Capturing Pressure for a Greener Future At this very moment, the amount of cars driving on roads or highways would seem to be an uncountable number. In reality, according to Statistic Brain, the number of cars being manufactured in the world exceeds 48,039,060. This number is not counting commercial vehicles, and due to the high demand for commercial vehicles for today’s businesses, the number can be assumed to be much higher.
The typical car will release an exorbitant amount of CO2, which to certain people has become too much of a problem to ignore. To counter this growing pollution problem and the eventual collapse of our atmosphere, humanity created Smart Cars. These Smart Cars replace the use of fossil fuels, as well as severely reduce the amount of CO2 emissions. However, even as these cars seem to bring about a change for the better, most people forget the cost of

When pressure is applied to the piezoelectric plates a negative charge is then produced on the “expanded” side while a positive charge is produced on the “compressed” side. Once the pressure stops compressing the plates, the electrical current flows again across the material. Electro-mechanical sensors will be placed inside popular areas and stretches of road. When cars pass over these sensors they depress the plates and the kinetic energy lost by slowing down is passed from the car into the plates.
A popular example is walking and foot pressure. If you use the motion of walking instead of driving, a single footstep would cause pressure to be applied to the plates when stepping on these piezoelectric plates; the charge that is produced is captured by sensors in the floor. This charge is then converted to an electrical charge by piezo material, usually in the form of crystal or ceramics. This electrical energy is then stored and used as a power source. One footstep can make enough energy to light two 60-watt bulbs for one
Increasing environmental awareness, coupled with a responsible American government and improved technology, have all contributed to the comeback of low-and zero-emissions vehicles in the US. It remains to be seen whether the automakers and oil companies will once again work to halt this progress, or embrace it as the technology of a more responsible future.
The majority of people, especially in America, cannot go about their daily lives without a car. Automobiles have instilled themselves in peoples’ lives and shown their usefulness since their debut in 1769. Since then, humans have redesigned and refined the automobile thousands of times, each time making the vehicle more efficient and economical than before. Now as the world approaches an ethical decision to dwarf all others, many people look toward automotives for yet another change. The emergence of the hypercar due to ecological turmoil exemplifies the change the world has demanded. Hypercars alter everything people know about automotives, modern ecology, and fuel efficiency. Not only do hypercars offer a solution to many ecological problems humans are faced with now, they also represent the only logical area for the automotive industry, and by some stretch American society, to expand.
Self-driving cars are now hitting a few roadways in America, and are showing people just a small glimpse into what could be the future of automobiles. Although Google’s self-driving cars are getting a lot of attention now, the idea of a self-driving car has been around for quite a while actually. These cars have been tested to their limits, but the American people have yet to adopt the technology into their everyday lives. A brief description of their history, how they work, and finally answer the question, will self-driving cars ever be adopted widely by the American public?
Google Chauffeur alerts human driver about situations where the human needs to drive, like a toll booth or merge (Pollette).
Imagine having your life flash before your eyes while you were still wearing diapers. And imagine having a hot hunk of metal crash into you and shatter your sense of everything. When I was just three years old, I was the victim of a very scary car accident. While waiting to make a turn into my nursery school, my mom’s car was rear-ended by a car driving at 50 miles per hour. I remember how incredibly loud the collision was and even how the windows seemed to shiver in their rubber holders. Seeing my mom's head fly back and feeling the car swerve into the opposing traffic, I thought I was going to die. And why did this happen? Because the person driving behind us was texting on her phone and was not focused on the road. All of this, the emotional, physical, and financial damage, and the possibility of losing my mom's or my own life, could have been prevented if the car behind us was a driverless car. Briefly, a driverless car is capable of driving itself via an intricate system of cameras, sensors and computers. I propose that human drivers should be replaced with driverless cars because driverless cars are safer and more efficient.
Imagine that you’re driving on an open highway in the middle of summer. All you see in front of you is asphalt for miles and miles. The windows are down and your favorite song comes on the radio. You’re behind the wheel of a Tesla Model S, the newest electric car that can go from zero to sixty miles per hour in 2.4 seconds. This will soon be the future of all motor vehicles. Electric cars are beginning to have colossal impacts on our society because of their energy efficiency, performance benefits, and the fact that they are less harmful to the environment. In the near future, electric cars will dominate the road and eventually the planet’s overall need for oil will decrease immensely.
