Learn to Build With Cardboard! STRONG, Waterproof and Free.
Added 2025-06-13 00:14:47 +0000 UTCIn this video we learn how to recycle cardboard into durable, waterproof projects that can be built nearly for free! This video will go live to the public sometime this weekend. In the meantime enjoy early access, and thank you so much for your support!

Thanks for sending! There's a few companies like this that make pcm packs. We'll see if I can do better with my own improvements in time.

2025-06-30 14:26:21 +0000 UTCHi Sam (NightHawk), I am trying to reach you to use your knowledge, input and expertise to assist us (universities and ASAQS) to make informal settlements in South Africa livable, using cheap materials such as cardboard. Most "mukukus" are constructed with scrap timber and corrugated iron. Freezing cold in winter (currently -1Β°C) and blistering hot in summer. You can reach me on bert@qs.co.za or on WhatsApp using +27 82 550 5199 Thanx, Bert

2025-06-28 08:23:44 +0000 UTCI am so excited to see this idea combined with the radiative cooling stuff. you probably already had the thought, but I wonder if using two layers of the corrugation could form a ocuntercurrent heat exchanger. or even using alternating "ducts" in the corrugation to flow in opposite directions. I'm not quite smart enough at that stuff to guess if it's a good idea, but by god it's an idea π

2025-06-26 13:25:07 +0000 UTCtysm for going down the DIY recycling path!! using the abundant waste around us is only going to become more and more important, and developing these easy open source techniques is such valuable work. I hope you continue pursuing different forms of abundant waste as input -- you are elite at solving these sorts of problems

2025-06-26 13:23:00 +0000 UTCI wonder how well a waterproofed cardboard roof would hold up against a season of rain and snow. If they can last a year or two, these construction techniques may be good for building outdoor shelters for my colony of feral cats. The layered corrugation should give some insulation, and cats are naturally attracted to cardboard boxes! Great video, thanks for sharing these ideas.

2025-06-20 20:23:40 +0000 UTCGreat video! I wonder if you could use the 'superwood' process (boiling out some of the lignin and hemicellulose, discussed here - https://www.nature.com/articles/nature25476) on your 'papercrete' pulp to make it even stronger.
