I am extremely skeptical about your open flame idea, especially from a security standpoint and temperature control/maintenance. Also, if as another poster says 70% of the energy goes to heating then why replace this with a very dirty energy source? Kinda defeats the purpose.

Ye, maybe I should have written enclosed open flame. I meant some sort of protected open flame heating a tube of water. Is burner the correct term? Having a auxiliary diesel burner with water as medium is standard practice in the area. The buses have so large windows that the heating power is quite ridiculous. Maybe EV-buses need smaller windows? I tried to figure out how the buses and the article are heated and another article states electricity and oil burner when it's quite cold. (https://www.jamtkraft.se/om-jamtkraft/nyhetsrum/stadsbussar-laddade-med-fornybar-el/ https://www.jamtkraft.se/om-jamtkraft/nyhetsrum/stadsbussar-...) I don't think it's reasonable to heat them only with electricity in that climate. Maybe a wood pellet burner could be used if one is made for automotive use? I wonder if the pellets would bounce around too much ... probably only good enough in rural areas where there would be no smog problems. The specification demands on heating oil is lower, so you could make it from only tall oil (tree oil). https://en.wikipedia.org/wiki/Tall_oil https://en.wikipedia.org/wiki/Tall_oil

  Biomass or biofuel being renewable or good for the environment is debatable at best, especially when considering unintended consequences (like Brazilian rainforests getting slashed for biofuel crops).

    Obvoiusly the best is to not use the energy in the first place, but what renewable ("regrowable") would be better than biomass if heat is what you want?
