Dubai’s skyline is an ever-growing collection of impressive towering skyscrapers, including the Burj Khalifa, the tallest building in the world. And you know what loves tall buildings even more than tourists do? Lightning.

Instagrammer faz3, also known as Sheikh Hamdan Bin Mohammed Bin Rashid Al Maktoum (the Crown Prince of Dubai), captured this amazing lightning show over Dubai at 1,977 frames per second, turning what is normally a split second occurrence into a beautifully drawn-out ballet of bolts splintering their way across a dark stormy sky.

AlphaGo (via DeepMind’s Aja Huang) vs. Sedol in last minute of Match 1 (credit: DeepMind)

Google DeepMind’s machine-learning AlphaGo program has defeated South Korean Go champion Lee Sedol in the first match of five historic matches between human and AI, taking place in Seoul.

The second round will take place today (Wednesday March 9 in U.S.) at 11 PM ET (1 PM KST), also covered on YouTube.

An interstellar precursor mission has been discussed as a priority for science for over 30 years. It would improve our knowledge of the interstellar environment and address fundamental questions of astrophysics, from the origin of matter to the evolution of the Galaxy. A precursor mission would involve an initial exploration probe and aim to test technological capabilities for future large-scale missions. With this survey we intend to identify potential backers and gauge the public’s interest in such a mission.

This survey is conducted by the International Space University (www.isunet.edu) in collaboration with the Initiative for Interstellar Studies (www.I4IS.org). Your data will not be shared with any other organisation.

The preview image below thanks Robert Bradbury(no not Ray Bradbury) who is no longer with us but you can find his work concerning Matrioshka Brains and he has a great life extension lecture on youtube.

The author greatly appreciates and thanks Robert J. Bradbury for doing the painstaking and often tedious original html coding job for 25 of these papers, among the many linked papers cited on this page.

The realities of VR.

NEW YORK, March 7, 2016 /PRNewswire/ — Horizon Media, the largest and fastest growing privately held media services agency in the world, announced today its most recent research on consumer interest in virtual reality devices. The research was fielded in Finger on the Pulse, the agency’s proprietary online research community comprised of 3,000 people reflective of the U.S. population, and with the social media expertise of Horizon’s Distillery social intelligence team. The research shows that despite extensive media coverage of Oculus Rift, Samsung Gear VR, Google Cardboard and other virtual reality devices, fully two thirds of consumers are unaware of the technology.

Virtual reality – often referred to as “VR” – has been readily embraced by the mainstream media as the shiny, new, technological advancement. Marketers are also understandably excited about the possibilities unleashed by VR technology. But while there is interest among consumers, the survey findings suggest that companies would be well served to walk before they run when incorporating virtual reality activations into marketing plans, at least until the technology reaches greater awareness and scale.

Consumers are open to a VR enhanced future, but believe it will take several more years to get there. Unaided awareness of the major devices is fairly low at just 33%. However, more than a third (36%) say they are interested in owning some sort of virtual reality device. In addition Horizon’s Distillery social intelligence team found that 9% of online discussion around the topic is related to positive purchase interest. In fact, compared to the Apple Watch before its release, VR got much more love from Finger on the Pulse panelists. Twice as many consumers consider VR “an exciting new innovation to own” (82% for VR vs. 44% for Apple Watch), and twice as many say “everyone is going to wish they owned one” (55% for VR vs. 24% for Apple Watch). A strong majority of consumers (81%) also believe that five years from now, anywhere from a quarter to half of the population will own a VR device.

Two big problems have been vexing environmental scientists for decades: How to store solar energy for later use, and what to do with CO2 that’s been captured and sequestered from coal plants? Scientists from General Electric (GE) could solve both those problems at once by using CO2 as a giant “battery” to hold excess energy. The idea is to use solar power from mirrors to heat salt with a concentrated mirror array like the one at the Ivanpah solar plant in California. Meanwhile, CO2 stored underground from, say, a coal plant is cooled to a solid dry ice state using excess grid power.

When extra electricity is needed at peak times, especially after the sun goes down, the heated salt can be tapped to warm up the solid CO2 to a “supercritical” state between a gas and solid. It’s then funneled into purpose built turbines (from GE, naturally) which can rapidly generate power. The final “sunrotor” design (a prototype is shown below) would be able to generate enough energy to power 100,000 homes, according to GE.
