  • Could you go into detail what you mean with the last sentence? Example: Should I assume someone else can not walk somewhere when they ask me for directions after walking to me? Surely that is not what you mean, but all the examples I can come up with in this moment are about as absurd as that. I can not see how always assuming others might have some (relevant to the situation) disability would help me interact with them instead of doing the exact opposite.










  • Nobody will remove water from ambient air in relevant amounts. Roughly 0.5 % of air is water vapor, a total of something like 10’000 km³ liquid water. This is replaced (residence time) about once every 10 days, so roughly 1’000 km³ daily.

    Say we extract 10 km³ (10’000’000 m³) daily, enough for roughly 10 million people (including all industry, zero recycling of the water etc.). By that time you deal with 1 % of earths atmosphere every day. May I remind everyone how absurdly costly in any conceivable way that would be? You would rather lay a few pipes and purify sea water at a tiny(!) fraction of the cost.






  • Are we missing some zeros here? So one to a few hours of testing, that is it? So I assume the sensors simply failed completely after that, why else would they not test it longer or withhold the results? Quote:

    Researchers tested them at different bending speeds:

    838.9 mV at 100 bends/hour 856.7 mV at 200 bends/hour 852.6 mV at 400 bends/hour

    Even after hundreds of cycles, the signal stayed strong, proving these sensors can handle repetitive movement without breaking down.

    This kind of reliability is huge for prosthetic limbs, fitness trackers, and robotic arms, where precision and durability are non-negotiable.
