  • Speculation on my part:

    Patriot stocks may have been really reduced - by defending Israel during Netanyahu’s adventure against Iran (it could have been smarter to tell Netanyahu not to start).

    There is no reason to think that stocks of other weapons (e.g. air to ground missiles, glide bomb units for F-16) have suddenly gone really low. In fact, there is probably a f**kton of them.

    Consequently, I suspect that Trump and Putin have made a deal they failed to disclose: Putin promised to refrain from helping Iran (it was an easy promise, he was really low on supplies). Trump promised in return to refrain from helping Ukraine, which he could have easily helped. At best, he got conned, at worst he got to do what he already wanted.

    I would advise journalists to ask around: “has the US DoD been ordered to alter criteria for determining what is sufficient supply?” If yes, we’re looking at an excuse. If no, we’re looking at inability.

    Both are bad, but inability can be corrected with honest admission and action, Ukraine has a bit of money from other allies to actually buy some US weapons, although they are rushing to make more domestically.

    If it’s not inability but an undercarpet deal, then corrections are bit harder to achieve.




  • Hard to tell. Definitely not where I live (Estonia) since local planning bureaucrats seem to have a fairly strict understanding of “how you are supposed to live”. What follows is an imaginary conversation with planning officials over years:

    • “why do you ask for a building permit, you’ve got to get a road first”

    • “we want you to pay for the road, paving it, running road lighting along it, etc, please invest several hundred thousand into getting that road”

    • “so, to bypass our demands, you built an agricultural building, please don’t live there, at least not publicly”

    • “you want to install solar panels, there’s a permit for that”

    • “so, to bypass our demands, you installed movable solar panels and a solar fence, we are severely concerned about it and consider taking action, but won’t”

    • “after years, out of sheer bordedom, we are intending to privatize your access way and attach pieces of it to other plots of land”

    • “we can’t take public ownership of it, as that could obligate us to build a road there, and we don’t really understand why you wouldn’t want to force us to”

    • “oh, you spoiled part of our plan by requesting a power grid connection to be built along that path of land, now we’re kind of stuck with it, but hey, let’s try to obstruct getting the grid connection built”

    • “let’s have doubts about why a power grid connection is needed, as the buidling it might supply isn’t properly registered”

    • “oh, you have written that you need a power grid connection for a vehicle charging point and those have really low planning requirements, damn convenient to you, in fact you might get the connection built indeed”


  • Same question. :) The OP seems to have forgotten to post it.

    What I can tell by heart: MorningStar is an established brand and they’re fairly well trusted - they’ve been selling charge controllers and inverters for at least a decade. They might be a bit costly, but there’s support and it’s likely to work. :)

    Myself, I haven’t had the chance to look at their products up close.













  • It’s a pretty neat system:

    • can be set up anywhere
    • can supply high grade heat (process heat, not mere space heating heat)

    However, heat stores are subject to scaling laws which don’t favour sand on the large scale, at least unless it’s underground (and then you have to keep groundwater out to avoid vaporizing it). Large thermal stores benefit from storing heat in water, and placing the water deep underground, so the boiling point rises. If local rock has low thermal conductivity, even better.

    For comparison Helsinki (.fi) has a 10 GWh underground thermal store. Where I live, Tallinn (.ee) will soon get a 1 GWh surface thermal store. And Vantaa (.fi) will soon complete a whopping 90 GWh thermal store that’s located 100 m underground, so their water will boil at 140 C instead of the usual 100 C. Boiling points up to 300 C are attainable in practise, then the curve starts leveling out.
