Electric concrete construction vehicles offer reduced noise
Energy-efficient construction vehicles were on display at the recent bauma convention in Munich, including Wacker Neuson Group's DW15e electrically operated wheel dumper and two electric mini-excavators that are quieter than diesel counterparts. CIFA unveiled upgrades to its electric hybrid Energya 9 mixer, which also has reduced noise.

500-square-foot home built in 12 hours using 3D printing
S-Squared 3D Printers built a 500-square-foot concrete home in Patchogue, N.Y., in less than 12 hours. The company, which just signed a contract to build 80 homes in Kansas, said the technology can reduce construction costs by up to 70% and uses the same amount of electricity as a typical hair dryer.

Sand, concrete seen as possible electric reservoirs
Sand or concrete may eventually provide a lower-cost alternative to batteries for storing electrical power. Jason Miller, engineering manager at Echogen Power Systems, is working on a way to transform electrical energy into heat that can be stored en masse in these common construction materials and then converted back into electricity as needed.

Seawalls often use concrete to keep back rising waters
Seawalls can be made using rocks, vegetation or concrete forms, such as on a beach off one of the Cook Islands, to dissipate wave energy while allowing water through, and in Japan where concrete tetrapods are used.

States tackle infrastructure funding as D.C. dithers
Much talk but virtually no prospect of action on federal funding for infrastructure projects has left states to their own devices. Some states are considering alternatives to traditional motor vehicle fuel taxes, which some believe may be rendered obsolete as vehicles become more fuel-efficient.
