The missing element in our sustainable energy strategy is a renewable source of thermal energy. Geothermal energy produces heat, but its potential is limited to regions that have volcanoes. Biomass is another option, but it faces many problems. If we were to try to provide an important share of heat demand by burning biomass, we would quickly come up against the limits of what the planet can produce. There is only one source of heat energy left, and it is a powerful and inexhaustible one: solar energy. We tend to see solar energy as yet another way to generate electricity, using photovoltaic panels or solar thermal power plants. But solar energy can also be applied directly, without the intermediate step of generating electricity. Basically, harvesting direct solar energy can happen in two ways: by means of water-based flat plate collectors or evacuated tube collectors, which collect solar radiation from all directions and can reach temperatures of 120 °C (248 °F), and by means of solar concentrator collectors, which track the sun, concentrate its radiation, and can generate much higher temperatures. These can be parabolic trough systems, linear concentrating Fresnel collectors, parabolic dish systems or solar power towers. Almost all of these technologies were developed at the turn of the 20th century.

A solar power plant that generates mostly at night?

Solar–heated steam plants are not fashionable, but a point greatly in their favor is that they can (to an extent) be made controllable. This saves a great deal of trouble and cost in storage and grid–stability measures and so on.

One reason they are not in fashion is that the funding mechanisms used for PV and wind projects (which are recondite, and frankly raise some real questions when examined closely) don’t really mesh well with a multi–year construction period, followed by a fairly large amount of power coming on the line all at once. This is also part of the reason for the interest in “small modular” nuclear power units, although every time you look, the definition of “small” has crept up again. Currently units of 300 MW, almost three times the output of Crescent Dunes, are being described as SMRs, which really strains credulity.

The account of the “teething troubles” at Crescent Dunes is instructive. All steam plants seem to suffer from them. The extreme quality standards enforced in the nuclear industry typically (although not always) keep these to a minimum ― for instance, the improper welding practices which caused trouble with the replacement hot–salt tank at Crescent Dunes would almost certainly have been caught long before the tank was put in service, if they happened at all.

As Augustin Shevchik of Czechoslovakia put it at the 1955 Geneva Conference, renewable energy “will always require voluminous equipment. The problems of utilizing nuclear power, on the contrary, are problems of high–quality equipment.”

Solarpunk, if it was built by dieselpunks. The world we might have had if we hadn't struck oil and instead ran down our coal supplies in the mid 20th century.

Playing around with "solarpunk without photovoltaics".

Nearly all domestic energy use is to produce heat. Heating and hot water of course, but appliances as well mostly turn electricity to heat -- washers, dryers, dishwashers etc. Rather than do some convulated system where we generate electricity and then use a heat pump to turn it to heat, we could just collect the heat directly and use that.

Heat is fairly easy to store. Insulate a tank of rock or water and you're set. Far less resource intensive than batteries, with a system that can be maintained by local mechanics and built out of scrap. Community self reliance, rather than dependence on globocorps with long supply chains.

Cheap heat might favour communal areas. You can cook food with 60-80c heat (sous vide), but installing such systems for individual homes might not be worth it. For a cafeteria however... Same goes for boiling vessels for hot drinks. A heat pump based system to produce near boiling water would make little sense in a home, but if it's shared between a few hundred people it might.

By focusing so much on electricity production, we've missed what we need the electricity *for*.

So in the middle ages the function of fortifications was to provide a base of operations for the land-owner class to secure their (comparatively) highly mobile military assets (as well as sometimes their working class population when under threat) from invading armies that would attempt to occupy the countryside that supports their whole regime. The fiefdom is large enough that it's impractical to have a defensive perimeter so having a safe place to emerge from in superior force or hide in when you don't have superior force is the move

Right?

So in a space setting there could plausibly be a very similar strategic situation, that is, highly mobile and expensive military assets and a too-large-to-encircle territory

But a castle works by being more or less impenetrable to whoever might attack it. Assaulting it is just too costly so seiges are the norm if you are trying to fight against somebody with a castle.

And THAT isn't possible in space. If you're attacking from Another Solar System or whatever you can arrive with more or less arbitrary relative velocity, piercing ANY physical defense (those made out of glowing blue Space Magic notwithstanding) is trivially easy; everyone is Mehmet the conquerer in this scenario

But unlike a castle, a space station is in constant motion, and in space, things are very very hard to see

So I propose that a space station designed for this scenario would consist more or less of a large observatory with big-ass mirror telescopes for detecting attackers before they detect you, and would otherwise be designed to Not Reflect Stuff. You can't see a thing in space unless you get light or radio or whatever bouncing off of it. (or emitting from it)

So our space castle would be absolutely covered in black spikes to scatter and absorb incoming light, like a beam stop or the microstructure of a coating like vantablack, and its entire exterior would be chilled to the maximum possible extent to reduce emitting infrared signatures. Like, whatever star is nearby would heat the stuff by radiation as usual, but they'd have to be actively running coolant into the spiky exterior to compensate for that and transporting all that heat into some interior thermal storage space which would then have to expel all that heat occasionally, presumably in a huge plume of glowing space fire

What I'm saying is that this space station would look cool as shit and is a good setting for Whatever Space Thing
