IBM AGAIN
IBM is climbing back to the top of the big iron heap.
On Tuesday, the computing giant announced a deal to sell a new supercomputer--one that it says will be the most powerful in the world--to the U.S. Department of Energy (DOE). IBM (nyse: IBM - news - people ) boasts that its so-called Sequoia system will be capable of crunching numbers 20 times faster than IBM's last record-breaker and 15 times faster than the current fastest machine.
IBM has promised the DOE that the computer, part of its Blue Gene series and scheduled for delivery in 2011, will be capable of 20 petaflops, or 20 quadrillion floating operations per second. That's the equivalent of completing calculations in around eight hours that would take a typical Intel-powered (nasdaq: INTC - news - people ) laptop 20,000 years--or, by IBM's count, the ability to finish in one hour a series of computations that would require the entire population of the planet, armed with pocket calculators, 320 years to complete.
Like its predecessor, the one-petaflop Road Runner supercomputer, Sequoia will be offered for general use to the scientific community for several months before it's put to use modeling the deterioration of America's nuclear weapons stockpile. The DOE will house the computer in its Lawrence Livermore National Laboratory in Livermore, Calif.
The Sequoia announcement is IBM's answer to Cray's Jaguar supercomputer, which last November challenged IBM's lead in the supercomputing race using clusters of Advanced Micro Devices (nyse: AMD - news - people ) chips to achieve processing speeds of 1.6 petaflops, 60% faster than the IBM Road Runner supercomputer that broke the so-called "petaflop barrier" in June.
But Sequoia will do more than leap-frog Jaguar, says IDC analyst Earl Joseph. He argues that Sequoia could vastly outpace Moore's Law and set a new standard for supercomputing for years to come, much as Japanese company NEC's (nasdaq: NIPNY - news - people ) Earth Simulator remained the top-ranked supercomputer for much of the earlier part of the decade.
"This has created a bar much higher than we all expected," Joseph says. "If they had said 20 petaflops by 2015, that wouldn't have been a surprise. By 2011? That’s a real eye-opener."

Engines for Nitro Remote Control Cars
Engines for nitro remote control cars come in a variety of types, and it's important for you to distinguish among them and know what maintenance they require so that you can keep your nitro RC car in able shape for competitions or fun races with friends.
Most engines for nitro remote control cars are 2-stroke engines-- unlike the internal combustion engines for life-sized cars and lawn mowers, which are 4-stroke engines. Every cycle of an engine's piston involves two strokes; 4-stroke engines require the piston to make two cycles-- one to get rid burnt fuel and replace it with fresh fuel, and the other to power the car via the fourth stroke.
The 2-stroke engine, on the other hand, only needs one cycle of the piston to power the car. The first stroke is initiated by the explosion of the mixture of fuel and air, which forces the piston down. During the second stroke, the piston moves up, exerts pressure on the combustion chambers, triggering another explosion and repeating the cycle.
Most of the engines for nitro remote control cars that you'll find will last you long enough to go through one to ten gallons of fuel. If you frequently race nitro RC cars, you will need to replace your engines often. Though powerful, nitro RC engines are extremely small, ranging from 0.12 to 0.30 inches in size.
Older nitro RC car engines used to have their pistons encircled by rings, which enabled them to compress the fuel/air mixture in the same manner as a gas powered engine would. Today, however, you'll virtually always encounter ABC engines with no rings. Rather, the ABC engine has a tapered brass sleeve over the piston; the taper on the sleeve, combined with a thin oil film, makes it possible for the piston to compress the fuel.
The smaller engines for nitro powered RC cars are called small blocks; their size ranges between 0.12 and 0.18 inches, and they work best in 1/10th scale vehicles. Small blocks utilize crankshafts that are threaded all the way on the visible part in front of the engine. The larger big block engines use the SG crankshaft, which is only partially threaded in the middle.
If you own a nitro radio controlled car made by Traxxas, your engine will use a special crankshaft: the IPS or Integrated Pilot Shaft. The IPS has a special e-clip slot at the end to help you change the clutch bell more easily if you need to.
Another vital part in engines for nitro remote control cars is the cooling head-- made of aluminum. The cooling fins on the cooling head redirect heat from the engine to the outside air, but they require good ventilation to function properly. A hole in the nitro RC car's windshield-- right above the engine-- will help you give your nitro car the airflow it needs so the engine doesn't overheat. Also tune your engine regularly so that overheating becomes less likely.
If you want to minimize problems with your RC nitro car's engine, spend about as much time maintaining it as you do running the car; invest this time, and you'll have a reliable RC car which will give you back in thrill and enjoyment much more than the value of the labor you put into it.

NEw age CAR engines
In the last two years, carbon emissions have become an issue of contention for new and used car owners. Motorists are being encouraged by both politicians and the media to downsize their vehicles and reduce their carbon footprint.
There is even a strong suggestion that the London Congestion Zone will shift to incorporate vehicle emissions by the end of the year, making it more a low carbon zone than a congestion zone.
Some manufacturers including Saab, think that bio powered or Flex-Fuel cars (ie. Cars which can run on emissions free E85 ethanol or petrol or a combination of the two) are the solution. However, the infrastructure required to set up ethanol filling station pumps, let alone ethanol refineries on a national scale is at least ten years away.Instead, we must embrace the more obvious but mass scale breakthroughs that are happening today. No car manufacturer has been so readily willing to change as BMW.
It's 'efficient dynamics' programme has re-engineered its cars at a phenomenal rate from engine tuning to incorporating regenerative braking technology throughout the range.
The Mini Cooper Diesel is now the cleanest car BMW has ever built, having a combined fuel consumption figure of 64mpg and emitting just 104g/km of carbon dioxide emissions - tailpipe emissions that were unfeasible three years ago. These emissions savings even extend to the 5-series saloon where the 2.0-litre diesel version emits just 136g/km - about the same amount as a hatchback.
Simultaneously, Mercedes released the E 320 BLUETEC in the States. It became the first diesel engine to pass California's stringent vehicle emissions tests, achieved by developing a urea injection system (yep, that's basically wee) to pump a small amount of ammonia-based acid into the exhaust stream, neutralizing the harmful emissions. As a result, it was voted "World Green Car of the Year 2007" and now, it's heading to the UK.
But In the future, Mercedes Benz reckons we will adopt DiesOtto technology, which basically fuses the talents of both petrol and diesel engines together. This technology was unveiled in the shape of the F700 Concept and a compact four-cylinder turbocharged engine with unparalleled power, torque and flexibility. Ignore the fact that the F700 is more than five metres in length, but that it's a luxury performance saloon that has the same economy and emissions as a diesel supermini.
