  • TLDR; the front side is 23% efficient, and the rear side 20% efficient.

    They don’t actually give an overall efficiency but it implies a total of 43%. They compare this to typical panels also at 23% efficient, so it’s really remarkable if true. Other emerging solar tech is up to about 32% but if that could also benefit from multiple layers then total efficiency could become insane.

    Seems a little too good to be true, really, but great if so.

    Edit: Yeah, I don’t think these efficiencies can be added like that. I guess the overall efficiency will depend on how reflective the ground under the panels is, and they will extract 20% of that. Maybe that’s why they don’t give an overall rating.












  • Not to be dismissive of these deaths, but there should not be any expectation of self-drive cars being perfect, ever. The reality is that if they are safer than humans overall, then they have reached a point where we can (and should?) adopt their use. It’s not a huge surprise that there is some form of bias in the current deaths simply because biases arise in any complex, real-world systems.

    We should, and must, accept some glitches.

    But, uh, yeah Tesla may well try to delay addressing the biases if we don’t call them out, so this info is good.
