These slides introduce a course that helps students understand when new technologies become economically feasible. It does this by focusing on technologies that are experiencing rapid improvements. These technologies (and systems composed from them) are more likely to become economically feasible for a growing number of applications than are technologies with less rapid rates of improvement. It also helps students understand the reasons for these rapid rates of improvement and thus the types of technologies for which we can expect rapid rates of improvement. While many analyses of new technologies focus on demand and production, these slides show how other technical changes impact more directly on improvements. these technical changes include new materials and scaling.
