U.S. NAVY Developing Wave Energy Conversion Device
The U.S. NAVY is researching a device that will convert wave motion to electricity to power emergency equipment in life rafts. The “Lifesaver", a ring-shaped buoy, is being tested to obtain operational data on this particular ocean renewable energy conversion technology. The buoy converts energy generated by passing waves into electrical energy. The Lifesaver project was … [Read more...]
North Korea Interferes with GPS Navigation Systems
Newsweek reported South Korean officials have accused North Korea of using radio waves to interfere with GPS navigation systems near the border between the two countries. This apparently occurred just after North Korea fired a short-range missile into the East Sea. South Korea’s Yonhap News Agency referred to this as an act of “defiance against mounting pressure to give up its … [Read more...]
Fast Radio Burst "Afterglow" Is Actually Flickering Black Hole
Harvard University reported that last February a team of astronomers reported detecting an “afterglow" from a mysterious event called a fast radio burst "which would pinpoint the precise position of the burst's origin." "New research by Harvard astronomers Peter Williams and Edo Berger shows that the radio emission believed to be an afterglow actually originated from a distant … [Read more...]
