How Inflation Can Save You Money

Many Americans suffering from sticker shock at the gas pump could get an additional 10 miles out of every fill-up. In fact, American motorists could save more than $1.1 billion in unnecessary fuel costs. One of the fastest, easiest and least expensive ways to improve a vehicle's gas mileage is through proper tire inflation. An underinflated tire doesn't roll as smoothly and the increased resistance requires more energy, robbing the vehicle of fuel efficiency. Yet one in every three cars in the U.S. has at least one underinflated tire, according to the National Highway Traffic Safety Administration. Underinflated tires cost the country more than 3.5 million gallons of gasoline each day. The average driver could improve gas mileage by 3.3 percent by simply keeping tires inflated to the proper pressure. For the average 15-gallon fuel tank, U.S. Department of Energy (DOE) statistics suggest, that's a savings of about $1.50 on every fill-up. To help, the experts at The Goodyear Tire & Rubber Company have developed a few more easy gas-saving tips: • Replacing a clogged air filter can improve mileage by as much as 10 percent. • Don't overload your car. An extra 100 pounds reduces fuel economy by 1 or 2 percent, says the DOE. • Use the grade of motor oil recommended by the vehicle manufacturer. That can improve gas mileage by a percent or two, the DOE adds. • Keep your car properly tuned. That can improve gas mileage an average of 4.1 percent. • Make sure your gas cap is on tight and not damaged. Some 17 percent of the vehicles on U.S. highways have either misused or missing gas caps, causing 147,000,000 gallons of gas a year to vaporize into the atmosphere, reports Service Tech Magazine. • Avoid quick or "jackrabbit" starts and stops. Aggressive driving wastes gas and can reduce your gas mileage by 33 percent on the highway and 5 percent in the city. Observe the speed limit; gas mileage decreases rapidly above 60 miles per hour. • To maximize fuel economy and also improve tire performance and efficiency, Goodyear is offering free inspection of tires-regardless of brand-at any of its 750 company-owned and at participating independently owned and operated Goodyear locations across the country. If tires are underinflated, they will be filled at no charge. No appointment is necessary.

How I spent my Vacation in Amsterdam

During the vacation I got to see many of the wonders that Amsterdam has to offer. One of the first things I went to see was the Van Gogh Museum. Having just gotten off the plane I was tired, but some of his art is just amazing to see, and I did not want to wait to see them. After going to the museum I headed into the city center to look around, maybe do some shopping and get some food. I had herd many things about Amsterdam and just thought that many of them were blow out of proportion, well I am here to tell you that they are all true. The first thing that hits you is the strong smell of Marijuana, and then you start to see the almost completely naked girls in the windows. As if the prostitutes in the windows were not enough there are live sex shows and sex shops selling every imaginable sex toy known to man on every street, but this was not what interested me. Then as I continued walking around I started to notice something besides pot, and naked females, I saw casinos. I grew up in New Jersey, just about 2 hours from Atlantic City, and after my 18th birthday I spend a good amount of time in the casinos. So I decided to go in and check some of them out. Well I wound up spending most of the rest of my time in those casinos. The first one I went to was Video Gaming machines only, but they had video poker, video blackjack and Video Slot machines as well, I did not really do well her in this place so I only spent about an hour, and about 100 Euro, then left. The next place I found was a nicer place. Unlike in New Jersey, in these casinos people are dressed up in their nice clothes instead of jeans, sneakers and T-Shirts. This casino had actual table games so I tried to play some Blackjack, but there was a player at the table that either had no idea on how to play or he was somehow involved in cheating with another player, but I am inclined to think he just did not know how to play blackjack. So I started playing at the Roulette table, and I was doing really well, at one point I was up about 400 Euro before I started losing. So I decided to leave this casino and go walking around for a while. The next day I found myself in another casino, and I decided to see if my luck was back, I went to a slot machine and put in some money and on the third spin I won another 200 Euro, so feeling lucky I decided to enter the poker room, and that is when things got really interesting. I got into a game and boy were these guys good, but I was winning just as much as I was losing, and in the end I may have even walked away with a few Euros more then when I walked in. After playing for about 5 hours I decided to go outside and walk around a bit to stretch my legs. I would up deciding to sit down and have a cup of coffee, but I did not know the difference between a coffee shop and a caf?. In Amsterdam a caf? is a place to sit and have a coffee, but a coffee shop is a place to purchase and smoke Marijuana. So as I was sitting there drinking my coffee I noticed several people rolling joints. Now I have herd about this and I hade smelled plenty of pot while I was there, but I did not realize it was sold out in the open like this. So I decided to buy some pot and try it. I went to the counter where I saw others buying their weed and the guy behind the counter was very nice and showed me a menu of what they had for sale. I wound up buying a joint of white widow. The man behind the counter told me his was very strong stuff, but I was not prepared for this. I managed to smoke about half of the joint, before I was hit with this feeling. I have been a drinker for many years, but even in my college days I was never out of my head like this. Eventually I managed to get out of there and get some fresh air, and some waffles. I decided, this was the time to back into the casino and win my money back, and in the end I lost another 600 Euro, and wound up falling off my chair in the casino and needed to be helped out. So if you are going to be going to Amsterdam, be careful the grass is really strong.

