  Don't look too close at spinning wheels failure modes. The fact is that for most applications, there isn't enough technical difference to justify either of the options. It's all path dependency based on random choices made ages ago.

    > Don't look too close at spinning wheels failure modes. It's a sealed turbine, not a "spinning wheel." It's failure modes, while internally destructive, are often limited to the device itself, and trips are much easier to install and utilize in this path. Dead short DC failures have a tendency to destroy nearby equipment and start fires as well. You're also going to need a bank of capacitors, so you've multiplied your failure rate for each capacitor required. > there isn't enough technical difference to justify either of the options There's a massive amount of difference and AC is obviously justified. > based on random choices made ages ago. You don't seem to be aware of the history of the power grid and how we've arrived at the technology we have.
