“Is Fungus the Plastic of the Future?

Plastic changed the course of manufacturing forever, but came at a cost. Mycelium technology might be the solution and the next big boom … a plastic-like replacement with so many uses and new opportunities for products, companies, and profits. Let’s explore mycelium technology and how it can help us achieve a more renewable and cleaner future.”

Pros and cons of Superadobe Earthbag homes…

“Who would have thought that sandbags could be inspirational? They were originally used for flood control and military bunkers but they have now been adapted for home construction. The bags are made of natural materials like hemp or burlap or more durable synthetic materials like polypropylene which is water, rot and insect resistant. These bags are filled with 70% sand and 30% clay and are laid in courses to build the walls, similar to bricklaying. The most common structures look like big beehives or igloos as the curved walls provide good lateral stability. The system has no tensile strength, so the structures must be built into compression forms like domes and arches. However, they could take on other forms like straight walls if they are topped with conventional roofs.

The earliest version of earthbag homes can be traced to Gernot Minke, a German professor. However, it gained momentum thanks to Nader Khalili, an Iranian architect. He established the California Institute of Earth Art and Architecture in Hesperia. Khalili developed and patented the superadobe building system, which uses mile-long fabric tubes that can be pumped full of soil and laid in coils to create a structure. He envisioned these structures providing temporary housing in case of natural emergencies or for low-cost housing. His most popular design is the Eco Dome, 400 sq ft structure that was featured on HGTV.

Advantages:
Both earth and the polypropylene or burlap bags are cheap. Also, you don’t need a large, experienced crew on site which cuts down on construction and contracting costs. Other than the bags and the barbed wire that holds the bags together, earthbag building is a natural building that doesn’t use any other resources like wood or metal. As for structural integrity, these houses seem to withstand seismic, wind and snow loads. They apparently also survive fires, floods and hurricanes. Also, if the house is properly plastered, it will keep out mold, insects, and rodents. Thermal mass is another.

Disadvantages:
Earthbag domes are the most structurally sound but it’s difficult to use space efficiently when the walls are curved. All your furniture and finishes have to be custom made. Size is another concern. The maximum recommended diameter of earthbag homes is 20 feet or 6 meters, however, you can connect these homes together or build underground to increase the building’s footprint. If you are taking out a loan, there’s a strong chance you won’t be approved for this kind of building with no precedent in the area, because you the lender can’t estimate your home’s value. Tied to this is the unpredictable resale value of the home. On the structural side, you must be careful not to use biodegradable material like leaves when you are filling the bags with earth, because this will disintegrate and leave gaps in your walls causing them to become unstable. If the sand to clay ratio on your site isn’t ideal, which it probably won’t, you will have to truck in mounds of dirt to your site. In Texas for example, where I live, the soil has a very high percentage of clay. Earthbag homes are also very labor intensive. Finally, the scalability of this model and how much of an impact this construction is really going to make. It is a potential solution for disaster shelters but it is difficult to mass produce these homes.”

Pouring molten metal inside a seashell – WHAT HAPPENS?…

“In this video I will be pouring molten aluminum into a seashell in an attempt to create a perfect casting of the internal structure. I started with a Marlin Spike seashell and made a simple sand mold. I then melted aluminum in my DIY home foundry and poured it inside the shell. I then broke the casting out of the shell and cleaned it up. This was a fun project and I may revisit this idea in the future.”

“The Future of Solid State Wind Energy – No More Blades.

Wind power is one of the fastest-growing renewable sources that works well at scale, but it isn’t perfect. What if we could scale down wind turbine power to something that could fit on your roof? And be self-contained with smaller moving parts … or maybe no blades or moving parts at all? Let’s look at some future alternatives for harnessing wind power.”

“Earthships are off-grid houses made of trash. These off-grid homes are fully self sustainable and do not require any utilities for comfortable living. Amazingly, the beautiful earthships are actually made out of garbage. In New Mexico’s desert town of Taos there is a large community of like minded people that dwell in earthships. In this episode we explore why they are there and why they choose this way of life.”

“When you think of North American cuisine, do Indigenous foods come to mind? Chef Sean Sherman serves up an essential history lesson that explains the absence of Native American culinary traditions across the continent, highlighting why revitalizing Indigenous education sits at the center of a better diet and healthier relationship with the planet.”

It’s tragic that this was lost to our people.

Went homeless. Done Guerrilla Grazing by choice ever since…

“Aaron Fletcher has grazed his sheep and lived off the land as a traveling shepherd for 12 years. He calls it guerrilla grazing (a step above guerrilla gardening, he says) and he lets his sheep graze – with permission- public parks and side lots. Homeless by choice, he offers his services to small farms in exchange for food or a place to stay (though half his calories come from his sheeps’ milk).

With a tiny metal cart home pulled by his sheep he has a bed, a refrigerator/evaporative cooler, a shower (he uses a pesticide sprayer to pump up the water pressure), power (solar panel), sun oven, a mailbox stove for heat, bicycle tire wheels and a corrugated plastic roof.

Fletcher makes cheese and butter from his sheep milk and forages for seeds, fruits, vegetables and herbs. He’s created a map for foragers in his region. He makes some money with his scythe business – cutting noxious weeds for locals -, but he insists he’s not interested in making money and just hopes to serve as an example for other homeless interested in guerrilla grazing.

I’m not crazy about a few of these things [going to the bathroom through/under the cart?]…but I’ve been eyeballing solar stoves like that, for a while…

…I’ve also used a clean [never before used] pesticide sprayer as a make shift shower…They do work…perhaps not amazingly…but it’s better than nothing.

I don’t know how much I’d really trust some of the food he’s just keeping around like that.

For a homeless guy, he’s got a fairly decent thing going on there.

I presume he’s not in one of the states with more brutal winters.