Purchasing a car is one of the hugest or biggest accomplishments that a person can achieve on their own. However, what happens when that purchase turns out to also be the worst decision that was ever made? The purchase was a success and a goal was achieved, but the moment the key is turned and the engine is started the contribution to environmental harm begins. As the car is driven, the gasoline fumes that are released from the car contribute to the other many factors and pollutants that damage the environment. Not only is the purchase now a contributor to the depletion of clean air, but it could also play a part in the depletion of someone’s health. For example, asthma or bronchitis could develop in an adult or child as a direct result of breathing in noxious automotive fumes. Depending on where one lives, there could be strict regulations on air pollution. One must be accountable for any and all contributions made to the demise of what was once a healthy Earth. One must be accountable for his or her own carbon footprint. Some individuals have taken steps to reduce their carbon footprints and cause less harm to the environment by purchasing electric cars.
Self-driving cars are the wave of the future. There is much debate regarding the impact a self-driving car will have on our society and economy. Some experts believe fully autonomous vehicles will be on the road in the next 5-10 years (Anderson). This means a vehicle will be able to drive on the road without a driver or any passengers. Like any groundbreaking technology, there is a fear of the unforeseen problems. Therefore, there will need to be extensive testing before anyone can feel safe with a vehicle of this style on the road. It will also take time for this type of technology to become financially accessible to the masses, but again alike any technology with time it should be possible. Once the safety concern has been fully addressed
You are sitting in the backseat of your driverless car without a care in the world, watching netflix and enjoying your favorite assortment of snacks and beverages. All of a sudden your car goes from the speed limit to full throttle in one jolt and take off down the freeway. The car is not designed to go this fast and the other cars do not have time to react. Is this really what you want in a truly driverless car, having no control over the situation and putting your life in the hands of autonomic machine? Driverless cars should not be introduced to the common public because of deadly errors in the cars system, problems with the laws and regulations, and the role humans play in these cars.
Application of an electric field across the ceramic creates a mechanical strain, and in a similar manner, application of a mechanical stress on the ceramic induces an electrical charge [4]. The fundamental component of a piezoelectric stack actuator is a wafer of piezoelectric material sandwiched between two electrodes. Prior to fabrication, the wafer is polarized uniaxially along its thickness, and thus exhibits significant piezoelectric effect in this direction only. A typical piezoelectric stack actuator is formed by assembling several of the wafer elements in series mechanically and connecting the electrodes so that the wafers are in parallel electrically, as illustrated in figure 5 [4]. The nominal quasi-static behaviour of a piezoelectric stack actuator is a steady-state output displacement that is monotonically related to the voltage
Often, people say that to drive, you need both hands on the steering wheel . They also say that you should not use your cell phone when you’re driving. That’s ending right now!!!
Today, people use their own personal vehicles to travel more than ever before. Personal transportation is no longer considered a luxury; it is now considered a necessity. The number of cars in the United States has been growing steadily since the 1970s. The number of miles traveled by cars has risen nearly 150 percent, yet the United States population has only grown roughly 40 percent during that time (hybridcars.com, Driving Trends). Although it may seem like we are advancing into the future, in reality, we are moving backwards from the effects these vehicles have on our bodies and the environment. The pollution produced by these vehicles has brought us to the day where we must find other modes of transportation that cause less harm to the world in which we live. Advances in technology have developed hybrid vehicles to try and slow down the amount of pollution. Driving a hybrid vehicle, instead of a conventional gas powered vehicle, can reduce the amount of pollution that affects our lives and the environment around us.
Autonomous cars, they are an extraordinary move in the vehicle industry! For those who do not know what autonomous cars are, they are cars that drive themself, cars that have an autopilot feature. Autonomous cars are cars of the future, there are very few as of today. One of the first are made by the Tesla company.
Hybrid cars and trucks are beginning to become very popular in our day of time. The inventor and the founder of the hybrid car was Robert Anderson. Anderson was born in Aberdeen, Scotland. He invented the vehicle in 1839. The hybrid vehicles get better gas mileage than most of the older cars and trucks. Most of the new vehicles that are being made today are some sort of hybrid or ecoboost vehicle. Almost all of your car manufacturers today are trying to create new vehicles that conserve gas which is green to the environment. Gas efficient cars are now taking over diesel car and trucks. Diesel cars and trucks usually get pretty bad gas mileage. Most of the big older trucks have a diesel engine in them. Most of the owners of a diesel vehicle usually don’t drive the vehicle much anymore because of horrible gas and diesel prices this day in time.
The fast population growth rate of humans means that the necessity for transportation vehicles is also enormously increasing. Studies have shown that in 1999 the worldwide number of vehicles registered was 700 million. From this huge number of vehicles, the US has a large share, which includes 200 million cars and light trucks. The number of cars worldwide also grew three times faster
