1. Yes Vermont Yankee Blog: Atoms Not Dams: Surprising Facts for Earth Day. Noting Jim Conca’s post on the biggest power plants (by electricity produced, not by nameplate), I note that Vermont Yankee was a bigger power plant (produced more power per year) than Hoover Dam. Every Day is Earth Day when you support nuclear …
There have been proposals to have a new class of seabed operating military submarines. They operate undetected on the ocean floor where hills and rocks reflect sonar and magnetic detection. The average depth of the ocean is about 14,000 feet. The pressure on a submarine’s hull increases with depth, limiting the depth below the ocean …
Jeff Bezos’ Blue Origin’s New Shepard space vehicle as it makes its first developmental test flight. Yesterday Blue Origin flew the first developmental test flight of our New Shepard space vehicle. Our 110,000-lbf thrust liquid hydrogen, liquid oxygen BE-3 engine worked flawlessly, powering New Shepard through Mach 3 to its planned test altitude of 307,000 …
Roger Shawyer invented the Emdrive. NASA is testing the EMdrive and the Cannae drive and getting interesting results Shawyer presented in October, 2014. EMDrive results have not been conclusively proven yet and there is no proven underlying theory and any scaling has not been determined. There are interesting results in the 50-900 micronewton ranges. There …
For the first time, images from NASA’s New Horizons spacecraft are revealing bright and dark regions on the surface of faraway Pluto – the primary target of the New Horizons close flyby in mid-July. The images were captured in early to mid-April from within 70 million miles (113 million kilometers), using the telescopic Long-Range Reconnaissance …
On March 27, DARPA successfully tested the full Persistent Close Air Support (PCAS) prototype system for the first time as part of TALON REACH, a U.S. Marine Corps infantry/aviation training exercise conducted in the southwest region of the United States in partnership with the Marine Aviation Weapons and Tactics Squadron One and the Marine Infantry …
The Ericsson Mobility Report Mobile World Congress edition, February 2015 predicts continued growth in mobile subscriptions and traffic over the coming years. It also looks at the surging demand for mobile broadband, the growth in popularity of streaming video and the transition towards LTE in all regions. Africa had 880 million mobile subscribers at then …
A root cellar is a structure built underground or partially underground and used to store vegetables, fruits, and nuts or other foods. Root cellars are for keeping food supplies at a low temperature and steady humidity. They keep food from freezing during the winter and keep food cool during the summer months to prevent spoilage. …
QUT biofabrication team has made a major breakthrough by 3D printing mechanically reinforced, tissue engineered constructs for the regeneration of body parts. In an article published in Nature Communications, the biomedical engineers outlined how they had reinforced soft hydrogels via a 3D printed scaffold. Professor Dietmar W. Hutmacher, from QUT’s Institute of Health and Biomedical …
IBM scientists today unveiled two critical advances towards the realization of a practical quantum computer. For the first time, they showed the ability to detect and measure both kinds of quantum errors simultaneously, as well as demonstrated a new, square quantum bit circuit design that is the only physical architecture that could successfully scale to …
Imagine a glass window that’s tough like armor, a camera lens that doesn’t get scratched in a sand storm, or a smart phone that doesn’t break when dropped. Except it’s not glass, it’s a special ceramic called spinel {spin-ELL} that the U.S. Naval Research Laboratory (NRL) has been researching over the last 10 years. “Spinel …
