Inexpensive catalyst for producing hydrogen under real-world conditions found:
Hydrogen has been hailed as the fuel of the future, but producing it cleanly using platinum as a catalyst is simply too costly to service the world's energy needs. On the flipside, producing hydrogen with fossil fuels not only releases CO2 as a byproduct, but is unsustainable, negating hydrogen's green potential. However, hydrogen may yet make good on its promise thanks to a group of scientists at the University of Cambridge...

Blade Dynamics to make first 100-meter wind turbine blades?
Blade Dynamics to make first 100-meter wind turbine blades?:
The Energy Technologies Institute in the United Kingdom has announced that UK-based wind turbine blade manufacturer Blade Dynamics has been awarded a contract that will see the creation of the world's longest turbine blades, between 80 and 100 meters (262 and 328 feet) in length. Currently, the longest turbine blades are for offshore wind farms, maxing out at 75 meters (246 feet)...

FAA Publishes Modified Noise Rules For Tiltrotors
FAA Publishes Modified Noise Rules For Tiltrotors: Brings U.S. Regulations Into Agreement With ICAO Standards The FAA has published a rule in the Federal Register governing noise certification standards for issuing type and airworthiness certificates for a new civil, hybrid airplane-rotorcraft known as the tiltrotor. This noise standard establishes new noise limits and procedures as the basis to ensure consistent aviation noise reduction technology is incorporated in tiltrotors for environmental protection.
