commuting planning in European situation is quite at variance with USA. Majority of urban dwelling units are in walkable distance from public transport systems.

Technology change takes decades from laboratory to pilot to commercial scale entry.

Thank you for introducing the concept of maglev. Interesting, however some of the key challenges would be
1. Scrapping the existing infra in lieu of expensive maglev technology. The cost per km is still in the range of $25-30 million. So for 78000 km, the cost will be in trillions which is not very attractive (http://en.wikipedia.org/wiki/Transrapid)
2. The actual emission reduction benefits is based on the source of electricity generation - if we use coal, I believe the ecological benefits may not be attractive
Would suggest work on above points to make the case stronger.
All the best, Saravanan.

This proposal is incomplete in many areas. Key questions, such as what the expected impact would be, are not addressed. The idea has merit to it, but the proposal does not outline a feasible and realistic way to get from the highway system we have now to the envisioned system with linear motors. The cost (both in $ as well as in GHGs) is not addressed.
