So even small weight savings - when multiplied by the thousands of parts on a typical vehicle - can up add to significant amounts. They have to be, in order to withstand the tremendous stresses and temperatures created by the force of thousands of controlled explosions per minute that take place beneath the hood. It takes the place of several other trucks. Before fire trucks or even fire wagons existed, the way to fight a fire was to use a human chain and a number of buckets in a bucket brigade. A number of car manufacturers, notably Lexus and BMW, are working to change that with intensive research into developing ways to reduce the cost of producing carbon fiber for vehicles. ­Creating bone china entails an involved series of steps carried out by a number of highly skilled individuals and some really impressive machinery. We could even find a good use for some of the estimated 2.5 million tons of plastic water bottles thrown away each year: The Hyundai QarmaQ concept, as an example, boasts a body made substantially out of recycled plastic water bottles. The company boasts that the cargo is the biggest ever moved by road in the Middle East, and that probably holds true for the world as well.



















Way: A small street branching off a road. Court: A street ending in a loop or a circle, aka a cul-de-sac. Place: A road or street with a dead end that`s not a loop or circle. Drive: A long road that winds around a geographical feature such as a river or mountain. Dry ice also has the very nice feature of sublimation - as it breaks down, it turns directly into carbon dioxide gas rather than a liquid. If you want to create an outdoor fire feature that has it all, think vertical and build an outdoor fireplace. The damage caused by a fire outbreak is irreplaceable. With no heat, they’ll have to use space heaters to keep warm after just going through a house fire. Fortunately, the engineers and scientists tasked with the goal of making automobiles more efficient have a few tricks left up their collective sleeve. Up until a few years ago, lead-based batteries were the juice supplier of choice for electric cars - largely because that was all that was readily available.



















That`s despite the steady growth in gizmos, safety features and creature comforts that have made our vehicles like rolling homes and offices over the years. This trend has actually been in progress for decades: The average sedan today weighs 3,000 pounds (1,361 kilograms), compared to 4,500 pounds (2,041 kilograms) 30 years ago. By 2025, it`s quite possible that the average passenger automobile will be capable of getting more than 50 miles per gallon (21.3 kilometers per liter) - if it runs on conventional fuel at all. Ugh, getting pulled over is the worst, but don`t panic if you hear an officer signal a "10-27." This is a way of communicating with dispatch to collect information about you based on your driver`s license details. By almost all accounts, the days of abundantly cheap gasoline are over. Head on over to the next page to read about the smart materials that are making car parts lighter. It may not be too far off that you see everyday production vehicles whose entire exterior bodies are made of plastic, skipping the aluminum or steel typically used for body panels. When sheets are soaked in a special resin, applied to a mold or form and allowed to cure, the resulting product can be as strong as steel, but at half the weight (and 30 percent lighter than aluminum).



















But here are some other common road definitions. Lane: A narrow road that typically leads to a residential zone. The trade-off for that durability is that traditional engines are extremely heavy - several hundred pounds in the case of a typical passenger automobile. How is a car builder supposed to "get the lead out," weight-wise, when vehicles rely on batteries (traditionally heavy lead acid ones) to supply a vehicle`s many electrical needs? Then along came nickel metal hydride (NiMH) batteries that were lighter and still capable of packing a powerful charge - and used widely in hybrid vehicles. These motors are then controlled by a computer that directs them to spin the wheels as needed. We chose the same x coordinate, a y coordinate 20 blocks higher and then successively larger z coordinates so the sand dropped in a line away from Steve. Chicago took things a step further by selecting the intersection of State Street and Madison Avenue in the heart of the city as its zero coordinates.
