  • DVDs were released at different times in different countries or regions. Movie studios wanted to make sure they control those releases and you can’t just easily import and sell a bunch of DVDs from a region with an earlier release date.

    Of course there were DVD players that let you switch regions infinitely (and eventually just play all regions) or some people who had a second player for another region, but those were, at least initially, outliers. To make the general public wait to buy DVDs from their region it worked.

    Although, one could argue, it gave another advantage to piracy. Not only would a downloaded movie not threaten you with the FBI or make you sit through unskippable ads, they would be available as soon as their release in any one region, so you would have to wait (sometimes a lot) less.













  • Unfortunately „most people“ in this case includes you, but not me. But we can change that 😉

    The major differences between the Prius HEV and PHEV are that the battery has a larger capacity and that it can be charged externally.

    The transmission works exactly the same and on both models the gas engine can be used to provide traction to the wheels without converting everything to electrical energy first.

    It also has (at least) two electric motors - again, both HEV and PHEV.

    Look up Hybrid Synergy Drive on Wikipedia. There are also some good explanations on YouTube. It’s at the same time a quite simple, yet very smart design. I find it fascinating what the Toyota engineers have come up with.
