Calculation of a Metric Score
Following questions are drawn from OSE Specifications and is used to determine how well the Steam Engine product meets OSE specs. There are no real guidelines on how to use these questions. Given that there are 42 questions and a max score of 42, we assume that each question is awarded one point. In those cases where partial results are present, a score of 0.5 is awarded, leading to the possible metric score as a decimal number.
Economic Significance
01. Is it relevant for meeting the material needs of humans?
1pt - Yes, the steam engine can be used to reduce human labor and store energy for later use.
Distributive Economics
02. Does the economic model distribute economic power?
0pt - An economic model hasn't been defined yet.
03. Does it promote community and global resilience?
1pt - Yes, local power generation is essential to local resilience.
Systems Design
04. Does it consider the complete human and natural ecosystem?
.5pt - Some is done, but others (like exhaust steam and oil) haven't been considered yet.
