In the video they are building the bricks on-site. I've done this before. And also built a kiln on-site with mud bricks (with a small team), though it takes a good design to get it to the high temperature required. Rammed earth is another natural building alternative where a formwork is built in-situ, infilled, and tamped down, once again with on-site materials. And from what I've seen it's absurdly strong, and can be polished such that it reflects like marble.
- justinclift 3y agoFor extra challenge, any idea if a solar kiln could be practically used for mud bricks?
- h0l0cube 3y agoYou need a temperature of about 1000°C to fire bricks, but more is better to get the moisture out. From cursory googling around it seems that a solar kiln wouldn't cut it, unless perhaps a very large solar collector was used... which upon further cursory googling yielded this: https://helioscsp.com/concentrated-solar-power-for-high-temperature-solar-process-heat/ https://helioscsp.com/concentrated-solar-power-for-high-temp... https://cordis.europa.eu/article/id/421794-the-next-solar-revolution-could-power-cement-production-with-sunlight https://cordis.europa.eu/article/id/421794-the-next-solar-re...
