Comment on 'Reverse Solar Panel' Generates Electricity at Night

  You’re getting downvoted for pointing out that this technology, at optimal efficiency on Earth, generates about 1/100,000 that of a solar panel. “Not very useful” is an understatement (it’s currently fucking useless). Even worse: the title saying “at night” implies a terrestrial usage and misdirects from this technology’s only potential useful application in the future once and if it becomes much better – namely on deep-space missions.

    That 1/100,000 comparison doesn’t seem right if these panels generate 1W per square meter as the parent poster said. It sounds like you’re saying regular solar panels generate 100kW per square meter but I’m pretty sure that’s orders of magnitude too high. Am I misinterpreting what you said?

      Agreed. It’s 1/100 with old panels at 1/300 with modern high performance panels, being up to 300w/m.

        Edit: solar radiation is only 1.3kw/m2

        Outside earths atmosphere. Only ~650 Watts/m^2 reach the surface of our planet.

    even if it only helped eek out 1% returns, on missions depending on an RTEG that could be years added.

    worth keeping an eye on.

  Clearly you don’t know how much longer sketchy hallways get in the dark. It’s at least a 20 fold increase.

  Could be good enough for light in dark places

  But… yes

  Generally not enough. But maybe with more work they could become better
