Re: The critical question for river barges ... (4.00 / 2)
Ummm...being pedantic, rivers flow, and as far as I know locks on rivers don't usually have pumps.

So for "river barges" that factor doesn't really apply.

On the other hand, there's a lot of canals about, where in dry conditions especially, pumping is a factor in energy consumption.

But there is some new technology out there that's pretty efficient in energy terms.....

I've always loved those Thames river barges. There were loads in St Katherine's Dock which my office looked out over back in my days in the Belly of The Beast.

Re: The critical question for river barges ... (4.00 / 2)
Yes, its the lock to go from a river to an inter-river canal that is the one that would normally need pumping ... a bypass canal can almost always be built to simply fill up with the flow of the river ... but unless you are nominating a more energy efficient way for river barges can go from one river system to another, I am puzzled as to how that is not what I just said.

River boats have enough energy efficiency per ton of freight that we can readily consider home-grown biodiesel as a sustainable liquid fuel source ... as opposed to the fantasy of using biodiesel as a plug and play for petrodiesel for the existing truck-based freight system ... and having wind assist like above makes it an even better prospect.
