But they don't match the chrome wheels on your cadilac esplanade!

Drug dealers are fashion victims too

Pretty much standard for a royal wedding then

Have you tried public transport in London ? Or the local food.

It's also slightly tricky (understatement of the year competition) to hook up a 50Hz generator station to a 60Hz grid - if there are still 60Hz generators on that grid.

What happens is that the rest of the country tries to back drive your generator + turbine at 20% over it's design speed - this is a bad thing (tm)

It's hard enough phasing generators across the country when they are on the same frequency. The normal solution for long haul links, or links between different grids is to use a DC cable. The trouble is that people don't have spare Gigawatt AC:DC DC:AC converters lying around

Not quite - the US has a unique split neutral where an incoming 240V single phase is divided into +/- 120V to drive either 120V to earth or 240V heavy duty appliances. But the dryer supply in the US isn't a multi phase

There isn't really an optimal - it was mostly a set of accidents to do with already installed turbines and the number of generator poles in a particular design.

Lower frequencies were easier to build for early components, 50Hz is about the lowest frequency that you didn't notice flicker on a lamp. Almost all the early non-industrial use of electricity was for lighting - industry tended to generate their own power on-site using whatever equipement they happened to buy.

Telsa picked 60hz apparently because it allowed him to reuse clock mechanism in test gear. He also felt that 60sec/60min so 60hz was a 'natural' solution
