That doesn't make consumption double for "traveling upstream" vs "traveling downstream". The "traveling" part means actually getting somewhere, not treading water. If you turn off your engine entirely, you will still travel downstream and consume zero fuel. The article is about the necessary specific context for the statement to be accurate.
- ptaipale 7y agoThere's a point about fuel consumption when travelling downstream though: you can't just switch off your engine and drift downstream, because you'll run aground fairly soon. The ship needs steering, and steering needs engine power and relative speed to water.
