Separating Oxygen And Metals From Lunar Regolith
This looks like an interesting new method. I wonder how much it needs in reagents, and if they can be recycled?
Frequent-Flyer Programs
Are they coming to an end?
I hope American doesn’t follow suit; I’ve got a lot of miles there.
Male Infertility
Caused by vegetable oils?
Not a problem for me at this stage of my life, but there are lots of reasons to avoid vegetable oils.
Young Socialists And Communists
Thoughts on their ignorant brutality.
Cartilage
Humans may possess some ability to regrow it. Doesn’t look like it will help that much for knees and hips, though. But you never know what they’ll find next. Fortunately, I’ve never had any joint problems, yet.
