PwC ranked 32 countries by their projected global gross domestic product, measured by purchasing power parity (PPP). Compared to projections from two years ago, PWC expects more growth from China up to 2030 and then more of a slowdown. They are also expected slightly slower growth out to 2050 for most countries. The PPP GDP …
Defense Secretary James Mattis is ordering a Pentagon review to compare the capabilities and cost between the emerging carrier-based Lockheed Martin F-35C Lighting II Joint Strike Fighter and an upgraded version of the Boeing F/A-18 E/F Super Hornet, according to a memo obtained by USNI News. The three-paragraph directive orders Deputy Secretary of Defense Bob …
Survivalism, the practice of preparing for the collapse of civilization, tends to evoke a certain picture: the woodsman in the tinfoil hat, the hysteric with the hoard of beans, the religious doomsayer. But in recent years survivalism has expanded to more affluent quarters, taking root in Silicon Valley and New York City, among technology executives, …
Researchers have demonstrated the high-performance potential of an experimental transistor made of a semiconductor called beta gallium oxide, which could bring new ultra-efficient switches for applications such as the power grid, military ships and aircraft. The semiconductor is promising for next-generation “power electronics,” or devices needed to control the flow of electrical energy in circuits. …
NASA has selected two missions that have the potential to open new windows on one of the earliest eras in the history of our solar system – a time less than 10 million years after the birth of our sun. The missions, known as Lucy and Psyche, were chosen from five finalists and will proceed …
South Korea is seeking to develop a train-like public transport concept that is almost as fast as the speed of sound up 1,000 km / h, the Korea Railroad Research Institute (KRRI) said Tuesday. The state-run institute will join forces with other research groups and Hanyang University to build the near-supersonic “train”, which would be …
The Columbia-class ballistic missile submarine program passed its Milestone B decision review and can move into detail design, an official told USNI News. The potential USD128 billion ORP has entered the engineering and manufacturing development phase. These SSBNs should cost about $8 billion apiece, Rep. Joe Courtney (D-Conn.), whose district includes the prime contractor, told …
Here is the 712 page breakdown of NASA $18 billion 2017 budget which provides only a few million for Advanced concepts and innovation projects and has not budgeted a launch of an EMDrive to Space Station. $2.7 billion to operate and manage facilities on the ground. $1.78 billion on Earth science $1.45 billion on Planetary …
Physicists have achieved record levels of temperature reduction using the process of radiative cooling, by which heat is beamed from Earth’s surface into outer space. Zhen Chen and his colleagues at Stanford University lowered the temperature of a thermal emitter – a device designed to give out more heat than it takes in – to …
Scientists have identified an unexpected cause of poor performance in a new class of flexible and cheap solar cells, bringing them closer to market. Solar cells are the building blocks of photovoltaic solar panels. They are made from light-absorbing materials that convert sunlight into electricity. Normally the light-absorbing material is silicon, which has an energy-intensive …
Physicists from the Moscow Institute of Physics and Technology (MIPT) and the Joint Institute for High Temperatures (JIHT) of the Russian Academy of Sciences have described the mobility of line defects, or dislocations, in uranium dioxide. This, they announced this week, will enable future predictions of nuclear fuel behaviour under operating conditions. Their research findings …
