This is a new and improved method of computing ERoEI so as to determine sustainability of a community if it is equal to or greater than 1.0 provided there is no growth in the population or in the economy.

Structure The Mark I economy had only one economic requirement, namely, that each person had to eat one potato per day or die. This was useful to show that one man's wealth can mean another man's or many men's death. The Mark II economy had four or five economic sectors and was useful to demonstrate the use of E/GDP data to convert money to energy...

In this paper I determine how much of the US energy budget should be charged to market overhead. The current statistics have been adjusted to account for the large amount of what formerly was our GDP now takes place abroad.

The Apollo Alliance Ten-Point Plan (http://www.apolloalliance.org/) is a good example of conservation within capitalism. Inasmuch as the lavish expenditure of energy is the prima facie cause of the national and world crisis associated with Peak Oil, it is difficult to see how conservation could possibly be a bad idea. Capitalism, however, demands e...

The Mark II Economy provides a computational laboratory in which the energy analyst can perform experiments on a simplified economy that replicates many of the important features of a real economy. The Mark II Economy is simple but not very simple. The governing equations are troublesome enough that mathematical analysis might be replaced by numeri...

If any written work described in this internet paper has been published, it has been a mistake. Whereas internet publications do not have the impact they should, as human beings do not seem to take anything seriously if they haven't paid for it in money or work of acquisition, peer-reviewed publications deserve our deepest contempt. Please see "On...

Homotopy continuation methods have been used by the authors and others to solve difficult chemical engineering flowsheeting and design problems involving the solution of simultaneous nonlinear equations. Such methods can fail when: (1) the homotopy path, which one follows from the solution of a simple problem to the solution of the original (diffic...

Globally convergent homotopy continuation methods have been used successfully to find multiple solutions to systems of nonlinear equations used to model multicomponent, multistage separation processes. However, the solutions were achieved by using a multitude of different starting points. This paper describes a procedure for finding all or some sol...

Multiple steady-state solutions for three different types of interlinked separation systems have been discovered by using a computer simulation program that applies a differential arc-length homotopy continuation technique for solving the large sets of rigorous nonlinear modeling equations. The multiple solutions were found from multiple starting p...

Second-semester freshmen, after one and one half semesters of computer fundamentals, word processing, computer graphics, numerical methods, and Fortran and Basic programming, produced a preliminary design for an ethylene oxide plant using computer simulation modules provided by their instructor. The final design report included converged heat and m...
