a term "steam" is not only used for Power preset, but also used for Tidal Water Turbine. I think "stream" should be used for Tidal Water Turbine(see the ​wiki page).
In English, this is not a huge problem. But in the other languages, this is quite big problem. In these languages, "stream" is completely different from "steam". This occur confusion.
