The patent getting snatched up by cosmetics and then re-discovered almost 50 years later makes me wonder how many cool advancements have been lost to industries that couldn't find any value from them.
MDMA was originally patented 1912/1914 by Merck, but wasn't really applied for human usage until Dr Shulgin was working with it over 50 years later.
Anybody know how it's possible that adding an additional substance to a chemical compound could decrease it's weight? Or does it just mean that less volatility means it can be transported in lighter containers?

Apparently one can make dry water with a blender - mix fine silica powder and water in a 1:19 ratio (by mass) and put it in a blender for a few minutes. I'm not going to risk my blender to try it, so who's first?
Blenders can be replaced. I would worry more about silicosis. https://en.wikipedia.org/wiki/Silicosis
Earlier quoted context omitted.
Sounds interesting - Do you have a link for that, or if you've got time could you explain?
There's a lot of literature on this; Wikipedia has a decent starting point: https://en.wikipedia.org/wiki/Carbon_sequestration#Geologica... TL;DR: if you compress CO2 to above 73 bar, it becomes supercritical fluid, which has a density almost like water and which does not mix with water. If we inject this fluid into underground saline aquifers, we can trap it indefinitely. Basically exactly the reverse of producing o…
"It can be used as a medium for volatile compounds, as materials stored within the dry water can be reduced to powder and stabilized – reducing not only the volatility of the substance, but also its weight for transport."

In many fields there are waves with the patent expiration cycle, for instance 3D printing or VR. As the patents expire there is a flurry of new research, everyone obtains new patents and it becomes impossible to create viable products again, until the patents expire and the cycle begins again.
