(September 2017) A municipal electrical enclosure In the United States, the National Electrical Manufacturers Association (NEMA) publishes NEMA enclosure typesstandards for the performance of various classes of electrical enclosures. For IEC member countries, standard IEC 60529 is classifying the ingress protection rating (IP Codes) of enclosures. Electrical enclosures are usually made from rigid plastics, metals, particularly stainless steel, carbon steel, and aluminum.
Enclosures for some purposes have partially punched openings (knockouts) which can be removed to accommodate cables, connectors, or conduits. Telecommunication huts are fully assembled or modular field-assembled transportable structures capable of housing an electronic communications system. דף הבית | הטכניון - מכון טכנולוגי לישראל.

The Israel Nature and Parks Authority is celebrating the Sukkot holiday by looking back — way, way back — with a variety of fun and interesting historical re-enactments at national parks around the country. The site of the ancient city of Sepphoris (also Tsippori), “the glory of the Galilee”, is home to Israel’s longest-running reenactment experience and visitors are invited to walk through the site, meet with players, listen to a musical performance, take a guided tours, or participate in art workshops and food stalls.
During Sukkot, Tsippori will open its gates to dozens of artists and artisans in the spirit of Roman times. The Ancient Celebrations at Caesarea will present public performances of theater inspired by arts common in the Roman period: acting, singing and dancing; circus arts, acrobatics and fire shows; stage battles, and musicians playing period instruments such as the harp, lute, flute and drums. תיאטרון אספלט- Asphalt Theatre - בית.

The Weapon Wizards. By Newt Gingrich USA – -(Ammoland.com)- I seldom write about books, but after reading The Weapon Wizards: How Israel Became a High-Tech Military Superpower, I was so impressed that I wanted to share it with you. Written by two veteran defense reporters, the newly released book provides remarkable insight into Israeli weapons development. It is thoughtful and provocative, and a book that I encourage every decision-maker in America to read – including every member of Congress.
The authors, Yaakov Katz and Amir Bohbot, have exceptional knowledge of – and contacts within – the Israeli defense establishment. Throughout the book, they thoroughly discuss how Israel uses innovation, creativity, entrepreneurship, and the application of technology to solve problems. Their descriptions will inspire you to think differently about your own business and career. I suspect the book will also rightly cause some to rethink how innovation occurs in American national security.

Indicators for City Services and Quality of Life, the first international standard on city data, was published in May 2014 by the International Organization for Standardization (ISO). This new international standard was developed using the framework of the Global City Indicators Facility that has been extensively tested by more than 250 cities worldwide.
This is a demand-led standard, driven and created by cities, for cities. ISO 37120 defines and establishes definitions and methodologies for a set of indicators to steer and measure the performance of city services and quality of life. The standard includes a comprehensive set of 100 indicators — of which 46 are core — that measures a city's social, economic, and environmental performance. The indicators are categorized under 17 themes on city services and quality of life. מכון התקנים הישראלי. Connect, a blog by Xcel Energy CDM Bazaar. Contact Support. Home - UNEP DTU PARTNERSHIP.

Emergency and Disaster Information Service. Insights: WRI's Blog. Britain's First Solar Powered Town? Inspiring Story Continues (Video) Image credit: Solarcentury When I wrote about an entire town's plan to go solar, and its incredibly ambitious short-term goal of generating 30% of its electricity from renewables by 2015, the response was enthusiastic. But what's so special about Wadebridge? How are they going about making this happen? How can other communties follow suit? A series of short videos aims to answer these questions and more. Check out the first installment: As mentioned in my previous post on Wadebridge's solar initiative, these efforts have been made possible by the Government's generous feed-in tariffs for solar and other renewables. But it would be wrong to suggest that this is all about subsidies and economics.
With the UK government putting its weight behind legally-binding 50% CO2 cuts by 2025, I hope that this will be the first such story among many.

Utility and Energy Transmission & Distribution News. Street Charge solar charging stations for smartphones make New York debut. Telecomms provider AT&T has partnered with portable solar power systems developer Goal Zero and Brooklyn design studio Pensa for the roll out of Street Charge public solar charging stations in New York. Each station is topped by PV panels that charge up a powerful internal battery to provide smartphone and tablet users with a free juice up. The first units debuted at Riverside Park, Brooklyn Bridge Park, Fort Greene Park and Governor's Island on June 18, and will be followed by another 20 or so stations in the coming months.
The original Street Charge station concepts were designed in early 2012 by Pensa as, according to the group's Marco Perry, "an elegant all-in-one community solution for solar charging of mobile devices. " Development sketches then became working prototypes. One sported an LED street lamp with a PV panel on top, and another was created in collaboration with the Dumbo Business Improvement District with solar panels above sun umbrellas for use in a cafe setting. Solar “tree” from Israel. « Your Solar Link Blog. An Israeli solar “tree” was designed by artist Yoav Ben-Dov. It features solar panels positioned as leaves on metal branches made of pipes and was designed to blend into parks and other green public spaces. Apart from offering shade, Sologic’s eTree has a water fountain, a WiFi hotspot, a docking station to charge devices, and lights up with LEDs at night, according to the company.
“I wanted to integrate the idea of solar energy to the community by creating the eTree,” Sologic chairman Michael Lasry told NBC News. The six-year-old Israeli company got its start by providing solar energy systems to homes and businesses. The first eTree is due to be unveiled Thursday at a park near the town of Zichron Ya’akov, in northern Israel, according to Ynetnews.com. Thinking of Going Solar?
