Atmospheric lens could revolutionize the future of battlefield observation. BAE Systems has been working on a way to use lasers to actively reshape the atmosphere to turn it into a variety of optical tools. The Laser Developed Atmospheric Lens system (LDAL) uses powerful laser pulses to make air itself into lenses, mirrors, and even protective …
Pan-STARRS researchers reported the detection of seven Neptune Trojans (NTs) in the Pan-STARRS 1 (PS1) survey. Five of these are new discoveries, consisting of four L4 Trojans and one L5 Trojan. Orbital simulations show that the L5 Trojan stably librates for only several million years. This suggests that the L5 Trojan must be of recent …
China will expand its railway network to 150,000 km (93,200 miles) by 2020, including 30,000 km of high-speed rail, the country’s top economic planner said on Wednesday. The plan will mean a 24 percent increase in the length of China’s railway network from 2015 and a 58 percent expansion in high-speed rail. The government will …
Airborne wind energy seem simple. You would use kites, gliders, rotors or lighter than air constructs (different air filled shapes) to capture wind energy at higher altitudes. The wind is stronger and more consistent at higher altitudes and the systems could use 100 times less material than conventional wind turbine systems. Many promising possibilities remain …
Exciting progress towards spin-based quantum computing has recently been made with qubits realized using nitrogen-vacancy centres in diamond and phosphorus atoms in silicon. For example, long coherence times were made possible by the presence of spin-free isotopes of carbon and silicon. However, despite promising single-atom nanotechnologies6, there remain substantial challenges in coupling such qubits and …
Senseg patented solution creates a sophisticated sensation of touch using Coloumb’s force, the principle of attraction between electrical charges. By passing an ultra-low electrical current into the insulated electrode, Senseg’s Tixel™, the proprietary charge driver can create a small attractive force to finger skin. By modulating this attractive force a variety of sensations can be …
Carnival of nuclear energy 40 is up at the ANS nuclear cafe Nextbigfuture provided the review of the minimal amount of reactor certifications in the 36 years of history of the Nuclear Regulatory Commission. Brave New Climate looks at different scenarios for the nuclear fuel cycle Consider four simplistic scenarios, highly idealized to emphasize the …
