  • I’m sorry. How do you expect a jet flying to get even close enough to a satellite to accelerate a missile to it?

    Highest ever flow fixed wing “aircraft” is SpaceShipOne with rocket engines. Well above what a typical fighter jet might do: 112km height at 910m/s And a typical rocket will go what? Mach 2 or 3? So let’s say Mach 4 at 112 km, which is 1096 m/s

    A typical Starlink orbit is either around 340km height or more typical 550km at either 7726 m/s or 7613 m/s at the different heights.

    That gives a minimum distance traveled of at least 228km and a speed gap of 6630 m/s or 23868 km/h that the missile still needs to close.

    There are probably ways that Brazil could try and destroy satellites if they want to. But launching missiles from (rocket powered) jets definitely isn’t one of them.



  • There are inverters that support battery backup, recharging from solar and grid power that are supposed to go between your grid tie-in and the rest of your house. Quite a ways more expensive, but the battery capacity is probably relatively cheap compared to UPS power and is essentially a backup for your entire house.

    The one I read about a while ago was a Growatt that is basically an all in one box. Can provide power from batteries, recharge from solar or grid power, feed back excess solar power to the grid, etc, you name it. And I can imagine other brands producing the same solution.

    I’m lucky enough to live in a country with almost no power cuts though. I think we have at most 1 a year for max 10 minutes. So can’t say I have any experience with it myself.


  • The biggest red flag is probably that they claim to just be the WireMin protocol, but haven’t published any protocol specifications. In the spirit of open and unmoderated communication I would hope they would at least publish their protocol specifications, even if they won’t opensource their own client for it.
