Roller coaster tech helps U.S. Navy with its need for speed Video Transcript
-The newest roller coasters are over the top. Setting records for height and speed and sending riders through a dizzying series of loops and turns. Many of the scream-inducing drops and stomach-turning twists are made possible with electromagnetic technology called linear synchronous motor or LSM. Instead of climbing up a steep incline and using gravity to gain speed, LSM allows roller coasters to accelerate from a standstill to high speeds within seconds. -We can go higher and faster than we have before. Conventional lifts, we can only go so high. With some of our launched coasters, we're doing 450 plus feet in the air versus 300 foot on conventional lift coasters. -The Superman: Ultimate Flight ride at Six Flags Discovery Kingdom uses LSM to create a non-inverted loop, a rare feature in park rides. -In your refrigerator at home, you have a motor and it's a circular motor. And all we've done is we've taken that and we've laid it out flat so that instead of power moving in a circular motion, it moves in a linear motion. -The coasters are powered by supercomputers and electromagnets. -The easiest way to explain this is like, if you remember when you were a kid, you took magnets and you pushed them together and they repelled each other? It's basically the same concept. -LSM not only propels the train to speeds over 60 miles per hour, it's also used in the braking system to slow it down. The US Navy is developing the same technology for its next generation of aircraft carriers. After 50 years of using steam catapults, the Navy is testing various jets with the electromagnetic aircraft launch system and it's preparing to [unk] the first carrier to use the technology. Even tried and true wooden roller coasters are getting modern makeovers this year. Great America's Gold Striker was designed with computers, but constructed by [unk]. -It's got a 108-foot drop. You're gonna go 55 miles an hour. You can see one of these banks here is an 85-degree bank. These are features that are not common in wooden roller coasters. -This one may look old fashioned, but the roller coaster's speed, its safety, even though screams wouldn't be possible without technology. -The ride control system tracks everything that happens on the ride, watching all of the inputs, all the sensors for watching air pressure, locations of trains, sensing speeds, position of brakes. So, everything is being monitored and controlled in a redundant fashion. So, all riders have to worry about is having fun. In Vallejo, California, I'm Sumi Das CNET.com for CBS News.
This summer, amusement parks around the U.S. are opening roller coasters that are bigger, faster, and scarier than ever thanks in part to technology that will soon help launch jets off U.S. Navy carriers A similar electromagnetic technology, called LIM or linear induction motors, powers Six Flag Discovery Kingdom's Vertical Velocity ride. Check out the POV video.
When planning San Francisco's new California Academy of Sciences building in Golden Gate Park, engineers ran across a few design challenges that demanded clever solutions. CNET News.com's Kara Tsuboi explains how they borrowed ideas from other areas of engineering--from roller coasters to submarines--to solve those problems.
Wooden roller coasters are getting modern makeovers this summer with state-of-the-art designs that make some feel as smooth and fast as some steel coasters. On the new Gold Striker at California's Great America, riders are shot through zero-G camelbacks and extreme banking turns. Check out the POV video.
Pop Levi has led what one might describe as a melodic life. From childhood his life has been steeped in music. He took up piano at age 3, joined a gospel choir at 7, and started record collecting at 9 just prior to writing his first song. It was a precocious start for an artist who has proved to be a prodigious talent. This English born, LA based multi-instrumentalist was a founder member of avant-garde rock collective Super Numeri before embarking on a global roller coaster ride as bassist with electro pioneers Ladytron. All the while he?s been perfecting his modern spin on rock and soul, releasing two singles on the ?Trons Invicta Hi-Fi label', and carefully crafting his debut solo album. August 2006 sees the release of his first EP on Counter Records. Drawing inspiration from such luminaries as Van Dyke Parks, Jimi Hendrix, Marvin Gaye and Syd Barrett, Levi creates his own brand of gloriously funky alt-rock, meticulously piecing together his kaleidoscopic sound from recordings he?s compiled over a ten-year period. The roar of a motorcycle and the Bolan-esque swagger of title track Blue Honey, kicks off this five track EP. Track 2 (A Style Called) Crying Chic sees Levi pay tribute to the sun drenched sounds of 60's west coast America before he struts his stuff on the Zeppelin-heavy guitar riffs of Mournin Light. Penultimate song Baby Again (Midnight Version) has a looser, more experimental feel, prior to more close-vocal harmonising and finger clicking beats from Levi on an alternate recording of album track Skip Ghetto (Echo Park version). The album, The Return To Form Black Magick Party, described by Levi as a truly bizarre whirlwind of classic sounds has been mixed by Thom Monahan, Devendra Banhart's producer, and produced by Pop Levi himself. It is due for release in the New Year. Meanwhile Levi and his band have been astounding audiences with their soulful vocals and guitar pyrotechnics both at home and here in the UK and plan a return trip to the UK in August for a clutch of dates to be announced shortly.
At restaurants across the country, you may find a new hi-tech dinner companion at your table: a gadget to help you order, pay the bill or just keep you entertained. But will this technology revolutionize the dining experience or is it just an expensive gimmick? CNET's Kara Tsuboi reports.
