  1. The thing with fungi is that they have been around since the dawn of time. They will survive the next extinction. They recycle detritus and are not overly demanding. A bit of moisture and some warmth and they just get on with things. Really interesting series.

  2. I wonder how mycelium would do as cooler insulation? it would probably need to be sealed on the inside and outside with some kind of hard coating. or maybe not and it could act like a zeer pot evaporation cooler.

  3. Not knocking the concept at all!
    But the idea of reducing shipping by growing it in situ is a false one. Unless you can farm nutrients from the regolith you will need to ship your own …. which because no process is 100% efficient will mean waste so you need more nutrient than mushroom!
    There is something elegant about growing a structure though ….. I like it!

  4. This is not to dissuade the fungal prominence in your latest line of thinking, it is to add ways to create the temporary structures that would be added to with mushrooms at the beginning. There are ' inflatable ' concrete structures. They are basically a form of canvas that has had dry mortar added and an air valve so that any gas can literally inflate the whole thing into shape and then water added to wet it as you would concrete. The structure would be solid in a few hours and cured ( on earth ) in a few days. The few videos I have seen claim that after 8 hours for the equivalent of a single car park ( garage for us in North America ) would be solid enough to cut openings in after as little as 6 hours as long as there was doors to put into the holes to keep the shape.

  5. In some ways .. mushroom blocks are like air-concrete made from foamed soap and some people also add Styrofoam bits to the mix .. it's not structurally strong by itself .. but if you use wood as your main frame then the wood becomes the strong part and the air-crete with Styrofoam beads become an insulating filler that can also apply stucco over. I've been thinking about this .. and wonder why not use some type of foaming glue instead of using concrete .. I don't understand the reason for the air-crete. Maybe in some cases the Aircrete is a good application .. YT channel "Stephen Williams" has been building a shop building with arches made from wood laminate and then filling the space between the wood with air-crete. Title of the video is "Styro Aircrete Garden Shed- Pouring and Packing the Walls". I like the process of inventing new and less expensive ways to create useful things. There are lots of Styrofoam that is part of the shipping of many different things .. so it is great to recover it make it a useful material. As I understand it .. mycelium feeds on the sugars .. as in Wood .. but might be interesting to see if it can be used with chicken wire netting etc. as a way to strengthen what you are creating.

  6. I would be surprised if there wasn't already multiple spores on the planets in our solar system just waiting for the right environment to start . Panspermia is logical when it comes to mushrooms because the spores are resistant to so many things like Radiation, drought , cold , pressure ect

  7. The growth of mushrooms will still take biomass, that biomass will have to still be transported to Mars. Mass can't come from nothing. Though it may be lighter than other building materials, it might not have the structural capacity to withstand the low pressure atmosphere of mars. Once we have a sustainable biomass factory (crops) on Mars, I think it will make more sense. It may be useful for furniture or other living goods in the short term though!! Since the spores can be confined in very small vessels it would be much more feasible then bringing a chair with you 😅

  8. We're already in that extinction event, unfortunately. =/ Hopefully this fungi-tech coupled with a move towards renewables will help the planet rebound. You've honestly shared enough tech and construction info on this channel to give us everything we need to make a difference as individuals. Your time and knowledge shared are greatly appreciated! Great vid! ✌️

  9. There is still the issue where you get the CO2 and the nutrients for the algae and mushrooms, so you need some solid ISRU.

    I really like metal electrolysis, especially the FFC Cambridge process where you electrolyze metal oxides in molten salt at low temperatures (comparatively).
    It can pretty much produce any metal from its oxides and produces O2 or CO2 as a byproduct.

    You basically only need the oxide cathode, the salt (CaCl2), a carbon anode, heat to 900 to 1100°C and apply electricity.

    All those things should be easily obtainable on the Moon and Mars.

    The carbon could be extracted from dry ice or meteoric rocks, not sure if you can make a graphite rod directly from carbon, usually it's made from needle coke. But it is possible to produce biocoke (as well as various hydrocarbons) via pyrolysis of organic materials.

    Lime(CaO) makes up 10-15 percent if the moons surface, chlorine could be extracted from some Apatite deposits on the moon.

    You can do it without the salt but it needs much more energy since you need to melt the oxide completely.

    You could also do carbothermic or hydeogen reduction, but the FFC is my favorite because of its simplicity and versatility.

    I'm imagining a plant on the moon that is heated/powered via concentrated solar power shining on high efficiency solar cells producing electricity and heating the reaction vessel.

    Or maybe using TPV cells shown on the channel, either the less effective 30% efficiency cells that operate around the 1000°C temperature or the 40% high temperature ones, because they are much more power dense. The latter would be 4 times cheaper to send to the moon but the system would become more complex.

    Except for the reflectors, the whole system would be pretty much solid state.
