Charlie is an absolute natural in front of the camera - thanks for repping the US at Project Kamp Charlie!

[@GreenJimll]

Nicely done. Emma and Charlie seem to make a great construction team together.

[@adaffro]

I was just about to say they seem like the dream team in terms of constructing to a high quality!

[@casucasueq4479]

Emma is a superstar.

[@IDontWhantAUsername]

Emma is a great asset for the camp

[@artofcode]

You might want to cover up the intake of the shower drain with a grate to avoid debris of too big size getting in and blocking the drain somewhere you can't reach easily.

[@Biohazardcube]

You could put plant carbon (use mimosa) on top of the concrete structure as a filter barrier and cover it with coarse stones.

[@ChemistTea]

Yeah, that seems like an easy thing to add that would be worth it.

[@pete3897]

Just stuff a big "scotch bright" (steel wool pot cleaner) in the end 👍

[@Isaac_Norman]

Also, if you want more privacy, you can install a second layer of the pine boards on the interior of the shower below the shelf. Offset the boards by at least 3 - 5 cm and it will possibly help both sides to last longer while providing sustained privacy as the boards shrink over time.

[@fjkelley4774]

@@Isaac_Norman Could use exterior battens over the gaps, but given the original width of the boards, might be alot of work. However, the pine will definitely shrink over its life.

[@franceswatts4001]

That shower is a work of art! Love the staggered heights of the wood planks, the shapes of the shelves, and the stark contrast of the pipe work.

[@JonCole]

big fan of charlie already!! hope to see him more on the channel :)

[@arieveloo9808]

Yes Jon that is what I hope to!

[@pv-mm2or]

not only as hard a rock but waterproof, 2000 years ago the romans were using such exotic mix's one of which was volcanic ash, it was used to build aqueducts, domes, water catchment tanks and much more, after 2000 years many structures are still standing and working great, no leaks! no cracks!

[@meinmaine9138]

Emma and Charlie are super talented! Great job on this project.

[@whitefam2000]

I was suprised you didn't torch the ends of the posts that were being put in the ground directly in the dirt. Good method for preventing rot, or at least putting it off for a longer time than it would be without it. Very happy to see the Magnesium Oxide experiments and how it works. The only thing I could think to suggest would be to put in a drain screen over the runoff hole in the ground, to keep large pieces from potentally plugging the drain. Where you have it, it doesn't seem like it would be a problem to clear out, or check once a week, or more, depending on the usage of the shower. Loved the project. And yes she is already a celebrity. 😁😉

[@BadgerBishop]

It's so wonderful watching you all come together and make iterative improvements to your community spaces.

[@ChemistTea]

Charlie seems great. Nice shower, huge upgrade and life improvement!

[@RandomBro5]

This guy is a great addition to the channel!

[@rbu2136]

FYI, there’s been lots articles about the discovery of the ancient Roman self-healing concrete technique. Especially when used around water. Hot-mixing.

[@lastSKYsamurai]

So good! Absolutely fantastic stuff everyone. Q. Any Clay Pits on the land? If you could make your own clay pavers, fired in a kiln, that would cover any long term issues with mud across base camp. In fact just constantly sourcing discarded bricks/tiles/pavers & laying down a patchwork network of covered areas would be an extremely effective way to keep the dust & mud away.

[@Biohazardcube]

Nothing to say, besides nice planed and cutted video!!! Progress of Video quility is great! And well made wooden work!!!

[@rolandtb3]

Some ideas to prevent wood post rot and water runoff in post area: Propane torch the wood surfaces, stone/brick/concrete/rocksbelow and around wood footing, concrete or similar base pad for wood to rest on, or rock base to improve drainage away from post bases, sand/clay/mud and hay/straw; once hardened, apply a smooth sealant (concrete or other). Takes longer but some make their own air dried bricks ( straw & mud in a mold) and use mortar or equivalent to join. Any plans for a passive roof solar water heater tank storage unit. Eg, Water tank on the ground, exposed to the sun yet glass covered or encased? Solar panels on the roof to provide an alternate energy heat source, shower roof water run-off collected in blackened water barrel(s) on the ground. Water can also be used for garden plant drip irrigation.

