The State Grid Corporation of China Is Running a Smart-Grid Project Using Passive Optical Networking Technology | MIT Technology Review
As well as making the grid more reliable and efficient, the technology could deliver high-speed Internet, TV, and telephony.
hina has begun testing smart-grid technology that could eventually be deployed nationwide to make the delivery of electricity more reliable and efficient. It might also serve as a way to deliver high-speed Internet, TV, and telephony to the farthest reaches of the country.
The State Grid Corporation of China (SGCC) is running the smart-grid project using passive optical networking (PON) technology—a high-bandwidth data wiring that can be run inside electric power cables without interference. Around 86,000 premises in China have so far been connected to the grid; if the project goes nationwide, it would cost around $2 billion to deploy.
Smart grids use computer networking to let utilities monitor everything from electricity use in customers’ homes to the performance of generators at power stations in real time. The concept has gained much attention in the United States but has been slow to catch on. This is partly because regional utilities have different ideas about how to best connect the last mile of the smart grid to users’ homes, says Rajit Gadh, a professor in UCLA’s School of Engineering and Applied Sciences.

The Marines of the future are all about communication.
The Leathernecks want data networks that can keep them connected all the way from the decks of their ships to the beaches they storm. They want online search tools that rely on natural language instead of keywords (like the rest of us). And they want software that can sift through the oceans of data their wartime sensors and cameras collect — including tools that can scan through faces in a crowd, like the Terminator, and alert Marines to danger.
That’s according to the Corps’ blueprint for its science and technology needs over the next 20 years. Communications are a big, gaping hole for the Marines of the present, and the Marines want to hand their successors more seamless, networked ways of talking. That’s on top of other wish-list material, like advanced sensors that can sniff drugs and homemade bombs — oh, and laser-stopping goggles.
The blueprint (.pdf), first published by Inside Defense, doesn’t come out and criticize the Corps’ current suite of communications tools and sensors. But there’s a yawning technological chasm in-between the present-day Marines and where the Leathernecks want to be in 2025.
From “flagpole to fighting hole,” the blueprint writes, Marines need to be in constant communication: “The objective is to provide a holistic, end-to-end, turnkey [command-and-control] capability to execute commander’s intent, facilitate implicit communications, visualize battlespace reality, promote initiative, enable centralized command and decentralized control, and ultimately accomplish the mission.”](http://25.media.tumblr.com/tumblr_m3en8nUr0h1qzs4rbo1_1280.jpg)
