Flood-proofing New York City with storm barriers
New York City faces two problems with water: rising ocean level and surges created by hurricanes and Nor’easters; engineers propose a system of barriers to prevent New Orleans-like flooding

Rotating space elevator propels its own load
The first proposal for a space elevator was put forth in 1895; all space elevators ideas and concepts since then relied on internal engines, laser light pressure, or any kind of propulsion to propel the elevator and its load skyward — until now: researchers say it is possible to conceptualize an elevator which propels its own load

Glass-based coating for reinforcement bars for sturdier infrastructure
Researchers develop glass-based coating for reinforcement bars that helps prevent corrosion and strengthens the bond between steel and concrete; the material could help engineers build stronger bridges and increase the longevity of other steel-reinforced structures

U.S. reassesses safe water levels in New Orleans' outfall canals
New Orleans has three outfall canals, the role of which is similar to that of a storm drain under a city street; since Katrina, there have been disagreements among engineers as to how much water would it be safe for each of the three canals to handle during a storm

Chemical robot shows possibility of electronics-free robots
The Belousov-Zhabotinsky (BZ) reaction is one of a class of chemical systems in which the concentration of one or more compounds periodically increases and decreases; the oscillation thus generated creates an autonomous material that moves without electronic stimulation; door opens for future chemical robots: they will be “self organized” and generate their own control and mechanical signals from within

Experts: Levees will not save New Orleans from Katrina-like storm
National Academy of Engineering panel says that even the strongest levees and flood walls cannot be guaranteed to save New Orleans from another hurricane like Katrina

Self-healing concrete for safer, durable, and cheaper-to-maintain infrastructure
Wolverines researchers develop self-healing concrete; the concrete self-heals itself when it develops cracks; no human intervention required — only water and carbon dioxide

U.K. government's budget proposal attracts lukewarm reaction
Chancellor of the Exchequer Alistair Darling’s budget — described by the chancellor as “the world’s first carbon budget” — offers support to U.K.’s fast-growth technology sector, but some say it is not enough; EFF’s Gilbert Toppin: “The measures are helpful though he should have gone further to make a real difference”

Russia to build new-generation nuclear icebreaker by 2015
Russia is locked in legal dispute with four other countries over rights to the mineral-rich areas in an under the North pole — areas which are slowly becoming accessible as a result of global warming; to make sure it gains ready access, Russia invests a new generation of nuclear ice breakers

Post-Ike ideas for defending Galveston include extending sea wall
Texas A&M oceanographer proposes extending Galveston’s seawall to the island’s West End, building a similar structure along Bolivar Peninsula, and constructing massive Dutch-like floodgates at the entry to Galveston Bay; oceanographer says his proposed wall and gate system could repel most surges

Composite materials extend life of existing bridges
The Obama administration’s stimulus package directs large amounts of money toward rehabilitating the aging U.S. infrastructure; Jayhawks researchers are testing a new class of devices that could double the life of America’s existing bridges using composite materials
