Buy an electric car!!! ...And make sure you have the latest and greatest $2400 disposable phone so you can sneak in the trash 2 years from now. I guess with how things are going, by 2030, we will probably need the landfill lithium from the phone and auto industry seeping into the groundwater anyhow just to keep people "level". They point at the air and tell us we need to fix it while they pollute everything under it making bank on generating solid/soluble wastes. Removing the right to repair is China's payback for recycling. --- End quote --- think lithium is worse than lead? there's only about 5kg of lithium in a Tesla battery |

The Japanese factories I visited always had both power frequencies available for production test. --- End quote --- It surprises me that they haven't merged this by now. Most 50Hz gear will work just fine on 60Hz although the other way around is not always true. These days inexpensive point of use frequency converters are feasible for things like clocks and timers. --- End quote --- The factories I visited made higher power equipment, where the frequency matters and one needs to verify that the equipment works on the supplied line frequency. There are lots of high-power motors out there in industrial applications that need to be specified for the line frequency. It was my opinion that this gave the Japanese companies an advantage when exporting to both 50 Hz and 60 Hz countries. |

https://en.wikipedia.org/wiki/Utility_frequency#History -london had 10 different operating frequencies before regulation and this are also somewhat relevant https://en.wikipedia.org/wiki/Phoebus_cartel https://en.wikipedia.org/wiki/War_of_the_currents |
