So I want thinking about breathing last night, seems like humans do it, plants do it, but nothing man-made (i.e. machines) do it. Plants and humans complement themselves very well by producing what each other uses, but I think most of the air is still nitrogen. So, if we could build a filter that would separate nitrogen from the air, we could have cars that run on nitrogen in much the same way they use nitro boosts for racing. Then ideally the output would be oxygen and carbon dioxide, so that everyone would be happy! ;)
Also had a nice flying dream last night, flying down the hall of someone's building after doing delivery (even though I haven't worked there in almost 6 months). I knew it was the wrong floor,and something was wrong with my eyes as I flew (my right eye was going out of focus and being crossed, causing me to steering to the left). Something about how pilots' main requirement is 20/20 vision.
