A public-private effort to develop more fuel-efficient automobiles and eventually introduce hydrogen as a transportation fuel is well-planned and identifies all major hurdles the program will face, says a new report from the National Academies National Research Council. Many technical barriers must be overcome and new inventions will be needed, but the program, which was launched three years ago, has already made an excellent start, said the committee that wrote the report.
"The goals of this program are extremely challenging and success is uncertain, but it could have an enormous beneficial impact on energy security and the U.S. economy," said Craig Marks, committee chair and retired vice president for technology and productivity, AlliedSignal Inc., Bloomfield Hills, Mich. "Although it is still too early to speculate whether the program will achieve its long-term vision, it is making significant headway."
The FreedomCAR (Cooperative Automotive Research) and Fuel Partnership, a research collaboration among the U.S. Department of Energy, the Big Three automakers, and five major energy companies, seeks to develop emissions-free and petroleum-free vehicles. The program includes the Presidents Hydrogen Fuel Initiative -- initiated in 2003 to develop technologies for hydrogen production and distribution -- and is a successor to the Partnership for a New Generation of Vehicles, a collaboration between federal agencies and automakers during the Clinton administration.

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.
This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