[@PTEC3D]

It looks FANTASTIC! The wavy tops of the palings turned it from a utility area into a pleasing feature, and with all the new facilities you won't know yourselves. And the research with the alternate concrete - wow! I'm definitely putting MgO concrete on my list of handy things to know! Seems to have some great properties. Nice to see life becoming more and more comfortable in Kamp, thanks again for sharing another great episode.

[@rmcdescabelado]

It would be nice to reuse the gray water from the shower. I know you guys don't have any lack of water, but the planet would thank you for that. Gray water can be used for watering plants, washing clothes and so on. Good luck!

[@Freak4Fun060690]

Dave you are looking good! Less "tired" as in some other update videos from Season 1/begin of 2. Hope I am not mistaking. Thanks for the great content every Monday. Lovely start of the week. Love to all the others is camp!

[@kearnsey64]

That was awesome! With all the manual labor there, a hot shower at the end of the day is a blessing!

[@margakat]

I love what you all do. I am a patron supporter. But I don't watch a week ahead because I want the videos to last. I know the winter is coming.

[@wadeprior5203]

You guys are doing one heck of a job keep up the good work have fun you guys in Alicia got a shower and I'll make one thing at a time God bless you guys keep up the good work

[@debbiegarza1287]

That shower was a piece of art!! Great job.

[@ryanm2648]

The magnesium oxide experiments were super interesting! Thanks for including that. I've worked with building supplies in the past - I did a year of work almost exactly like this. I never heard of using this for cement. Clearly it works, though, and is much better for the environment. You might want to add one more layer that is all downhill to the drain. Normally you have it all sloped, so water drains and doesn't pool. You can use a small spirit level to get it near perfect! But you really need to make sure the basin is all downhill to the drain, as otherwise the water will eat through the magnesium over time or go stale. It will certainly make it sink down, and drop further. Also add a grate over the drain to allow you to easily clean it in the future and prevent blockage, you will get a stink otherwise. Good luck!

[@camielvanlenteren5256]

potassium Phosphate, or fertilizer, also has a huge Co2 footprint, or is that very much lower than cement?

[@takeahike858]

I agree with Camiel the CO2 difference is likely negligible when you account for shipping and packaging. Etc. This Carbon boner nonsense smh

[@ryanm2648]

@@camielvanlenteren5256 Cement is one of the biggest producers of CO2, because not only does it require combustion, the reaction itself releases massive amounts of carbon due to the carbon atoms breaking off elements that have many carbon atoms. This is why it's good to look for alternatives. Potassium phosphate may be better, as it can be produced chemically with little carbon output. That being said, it's very likely that it's no where near as good as cement and will breakdown well before it. The better solution is to pump cement with CO2 so it is trapped inside the cement. Many companies are doing this as it's easy and quick and can store a lot of carbon. But for a small project like this? I think that using potassium phosphate may be better. It isn't large scale.

[@purdypart]

​@@camielvanlenteren5256 check out fumed silica instead of phosphate

[@huntakilla1234]

New shower looks great. Emma & Charlie did a phenomenal job 👍

[@arieveloo9808]

Yes looks like a super Team!!!!

[@cutekitten4395]

The new shower looks amazing and the magnesium phosphate "concrete" is super interesting, thanks for the awesome videos

[@cathybrewer8958]

I like the shower before the materials and setting it up. But this one is so much nicer. A good upgrade. Great job guys!

[@erictjones]

I love the chaos and problem solving. You should already be thinking about improving this one!! :)

[@darshiniyoga]

WOW! One of the best videos in a long time!!! Very good timing with the music and smooth. Like it 🙂 Thank you very much. 😀Big hugs.

[@daylen577]

Do you keep a log of everyone who's come and gone, what they contributed to, and which videos they were in? If so, any chance you could put this on the website? Would be neat to track every person's contributions, not matter how small, just to see what it's like for everyone and what their roles are

[@BallisticTech]

Perhaps they could look into an open source wiki and views could contribute these types of things

[@mattbray_studio]

loving the music in the videos of late. great job editor!

