Battery electric vehicles (BEV) and plug-in hybrid electric vehicles (PHEV) have high-voltage battery systems used for propelling the vehicle. These battery systems require a means of charging them when not in operation. The most common systems use 300V-400V batteries, although some manufacturers are beginning to specify 800V battery systems as a means of improving vehicle efficiency. Regardless of the battery voltage or type, they need a method for daily charging.
A passion for space exploration runs in Karen Fields’ family. Her father ran NASA’s Zero Gravity program, which trains astronauts for space flight by flying planes in parabolic arcs over the Gulf of Mexico. Her mother supported science experiments for NASA’s payload operations. And as Karen watched the space shuttle missions evolve during her childhood and teen years, she knew she wanted to be part of the NASA mission.

Any parent whose child needs orthodontia knows that there are two kinds of pain that come with the traditional teeth straightening process. There’s the unavoidable pain of moving canines and cuspids, and then there’s the financial pain of paying for it.
Water utilities are expected to become more aggressive in their approach to managing energy
It is no surprise that after labor costs, energy is the next highest operational cost for water and wastewater utilities. Water is an extremely heavy resource, requiring enormous amounts of energy to move and treat it. As energy costs continue to rise and more states adopt regulatory incentives and disincentives that drive large-scale sustainability and efficiency efforts, it is expected that utilities will become more aggressive in their approach to managing energy.
New eBook outlines eight steps to help managers select technologies, plan for power delivery and construct charging facilities
OVERLAND PARK, Kan., July 25 2019 /3BL Media/ – Driven largely by economics, rising air pollution from vehicle emissions and new advances in technology, transportation is transforming and becoming more sustainable, competitive and innovative. U.S. sales of passenger electric vehicles have soared in the last decade. Now, as automakers prepare for mass production of a new line-up of medium- and heavy-duty electric vans, buses, delivery trucks and semi’s, smart fleet and sustainability managers are taking notice.
Data Center operators and businesses need predictability in their power supplies. Their infrastructure has to operate regardless of grid stability, weather conditions and other factors that threaten their systems.
Network problems, IT system failures and hosting disruptions are significant reasons for data center outages. The biggest culprit, though, remains interrupted power supply, according to research from the Uptime Institute.
Interview with Anurag Hans (Essilor) by Carolina Zishiri.
Essilor International's Base of Pyramid (BoP) Innovation Lab develops new inclusive business models and acts as an incubator to test new approaches in partnership with NGOs, foundations and development funds. The BoP Innovation Lab works closely with Essilor’s 2.5 New Vision Generation (2.5 NVG) Division that is responsible for implementing and scaling up inclusive business models. It aims at providing vision care to underserved populations by building a taskforce of skilled primary vision care providers and micro-entrepreneurs in low-income communities.
