Congratulations on your courageous editorial stand opposing the 55-mph speed limit [View Down the Road, Nov. '74]. It is refreshing to see someone speak out for the motorist and against this bureaucratic experiment. First we were told that this speed limit would save energy: that didn't sell.

A new system for electronically identifying vehicles in transit has been developed for the U.S. Army by Fairchild Space and Electronics Company. The key component is a solid-state, batteryless, electronic label, four by five inches and only a quarter of an inch thick.

Reaching over the wings of an airplane, multiple corridors off these movable holding areas would give access to several doors on each side of a plane's fuselage. They'd allow departing passengers to board through one corridor while arrivals were deplaning through another.

Here's a statistic for us TV fans: If you watch TV for three hours a night, and it takes you about two minutes to pick a show between each half-hour commercial, then, believe it or not, you've been doing a deep-knee bend in front of the channel-changing knob for over 70 hours a year—and all the while you thought you were relaxing!

Douglas W. Toms, former head autosafety man for the federal government, was installed as the first president of the Recreation Vehicle Industry Association late last year. Shortly afterward, I had an opportunity to interview him in Los Angeles about his new job, and hear his views about the future of motorized camping and RV safety.

Strip off those extra-cost geegaws, for one thing. You can save a bundle, and make your car cost less to operate, too. Best candidates for your personal cut-back are appearance items like vinyl roofs, white tires, carpeting, and high line trim.

A. J. Hand
PPG’s Herculite K tempered safety glass is tough—about five times stronger than ordinary glass of the same thickness. Trouble is, it’s so tough it can’t be cut. So in the past, glass distributors have been hardpressed to stock it in the 750-odd sizes used in storm doors.

If you are looking for a small American car with slick appearance and plenty of action, you may be tempted by one of these little V8 coupes. But before you buy one, there are a lot of facts you should know. Some of our test results will surprise you: • They are not economy cars, by any definition.

Al Lees
A major response to the energy crunch has been demand for more efficient insulation in homes. While you can stack up thicker blankets above most ceilings, how can you increase insulation in wood-framed walls where studs give you only a 3 1/2" depth to fill?

Jim Roe
Described as an all-purpose recreational boat, Chrysler’s new C-142 Funster can even be equipped with a dinette table. Erecting the soft top and side curtains turns her into a camper. She’s fast enough to pull a skier. Or you can move the swiveling helmsman’s seat up forward to an optional bracket for fishing.

BEN KOCIVAR
Look through the lens of a powerful binocular and the only thing that becomes perfectly clear is that you need a tripod to keep it steady. And, on a boat or in a moving car, high-power scopes are simply useless. Useless until now. Recently, I tried a new prismatic scope called Stedi-Eye.

Editor-in-Chief
The new logic in small-car engineering we refer to on our cover this month is so obvious you have to wonder why it has taken so long for the ideas to achieve dominance in the thinking of small-car designers. Of course those of you who are students of automobile history will recognize that the ideas are not exactly new.

JAN P. NORBYE
Detroit makes subcompacts that weigh from 2600 to 3000 pounds and give 20-26 mpg. They have front engines and a driving rear axle. That’s not what small-car engineering is all about. Some of the cars I am talking about weigh 1300 to 1800 pounds and give 30-45-mpg fuel economy.

The once-fertile fields are dry now, and the dead peanut shoots poke yellow and stiff through the orange-gray dust. A skeletal goat wanders by, alone, looking for something green. Off behind an abandoned termite nest stands his brother, bloated and maggoty.

From the cornfield where I stood, high on a plateau 35 miles north of Denver, I could see the outlines of a stark, metal-hued building.

By now, almost everyone knows that internal-combustion engines will run on hydrogen. But there are problems—mainly because of hydrogen’s high combustion speeds and an unexplained tendency for it to cause backfiring. What’s new is any little step in technology that will make hydrogen engines run better without complex, exotic, and expensive modifications.

You’re about to rip a sheet of plywood. You set the fence, begin to push the wood through . . . and curse quietly as the end of the panel slips sideways into the blade.

How to Build Your Own Living Structures
$4.95
The author and his works will be familiar to longtime readers of this magazine, since several of the 12 projects detailed in this book first appeared as PS Lie-Flat Blueprints—from the Superchair [March '68] through the beach-site Fun House [July '69]. Some of the book's projects and all of its photos and sketches are new. The sketches, particularly, are a delight—crisp and informative. Most of the photos have that "in" look affected by today's casual youth (stacked-carton storage and fingercombed hair may well look dated in a few years).

It pays to keep up with the ''alternate-lifestyle” press: Unconventional attitudes help reorder priorities and remind us of the difference between a route and a rut. So here's a batch of paperbacks too specialized, too weird, or too new to have made our December listing of DIY classics—in the order pictured: • How to Build Your Own Living Structures, by Ken Isaacs; Harmony Books, 419 Park Ave.

RAY HILL
Because of its unwieldy shape, a carburetor can be difficult to keep in a position that allows easy access. One solution: Clamp a tapered punch in a vise, and slip one of the carb's mounting holes down over the punch. This way the carb isn't marred by vise jaws, and it can be lifted off, rotated, or placed in an inverted position, as required.

Carl R. Sager
Lowering your thermostat cuts your fuel use—and your fuel bill. The U.S. Dept, of Commerce estimates that a homeowner in Bismarck, N.D., can reduce fuel consumption by two percent for each degree he lowers his thermostat; in Pittsburgh, he’d cut off three percent; in Portland, Ore., four percent; and in Columbia, S.C., five percent.

I have two questions about tires: Are recapped tires a good buy nowadays? And can radials be recapped? Tony Orlando, New York, N.Y. That depends. In a country such as France, where all tires are radial and designed to be recapped, the answer is simple: yes.

The sturdy handles are cleverly rigged for three optional working heights, and for vertical or folded storage.

JUDY FISCHER
Last November, a section of a heavily traveled expressway in New York City had to be repaired. If it had been done the usual way, traffic on this major artery would have been detoured through narrow streets for three to four days while the new concrete cured.
