SpaceX will bring point to point travel between major world cities starting near the end of the 2020s if they can increase the safety. It will more likely become significant around 2035-2045. The first spaceports would be in New York, London, San Francisco, Los Angeles, Tokyo, Dubai, Singapore, Shanghai and Beijing. This would be followed …

Globally, more people live in urban areas than in rural areas, with 54 per cent of the world’s population residing in urban areas in 2014. By 2050, 66 per cent of the world’s population is projected to be urban. The world will need to shift to a focus on the degree of urbanization. There will …
A DARPA project could enable radio to be transmitted through water and rock. Radio frequency signals hit veritable and literal walls when they encounter materials like water, soil, and stone, which can block or otherwise ruin those radio signals. This is why scuba buddies rely on sign language and there are radio-dead zones inside tunnels …
A team of University of Washington computer scientists and electrical engineers has demonstrated that it’s possible to generate Wi-Fi transmissions using 10,000 times less power than conventional methods. The new Passive Wi-Fi system also consumes 1,000 times less power than existing energy-efficient wireless communication platforms, such as Bluetooth Low Energy and Zigbee. A paper describing …

Researchers have noted that planet-sized (or larger) artificial structures could be discovered with Kepler as they transit their host star. Jason Wright and other astronomers present a general discussion of transiting megastructures, and enumerate ten potential ways their anomalous silhouettes, orbits, and transmission properties would distinguish them from exoplanets. We also enumerate the natural sources …
