They cannot back feed when there is no grid power, yes. But they cannot differ between power used inside the house or outside the house. They can and will definitely push power back out to the grid as long as they detect grid power from other sources.
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.
How is it nonsense?
The EU law is that the reject all should be exactly as easy as the accept all button. 1 extra click, however minor of an inconvenience it is, is extra effort. And therefore strictly speaking in violation of the law.
Nothing will ever happen but it’s valid criticism.
Well you say that but their pit wall on Friday said otherwise 
But that is an easily solved problem. Take the design of the James Webb, substitute the super cooled infrared camera and replace it with a superconducting magnet setup. Fly this setup to L1 of mars and start global warming.
I didn’t come up with that. Someone at NASA did. Years ago: https://astrobiology.nasa.gov/news/how-to-give-mars-an-atmosphere-maybe/
OOP not just inheritance. Object oriented programming starts with structuring things in objects, like the name suggests. It quickly has a place in anything more then a few hundred lines of code.
