A Memory Card Torture Test
An anonymous reader writes "Would you buy a Ferrari and put regular gas into it? I don't think so. So why are most of us buying expensive digital cameras and using cheap memory cards? If you want to find out how much better a high speed memory card is, check out this group test of high capacity compact flash and SD cards."
Engines are metal, and under extreme pressure. Metal does not break, unless you hit it really hard, or heat it up a ton. Putting cheap or expensive gas through an engine does not break the engine. Aside from the parts that break intentionally, such as oil filters and brake pads (that wear out), a car should not break unless you crash it into something, hit it with a bomb, or possibly disassemble it with tools and then reassemble it incorrectly, in such a way that the awesome power generated by the fuel burning inside the engine damages the parts. Even running an engine with no oil in it to lubricate the moving parts and reduce friction will not break metal, it will simply reduce the power and efficiency of the engine. The same goes for the transmission. Metal does not wear out or break, at least not in our lifetimes. Ironically, I tried a variety of gasses in my motorbike, and there didn't appear to be any noticable difference between 85 (en mexico and arizona) and 91. Jet fuel works pretty good, if you have an engine that can withstand the extra heat and force. To get an idea of how powerful the fuel inside the engine is, try pushing a car by hand with the car in neutral...that's how strong the engine is, and how much force is on the parts inside it during normal usage. Of course, there's an easy way to break an engine on a manual transmission, overrev it and the force of the engine breaks itself...otherwise, they're pretty close to indestructable. (Not counting the soft outer paint, which is easily scratched, or the soft fuel tank that is mandatory and explodes.) A turbocharger (actually an air compressor) that injects extra air into the engine, along with fuel injectors that inject extra fuel at the same time does increase the power of the car...but why not just get a 440 stainless turbine engine and put jet fuel in it, then use a standard air intake that is much more effective at higher velocities? Last time I checked, jet airplane gas was $.30 per gallon at the airports. Plus, then you'll have a car that goes 0-600, and can spin the tires against the road at any speed up to ~500...or alternatively, a car that doesn't need refueling for 5000 miles with a bit less power. I assume that turbine engines aren't popular for the same reason metal, non-wearing-out brake pads aren't popular, too...there's only one moving part, they're more fuel efficient that the 4-stroke engine, they're silent when muffled, and easier to muffle, otherwise they're the same loudness as the 4-stroke, easy to manufacture due to the one part, and less prone to break (unless you rev the heck out of them, as always) than the fragile crankshafts and valve stems of the 4-stroke, and the clutch and rev style of the turbine is much more suited to the speed up and slow down style of the roads, since you can go faster on the straight parts of the road, then let the engine spin up while breaking for the turns, then clutch to convert the revs of the engine into rear-wheel power. Of course, a properly sized turbine has plenty of power without clutching, too.
