Every battery needs recharging, and those that operate the Economy Hub are no exception. We'll be taking time off over the next two weeks. Blogging in that period will be sparse, on an as-needed basis only. Normal programming will resume on April 28.

There's a Stage 2 power alert and I could be taken offline any minute if the California Independent System Operator orders rolling blackouts. But I'm not worried. I have a backup system that will keep my PC running at least two hours--long enough to get through a typical blackout. To test my backup system, I staged my own blackout by switching off the circuit breaker that provides power to my office. I'm still working. I'm writing this column from my desktop PC, which is plugged into an xPower 600 backup power system that delivers 600 watts of AC electrical current.

Kate Spade, Tiffany & Co. and Louis Vuitton — tony retailers at the Westfield Century City mall — are getting a new neighbor, but it won't be another fancy brand. In an unusual move for an automaker, electric car company Coda Automotive Inc. will open its first showroom at the shopping center in July. The automaker is hoping the glitz of those names will rub off on Coda, providing a marketing aura far bigger that what could be expected for a tiny, start-up automaker. Analysts are skeptical.

Getting out in nature for a hike or a trail run can offer an escape from the modern world. But that doesn't mean techie innovations should be left at home, especially when they enhance the experience in a quiet, unobtrusive way. If you want to get there or get back faster and safer, these lightweight devices can help.

Michael Schrage's "Marketers Own the Electric Vehicle's Future, Not Engineers" (Jan. 19) is typical of the political approaches to battery-driven cars, which will not help with what is a problem in basic chemistry. When gasoline and air burn in a cylinder, the transfer of electrons and energy is quick and remarkably complete. Putting a few gallons of gasoline in a tank is fast and easy, while the air supplies itself. Not so with a battery. The same electrons must go through an "oxidizing" reaction, but the oxygen and the fuel must both be within the battery, and the oxidation goes slowly through some "electrolyte."

Re "EPA OKs fuel-cell car production," Dec. 24 I had to laugh reading that the EPA finally got around to approving the California Air Resources Board decision -- made three years ago -- to move away from battery electric technology and allow automakers to satisfy its zero-emissions requirements with fuel-cell vehicles. The irony is that in those three years, many fuel-cell advocates have concluded that the technology is fraught with challenging and expensive engineering problems. They are now once again looking at solutions that involve batteries.

The article by Peter Greenberg (Jan. 18) about hotel/motel fires was very timely and contained much good advice. However, one item not mentioned that I have found helpful is the use of a portable battery-operated smoke alarm. These devices can be easily packed in a suitcase. Fire department personnel advise that the alarm be hung about top of door height near the room entrance. And to avoid false alerts that the battery be disconnected when it is being transported. Even when using a smoke detector it is important to be aware of the location of an emergency exit, and the number of hall doors that must be passed to reach it. MARTHA ABELL Downey
