in a rural town they can no longer afford to move away from while protecting the company’s profits.

    The CEO gets a bonus for record profits, a couple hundred people’s lives are ruined, a small town has to deal with the fallout of high unemployment and the socioeconomic issues that come with that, and the Western government is at a loss of millions of dollars in taxpayer funds. Lawmakers get their kickbacks from the company in the form of political donations and lobbying vacation trips.

    I’m sorry, my internet friend, but I have little hope for that fantasy without significant change to the system at large.

    When talking about AC power, some of the power consumed doesn’t actually produce real work. It gets used in the generation of magnetic fields and charges in inductors and capacitors.

    The power being used in an AC system can be simplified by using a right triangle. The x axis is the real power being used by resistive parts of the circuit (in kilowatts, KW). The y axis is reactive power, that is power being used to maintain magnetic fields and charges (in kilovolt-amperes reactive, KVAR). And the hypotenuse is the total power used by the circuit, or KVA (kilovolt-amperes).

    Literal side note: they’re all the same units, but the different sides of the triangle are named differently to differentiate in writing or conversation which side of the power triangle is being talked about. Also, AC generator ratings are given in KVA, so you need to know the total impedance of your loads you want to power and do a bit of trig to see if your generator can support your loads.

    The reactive component of AC power is denoted by complex numbers when converting from polar coordinates to Cartesian.

    Anyways, I almost deleted this because I figured your comment was a joke, but complex numbers and right triangles have real world applications. But power triangles are really just simplifications of circles. By that I mean phasors rotating in a complex plane, because AC power is a sine wave.
