Transportation systems, as we know them today, will simply not sustain the worlds’ growing population. John Sterman says we need to see transportation in its complexity, and expect that our planning efforts will have totally unintended, unexpected “rebound” effects.
“There is just no question, the current transportation model does not scale. It isn't going to happen — because everybody wants to be as rich as we are, and we all want to be richer than we are today.”

MIT researchers have produced carbon fibers coated in carbon nanotubes without degrading the underlying fiber's strength. The engineered fibers may be woven into composites to make stronger, lighter airplane parts.Image: Stephen Steiner
