Nuke Waste Storage Costs Explode
Nuclear power is enjoying a resurgence due to low fuel costs, low emissions, and improved reactor technologies. But nuclear waste storage remains a huge roadblock. POWERnews reports more bad news with a recent increase in the Yucca Mountain storage site costs to $75.6 billion and a delay in site readiness to 2021.

Storm Center Data Goes Public
Should electric utilities make outage data available to the general public in real-time? After investigating the pros and cons of releasing this sensitive data, Florida's SECO Energy said yes. T&D World reports that SECO's Storm Center gives outage information, and also provides estimated times to power restoration. Are such communications plans secure or silly?

Bloggers vs Connectors
If you believe Internet blogs, connector problems may delay the start-up of the Large Hadron Collider. But physicsworld.com's official word is that problems exist with only a small percentage of connectors used in the collider and it is "business as usual" for bringing the new accelerator online. Time will tell who is right.

Relays Run Rambling Wrecks
This Components in Electronics article shows how automotive switches have progressed from mechanical monsters to solenoids to sophisticated electronic relays. Modern automotive relays work at high temperatures, fail safe upon power loss, and operate at very low noise levels. Relays can be networked together using automation protocols such as CANbus.

Seeing the Light at Nanoscale
Until now, you couldn't measure light passing through Nanoscale devices because there wasn't enough room for light to travel in a straight line. ISA reports on a Georgia Tech breakthrough that allows one to predict the behavior of light waves at Nanoscale; opening the door to new Nanotechnologies including solar thermal energy.
