  • If you are worried, a qualified medical practitioner is always more reliable than a web forum.

    Insufficient or poor quality sleep can cause problems with attention and memory, and can exacerbate existing conditions.

    Poor sleep could be caused by a medical condition (sleep apnoea), or psychological (stress). Often stress can be hard to identify, particularly if it’s long term stress.

    Again, this might not be your problem, and finding the right doctor who actually listens to you is important. Don’t be afraid to try more than 1 doctor if the first makes you uncomfortable.

















  • The problem here is round trip efficiency.

    Using a battery to store solar power is about 95% efficient. A small amount of energy is lost to heat when charging and discharging.

    Using hydrogen as energy storage is about 30% efficient. A small amount of energy is lost when making the hydrogen, but a large amount is lost when converting it back to electricity.

    Unfortunately this isn’t even a solvable problem. The fundamental limit of efficiency due hydrogen to electricity is about 50%. Physics and entropy prevent it from being any higher.

    Burning hydrogen for heat is about 100% efficient, but heat pumps (running from electricity) can be over 600% efficient. Heat pumps get the extra efficiency by moving heat rather than creating heat directly.

    If you wanted to use hydrogen from electrolysis, we would need 3 to 6 times as many solar panels than if we just used batteries.

    Hydrogen can be clean, but it’s rarely the best option.
