Induction and Flexible Electronics for Wireless Power

Lynne Kiesling Check out this Technology review article about using flexible electronics to enable wireless powering of devices through induction. Nikola Tesla, spin over in your grave and call your office! The power sheet, says Takao Someya, professor of engineering at the University of Tokyo, relies on the well-known physical principle of electromagnetic induction, used …

Transmission, Congestion Charges, and the Smart/Modern/Intelligent Grid

Lynne Kiesling Mike beat me to it in commenting on David Cay Johnston’s NYT article from Wednesday about grid congestion. My thoughts are somewhat different from Mike’s, for what it’s worth. Johnston hits on one of the most pressing problems in electricity restructuring, although I’m going to frame it differently from how he does: technological …

He’s Ba-a-Ack! Another Nyt Article on Electric Industry Restructuring

Michael Giberson David Cay Johnston is back with another in his series of articles on electric industry restructuring, this one concerning transmission congestion. Another important sign of worsening congestion is a sharp increase in requests by network operators to prevent overloads that could disrupt transmission on the PJM Interconnection, the network serving 51 million people …

Plug-in Hybrid Autos Could Put Off-peak Power Generators to Good Use

Michael Giberson If all the cars and light trucks in the nation switched from oil to electrons, idle capacity in the existing electric power system could generate most of the electricity consumed by plug-in hybrid electric vehicles. A new study for the Department of Energy finds that “off-peak” electricity production and transmission capacity could fuel …

Landfill Gas and Bovine Flatulence: New Energy Supplies

Lynne Kiesling Landfills, mines, and livestock give off methane, a form of natural gas that could be used as fuel if it were captured and recycled in some useful way. Methane is also a potent greenhouse gas, and some research shows that controlling methane may actually lead to larger effects than controlling carbon dioxide emissions. …

“Trade Deficit”, Oil Prices, and Other Items of Interest

Lynne Kiesling When I read today that October’s US trade deficit dropped to a 14-month low, I had my usual reaction to news items about the trade deficit: so what? Why should (exports-imports) be an indicator of anything of substance in a world of relatively free trade with flexible exchange rates? Sure, there are complex …

Romancing the Supply Chain

Michael Giberson Worthy of note for the film-going economists out there, Ann Hornaday sees “A Spike in Supply-Chain Muckraking”: An unlikely star has emerged of late on the Hollywood firmament, one buried for years under a bushel of white papers, think tank policy recommendations, IT memos and unread op-eds. Ladies and gentlemen, for your consideration: …

“Drive Less!” Campaign is Working

Lynne Kiesling Tongue in cheek, Tim Haab claims some credit for helping to bring about the shift in consumer behavior documented in a recently-released Cambridge Energy Research Associates study on gasoline. Punch line: America’s “love affair with the automobile” is being transformed — but not broken up — by forces that are redrawing the global …
