Protecting Japan from tsunamis
As Japan begins to rebuild after the massive 9.0 magnitude earthquake and tsunami, engineers are beginning to analyze the destruction to learn how to better prepare for future natural disasters; one expert says that prior to the earthquake, more infrastructures spending, particularly for projects aimed at preventing the approaching tsunami, could have mitigated much of the damage; the tsunami easily overwhelmed one of the tallest and longest seawalls in Japan; officials will have to decide whether to reinvest in costly tsunami infrastructure or to relocate communities further from the ocean to minimize the numbers affected by such events

Record number of infrastructure funds raising money, worst results in years
More private-equity infrastructure funds are seeking to raise money around the world than ever before, but with the increase in competition, funds are struggling to reach their funding goals; 131 unlisted infrastructure funds are seeking to raise a total of $92.1 billion; so far only two infrastructure funds reached their fundraising goals, raising a total of $600 million, the lowest amount in seven years; in the first quarter of 2010, seven funds met their goals raising a total of $7.5 billion dollars; infrastructure funds will likely become more popular as inflation rises but analysts expect funds to raise less money than in previous years

Waste ash from coal could save billions in repairing U.S. bridges and roads
The more than 450 coal-burning electric power plants in the United States produce about 130 million tons of “flyash” each year; before air pollution laws, those fine particles of soot and dust flew up smokestacks and into the air; power plants now collect the ash; researchers say that coating concrete destined to rebuild America’s crumbling bridges and roadways with some of the millions of tons of that left-over ash could extend the life of those structures by decades, saving billions of dollars of taxpayer money

Senate proposes new $10 billion "infrastructure bank"
Several U.S. Senators are pushing for the creation of a $10 billion “infrastructure bank” to spur investment in new infrastructure and to repair America’s rapidly aging roads, power grids, and bridges; the bill could attract as much as $640 billion in private investment over the next ten years; the Obama administration has proposed a similar plan; the bank would be self-sustaining as it is not allowed to finance more than 50 percent of a project’s costs; this bill faces an uncertain future given the current Congressional budget climate

Shift of Earth's magnetic north pole affects Tampa airport
Magnetic changes in the core of the planet shift the Earth’s magnetic pole at nearly 40 miles a year toward Russia; as a result, Tampa, Florida, International Airport has closed its primary runway so it could be redesignated 19R/1L on aviation charts; it has been 18R/36L, indicating its alignment along the 180-degree approach from the north and the 360-degree approach from the south; the FAA required the runway designation change to account for the shift in the Earth’s magnetic pole

Recycled Haitian concrete safe, strong, cheap
Nearly a year after the 7.0 magnitude earthquake, most of the damaged areas of Haiti are still in ruins; researchers find that concrete and other debris in Port-au-Prince could be safely and inexpensively recycled into strong new construction material which meets or exceeds the minimum strength standards used in the United States

Groundbreaking for $1.2 billion NSA Utah center
Today is groundbreaking day for the Utah Data Center, a $1.2 billion project which will employ more than 10,000 people for its construction, and is thus seen as the salvation for the state’s beleaguered construction industry; the National Security Agency (NSA) will use the climate-controlled environment of its computerized core as a repository for information gathered by different branches of the country’s intelligence apparatus, hence the facility’s nickname, “The Spy Center.”

China, U.K. pursue major rail projects; U.S. does not
Unlike almost every other developed nation, the United States has no national transportation strategy; the nation fails to raise taxes that are supposed to pay for roads and rails. Gasoline taxes, for example, cover only about 50 percent of road projects, much lower than in the past, according to recent Federal Highway Administration figures; once the U.S. recognizes that it needs diversified and integrated air, rail and road transportation, it could well end up importing the technologies, products and expertise it has failed to develop

Giving crowds a lift with spiral escalator
A monorail-inspired design could help create the world’s first continuous spiral escalator; the spiral escalator could transport larger numbers of people than a lift in a vertical space too narrow for a traditional escalator; this could reduce the floor space needed in buildings for personal transporters and cut the cost of putting escalators into underground railway stations

Quake experiments may lead to sturdier buildings
Johns Hopkins researchers will study how seismic forces affect mid-rise cold-formed steel buildings, up to nine stories high; the cold-formed steel pieces that are commonly used to frame low- and mid-rise buildings are made by bending about 1-millimeter-thick sheet metal, without heat, into structural shapes; these components are typically lighter and less expensive than traditional building systems and possess other advantages

Thirteen Georgia dams could be reclassified as high risk
The number of dams designated high risk under Georgia’s Safe Dams Act could more than double in two counties in the state, but a backlog in state enforcement because of budget cuts could drag the reclassification process out years longer than scheduled

Minneapolis bridge collapse spawning new bridge research
Oregon State University developed a new system to analyze the connections that hold major bridge members together; the work also brings focus to a little-understood aspect of bridge safety — that most failures are caused by connections, not the girders and beams they connect, as many people had assumed. The issues involved are a concern with thousands of bridges worth trillions of dollars in many nations

Bacteria knit together cracked concrete
Students at Newcastle University genetically modified a microbe, programming it to swim down fine cracks in the concrete; once at the bottom, it produces a mixture of calcium carbonate and a bacterial glue which combine with the filamentous bacterial cells to “knit” the building back together
