At The Lawrence Livermore Laboratory in California, National Ignition Facility scientists fired up the $3.5 billion laser for its first use against a solid target. The NIF’s 192 lasers were concentrated and funneled into a 30-foot target chamber, and blasted a gold container holding […]

Get a thorough explanation of symbology as it relates to Piping and Instrumentation-controls symbology, tag identification, I/O devices, valve symbol, primary flow element, horizontal line types, dashes, and more.
As I mentioned in Part 2, the meanings of the various symbols used on P&IDs (aka, symbology) are defined on separate drawings called “Lead Sheets” (or Legend Sheets). These are your “secret decoder rings” to P&ID symbology interpretation. Every company that builds process plants should have a set of lead sheets customized to their particular ways and means.

Since 2007, startup Opower has quickly become a leader in energy efficiency - growing from offering simple paper-based energy reports into a full-spectrum, SAAS (software as a service) residential efficiency player, according to greentechmedia.
With mobile apps, a big data business and a thermostat partnership with Honeywell, Opower's got the residential energy landscape covered. How has the company persuaded consumers to reduce their energy use and save $250 million since 2007?
Alex Laskey, Opower's co-founder, explains the simple idea: behavioral science used to created peer pressure. In this TED2013 talk, he explains that “For the last five years, we’ve been running the largest behavioral science experiment in the world.” It's worked. In January, the company achieved a milestone: achieving two terawatt hours of energy savings — enough to take all the homes in a city the size of Sacramento off the electric grid for a year.
