By using these electromagnetic waves, spacecraft employing this technology would need no engine or fuel-the most prohibitive expenses of space missions. Benford, a NASA consultant for the Mars Outpost project, is testing the sail prototype in collaboration with Jet Propulsion Laboratory researchers. He also is an award-winning science fiction author of 25 books. In their forthcoming book, Travel by Design, Marlon Boarnet, professor of urban and regional planning , and UCLA colleague Randall Crane offer the first systematic assessment of attempts to solve transportation problems through neighborhood design. Boarnet and Crane show there is a good deal of complexity and ambiguity in the link between neighborhood design and driving behavior.
Specific policies targeting congestion or auto emissions can be more effective, the authors claim.
They also recommend basing land use and transportation policies on comprehensive analysis of the relationship among urban form, travel and transportation problems.
