Actually, tweets of the day.<\/p>\n

It’s a tweet storm on why Japan is the only industrialized nation to have two grids operating at two different frequencies:<\/p>\n

Just learned a real-world example of the cost of \u201cmeh, we can refactor this later\u201d:<\/p>\n

Japan is the only modernized country in the world to run on two independent electricity grids, by historical accident. When the 2011 tsunami happened, half the country was knocked off-grid…<\/p>\n

And the other half was unable to help out, because the two grids run on different frequencies.<\/p>\n

How did this happen?!<\/p>\n

In the 1800s, Tokyo entrepreneurs bought a 50 Hz generator from a German company that would later become AEG. Osaka bought one from the US that ran on 60Hz.<\/p>\n

This design is a reflection of the political facts of the era: power was consolidated in the hands of local authorities. Centralization came later.<\/p>\n

In the world wars the Japanese government floated the idea of unifying the two grids, but ultimately the idea was dismissed because \u2014 you guessed it! \u2014 it was too expensive. Also, the cultural rivalry between Tokyo and Osaka didn\u2019t help.<\/p>\n
