I, for one, would like to see a critical exploration of the trinary intersectionality of (1.) ex tempore drummers and drum circlers, (2.) hippies, beatniks (and other "others" as may be found relevant and present) and (3.) cis-males with outrageous hair volume/length vis-a-vis a strictly Kyriarchist point-of-view, as it relates specifically and exclusively to late-stage utopian-socialism exhibited in the stratification of caste-like (and caste-less) social constructs in Dutch muck-raking in the early years of the 21st century, CE.

Oh yeah.... that will be a good GOOD reason for the Netherlands to import tons of refugees from all of Africa. And then you will have them all inside your little country forever. You've got a lot now. How's that working out for you.? Yeah. That's a really really solid idea. You morons keep thinking. That's what you're good at. Little else.

I was happy to find more interesting comments on this article over at Hackernews: https://news.ycombinator.com/item?id=17696507

Including a great idea:

"The horse powered dredge boats are interesting to compare to today's technology. They don't specifically give dimensions, but considering the space it takes one horse to walk, plus some extra space for dredging and boat functions, it is easy to place 750 watts of solar panels in the same space."

"You could make solar powered dredge boats which would be functionally equivalent to the horse boats. You'd only dredge when the sun shines, but you also wouldn't have to stop and change horses every hour and maintain dozens of horses per boat.You would get a good 4-5 months of dredging 4 hours/day, and you'd get to take December and January off! (or operate a fraction of an hour a day)."

"You'd need about 20 thousand of the boats to keep up with current demand, so that might be a traffic congestion problem during the summer months."

As was pointed out here:
& the next two articles

If you want to do serious amounts of work (in the physics Force times Distance sense) using human muscle power, you shouldn't do it 'by hand', but instead 'by foot', ie: use the leg muscles, the strongest muscles in the human body. The dredge mill mentioned in the article does that, but something using pedals would be better.

This technology which uses pedals to turn a screw propeller might be adaptable to your project.
If not it would still be useful for propelling small boats more efficiently than oars.

The clay in the river where I grew up is 85% alumina, so it used to be used for high alumina cement (HAC). Gangs of men used to dig the river bed at low tide to fill 100 and 200 tonne barges by hand, it was then sailed up river to the cement works. HAC is still used but only for non-structural concrete, it has crystalisation problems. There might be more uses for the silt in the Netherlands than just dumping it at sea,even for making more land.

Oh come on poster #1 and #2, give us a break. I for my part would like to thank all participants of the workshop for their effort, regardless of their cultural or ethnic background, and regardless of their taste of music. The original announcement for the Workshop was posted on this Website months ago. If I lived in Friesland, I might have joined myself... though I admit, other types of manual work seem more appealing to me. I think it is a very valuable excercise not just to talk about steps towards sustainability and make estimations, but really try something out in practice.



A better strategy rather than dredging the docks would be to extend the docks outward and let the sediment settle to new land. Like how new york extended itself over time or Port of Los Angeles which used the dredge spoil to extend the port.



"solar or wind power sounds unrealistic: those ships would require enormous chemical batteries, which is not practical or sustainable"

That's not the only solution. Diesel can be synthesized from air, water, and electricity, and run in the existing engines. There's loss in the process, but I expect it's what we'll be doing long term, to use boats and planes that can't be electrified. (As opposed to ground transport anywhere near a city, which can be.)