[@moanahughes3593]

The sustainable element is in the materials ability to return to the earth and be replaced by your labour. We had a deluxe long drop (two holes in the board, nicely smoothed for no splinters and no queues 🤣😂) just dig a new hole every year. Got twenty years out of that tin shed before indoor plumbing...

[@alansomerville4806]

Ditto the grating. BUT! The top of the shower walls, just love the untrimmed nature of the ends of the boards. Almost looks artistic.

[@dddilworth12]

Super-cool! Thanks for sharing the process. Really excited to give some of this a try. (Also: Y’all have one of the grooviest soundtracks EVER!)

[@tomaldous6192]

I just had an idea for you, with all mimosa sapling you could make walking sticks and canes and sell them around different climbing trails in the mountains. For sure you have enough of them on your property so you would never have to import them.

[@braamjooste1]

When you start doing plumbing indoors remember to pre-squeeze the copper rings (olives)on the pipes, also add a bit of thread tape around the olives before final assembly, this will make sure your fitting dont bleed later on. What do you guys do with the grey water? Understand you use bio soap but does it run through a fat-trap before it goes back into the wild?letting the water flow into a pit/ with potato sized rocks can do the trick, the body fat sticks to the cold rocks and you can treat it with bio enzyme to clean it up and take the smell away, I enjoy your videos, thanks for the great content *cool music video man*

[@andreafranco8812]

Great man!

[@direct2397]

Love comments like this. Very informative.

[@patrickdoolan2256]

look forward to your videos each week. never disappoint.

[@davidwilson1043]

I like the improvement you keep making. I also like to see the personalities at work. I also hope all the friendships you make last a lifetime.

[@nixonnelson5181]

you could have used the bamboo to make threads and make fabric of the bamboo then being cross stitched the warp would be minimal and some kind of waterproofing can be done using some other material.

[@user-gz8zo5vo9l]

Commenting to make the video get bigger bigger! Great video ♥

[@SilverGoth]

I really like what you're doing with people recording their own projects. This video was very satisfying to watch because we got to see the whole process including the result. Your shower is beautiful!

[@PaulGriffith]

If the linseed oil finish doesn't hold up in the shower, try tung oil. My dad finished a picnic table with tung oil and it lasted for years.

[@arieveloo9808]

Waaaaw Charlie is a great builder and what a nice guy!!! Love the girl too!!! What a beautiful shower!!! They made a great job!!!

[@albinendler]

After visiting, your website and reading your mission I just decided to become a patriot and donate, 5$ per month. Also recommended the channel to 4 friends. I think you guys could mention this mission more often in your videos, (maybe in one or two sentences at the beginning of each video?) Gives the whole thing more context and maybe even more people will become supporters. convinced me at least 😍 love.

[@T_Barb]

Charlie is from the states! Hey Charlie! As usual, amazing guys. So in awe of you.

[@marissinka9775]

The environmental impact of Magnesium Phosphate cement (MPC) per kg is higher than for Portland cement, mainly due to the use of fertilizer. It, of course, depends on the ratio MgO:phosphate and other variables, but please, don't advertise it as "environmentally friendly" which it is not. But a great material for superfast setting and very useful for such a project.

[@jessicauribe4086]

Love the shower upgrade and cement alternative information!

[@ElderNotleh]

One of the best videos! Love the experimentation with alternative materials.

[@fearlyenrage]

That is also a form of "Geopolymer" You should deepen your studys into them, a fantastic topic. I repair all around the house with it because it will outlast cement for centuries. Roman cement is a very interestig topic to.

[@lurchie]

I LOVE the materials research. I'd love to see more videos like this!

Charlie is already a great asset to the kamp. Can't wait to see his next build!

[@romanbuchberger]

wow! Love the alternative concrete experiments and the whole build, Charlie fan already! In case you haven't thought about it already you could put some rocks or rubble in the basin to act as a natural filter. Keep hair, leaves and animals out of your pipes.

[@sevenfx9687]

i hope i can do this some day its a literal dream. thanks for the videos they're amazing truly!!!

