I like the idea of a wicker basket coffin with natural-fiber clothes....and an added sword just to confuse future archaeologists •ˋᴗˊ•
Keeping a lid on your carbon footprint doesn’t stop with your last breath. Your choice of funeral can have a significant environmental impact. In a recent report by the US-based National Funeral Directors Association, 60.5% of those surveyed expressed their interest in greener options including resomation (water cremation) human composting and natural burials.

I debated for a while on if I should post this or not (rather morbid, I know) but I think it's an important thing to think about.
I could be wrong, but I don’t think you can grow all plants in hydroponics. For example, anything that grows on trees(large root systems) as well as grain crops (where you need a lot of plants together, rather in individual pods like in most hydroponics).
The only alternative I can think of is a greenhouse system. Like what indoor botanical gardens use for trees, but instead designed for farming. That would be expensive(more than farmers could afford), but it would also weather-protect crops.
But you are right about hydroponics or aquaponics for a lot of produce, though!

As far as I know (I have never 3D printed), yes. I vaguely remember a guy who tows around a 3D printer on his bike into parks, and prints parts for people. It wouldn’t be instant(I’m guessing they tell the person to come back later), but it is possible. I’ll try to find the video haha.
Keeping in mind I’ve never 3D printed, here are some sites that look promising.
https://www.traceparts.com/en https://grabcad.com/library
Also, I’ve seen tutorials for 3D printing on Instructables, and people sometimes give download files in the instructions.
They go off of who volunteers. For example, if a person who specializes in fixing stand mixers volunteers, that will be one of the tables people can visit. That repair person brings the parts (for example, there are a few parts in stand mixers that tend to break, so the repair person would know to bring fixes for those). I have also heard of repair cafe's elsewhere even bringing in 3D printers to help with part replacement.
Here is the text from a recent one in my town:
Items that are accepted at Repair Café events:
- Electronics such as gaming consoles, CD player, DVD player, camera, adaptor cord, etc.
- Small appliances such as toasters, coffee makers, lamps, waffle makers...you get the idea!
- Smaller pieces of furniture such as small wooden furniture pieces, a clock, or a plastic item that needs some crazy glue.
- Toys! Whether it needs glue or some wire soldering, we can try to repair it!
- Clothing or housewares (clean please!) that need mending. Full alterations will not be done.
Items not allowed:
- Microwaves
RIGHT TO REPAIR
A big fight is happening world-wide to push governments to ensure people can repair the products they own.
“The right to repair refers to proposed government legislation to forbid manufacturers from imposing barriers that deny consumers the ability to repair and modify their own consumer products.” | Wikipedia
This is happening because of:
- Planned Obsolescence: companies are purposely building their products to break faster, so you have to pay to replace them sooner.
- Unfixable Products: some products will have their components soldered, glued, or riveted, to stop people from being able to repair.
- Brand-Specific Parts: These parts may cost more than buying a new product. As well as that, some companies refuse to let independent repair technicians purchase their parts to try and force costumers to only use the product company for repairs.
- Restrictive Programing. For these, the programs refuse to let you fix your own products (a large example of this happens to farm equipment, where farmers have to hack their own equipment if they want to repair on their own).

REPAIR CAFES
Repair cafes are typically community-run events where volunteers gather to fix the broken items of strangers for free. My town started doing it a long time ago, and it was so popular that it now happens several times a year.
People bring in stand mixers, vacuums, computers, items that need sewing repairs, and more. Often, the person is very willing to explain the repairs as they do them.
In other places, repair cafes have become more permanent. For example, in Austria, the government started paying those who repair.
Repair cafes not only save people money, but they also can greatly reduce the amount of waste produced by saving those repaired items from the landfill.

