Click here to view full list of my ideas on Halfbakery

Initially, I was collecting the engineering solutions, but from now on I am trying to document interesting scientific hypotheses that I came up with to explain some problematic phenomena. There, the phoenomenon itself is a problem, and the hypothesis is an idea - a potential solution to the problem. I will also include them later on.
