Can we trust them to enough? If they have a medical emergency (which is quite probable, old people are in risk of all kinds of trouble, even before the harsh environment of spaceships), will the whole mission fail?

We generally have selected the most vigorous military personnel to participate in these types of missions, using old volunteers would be quite a change.

I agree. And how all of our meager steps towards trying to learn the pre-requisites of sustainable colonies (eg. closed cycle ecology) have failed miserably. For example Biosphere program (https://en.wikipedia.org/wiki/Biosphere_2 ).

And the only working ecological system we can study is being destroyed by humanity and capital on record pace.

The energy balance just does not work with current agricultural paradigm. For example, plowing is really energy intensive and electric tractors just can't carry the required amount of batteries. Too heavy tractors compact the earth and sink in bad weather conditions.

For electrification to really proceed in ag, we need a revolution in the paradigm, something that removes most of the energy heavy processes.

This can be a bit of a class thing. If one has enough money/capital/savings to weather the unemployment, why panic? And if one has been raised in environment where there never are such buffers, panic is the default answer.

You are correct. Some devices expose local API's, most have walled garden cloud API's

Before buying a device, it is a good idea to check if there are open source adapters for it for Home Assistant, those usually show if it can be controlled easily and preferably without cloud.

This is not taking in to account the fossil fuel usage for growing wood, transporting it and processing it to pellets.

Biofuels rarely make sense, unless we can get the biomass as a side-flow from some other process. And that kind of flows are quite limited compared to our energy needs.

I use [pi-oven](https://github.com/keichi/pi-oven) for my raspberry images. Not perfect, but kind of works and removes a lot of hassle for the provisioning.

Could not quickly find out from the project page an example on how to bake rpi images with mkosi, but the descriptions do point towards somewhat similar use case :shrug:

In Finland honey is rarely pasteurized. It is seen as a quality defect if honey is heated after extraction from the hive. Heating is thought to destroy some of the beneficial compounds in honey.

Similarly one should not put honey to too hot tea if one wants the benefits instead of just sugar.

I enjoyed the The Revolutions podcast from him, but was very confused when I returned to it and new episodes were clearly fiction. I would have preferred a separate podcast instead of using the same feed for history/non-fiction and then changing to fiction midway.
