very cool! does anyone know what fraction of its energy consumption that it can produce on-site? i.e. the 1 MWh that it produces a day from solar panels, how many % are that of its total energy consumption for propulsion that day?

    i just calculated that 1 MWh is about 300 kg of fuel (that it replaces) a day. so in 2 weeks, that's maybe 5 t of fuel that it saves? that does not seem so much to me.

    It may not be much but it is something.

    They already run on crude instead of more refined fuel for very small percentage point gains in fuel cost.

    5t less fuel over 2 weeks isn't nothing, and this is the first one. With visibly a shit-ton more room for more panels.
