  • 98% of hydrogen is currently made from fossil fuels.

    While it’s possible to make hydrogen from renewable electricity, you immediately lose at least 60% of your energy in the electricity to chemical to electricity conversion steps. For comparison, batteries only lose 5-10% in the round trip charging.

    Hydrogen really only makes sense in applications where batteries can’t be used, or efficiency is not relevant. So many companies have publicly announced their new hydrogen vehicles, then quietly stopped using them and started using battery electric vehicles instead.

    Hydrogen just costs too much, and the hard limit of chemical efficiency means it will never be cheaper than batteries.

    With complete transparency, a corrupt government can execute any group they want (disabled, homosexual, black, immigrant, etc).

    If everyone was completely transparent about everything, a corrupt government would not be able to form. Unfortunately there are people without empathy who will hide their actions, and use other people’s information against them.

    I can’t force a government to be completely transparent, but I can save my own life by not disclosing certain information about myself to them.

    I don’t hide my bank account and password because I’ve done something wrong or I’m afraid that people will see what I’ve spent money on. I hide my bank account and password because I’m afraid that someone will take all of my money, then I’ll starve to death.

    There are many things that should be public: laws, standards, political donations.

    Some things are beneficial when public, but are considered acceptable to be private: source code, recipes, political opinions, criminal history.

    Some things can cause significant harm if not kept private: passwords, home address, government issued id, Jewish heritage during WW2.

    “I need privacy, not because my actions are questionable, but because your judgement and intentions are.”
