Seabed and deep dive submarines and submersible drones and sub hulls with steel and titanium alloys

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 …

Emdrive Roger Shawyer believes midterm EMdrive interstellar probe could flyby Alpha Centauri

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 …

Possible Polar Cap on Pluto

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 …

Transparent Spinel aluminum for transparent armor, next generation lasers, ruggedized smart phones and tablets

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 …
