I was recently contacted by the inventor of a "revolutionary" airport layout:
Earth Wise International - Starrport
The basic idea is that the runways are built on inclines (4% to 5% grade) so that all takeoffs are downhill and landings are uphill. The terminal is located underneath the peak of the pyramid structure. The inventor makes some pretty dramatic claims about the fuel saved by this design.
Is he missing something obvious, or does this seem like a plausible concept to those who know something about aviation?
