When your alternator is on its way out, you may start to lose power to your various electrical components when your car is at idle. And when they do burn out, pull out your owner's manual and replace them. You can squeeze out a few more miles. Directional drilling allows oil platforms to sink production wells into the ocean floor at an angle in order to reach deposits miles away from the drill site. Since production wells often have to sink miles into the Earth's crust, the drill itself consists mostly of multiple 30-foot (9.1-meter) drill pipes screwed together, called a drill string. When close to the surface, certain rocks affect the Earth's normal magnetic field. Since oceans cover nearly three-quarters of Earth's surface, a great deal of oil and natural gas reserves are located underwater. To meet our ravenous demand for fossil fuels, petroleum companies have invested billions into the development of offshore drilling operations and are constantly combing the planet for new reserves. If you are willing to manage your power a bit and make sure they do not all turn on at once, then your surge power requirement is only 2,400 watts. In addition, your generator will be trying to power the entire neighborhood, and it obviously cannot do that.

If you've seen the 2007 film "There Will Be Blood," then you may know this as the "I drink your milkshake!" method. That's right: there are ways to transmit power - and charge devices - without cables. Today's oil rigs are truly gigantic structures. In an effort to sustain our fossil fuel dependency, humans have built some of the largest floating structures on Earth. How do you tunnel into the Earth without water flowing into the hole or all the oil surging up into the sea? Of these two methods, air guns are far less of a threat to sea life, but even acoustic pollution poses a threat to such seismically aware sea animals as the endangered blue whale. The platforms are typically fixed directly to the ocean floor using either metal and concrete foundations or tethering cables. While the design may vary depending on the exact ocean floor conditions, the drilling template basically resembles a large metal box with holes in it to mark the site of each production well. This method, known as sparking, involves sending shock waves down through the water and into the ocean floor.

Well, it's time to mark down the GPS coordinates, plant a buoy and obtain a government lease to begin a little exploratory drilling and see what you've got. Throughout this process, a device called a packer travels down the well, expanding against the walls to ensure everything is sealed. One platform can boast as many as 80 wells, though not all of them go straight down. The system's disadvantages are that the line of sight between a camera and an LED can be obscured, interfering with the tracking process. Grounding directs electrical energy into the earth by providing a conductor that is less resistant than you are. A turntable on the platform rotates the drill string and, at the other end, a drill bit grinds through the Earth. With the aid of computers, seismologists can then analyze the information to pinpoint possible traps in the Earth. Surveyors can also detect possible traps through the use of seismic surveying. But as this method can only help find seeping deposits, oil companies largely depend on two other means of locating traps. To handle this job, oil companies send out a mobile drilling unit to perform exploratory drilling on a site.

In the years to follow, oil prospectors pushed out into the ocean, first on piers and then on artificial islands. For instance, in ­California, the state can seek permission to drill new oil wells in state waters if it can prove that wells in adjacent federal waters are draining California-owned oil deposits. If things are looking bad -- again -- the car will, with its last electronic breath, communicate with the dealership rather than your brother-in-law. Several news articles have suggested that fire and rescue crews face a serious chance of being electrocuted if they cut into the wires of an electric car, or that they might be electrocuted just from touching such a car if it is partially or fully submerged in water. So, now we know that electric cars are safe in an emergency situation if some basic precautions are taken. Certain parts of a car are inherently rigid and resistant to deforming, such as the passenger compartment and the engine. Probably the most widely known incident is the death of Dale Earnhardt Sr. in the 2001 Daytona 500. The crash didn't initially appear to be severe, and the car didn't seem to suffer extensive damage; however, that was exactly the problem.
