ferrocement boat - concrete dinghy construction

from tightening the mesh, through mixing and applying the cement, to curing the concrete.

was living happily at home,
and then found out about seasteading, life on the ocean.

for life on the ocean have to have a long lived boat,
one that can take you through the strongest storms,
and beach effectively for repairs and foraging.

so I made a goal of having a floating island,
and decided to work incrementally,
started with making a concrete tablet,
then made something that could float,
then made a boat for a bunny,
now a dinghy.

I got the rebar tied it together with galvinized wire, then covered it with mesh.
the video is from tightening the mesh, through mixing and applying the cement, to curing the concrete.

Terrible camera work.

[lokadin]

@kofkok hey, btw, flat statements are rather useless. if you'd like to contribute then make suggestions for improvement. how do you think it could be improved? Consider that I'm holding the camera in one hand, while doing something and talking at the same time.

@lokadin Well, they'res two ways you can improve the video:

1)For your next ferrocement project, make a tripod to hold the camera.

2)Have a friend hold the camera.

3)Then edit using editing software so it flows better

[lokadin]

@MrTrailltrader 1) my next ferrocement project will probably be afloat, so it's unlikely that a tripod will help much. I did get a tripod earlier, one was too small, the other I lost the top part. 2) this is more viable, if I had a friend with lots of free time in the day, that was interested in participating, it's a task I'd consider delegating. 3) in terms of editing software, perhaps can add intro and ending text.

@Elzon1 ya, before claiming pykrete is "easy" I suggest you make a model and float it in your aquarium for a number of months, like I did with concrete boat model. anyways, if you're seriously interested in boat-building or living on the ocean, please join discussion at Seasteading (dot) org online forums.

@lokadin It doesn't need to be cold enough to support pykrete one can easily use insulation and a cooling system to prevent melting. The pykrete structure itself would be supporting algae photobioreactors. From there we can use the A.B.E. process to make butanol which you can use in a regular internal combustion engine. The acetone and ethanol can be burned so the waste heat can be used as energy while the CO2 produced goes back into the reactors. If we use low orbit reflectors its even better.

@porpoisefathom that is good to hear :-) hope you share your results. would love to see them.

[porpoisefathom]

this is an excellent way to make a durable- maintenance free- cheap boat--im working on making a pressure vessel out of it right now....great stuff FC....

thanks for the upload...

@kofkok I'd like to see you do better :-) In any case it's sufficient, what needs to be seen is seen.

@Elzon1 even Alaskan waters are too warm for pykrete, here is a more indepth discussion of pykrete on seasteading forums:

by contrast, concrete is a rock and can live long and be strong in any part of the ocean.
