The final design of what will be the world’s most powerful particle-beam accelerator has been advanced by two crucial decisions made at Sandia National Laboratories in Albuquerque, N.M. The device, shown in the drawing above, will be part of this country’s two-pronged research program to develop an economically feasible means of generating fusion power for the next century.

Cadillac, Buick, and Oldsmobile have the green light from GM management to build their own high-priced sports coupes. How high-priced? Insiders look for these new models to sell in the $35,000 range, and the sky is the limit on luxury materials and convenience equipment.

Performance challenge: turbochargers vs. a V8
Performance is back. Not only are there new performance models, but older designs are being modified for quicker steering, surer handling, and greater engine output. PS tested turbocharged versions of the four-cylinder Ford Thunderbird and V6 Buick Regal against a high-output-V8 Chevrolet Monte Carlo SS to examine the benefits and compromises of two approaches to high-performance driving excitement.

Once the kings of the street, muscle coupes were nearly dealt a death blow by the high cost of fuel in the early 1970s. Gasoline prices went up, fuel-economy laws came on, and the sharp swing to four-cylinder engines pushed the 400-plus-cubic-inch-V8 sedan into extinction.

E. F. LINDSLEY
If you're serious about wood heat, you've undoubtedly seen the claims and counterclaims about new wood stoves. Some catalytic stoves (and aftermarket add-on catalytic units), billed as high-tech devices, sound too good to be true. In an effort to separate the truth from exaggeration, the New York State Energy Research and Development Authority recently funded a series of tests, conducted by Shelton Energy Research, an independent testing firm.

Evan Powell
To loosen, dissolve, and flush away food soils and greases, dishwashers must have just the right detergent for water conditions and water that’s at least 135 degrees F. That’s not in tune with today’s energy-conscious households, in which one way to reduce energy consumption is to lower the water-heater setting to 120 degrees.

Programmable DC motor changes speed or direction
Washing machines, air conditioners, refrigerators, and other appliances would benefit if their speed and torque could be matched to the job. Common AC induction motors are usually locked to a single speed. Now, General Electric has a new motor that changes AC power into DC, then electronically controls power for speed and torque matching. Built-in logic circuits can be programmed for functions such as speed control or activated by outside control circuits.

Just above my head the blades of a ceiling fan whirled slowly. You expect a little hum from any fan, but the electric motor driving this model was eerily silent. As I adjusted a panel-mounted control knob, the fan blades whipped faster until they blurred, slowed, stopped, and then started spinning in the other direction.

S.Renner-Smith
To get whole-house heat from a wood stove, homeowners often must install a large unit in the basement—making loading and monitoring inconvenient. But the Firecone stove installs in the main living area. It works directly with the existing forced-air system, heating the whole house with two loads of wood (or coal) a day, claims SEB, Inc. (2030 Port City Blvd., Muskegon, Mich. 49442).

If two-wheel drive is fine, then four-wheel drive is twice as good—or at least better. That seems to be the thinking at Audi, where four-wheel drive is slowly spreading to all its cars. First there was the $30,000-plus Quattro turbo sports coupe, introduced last year in Death Valley as the ultimate in high-traction, high-performance vehicles.

Pounding your way through hard-packed soil can be a tiring, arm-wrenching task with a conventional front-tine tiller. Every impact of the tines tends to bounce the machine off the ground and tug it from your grasp. Rear-tine tillers, with their forward movement controlled by power-driven wheels, eliminate the tugging.

After testing Green Machine’s model 2400 gasoline-powered hedge trimmer, I decided that what impressed me most were the problems I didn’t have. My hedges are old and tough. They’re also tall, which means a lot of reaching and stretching. I’ve had trouble with other hedge trimmers: jammed cutters on thick, hard growth, blades wedging apart on fibrous twigs, and tired muscles from holding the trimmer at arm’s length.

Oil-fired condensing furnace
The Yukon Ultima oil furnace, using the same condensing technology that brought ultra-high efficiencies to gas furnaces, has achieved 95-percent efficiency in tests. It overcomes accumulation of deposits with a special blower that induces a draft before the burner starts up and after it shuts down. Other condensing oil burners may be on the way.