How Hybrid Cars Work

A hybrid car is such a car in which two types of motors are synchronized to provide power to the wheels. The most popular combination is the one in which the gasoline engine is assisted by the electric motor so that the gas engine is periodically shut off in order to reserve fuel. Usually hybrid cars are subdivided into two major categories. In the first type, only the use of electric motor propels the engine at very low speeds. The electric motor has the inherent ability to assist the engine when more power is required. It helps out the gasoline engine even while climbing or passing a steep road. The Ford Escape Hybrid and the Toyota Prius fall into the initial category. The second of its kind requires extra horsepower for its gasoline engine to drive while in rapid acceleration or when moving up the hill. It utilizes that excess power only from the electric motor to assist the internal combustion engine. The Honda Insight and Civic Hybrid are ideal examples of the second category. These two engines do possess some resemblances as well. When electric motor is used to assist the gasoline engine, both of the hybrids extract power from the battery depleting power, which in turn gets simultaneously self-recharged from the gasoline engine. Hence a hybrid car does not need to be plugged into a power source to recharge its battery, which is the most important aspect of hybrid cars. Hybrid cars usually utilize sealed nickel metal hydride batteries, a technology which is popularly used in laptops and cell phones. These batteries are easy to make, cost effective and long lasting thus making it ideal for a higher valued car. Hybrid engineers more than often have opted for unconventional design facets to maximize aerodynamics inside the engine, giving rise to its slim structure. These car units originally have very low (ultra low) drag coefficient due to sleek configurations, which make the cars slippery. All carmakers strive to reduce drag, as a vehicle with less drag requires less power as well as fuel to move. The electrical system is monitored by an onboard computer system. The system is program controlled in such a way that when the vehicle is coasting downhill or the brakes are applied, polarity of the system is automatically reversed as the motor actually turns into an energy generating unit. This process is popularly known as regenerative where the conversion of mechanical energy to electrical energy stores up power into the battery. All hybrid cars normally shut the gasoline engine off during road signals so as to conserve fuel reserve. The phenomenon is called idle stop characteristics. It cuts electrical consumption down during idle condition other than fuel saving and emission reduction. On pressing the accelerator paddle, the gasoline engine resumes work getting assistance from electric motor. The process being silent and seamless, the loss or delay in overall performance during this time is almost negligible. The hybrids are manufactured by a special forging process termed as shot peeing, which reduces friction in the sidewalls of the cylinder thus increasing efficiency. Hybrid cars, thus, by virtue of their technological advancement, exceptional fuel economy and marginal gas emissions, can be easily termed as the next generation cars

How Horoscopes Help you Win

Many people believe that by using astrology you can tell your future, and maybe it can not, but by following the advice given in Horoscopes many people find great luck, so how else can it be explained. This phenomenon can be explained by the fact that if you believe it is true that you will have good luck on a certain day you probably will. This does not mean that the prediction was right, but if you believe good things are going to happen to you at work, in your personal life or in a casino, you will give off a positive energy that attracts other positive energies and this will help good things happen. Some people do not believe this theory either. They feel that if you believe good things are going to happen and they do it is because you were in a better mood and making better decisions which will bring about better results. No one can tell how exactly gambling horoscopes help a person win in a casino, but the fact remains that they do help people win all the time. Studies have been done to try to show exactly how horoscopes work, but no one has ever been able to come up with an explanation that seems believable. All they have been able to show is that the more you believe the better and more accurate the predictions will be. This may be because if you really believe in the accuracy of the gambling Horoscope you will find things that you rationalize to make fit into the horoscopes prediction. No one has ever been able to find any reason any form of prognosticating works, but people do believe in it and it is that belief in it that seems to make the things come true. Studies have been done in the past and have proven beyond doubt that a person who has a more positive outlook will tend to have better luck and will generally be a happier person; where as a person with a negative outlook will constantly have negative events take place around them. The only explanation scientists have ever given for this is to say that the average human only uses 10% of the brain and that the explanation for these events is hidden in the 90% of the brain we do not use, and that maybe if and when we learn the secrete for unlocking these areas of the brain we will then be able to get a better understanding of how all types of psychic predictions work. But until then all I can tell you is that if you believe that the prediction will come true then it will come true. By reading your horoscope and waiting until it says you will have a good day, then going to the casino to do some gambling you will greatly increase your chances of having a winning day and the more you believe it will happen the more it increases your chances of being successful.

