  • Lots of risks and rewards in agriculture!

    Water is the most important thing for agriculture. Theoretically we can make it out of seawater, it's just prohibitively costly for energy and money. As energy gets cheaper or our use becomes more efficient, getting water to farmland becomes more predictable and consistent.

    Soil is the next most important thing. It's depleting at a very scary rate and that NEEDS to be addressed. As soil breaks down it releases huge amounts of (unaccounted for) CO2. But building soil also draws carbon from the air - it's actually a way faster and more effective carbon sink than trees. Soil (and the infinity of microbial life it contains) has the ability to save us from climate change. It's magical stuff, one of my favourite substances. Seriously, read some pop science about soil it really is incredible.

    Crop choice and varieties chosen will shift and change. The Cavendish banana will probably die/go extinct. Other clones will probably suffer the same fate. Genetic bottlenecking of popular fruits and vegetables isn't going anywhere

    It's a remnant from a previous housemate who hot glued hundreds of bottle caps onto the table (a repurposed giant cable spool in a previous life). It works ok but then stuff falls into the gaps and it's less ok

    They're called gollies in Australia and they're a central part of the culture in rural and regional areas - partially because everyone there is over 50 years old. Arts and crafts festivals regularly hand the gold, silver and bronze to gollies in different mediums. Dolls obviously, but also paintings, tapestries, poetry, foods, songs, you name it. It is by far the unifying cultural touchstone among boomer wasps.




  • I saw an interesting thing about flywheels being a potential solution to power storage. Set them up in a near vacuum with minimal friction and they can store power for 6-8 hours. Doesn't sound like much but you usually only need them at night time so that's plenty.

    Pumped water can work but requires the correct geography. Molten salts works quite well too with fewer drawbacks.

    Are there simple environmentally friendly batteries that don't require things like lithium? Seems like weight and size aren't an issue for grid-connected battery storage
