Useful basic information
Not related to the rotary engine but supremely informative IMHO
This site is the bomb, especially for newbies (like me) looking for more or less sound, basic information regarding internal-combustion engine powered vehicles:

Mr. Chris, I found to be a very direct writer, has indeed done an extremely good job of putting the fundamentals down in a very accessible manner for all to read. This should be at the very least, information what even a remotely-enthusiastic car person should know about/made aware of.
My hats off to him and cheers (if he happens to read this)
