3D printed metamaterial can cause energy gain

Hao Xin, a professor of electrical and computer engineering, has discovered synthetic materials which might one day be used to build microscopes with superlenses and even ‘shields’ which could render military equipment and people invisible to the naked eye. Xin uses metamaterial building blocks and 3D printing to create startling results. These metamaterials, which can …

DARPA robot can learn tasks from Youtube video and a neural net can understand video 20 times faster than a human

A startup called Clarifai is offering a service that uses deep learning to understand video. The company says its software can rapidly analyze video clips to recognize 10,000 different objects or types of scene. In a demo given last week at a conference on deep learning, Clarifai’s cofounder and CEO Matthew Zeiler uploaded a clip …

USA arming Ukraine likely to trigger Russia to sell thousands of surface to air missiles

The USA is moving towards sending weapons to Ukraine. Putin and the Russians may have intentionally shot down the Malaysian commercial jet. This would have been a warning that they could proliferate their missile technology to Al Qaeda or ISIS. The Russians may have shoulder launched missiles which can down commercial jets at cruising altitudes …

Lithium ion sulfur with polymer membrane safe enough for future car batteries with improved 750 to 2700 Wh/kg energy density but still need longer life cycle

Greencarcongress reports researchers added a polysulfide to the polymer membranes during their synthesis with the aim to reduce the cathode dissolution during operation. To improve the room-temperature ionic conductivity of the polymer electrolyte, they plasticized the LiS8 added membrane. The resulting LixSn-C/GPS-Li2S8/S-C lithium-ion sulfur cell is characterized by a high safety level, due to the …

Supercritical-Water-Cooled Reactor

Supercritical-Water-Cooled Reactor (SCWR) are high temperature, high-pressure, light-water-cooled reactors that operate above the thermodynamic critical point of water (374°C, 22.1 MPa). The reactor core may have a thermal or a fast-neutron spectrum, depending on the core design. The concept may be based on current pressure vessel or on pressure tube reactors, and thus use light …

Worldwide Extreme Poverty Reduction has mostly been the rise of China but next is India and Africa

Worldwide extreme poverty reduction has mostly been the economic rise of China. Further reduction in extreme poverty will mostly be about success in India and then Africa. Americans have not only not been aware of the success against extreme poverty but mainly believe the opposite that poverty has increased and do not believe that poverty …
