Move Over Electricity Gas and Water Meters Are Getting Smart

Greentech Media has a report on the expansion of smart metering to water and gas - Move Over, Electricity: Gas and Water Meters Are Getting Smart.

For all of the chatter about smart meters, the conversation rarely wanders far from the realm of electricity. But action is starting to heat up in the smart gas meter market, and water isn’t far behind.

Last week, consulting group Capgemini announced it was chosen by Southern California Gas Company (owned by Sempra) to install more than six million smart meters in the next five years, the largest gas-only utility smart meter project in the U.S. SoCalGas’s project is part of a nearly three-fold increase in the penetration of smart gas meters worldwide estimated by Pike Research between 2010 and 2016.

“The gas grid is certainly a different animal,” said David DuCharme, vice president of Utility and Smart Energy Services at Capgemini. “The largest issue is safety and management.”

In Europe, there is already more activity in the gas market; the U.K. government has mandated dual gas and electric smart meters for every home and business by 2020. Italy will install smart meters for all of its commercial gas customers and most residents by 2016.

Yet in the U.S., gas metering has not received as much attention -- or as many federal dollars -- as electric smart metering. However, the challenge of managing gas smart grid data can be less complex than electric meter data management, according to DuCharme. As prices continue to drop for the smart meter market, this will benefit the gas market, as well.

Like their electric brethren, gas utilities have struggled with integrating IT and OT when implementing the new metering systems. Capgemini, which has doubled its accounts in the smart energy space to 40, is finding increasing success with gas utilities. In the case of SoCalGas, about 30 different vendors will provide the meters; Aclara is providing the MDM system.

Water is also on the horizon. “The cost of efficiently managing infrastructure in the gas and water industry is extremely important,” said DuCharme. For those who think the electric grid in the U.S. is aging, the water infrastructure in much of the world is downright elderly. One study from Frost & Sullivan estimates the European smart water meter market will be worth $20 billion by 2020 and will see double-digit growth in the next decade.

Why stem cells are stem cells

This seems like a pretty fundamental finding regarding what makes a stem cell a stem cell:

Five Genetic Themes Key To Keeping Stem Cells In A Primitive, Flexible State Have Been Identified

For more than 25 years, stem cells have been defined based on what they can become: more of themselves, as well as multiple different specialized cell types. But as genetic techniques have become increasingly powerful, many scientists have sought a more molecular definition of stem cells, based on the genes they express.

Now, a team of Canadian scientists has identified 1,155 genes under the control of a gene called Oct4 considered to be the master regulator of the stem cell state. A comprehensive molecular definition of stem cells is emerging: according to this research, stem cells are cells that keep their DNA packaged in a flexible format, keep cell division tightly controlled, prevent signals that might trigger death, repair DNA very effectively, and reinforce all of these characteristics by tightly controlling how molecules can move within the nucleus.