Holography —out of the lab at last
Dazzling holographic images—3-D pictures made with laser light—fascinate everyone, but holography has never been commercially successful. Now, with new, low-cost methods to create them, holograms are turning up on everything from record-album covers to forgery-proof credit cards. Advanced applications for holograms speed you through supermarkets, simplify testing materials, and even help pilots fly aircraft. More everyday uses are coming.

Wave power spins a ram-air generator
An ingenious new concept to generate electricity, using the power of ocean waves, will be tested in a pilot plant off Scotland’s Outer Hebrides. The 100-foot-tall concrete structure traps a rising and falling column of water that pumps air through a rotary turbine. Long strings of the devices might prove economical for remote islands.

Thinking window can switch off the sun
Cloud Gel is a plastic film that transmits solar energy at temperatures below about 75 degrees and then turns white and reflects it. Used as the glazing on a building, it would help prevent excess solar gain. Day Chahroudi, Cloud Gel’s inventor, has formed a company to develop and commercialize it. Initial uses will be for skylights and greenhouses.

Now there’s a typewriter-size blood analyzer for doctor’s offices, says Eastman Kodak Co. The firm’s $6,000 Ektachem DT60 analyzer uses dry-chemistry slides (inset) like larger hospital-size machines. The operator inserts a disposable-tip pipette containing patient serum or plasma into the machine. A tiny drop is measured onto the slide, which has a bar code read by the analyzer to recognize the test being performed. During the six-minute test, the slide is incubated, starting chemical reactions in its layers. A fiber-optic system helps read the results, which are printed out on a paper slip.

Swiss ingenuity creates a throwaway quartz Swatch
An eyepiece. Tiny screwdrivers. A gray-haired man wearing spectacles leans over a cloth-covered workbench, delicately dropping a gear into place. It’s a classic scene of a Swiss watchmaker at work—at least it was. Now robots and a radically different new watch design create the “Swatch,” a tough, sporty, Swiss-made quartz timepiece with a bargain price.

Say “Swiss watch,” and most people think of the meticulous craftsmanship long associated with the traditional Swiss watchmaker. But now the Swiss are saying “Swatch,” and they’re thinking of tradition and craftsmanship at unheard-of low prices.

Little generators —-power to go
Portable generators can supply power on a camping or boating trip, charge your car’s battery in the woods, or run small hand tools at remote locations. The lightweight wonders can run for hours on a tank of gasoline, and they range in cost from $339 to $799.

I pulled the rope starter on the little Honda EX800 portable generator, and it started to purr immediately. I plugged in my electric lamp, switched it on, and lit up the woods—yet I was miles from the nearest electrical outlet. But what impressed me most about the little power plant was how quiet it was—I could hold a conversation in a normal voice while the generator ran only a few feet away, hushed and smooth.

Replace your patio doors with new energy-effcient double glazing
If you’ve shivered through another winter, it’s time to replace those metal sliding glass doors. The job can be done in one day, and today’s replacement doors are energy efficient. But don’t throw away your old doors—use the glass to create a patio storm door for even more protection.

WILLIAM J. HAWKINS
Those old aluminum sliders are light and need little maintenance—but they’re terrible for keeping out the cold. The aluminum frame is a thermal conductor, and the age of such doors likely means that they no longer seal properly. Even if they did, the single pane of glass does little to help your fuel bill.

Nine practical make-it-yourself safety devices for powertools
Power tools are safer to use when these special shields and jigs, designed by America’s dean of woodworkers, are added. Some of the devices are work holders; others simply keep hands away from cutting edges. They work best when used with respect for the tools they fit and shouldn’t substitute for safety-mindedness.

My hands first appeared in a photograph more than 30 years ago, showing how to use a power tool. Since then, they’ve been in thousands of pictures, and they’re still the same hands—older but whole. I’ve never fallen off a ladder, tripped over debris, suffered an electrical shock, or had to rush to an ophthalmologist to have a foreign substance removed from my eye, either.

At 1:30 p.m., I looked at my bathroom floor and shuddered: This job might be tough. I was getting ready to install Congoleum’s new Accent sheet vinyl. Without a heavy backing layer, Accent is more flexible than other sheet-vinyl floors. Yet its fiberglass-foam backing will bridge shallow cracks, Congoleum says.

On older cars, the brake line’s connector frequently rusts solid to the steel line. During wheel-cylinder replacement, the line is almost always inadvertently twisted and damaged. To avoid that, try this: Cut off the hose near the fitting at the frame end.
