[Vwdiesel] More on radiator as a battery (weekend science thread)

[Libbybapa at wmconnect.com]

An op amp is a circuit that increases or decreases current until it sees a 
specific resulting current.  In other words the right one would always keep the 
voltage in the system at zero.  No need for sacrificial metals.  It would keep 
everything where it is.  No more head and block ending up in the radiator.
