>running out of helium
Hmmm 🤔

  Feel like we could probably just make more once we get fusion going. We have functionally infinite hydrogen.

  @BowsacNoodle Too many satellites depleting Helium 😜

  @BowsacNoodle We only really get it from radioactive decay, as it's so light that when it escapes into the atmosphere, it soon escapes into space pretty much.
  
  Semi-recently, more reservoirs of it were found, but those will run out eventually.

  I forgot how insanely efficient fusion is. Well that's something...

  COMMERCIALLY VIABLE COLD FUSION IS, AFTER ALL, JUST A COUPLE DECADES AWAY

  @nugger @BowsacNoodle Any reasonable fraction of global energy from fusion plants would add well under 1% to current helium venting to the atmosphere.

  I am more optimistic than I should be about certain things. It's because I try not to be too much of a chicken little bit I do see the cracks and missing bricks in every aspect of our society's foundation.

  So it just floats to the top of the atmosphere and "adios"?

  @BowsacNoodle Pretty much, the least dense gases go to where the density is least and the outermost layers of the atmosphere are vulnerable to being pushed into space via numerous processes: https://en.wikipedia.org/wiki/Atmospheric_escape?useskin=monobook

    Atmospheric escape
    
    Atmospheric escape is the loss of planetary atmospheric gases to outer space. A number of different mechanisms can be responsible for atmospheric escape; these processes can be divided into thermal escape, non-thermal (or suprathermal) escape, and impact erosion. The relative importance of each loss process depends on the planet's escape velocity, its atmosphere composition, and its distance from its star. Escape occurs when molecular kinetic energy overcomes gravitational energy; in other words, a molecule can escape when it is moving faster than the escape velocity of its planet. Categorizing the rate of atmospheric escape in exoplanets is necessary to determining whether an atmosphere persists, and so the exoplanet's habitability and likelihood of life. Thermal escape mechanisms Thermal escape occurs if the molecular velocity due to thermal energy is sufficiently high. Thermal escape happens at all scales, from the molecular level (Jeans escape) to bulk atmospheric outflow (hydrodynamic escape). Jeans escape One classical thermal escape mechanism is Jeans escape...
