https://www.theguardian.com/business/2017/may/04/nissan-launches-british-made-home-battery-to-rival-teslas-powerwall Batteries that have powered electric cars around the UK will get a second life providing energy storage for households, with the launch this week of a British-made home battery to rival the one made by Elon Musk’s Tesla. I mentioned Tesla battery a year ago in this blog at http://www.epanorama.net/newepa/2015/05/02/watch-elon-musk-announce-tesla-energy-in-the-best-tech-keynote-ive-ever-seen-the-verge/ →
http://spectrum.ieee.org/tech-talk/aerospace/space-flight/scientists-figure-out-possible-new-threat-to-spacecraft Micrometeoroids don’t pack enough punch to get through a spacecraft’s hull. But according to new simulations reported this week in the journal Physics of Plasmas, they can generate a potentially crippling pulse of radio-frequency radiation. →
https://www.wired.com/2017/05/hundreds-apps-can-listen-beacons-cant-hear/?mbid=social_fb THERE ARE PLENTY of privacy-invading marketing ploys to worry about in life. Some examples are easy to notice, some are more subtle. In the most inconspicuous hustle of all, apps have increasingly incorporated ultrasonic tones to track consumers. →

A Doppler radar is a specialized radar that uses the Doppler effect to produce velocity data about objects at a distance. It does this by bouncing a microwave signal off a desired target and analyzing how the object’s motion has altered the frequency of the returned signal. Doppler radar technology used to be expensive, but →
https://semiaccurate.com/2017/05/01/remote-security-exploit-2008-intel-platforms/ This looks quite nasty security issue for very many PCs. It seems that Intel has confirmed it. You can read their advisory here. The short version is that every Intel platform with AMT, ISM, and SBT from Nehalem in 2008 to Kaby Lake in 2017 has a remotely exploitable security hole in the ME (Management Engine) →
Cell phones do not work on tunels and other undeground contructions without help because many meters of earth, stone, concrete and steel to block the RF signals. To make cell phones to work underground, you need to build some sort of structure that allows signals to pass through so you can access your wireless data. →

They are an inexpensive way to make applications aware of their surroundings. With beacons no user action is required for an application to obtain the proximity information. When a smartphone enters the range of a beacon, →
