Low & Slow: Folsom Dam's Watershed Agreement abaffyl@enr.com (Luke Abaffy)

It may seen ironic at first glance that the U.S. Army Corps of Engineers and the U.S. Bureau of Reclamation are fasttracking a $900-million effort to address flood-risk and dam-safety issues at Folsom Dam, located near Sacramento, Calif., amid a headline-making, ongoing drought.

The projects we profile in this special section all stretch the limits of what is possible. At first glance, they may seem impossible to build. some of the projects are technically possible to build but may be economically unfeasible.

Dream Projects: Space Elevator as Alluring as a Ball Swung on a String sawyert@enr.com (Tom Sawyer)

The first thing to understand about space elevators is that, in principle, they should work.“A space elevator appears feasible, with the realization that risks must be mitigated through technological progress,” concludes the International Academy of Astronautics in a peer reviewed feasibility assessment with 41 contributors published late last year.

Dream Projects: Bering Strait Tunnel Possible With 'Existing Technology' blairs@enr.com (Scott Blair) Image Courtesy of InterBering LLC The proposed 64-mile long tunnel would intersect with two islands to allow for ventilation and construction access. Related Links: Dream Projects Dream Projects Test New Realities A rail crossing of the 51-mile-wide Bering Strait between Alaska and Russia is certainly not a new dream project—the idea dates back as far as the late 1800s. Since then, numerous railroad magnates, engineers and even heads of state have proposed bridge and tunnel schemes to link the Asian and North American continents. In recent years, a tunnel running underneath the 161-ft-deep channel has been the preferred option.
