I like the idea of a wicker basket coffin with natural-fiber clothes…and an added sword just to confuse future archaeologists •ˋᴗˊ•

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.

Also, I’ve seen tutorials for 3D printing on Instructables, and people sometimes give download files in the instructions.

This one doesn’t list all of them, but it has some: https://www.repaircafe.org/en/visit/

This site might help with planning!

It looks like there are some! https://www.repaircafe.org/en/visit/

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

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

Very true!

There’s actually several problems with most hydro dams that sadly is often completely ignored due to it being “green energy.” For example:

• Disrupting Fish Migrations. The dams can act like walls, stopping annual fish migrations. Though this is sometimes minimized using fish-ladders, often many other aquatic species that can’t use the ladders are ignored.
• Displacing people and wildlife. For example, Lake Minnewanka in Alberta, Canada, has an underwater town that was flooded for a hydro-dam. The spot was also of importance to the indigenous people of the area, as it was seen to be connected to the spirit world.
• Polluting the Water. By causing higher levels of sediment and algae in the reservoirs. This is called “eutrophication.”
• Hurting or Killing Wildlife. The released water is often cold and low in oxygen, which can shock and even kill wildlife downstream.
• Water-Depletion. Reservoirs can cause water-depletion for an area, since still water evaporates faster than the water in a moving river, and the plants consume water to work.

That’s why I don’t always classify hydro as actually being green energy. There’s hope in small-scale turbines making a comeback in a fish-friendly style https://youtu.be/KEsrAmM07fs , as well as updated takes on tidal energy, such as the wave swing. https://youtu.be/mxesgXdw0Zw
