  • I think it’ll have an effect. If you think of the cross section of the piping in the condenser (radiator in the outside unit shown in photo), you have heat trying to transfer from the fluid on the inside diameter, through the pipe wall, then to the air surrounding the outer diameter.

    Heat has to flow from hot to cold, so ideally you have a gradient from hot to cold going from inside to outside.

    But suppose the sun intensely heats that pipe wall and it ends up higher than either fluid on either side of it. Now you’ve got heat flowing from the wall to both inside and outside.

    Not saying that ever happens, but every degree warmer that the pipe wall is, is a slow down in the heat transfer rate. Less of a gradient for the heat flow.






  • Veganism definitely has terrible PR. But we also have to be wary of cherry picking the extremists from a movement as representatives of the whole.

    I’d like to be 100% vegan, I’m not but I try. We started with weekday vegetarianism and went from there. Moderation is absolutely effective, IMO.

    What if bias start to grow within academic institutions?

    What if the public funding to those institutions influences which departments get more/less funding?

    I actually am asking genuinely because I would be happy to know we can improve on what we’ve got.
