Energy Returned over Energy Invested: Time Delay and Spatial Separation for ERoEI

http://eroei.blogspot.com/2012/12/time-delay-and-spacial-separation-in.html

The importance of the ratio of Energy Returned over Energy Invested cannot be overstated; however, different researchers have included different items in the energy invested term. This may be satisfactory depending upon the use to which the concept is to placed; but, only the method recommended on this blog results in a ratio that can be used to determine sustainability of the technology*.

Railroad Modeling, Track Plans, and Model Railroad Photography: My contribution to manual turnout control with live frog

http://modrr.blogspot.com/2015/04/my-contribution-to-manual-turnout.html

Here is where I post whatever I have been working on. These days, it is the Free-Mo N layout at the Northwest Crossing Operating Model Railroad Club. Wednesday, April 8, 2015. My contribution to manual turnout control with live frog. The PVC inserts protect the control rod during transport and while on exhibit. If scale model dummy switch stands in N scale are available, one might figure out where to put them so that they look right. Any suggestions? Subscribe to: Post Comments (Atom).
