  1. Thank you for another great video. There's some interesting things to think about this week. Why would the ratio of "semi-heavy water" to regular water on Earth be lower than the ratio in V883 Orionis? I did a little Googling, and it sounds like Earth is unique even in the Solar System. The deuterium-to-hydrogen ratio increases as you go out from the Sun, although not in a simple linear fashion. It's higher on some of Jupiter's moons than the Oort cloud, but lower on Jupiter itself. (No doubt there's been some mixing over billions of years, with different bodies moving around.) But the deuterium percentage is consistently higher on every other water bearing body than it is on Earth. So why is Earth different? Is there some mechanism that separated out most of the deuterium that was originally there, or did Earth receive extra water with a lower of percentage of deuterium from a source other than the interstellar medium?

  2. Hi MC's Creations, it's nice to see you here. There are some companies that want to use carbon capture to make synthetic fuels. They would still add CO2 to the atmosphere when burned, but because that C02 was taken from the air to begin with they wouldn't add any extra that wasn't already there. In a world with higher carbon taxes than we have now, this could be a way to fuel vehicles like planes that can't easily accommodate heavy batteries. The problem with making things from captured carbon like fuel and carbon fiber is that it adds extra steps to the production process, and that adds costs. The carbon capture derived substances would cost more than the same substances made from cheaper carbon sources like mining waste.

  3.  @Thomas-gk42  To you as well. :) This has been a fun discussion.

  4. Sorry, I don't understand. Is that a mechanism for removing deuterium?

  5.  @Thomas-gk42  That makes a lot of sense! I wonder if gravity could have sorted out the deuterium in the primordial cloud the Solar System formed from. Maybe fractionalization moved it to the outer edges over time?
