  1. Solar Dreams: a history of solar energy (1878 - 2025)

    Feedback is always welcome, and doesn't come off as rude at all. Most of the timeline is made as it goes (with some events I have thought from the beginning), but in this timeline sun irradiated areas will have competitive advantages that will make them more valuable for exploitation. Again...
  2. Solar Dreams: a history of solar energy (1878 - 2025)

    The machine described is based on this article in Low Tech Magazine. Indeed, that site is an inspiration for a lot of elements in this TL, and is one of my favourite parts of the internet. As for Poul la Cour, he is similar to Augustin Mouchot in that both advocated for alternative energies...
  3. Solar Dreams: a history of solar energy (1878 - 2025)

    Yup. That's the long and short of it. And Africa will become a lot more comfortable for colonizers once Stirling coolers become mainstream. Africa will suffer extensive changes in this timeline. It's more expensive, but the energy savings it generates is enough to quickly offset the costs...

    Threadmarks: Annex 1890: A Cold Winter II

    Askov, Denmark January, 1890 Poul la Cour had conflicting feelings over his latest development. It wasn't the grand invention that would change the world, but rather another helpful but unremarkable part of a whole. But it had the potential to be profitable. And, as his correspondence with...
  5. Solar Dreams: a history of solar energy (1878 - 2025)

    These are small stories designed to be a glimpse into the world's development beyond the main focus of politics, societal change and technical evolution related to Solar energy. Speaking of which, next update will cover what Poul La Cour is doing in Denmark.
  6. Earlier Modern Adoption of Solar Power?

    Solar generation becomes viable in the 1860s with the work of Augustin Mouchot. Mouchot's devices used concentrated solar heat, which would be more practical in a pre-electrified world, and were economically viable in France before a trade deal with Britain removed interest in the development of...

    If it can exploit its mineral wealth as Chile is planning to do, Australia would have most of the advantages Atacama has.

    Threadmarks: Annex 1890: A Cold Winter I

    Boston, Massachusetts January, 1890 Abelino López-Tikuña tried to give the peace to his fellow churchgoers, knowing full well that only a few would give it back to him. His skin and his factions were different. They were also different in Bolivia, but back in his country he at least had a...
  9. Solar Dreams: a history of solar energy (1878 - 2025)

    It depends on the type of solar collector. Stirling-based devices will have problem in sandy deserts, but direct heat devices are basically a mirror and a pipe, so a regular wash is enough to solve most problems. DC motors and lighting (incandescent and arc lights), if I remember correctly...
  10. Solar Dreams: a history of solar energy (1878 - 2025)

    Pretty much any desert near the tropics will be an ideal place for solar energy. Combined with the "short legs" energy distribution has at this point (since AC transmission is in its early stages, and the power grid won't be a thing for decades), it will probably lead to a very different...
  11. Solar Dreams: a history of solar energy (1878 - 2025)

    Cheap generation of high temperatures will result in more advanced electronics compared to OTL, but without an understanding of the Photoelectric Effect and the structure of the atom, transistors as we know them won't be possible. The same applies for modern photovoltaic cells (although there...

    Threadmarks: 18: Accretion

    February 1889 Syracuse, Sicily Klaus kissed his wife as he rose from the bed. She smiled, and in an unconscious act reached for him, to stay together a few more minutes. But he had to reject her, had to switch his mind back to the scholar and researcher, not the loving husband. One by one, the...
  13. AHC: A World War crisis for every nation

    Chile: The 1891 Baltimore Crisis results in a war between Chile and the US, with UK intervening in Chile's favour to consolidate its control of the nitrate-producing regions. Things escalate.
  14. Solar Dreams: a history of solar energy (1878 - 2025)

    The size is the same as below, it's just that finding images of 1880s Egypt suitable for photo manipulation doesn't leave me with many options to place the devices. Especially since they have to be aligned with the sun. Thus the awkward angles.
  15. Solar Dreams: a history of solar energy (1878 - 2025)

    For reference, this is the size of one section of the solar boiler. It has a concentrating mirror with an area of 18 M2, and has a modular design which docks several sections for additional power. One by itself is only useable for lightweight tasks.

    Threadmarks: Visual Document II: Cottrell Solar Boilers in Egypt ca. 1890

    Cottrell Solar Boilers topping a building on an industrial area of Alexandria. This design was a refinement of the Mouchot-Puig boiler whose manufacturing rights were acquired by the British Empire in the aftermath of the Tarapacá Massacre. Mobile modification of a Cottrel Solar Boiler for...

    I can see some experimental uses of solar collectors as weapons in Subsaharian Africa, albeit with limited results.
  18. Solar Dreams: a history of solar energy (1878 - 2025)

    It's an issue of diminishing returns. The "thermal buffer" approach relies on the square-cube law to retard thermal equilibrium, as the large mass has a comparatively smaller area to exchange heat. Applying a thermal coat would be inefficient. The coat works by insulating the hot exterior from...
  19. Solar Dreams: a history of solar energy (1878 - 2025)

    The thing is that solar energy - specially the kind developed ITL - can't be practically weaponized: - It's impossible to use half of the time. - It requires a significant infrastructure that can't be moved easily - It isn't dense enough to power vehicles. So no solar powered ships or trains...
  20. Solar Dreams: a history of solar energy (1878 - 2025)

    Not lasers, as those work on an entirely different principle than Concentrated Solar Heat. I can't find the video, but there was a laboratory on Youtube in which concentrated solar heat acted like a lightsaber, vaporizing small amounts of metal. Combining that with something like a Jacquard...
