Earthships

­­­­­What is an earthship?

An earthshi­­­p is a home designed to make use of recycled materials and increase energy conservation. Ideally, by living in an earthship, a person can have a home that is “off the grid.” People who live in earthships do not depend on outside sources for electricity, food, or water. Building an earthship may be an attractive choice for those who want to use fewer of our planet’s non-renewable resources.

The Foundation

First, the foundation is built by firmly packing dirt inside recycled tires. Then, the tires are placed in a pyramid-like stack going as high as needed. Next, cement is spread and smoothed between the tires to create a solid wall. When this is finished, the walls are sealed with a protective coating and painted. Some interior walls are built using recycled cans and cement, also sealed with a protective coating.

Solar Energy

Solar panels give enough stored energy in batteries to provide electricity for appliances, lighting, and electronics. However, solar-powered batteries hold about one-third the charge of energy used in a regular household wired for electricity. This means that people either buy more batteries or intend to use less electricity than a conventional household. Ideally, earthships are built in places where there is an abundance of sunshine year-round.

Floor-to-ceiling windows on an earthship’s south wall also allow plenty of sunlight. It is important that no trees block the light on this side of the house. The sunlight shines directly onto a brick floor, which then absorbs the heat. This provides enough warmth to maintain a comfortable temperature in the house for the rest of the day. This method of heating the home is called passive solar. Most earthships also have either a wood stove or a heater that uses propane, a type of natural gas. These heat sources are useful on cloudy days. During the summer, the combination of the cool temperature of the earth beneath the floor plus the thick walls can keep the house comfortable without the use of air-conditioning.

Recycled Water

Gutters on the roof collect rainwater that then trickles down into large storage barrels. The water is used for taking showers, doing dishes, and flushing the toilet. It is also filtered for drinking. People sometimes build a greenhouse to grow their own food. Water that has been used for dishwashing or showers can be saved if the soaps are chemical-free. This recycled “gray” water can be used yet again to water the plants in the greenhouse.

Potential Problems

Earthships have been around since the 1970s. Now, ­­long-term studies have revealed some problems. For one, without sufficient sunlight during the winter, large amounts of natural gas known as propane and/or wood are used to heat the home. Propane use can be costly, and unless one has planned far ahead, a wood supply can be quickly depleted.

Another problem is that tires used in the foundation walls can, after a long period of time, begin to crack, releasing a toxic gas that has built up over time in the walls. The use of cement, which is a porous material with many small holes and spaces, allows the gases to leak into the air. The type of gas emitted is not detectable by smell but can make people sick. To address this problem, the walls of the home needs to be resealed every year.

Cost can also be a significant challenge. Some earthship building companies claim that it is far cheaper to build an earthship because only recycled materials are used. Also, a contractor’s license or training is not needed to build one. This, though, is true if it is built 100% by the owner, which could take years to complete. Additionally, the cement, plumbing, and electrical components, as well as the cost of installing solar panels, can be expensive. Just as with the construction of a conventional home, proper permits are often needed to build an earthship.

There are clear advantages and disadvantages to these unique homes. As technology improves and new solutions are discovered, earthships may continue to be a wise way to live sustainably using minimal resources.

In the U.S., teenagers are considered adults when they reach the age of 18. At 18, they are allowed to serve in the military, they are allowed to sign legal contracts (like apartment, house, and car leases), and they are allowed to vote. All of these activities are important; however, one of the most important is left out. The driving age in many states is 16. Is driving less important than serving in the military? Federal law should require that teenagers should not be allowed to drive until they are 18.

One reason that the driving age should be raised to 18 is because 16-year-olds have a different set of responsibilities than 18-year-olds. For example, many 16-year-olds have only just entered high school. Some high schools offer early graduation for students who do well academically. This should be their first priority—school. Many high school kids are too distracted by the thought of a driver's license to study. This shows the type of drivers they will be—distracted. Do people really want a 16-year-old who can't even concentrate on studying distracted and behind the wheel of a two-ton car? A 2005 study of cell phone users shows that many use their cell phones while they drive.

Another reason the driving age should be raised is because it will make kids more responsible. By the age of 18, many students are starting to grow into adults. Many have jobs. Many will graduate. Many will start to plan for college. This is exactly what it is like to be an adult—having responsibility. A teenager turning 18 will be more likely to take his or her driving habits seriously because it would be one of many other adult responsibilities they would have.

Finally, at the age of 18, the government can hold teenagers accountable as adults. This would make things safer for all drivers. Teenagers behind the wheel of a car cause more accidents than adult drivers. Each year, S.U.V.s are involved in more accidents than regular cars. In an accident where someone is injured, the person responsible for the accident can be punished by the government. This isn't the case if the person responsible is 16. Laws apply differently to adults than they do to teens. Many times, the parents are responsible. If a driver had to wait until he or she were 18 to drive, he or she would be the only person to blame in an accident. This means that the 18-year-old would be punished by the same law that punishes adults. The same driver at 16 would not be held to the same punishment since he or she is considered underage. This is clearly not fair.
8
Which sentence supports the idea that teenagers behind the wheel of a car cause more accidents than adult drivers?
A.
For example, if an 18-year-old had the choice, he or she would rather drive faster than slower when on the freeway.
B.
The demands of being a teenager, going to school, getting good grades, finding one's self, and planning out the future are stressful.
C.
An 18 year old is considered an adult; however, in many states, this does not mean he or she can drink legally since that legal age is 21.
D.
For example, the U.S. Department of Transportation says that in 2004 60% of the accidents in the U.S. involved drivers younger than 18.
