  • Everyone likes to believe they’re thinking independently.

    Can you elaborate on that claim?

    I exercise some critical analysis, but for the most part I just have trust in human ambition. For example: the reason I believe human CO2 emissions are driving climate change is not because I’ve looked at the evidence and evaluated it for myself.

    The reason I believe that human CO2 emissions are driving climate change is: that seems to be the consensus of people that have worked hard to impartially develop expertise and gather data to understand climate science.

    There are two important systems at play

    1: Scientific research, which harnesses human ambition by rewarding impartial research and discoveries which overturn old assumptions/paradigms.

    2: Journalism, which harnesses human ambition by rewarding impartial reporting on various fields of human interest. (Reporting is why it seems to be the consensus of the scientific community)

    The impartiality of these systems is (has always been) under assault by capitalism (which also derives its power by harnessing human ambition) and so one must, to an increasing degree, evaluate the appropriate level of personal mental effort to allocate to identifying biases in the reporting.












  • Interesting video, thanks for tabulating the data

    I’m surprised he is measuring with the fan so close to the ground, with the electronics obstructing the fan downwash, with the anemometer so close to the fan, with the anemometer so close to the edge of the fan, and with the anemometer so irrepeatably placed…

    I don’t think he has accurately measured the efficiency of the induction motor (no load -> stock blades @ 1 m/s is a power change of 10.5 induction and 19.3 for bldc). He is pretty casual in his dismissal of the cost premium of bldc motors too.
