DAVID GREENE, HOST:

And whether it's worth paying to avoid all blackouts is a theme that has been on the mind of Steven Weissman, he's a professor of Electricity Law at the University of California, Berkeley. We reached him on this blackout anniversary to learn about how the nation's energy system is structured. Weissman says the grid is really made up of several complex networks.

10 Years After The Blackout, How Has The Power Grid Changed?

The sun sets over the Manhattan skyline during a major power outage affecting a large part of the Northeastern United States and Canada on Aug. 14, 2003. Ten years later, some improvements have been made to the grid to prevent another large-scale blackout.

Ten years ago, a sagging power line hit a tree near Cleveland, tripping some circuit breakers. To compensate, power was rerouted to a nearby line, which began to overheat and sink down into another tree, tripping another circuit. The resulting cascade created a massive blackout in the Northeast U.S., affecting power in eight states and part of Canada.

You can thank brainy billionaire Elon Musk's Hyperloop proposal for bringing electro-magnetic-powered transportation and the linear induction motor back into the public consciousness.

The Hyperloop is a system for really-really rapid transit. If built, Musk claims it can carry people about 800 miles per hour, which could get you from Los Angeles to San Francisco in about 30 minutes.

When unapproved genetically modified wheat was found growing in Oregon earlier this year, it didn't take long for accusations to start flying. A flurry of initial finger-pointing cast potential blame on a federal seed vault in Fort Collins, Colo., which housed the same strain of wheat, developed by Monsanto Corp., for about seven years up until late 2011.
