    Incorrect. The condensation you are seeing in the air is a product of combustion. If no water was added to the air, then compressing it and decompressing it would not create a cloud or vapor trail.

    Edit: Fine. It’s mostly incorrect.

    https://en.wikipedia.org/wiki/Contrail

    Yes, the lower pressure can create a very temporary contrail, and in rare situations where the engine exhaust also cools down below freezing before it reaches ambient pressure, ice crystals can form and create a longer more visible contrails. Realistically, what you are seeing in a contrail is water vapor from combustion. Seriously, H2O and water are the largest products of combustion, and it’s like 99% of what you are seeing behind aircraft.

    If you loosely define chemtrails as “a trail of chemicals” then almost everything has chemtrails. Fuckkin ants have chemtrails, it’s how they communicate and navigate.

    Chemtrail conspiracists literally think that airplanes are full of 55 gallon drums of chemicals with the express purpose to harm or feminize the populace to prevent people from opposing the government.







  • Not sure. Toyota is a very conservative and risk-adverse automaker. My guess is that they thought it could work better in Japan, as they have less land area and more miles traveled by train. Hydrogen can kinda make sense for a service/fleet vehicle that works in a limited area and always returns to the same location at the end of the day. Hydrogen can be run through an ICE engine, or it can be used in a fuel cell to produce electricity. Plus, everyone else was doing R&D into BEVs, so doing a little into hydrogen makes sense. If you fall too far behind on BEV tech, you can just buy a competitor’s vehicle and reverse engineer it to catch up.

    I’m not a business person. Take that all with a grain of salt.

    I stopped at a stop sign and somone almost rear-ended me. Had I driven through, I would have been safe. There is no reason to stop at stop signs. Other people can stop if they choose to, but the government can’t force me to risk a rear-ending in order to protect someone else. Jesus wouldn’t let me get T-boned in an intersection, I’m covered in his blood.



  • It’s the nature of hydrogen as a fuel. It’s a gas, and has a very low power density. You can either compress it, but that requires the car carry a robust (and heavy) pressure vessel around. Plus, all the delivery infrastructure has to handle hydrogen at those crazy pressures, or you need to carry the compressor in the vehicle, which again is heavy, and slow. The other possiblity is to condense the hydrogen by cooling it. But now you need bulky insulation for the tank, plus, it will either need active cooling from the car, or your have to accept that the hydrogen will eventually get too warm and blow the tank, and then you have to vent it.

    Hydrogen doesn’t make sense at car scale.




  • Growth for the sake of growth is the mantra of the cancer cell.

    Elon has killed them at company. If when he bought into it, did a little marketing and then backed off and let qualified people design the cars and run the company, Tesla would still be a viable company. Where do they go now? The Cybertruck is a flop on the same scale as the DeLorean, the CEO is a straight up Nazi and Putin collaborator, and they can’t get rid of him or it will kill the company. The choice is either a slow death from keeping Elon, or a quick one from firing him.

    Or they can hire me. I can fix it, or at least not do any worse.



  • How harmless are we talking? I’m thinking of one that randomly “locks” the next file you try to open that was last accessed over 30 days ago. It prompts you with “File locked by last user, please enter username/email and password”

    No matter what you enter, it unlocks the file.

    Then the next time it triggers, it prompts you again, but blocks you from using the same username and password.

    Rinse and repeat while the user keeps giving you all their user names and passwords over time.