[@PauloJRSantos]

Don't let the water tank goes dry, even in winter time, but specially in the summer, otherwise it will crack and start leaking. Just 5cm of water will prevent it! Nice work 👍

Great work on the show you guys. Just a suggestion to stop those boards twisting. Keep a constant middle rail going around with an angle for water to run off. (Joiner carpenter here) love the different idea on the base product. How firm does it stay being wet all the time?

[@Alexdelannee]

Nice upgrades you are doing! Cool to see how you take into account the materials you are using and share the experience and experimentation.

[@JoopKarelSpank1]

so im catching up on the Project Kamp videos and although 8 months late i do like to comment on the carpentry work. I love the work you guys put out but i have one concern. As a former carpenter myself i am used off seeing a lot off workers using really loud tools without hearing protection. Which will set a trend so new people on the jobsite will follow the example and refrain from using hearing protection, giving arguements like being able to better communicate. If you want to work in a sustainable way to preserve yourself and your coworkers i think hearing protection is a good way to start. If you look into db output from powertools this would be a good idea even using power drills and impact drivers but especially oscillating saws and miter/track saws. I know this can come accros as being a bit nitpicky but i can speak from experience that oscillating saws with inadequate protection can give you hearing damage/tinnitus

[@brendansharp4856]

I’ve seen mixtures or concrete that use wood chips inside if you want to consider that! Acts as a carbon storage because the emissions of the woodchips biodegrading dont happen. Could be interesting to experiment with!

[@sshaw4429]

[@empresspyra]

There is an old poem and a rule with linseed oil - I applied linseed to a wood floor in a bathroom and those 2 coats water proofed for over five years but the ancient Victorian era poem said of coats of linseed on wood: "once a day for a week once a week for a month, once a month for a year, once a year for a life time :p and a couple centuries later there's still a wealth of functional unfaded pieces of Victorian era linseed oil furniture kicking around- so my reply to your efforts is (may that shower stall lumber outlive all of us) (and it actually could if you apply the principle)

[@AngelFontenlaGago]

Great video this time I'm definitely checking out the research module!

[@YousefDana]

Best video yet. Great editing, pacing, content, and design! Also biased because I'm a civil engineer and I love concrete and alternatives. Try looking into bio-concrete!

Would love the help if you ever come this way. Zion, Bryce Canyon , Grand Canyon, cedar breaks, escalante staircase. The wave. You get the idea. And the offer goes for anyone else when your time in Portugal is over

[@rubenpolle123]

love the chill background music you guys put in the video.

[@adamlancer9997]

Loving tho project so far, as a suggestion you might want to look into charring the surface of any wood that goes into the ground such as the posts in this video or the mimosa that forms the steps. Charring the wood prevents bugs eating it and prevents rotting, plus it looks really good IMO. It's originally a japanese method called Shou Sugi Ban, plenty of videos on youtube about it :) . + It is also more fire resistant.

[@ziad_jkhan]

Thanks for suggesting. Here's an interesting video about it: watch?v=J4quKHOxucY

Really enjoying the material experiments.

[@milliams]

At 8:10 I was expecting the camera to pan round the rest of the Kamp standing there watching :D

[@guib7852]

Great work. One thing to remember, both magnesium and potassium are flammable, have you tried doing a flammability test on the new material? Considering the area has previously suffered from forest fires, sounds apt to ensure you are not putting a potential bomb in your shower basin.😅

[@alpaykasal2902]

one major downside magnesium oxide cement, it does not hold up in wet / aqueous environments. I'm curious about how long it holds up as a shower basin. Wishing you the best.

[@noahfrazier4813]

Love it! One concern: won’t the mulch turn into mud quite fast? Maybe some “concrete” stepping stones set into sand would stay drained and clean

[@Barbaralee1205]

Love the new shower. Really nice!

[@darinmbicknell]

Nice. Love the drain pan.

[@eggos5074]

Suggestion get a couple of rocks that are sflat and just push them into the ground but still be above the ground level that way you have a stone to walk on coming out of shower.

[@luella2u152]

Love these videos. Project Kamp reminds me of the early days of The Mother Earth News commune. I love seeing all the innovations. I hadn't considered all the effects of cement or concrete on the environment. This was a very informative and fun video. Keep it up. Love the new and improved shower and sink area.