How dynamometers work

Dynamometers or dyno systems seem complicated but once you understand the basics it all becomes clear! A dynamometer is basically just a measuring tool, in the same way as voltmeters, scales or speedometers are. Among force-measuring devices, dynamometers are a flexible metallic ring that bends when a force is applied in such a manner as to tend to collapse it (the amount of bending being a measure of the applied force) and a hydraulic “load cell” that measures compressive loads in terms of fluid pressure. Once you have built your new motor, or fitted any tuning parts, it is very important to visit a good automotive Dynamometer or rolling road. If you don't, then you will never be able to properly set up your engine. A good dynamometer allows you to use a gas analyzer while under load so you can see the real air fuel mixture at all RPM's while driving. Power-measuring dynamometers may be either transmission dynamometers or absorption dynamometers. The former utilize devices that measure torque, in terms of the elastic twist of the shaft or of a special torquemeter inserted between some sections of the shaft. The torque is produced by the useful load that the prime mover, motor, or machine is carrying. Unlike transmission dynos, absorption dynamometers produce the torque that they measure by creating a constant restraint to the turning of a shaft, by applying mechanical friction, fluid friction, or electromagnetic induction. A Prony brake develops mechanical friction on the edges of a rotating pulley by the means of a few brake blocks that are squeezed against the wheel by tightening the bolts until the friction torque FR balances the torque WL. A water brake creates a resistance by circulating the water flow between a rotating impeller and a stationary shell, while an electric dynamometer generates and absorbs direct-current electricity or eddy currents. In each case, the element that exerts the restraining influence is freely cradled so that its tendency to rotate with the rotating body can be restricted and the restricted force is measured at a known distance from the axis of rotation. Torque is the product of the spring load or weight and the distance from the axis of rotation. Dynamometers also measure the torque produced by an engine in order to reveal important information about its performance. A diagnose is then presented in performance graphs, which can be easily printed and interpreted.

How Does A Turbojet Engine Work?

A turbojet engine is a type of internal combustion engine often used to propel aircraft. Air is drawn into the rotating compressor via the intake and is compressed to a higher pressure before entering the combustion chamber. Fuel is mixed with the compressed air and ignited by a small flame in the eddy of a flame holder. This combustion technique significantly raises the temperature of the gas. Hot combustion chemicals leaving the combustor expand through the turbine, where power is drawn to employ the compressor. Although this expansion process reduces both the gas temperature and pressure at exit from the turbine, both variabels are for the most part still well above ambient conditions. The gas stream exiting the turbine expands to ambient pressure through the propelling nozzle, causing a high velocity jet in the exhaust plume. So if the jet velocity surpasses the aircraft flight speed it amazingly creates a forward thrust. Under normal circumstances, the pumping action of the compressor prevents any backflow, this kindly helps the flow of the jet engine. You can compare the whole method with a four stroke cycle, but with induction, compression, ignition, expansion and exhaust taking place simultaneously. The efficiency of a jet engine is strongly dependent upon the pressure ratio (Combustor Entry Pressure/Intake Delivery Pressure) and the Turbine Inlet Temperature of the cycle. It is also perhaps instructive to compare turbojet engines with propeller engines. Turbojet engines take a rather small mass of air and accelerate it by a large amount, whereas a propeller takes a large mass of air and accelerates it by a small amount. At great speed the exhaust of a jet engine makes it efficient at high speeds (particularly supersonic speeds) and high altitudes. On planes that go slower and fly a shorter range, a gas turbine-powered propeller engine, commonly known as a turboprop, is far more common and also more efficient. Especially small aircraft primarily use conventional piston engines to drive a propeller but small turboprops are getting smaller as technology improves each day. The turbojet mentioned above is a single spool design, where a single shaft connects the compressor to the turbine Higher Overall Pressure Ratio designs often have two concentric shafts, this is to in essence improve the stability of the compressor during engine throttle movements. Basically it's the outer shaft that connects the turbine engine to the high pressure compressor. The combustor together with the high pressure compressor spool forms the core or gas generator of the engine. We must not forget that the inner shaft connects the low pressure compressor to the LP Turbine to create the LP Spool. Either spools are free to operate at their optimum shaft speed.

How Do They Make Auto Glass Bulletproof?

As you may know bulletproof glass is glass that is capable of stopping all sorts of bullets fired at it. This type of glass is made by using a strong but transparent material such as polycarbonate thermoplastic. Sometimes it’s constructed by using layers of laminated glass. The polycarbonate layer is often put between layers of regular glass. A bullet will probably pierce the exterior glass layer, but will be stopped by the really strong polycarbonate layer before it can pierce the inner layer of glass. There’s also what’s called bullet resistant glass that’s constructed of laminated glass layers. This is built from sheets of glass glued together using some sort of liquid rubber. One-way Bullet Proof Glass As technology advances in the field of bullet resistant glass we now have a new type of bullet proof glass called one-way bulletproof glass. These types of glasses are commonly used by armored cars. The beauty of this glass is that it will resist incoming fire arms striking the outside of the glass, while allowing those on the other side of the glass, such as guards, fire from inside the armored car, through the glass at the exterior threat outside. Usually One-way bulletproof glass is made up of two layers. A brittle layer on the outside and a flexible layer on the inside. If a bullet is fired from the outside it will hit the brittle layer first and will probably shatter an area of it. This shattering of the glass absorbs some of the bullet's energy, and spreads it out on a larger area. When the slowed down bullet hits the flexible layer, it will be stopped. However, when someone fires a bullet from the inside it hits the flexible layer first. The bullet will then go through the flexible layer because its energy is focused on a smaller area. The brittle layer will then shatter outward because the inner layer flexes and doesn’t stop the bullet's progress.
