  • Because it will always take more energy to break the water than you will get burning the Hydrogen in Oxygen back into water - it’s basic thermodynamics.

    You will lose some energy as heat that you cannot get back*.

    You can’t power a car from a process that loses energy. Even if you use a battery to donate the lost energy, then you might as well just cut out the lossy middleman and just run off the battery or generate the Hydrogen elsewhere - which is what we currently do.

    It is better to think of Hydrogen as an energy transporter than as a fuel, as you’d need to generate the Hydrogen somewhere that has abundant energy (ideally renewable), then transport I where needed, such as a Hydrogen powered generator.

    *Interestingly the fact that all processes generate waste heat means the only theoretically 100% energy efficient process is heat generation itself, as all forms of energy eventually degrade to heat (as it is essentially the universe’s waste energy).



  • Pretty much…

    Recessive malfunctions can hide away amongst carriers for generations before manifesting any deformities, during which time they have no effect on the carrier’s survival, so there’s very little selective pressure against them.

    Dominant malfunctions which cause deformities simply can’t hide away, so have enormous selective pressure against them.

    Interestingly enough though, there are times where dominant malfunctions can survive that pressure…
    For example, having Sickle cell disorder increases your resistance to Malaria, so even though the full form is rarely passed on, the single allele form (which caused partial disorder) is passed on due to a slight positive selection pressure.


  • I’ll try to keep it relatively simple - your cells contain chromosomes that contain your genes. You usually* have two sets of every chromosome.

    These genes come in different variations/mutant forms called alleles. Most alleles function more or less the same, but some malfunctions result in deformities.

    If a malfunctioning allele results in errant gene inactivation, it is known as recessive, which means as long as your other copy works, you’re all good.

    If a malfunctioning allele results in an errant gene activation, it is known as dominant, which means if you have the allele you get the deformity regardless of if your other copy works or not.

    Fortunately for life, most malfunctioning alleles are recessive, so as long as you’ve got high genetic variance (a lot of alleles) in a population, the chance of two people meeting with the same recessive malfunction is low.

    Incest can result in a drastic decrease in genetic variation, which can result in malfunctioning alleles becoming much more prevalent than they usually would be, resulting in many more cases of recessive deformities than in the wider population.


    *For males this is not true of their sex chromosomes. Many genes present on the X chromosome are missing on the Y chromosome, which can lead to sex exclusive traits and diseases.

    For example, it is the reason why there are almost no calico/tri-colour male cats, as the genes for it are in X but not Y chromosomes.


  • Well the idea is that you’re paying for someone who is both qualified in dealing with mental health issues, and is completely unattached to your life to provide a confidential, non-judgmemtal outsider perspective on your life.

    The people who know you almost certainly can’t provide that level of support in your life, and many people need that space/perspective to help them recognise their issues, or push them towards the correct solution to resolving them.

    It’s not everybody’s cup of tea, it ain’t mine, but for those it does work for, it works well


  • The rest of the world got the right version of the man’s work

    Which is (or at least should be) “Aluminium” because that’s the internationally agreed IUPAC spelling.

    We gave up the cooler spelling of Sulfur to be consistent with IUPAC - if we can do that, then surely giving up on “-num” should be a cakewalk.


  • Except it’s not clickbait - I’ll cite Wikipedia so you can look yourself, but they’re not the same thing.

    Rose Gold is a proper alloy of Gold, made with Copper.

    Purple Gold is an “intermetalic” (which have a different molecular structure to normal alloys and thus are more brittle), and is made with Aluminium.

    Due to it’s brittleness even amongst intermetalics, it is considered hard to work with, much more so than a proper alloy like Rose Gold. The only similarity they share is their colour ranges can overlap dependent on how they’re made.
