Not only does the use of plastic water bottles hurt your wallet, it also increases pollution and wastes energy and water. Only 23% of all plastic in America ends up in a recycling bin, meaning over $ 1 billion worth of plastic is treated as rubbish a year. Recently, Skipping Rocks Lab has invented a kind of water bottle called Ooho.

It is a convenient, clear water bottle that can either be drunken or eaten. To drink it, you can either peel off the membrane (薄膜) or tear a hole in the membrane with your teeth to pour the water into your mouth. To eat it, you simply put the whole bottle in your mouth. One problem the scientists have run into is how to ship large amounts of Ooho bubbles(水泡) without arriving with a very wet truck. However, they have attempted to package units of individual bubbles together inside a larger and thicker membrane. It is targeting large outdoor events, such as marathons, music festivals, and sporting events, where tons of plastic bottles are used, and frequently left behind as litter. And too much plastic is sure to do harm to the environment, which could account for their purpose of such a new invention.

The team has been working for the past two years to develop the technology and materials needed to produce Ooho; they have recently applied a patent for their new advancements. The price for an individual bubble or a unit of bubbles has not been set yet, but they cost about two cents to create a unit, which is cheaper than plastic bottles. It has appeared at events in London, San Francisco, Boston, at conferences, festivals, and so on.

Ooho is catching many people’s attention and has raised over $ 1 million and gained 1,000 investors in only three days. It is mostly being sold at events at the moment to keep the consumer’s interest while the production machine is getting up and running. It is quickly making a rise,so keep an eye out this year for these bottles of the future.

Buildings with windows filled with water could save energy greatly, according to researchers backing the new technology.

Traditional glass windows increase the heat and temperature in the room in summers, and let the heat inside escape in winters, resulting in more electricity consumed for air-conditioners and more carbon emissions (排放). Now, researchers at Loughborough University (UK) have created a water-filled window that can overcome these problems.

The “water-filled glass” (WFG) system, designed by Dr. Matyas Gutai, involves a sheet of water being trapped between a panel (嵌板) of glass, and the water is practically invisible. The windows are connected to an indoor storage tank (箱) using pipes hidden in the walls, allowing water to flow easily between the windows and the tank.

This system allows the house to cool and reheat themselves automatically. When sunlight streams through the glass, the windows keep the buildings cool as the water takes in external and internal heat. This warm water then flows back to the tank. And when the outdoor temperature drops, the stored warm water is brought back to the walls to reheat the building using a monitoring system similar to central heating. The heated water can also be used for domestic (家用的) purposes. Although some electricity is required to pump the water back and forth, it uses much less energy than traditional air-conditioners or heaters.

Dr. Gutai claimed that WFG can save energy from 47% to 72% compared to when using traditional windows. Once launched into the market, the windows will surely make a real splash, appealing to a large crowd of environmentalists and contributing to reducing our carbon footprint. Currently, the inventor team is testing the windows in two areas with different weather conditions. The research reveals that WFG systems perform well in any inhabited climate—keeping buildings in hot climates cool and buildings in cool settings warm—without requiring an additional energy supply.

American high school students are terrible writers, and one education reform group thinks it has an answer: robots. Or, more accurately, robot-readers—computers programmed to scan students’ essays and spit out a grade.

Mark Shermis, professor of the College of Education at the University of Akron,is helping to hold a contest, set up by the William and Flora Hewlett Foundation (WFHF), that promises $ 100,000 in prize money to programmers who write the best automated grading software. “If you’re a high school teacher and you give a writing task, you’re walking home with 150 essays,” Shermis said. “You’re going to need some help.”

Automated essay grading was first proposed in the 1960s, but computers back then were not up to the task. In the late 1990s, as technology improved, several textbooks and testing companies jumped into the field. Today, computers are used to grade essays on South Dakota’s student writing assessments and a handful of other exams, including the TOEFL test of English fluency, taken by foreign students.

The Hewlett contest aims to show that computers can grade as well as English teachers—only much more quickly and without all that depressing red ink. “Automated essay scoring is objective,” Shermis said. “And it can be done immediately. If students finish an essay at 10 pm, they will get a result at 10: 01 pm.”

Take, for instance, the Intelligent Essay Assessor, a webbased tool marketed by Pearson Education, Inc. Within seconds, it can analyze an essay for spelling, grammar, organization, and help students to make revisions. The program scans for key words and analyzes semantic (语义的) patterns, and Pearson claims that it can understand the meaning of text much the same as a human reader.
