  • Would be exceptionally easy for the U.S., the renewable power potential is enormous and making E-Fuels or E-Crude is pretty damn easy. It’s not very efficient, but 0 Co2 is 0 Co2.

    But the best part is, it’s actually economically viable. Many parts around the world agreed to a Co2 Tax, making Fossile Fuels increasingly expensive - synthetic fuels, gasses, paraffines all would be exempt. And all those that want to drive 1000 Miles on one tank, do a cannonball run or tow a few tons can still do in whatever way they want…just without Co2. Hell, even the coal rollers can do just that…

    Overall however, saving democracy and the constitution should be top priority…
















  • I’m not entirely sure what you are talking about, but most backup systems are Plane based.

    GPS is mostly used for something called RNAV, however, RNAV can work without GPS. RNP approaches need GPS, but all airports (regardless how small, because without it would only be an airfield) have different approaches for both pilots and ground personnel to choose from. GPS always has the possibility to fail, for the simple fact that the US military can just turn if the civilian frequencies. GPS is more or less an addition and not a crucial system (except for GPWS - while most planes have radar altimeters, they can’t react fast enough in some cases)

    For those interested, here’s a Video where GPS gets jammed and there’s an explanation on what they do and what happens, when it gets spoofed https://www.youtube.com/watch?v=4dG_Whxzdkk