Years ago, I took an online course on mountains, and one fact that stuck with me from it was about how people in the USA accidentally polluted the water in New York City by cutting down trees.
It was the 1800s, and the trees in the Catskill Mountains were cut down to accommodate growing populations, and as a result, the water quality for New Yorkers deteriorated rapidly. Yes, the agriculture pollution and sewage did play a part, but the trees were decided to be such a big problem, that they decided something had to be done.
So, they purchased land, and planted 18000 trees to restore the natural ecosystem.
How does this water-cleaning work? With watersheds.
“Watershed: an area of high ground from which water flows down to a river” | Cambridge Dictionary
Imagine it is raining in a forest. Droplets hit the ground, and —thanks to the vegetation which slows runoff — it is absorbed into the soil like a sponge. As the water moves through the soil, microbes are actively removing harmful pollutants, silt is filtered, and plants removing fertilizers.
Some of the water will end up in our lakes and streams, but will be much cleaner than when it started.
"The ability of forests to aid in the filtration of water doesn’t only provide benefits to our health and the health of an ecosystem, but also to our pocketbooks. Forest cover has been directly linked to drinking water treatment costs, so the more forest in a source water watershed, the lower the cost to treat that water. Forests provide these benefits by filtering sediments and other pollutants from the water in the soil before it reaches a water source, such as a stream, lake or river." | American Forests
Since this intake and outtake of water is gradual, removal of these forests can even to lead to a higher chance of both droughts and floods.

Have you heard of the beautiful living root bridges in Meghalaya, India? Their construction is a lesson in patience as the roots are gradually encouraged to grow in the supportive shape. They need regular care, but grow stronger with age.
“Once a bamboo structure has been stretched across the river, the roots of the tree, usually the rubber tree (Ficus elastica), are teased and manipulated to become entwined with the bamboo until it becomes a strong mesh. The roots are allowed to grow gradually and strengthen over time. In the initial stages, only about 15-20 people can cross the bridge in a day. Much later, it can be as many as 50 or more, although it can take up to two decades for a living roots bridge to be finished.” | The Guardian
Once done, the bridges can have a lifespan of several hundred years; far outliving the original creators of them.
It is unknown when this tradition started, but they were written about in 1844, so it would be far earlier than that.
I just thought people on here might find this tradition as fascinating as I do.

That quote was for the shoes. Sorry for not being clear about that. I’ll edit my post to add dividers in case that helps
I didn’t mean it as a advert (I even pointed out that more work needs to be done on efficiency), I just wanted to share an energy generation possibility that most people don’t know is a thing. I apologize that my wording came off as so bias
Edit: people were getting confused about which quote was for what, so I added dividers and titles to separate it all better. Sorry for the confusion.
Kinetic Tiles
Many years ago now, I was watching an NHK (a Japanese broadcaster) program about how kinetic energy was going to be utilized in the busiest stations in Japan. The theory was simple; as people walk over a mat, their steps would produce electricity to help power the station. In any other station it might not work, but in a station that typically has 1.57 million passengers per day, that is a lot of people power.
Since then, there have been many companies attempting to utilize kinetic energy, with the biggest company likely being "Pavegen." They have their system in certain city sidewalks, airports, and even under sports turfs.
"The downward force drives an energy-storing flywheel inside the tile, which spins to convert kinetic energy into electrical energy through electromagnetic induction. It’s like a generator — only instead of spinning a turbine with wind, water, or coal, it’s spinning a flywheel with footsteps." Grist

Kinetic Shoes
If tiles are not unique enough for you, that same tech can be used in shoes.
"The researchers say that this method can produce a lot of watts relative to the surface area of the generator, with the proof-of-concept device generating around 10 watts per square meter in early experiments. They claim that theoretical estimates indicate up to 10 kW might be possible." NewsAtlas

More work needs to be done to make kinetic energy more efficient, but there is just something fascinating to me about power generation that can fit seamlessly into our world without us noticing.
To ensure his plans were based on historic originals, Gareth purchased over 1,700 survey drawings of the Bourn Windmill in Cambridgeshire, approximated the measurements, and then reconstructed a quarter-size copy in his garden.
Gareth relied on his skills and education as a classical boat builder at the Falmouth Marine School, which also serves him at his day job repairing furniture. The windmill is built mainly of green oak and can rotate to be directed at the wind. He sewed the sails himself from a curtain he bought in a thrift store.
The mill’s generator produces 100 amps at 12 volts when spinning at its optimum speed.

Not sure! It does not say on their website. Here's the info they have:
Partners with Sun invented and patented the first Industrial Solar Oven. The Solar Oven has been successfully tested and launched in the year 2022. The Solar Oven cuts up to 80% of the bakery’s fuel bill and improves its production efficiency, increasing its profits and savings. The Solar Oven is embedded with IoT technology to optimize energy consumption and production processes

Sorry! I have dyscalculia, so I'll admit I didn't try to analyze the numbers at all. I can delete the post
