      Why isn’t pipeline hack an act of war?

    It might be an act of war but if you don’t know who did it or have an effective way to retaliate then it is difficult to respond.  If there were no cryptocurrencies then it would be more difficult to send an untraceable payment.  Perhaps that would stop these attacks.  It would take a lot of Google gift cards to make five million dollars.

    As someone who has worked on control systems for major oil companies it is difficult for me to believe that Colonial was hacked so easily.  Where I have worked the administrative systems were totally separate from the control system functions, only those that passed special background checks, passed special courses, had totally separate computers totally dedicated only to control systems, and had the proper two factor authentication hardware card could even log on locally to the process control systems.  And then EVERY control system was automatically checked at least every 24 hours to see if any unauthorized changes were made.  Every control system could operate independently from every other control system (perhaps not quite so efficiently) because one could never know when there would be some type of communication failure, mechanical failure, or electrical failure in a local setting would occur.

    An inside job hack would be possible but would be caught within 24 hours unless it was done at the very top levels of the engineering organization.  Colonial must have had antiquated procedures, hardware, and software.

      Seeking Recommendations for Water Pump that can work in Reverse as a Generator

    Induction motors can generate electricity by turning the rotor faster than the synchronous speed.  The problem that you will have (besides some wiring issues) is that your pump is not designed to be efficient when run in reverse and probably is very efficient even now. I would recommend buying a micro pelton turbine and putting a bypass around the pump.

    I don’t know anything about this particular one because I have only worked on a utility scale (like PG&E Helm Pumped Storage) systems but a pumped storage setup is cheaper than a huge lithium battery. Do a web search for other pelton wheels.  They are usually sized according to the head and flow available (which determines the total output). https://www.amazon.com/QIZHI-Generator-Household-Lighting-Electric/dp/B081DY3QB5/ref=asc_df_B081DY3QB5/?tag=hyprod-20&linkCode=df0&hvadid=416796348214&hvpos=&hvnetw=g&hvrand=403210874621481305&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9031722&hvtargid=pla-887737022098&psc=1&tag=&ref=&adgrpid=93124985239&hvpone=&hvptwo=&hvadid=416796348214&hvpos=&hvnetw=g&hvrand=403210874621481305&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9031722&hvtargid=pla-887737022098
