Eun Bin Lee 20150465

Tired of carrying heavy keychains and memorizing a list of passwords for every different sites? Worried your personal information might be hacked? Here’s a solution. The “Everykey.” Everykey is a password encryption device that unlocks every passwords and locks through Bluetooth system. It can be carried in a key chain, or be accessorized as a wrist band. When the person holding their own Everykey is nearby, Everykey unlocks every access-controlled devices the person owns. Devices such as phone, laptop, tablet, house door, car door etc. Then, it locks them back when the person walks away. Everykey also generates secure passwords for website accounts, then automatically logs in and out. Through this innovative invention Everykey, people can live with much comfort and escape from worrying whether their personal information might be hacked.

The Everykey was invented by Chris Wentz. The motive of the invention came from Wentz and his friend’s daily life. Whenever they forgot their computer passwords or lose their apartment keys or dorm keys, they wished for a master key that could access to every online, offline locks. Then, the idea brought into shape when Wentz took an entrepreneurship class during his senior year. In July 2013, after Wenzt’s graduation, the company was formed.

The reason Everykey is significant is because it made people’s life comfortable. Nowadays, almost every people in the world has their own smart phones. Inside one’s smart phone, it is full of applications and remembering every login information for these apps is so stressful. Not only memorizing is stressful but also people literally forgot their own login information. Then, people have to undergo some troublesome processes to restore their login information. However, the Everykey automatically logs a person into the websites when the person is nearby. When the person walk away, it automatically logs the person out. So with Everykey, people won’t have to remember any of their passwords again!

Another reason that Everykey is innovative is that it offers perfect level of security. In this information-oriented society, every people’s personal information is kept in cyber space. This virtual space is always exposed in the danger of being hacked. However, when encrypting, the Everykey automatically creates highly complex, impenetrable passwords for people’s website accounts. This encryption technology that Everykey utilizes, is called AES 128-bit encrypton. The very same technology used in U.S military to protect their top secret documents. Even when a person loses their Everykey, it doesn’t matter. Everykey can be froze remotely, so no one else can use it.

Living in a scientifically modernized society, almost everybody’s personal information is being kept online. To keep their information safe, people come up with more and more complex passwords and then forget them. However, with this groundbreaking device, Everykey, people will be able to keep their personal accounts conveniently and safely. With Everykey, the world will eventually need no more keys, no more passwords.

Sustainable future through solar and wind energy

           With people’s insatiable consumptive habits, we are facing some real problems such as polluted environment or people losing their home because of sea level rises etc. To produce profit without destroying our natural resources and create a sustainable future, people came out with the idea “sustainable development.” For our sustainable future, people should use solar energy system and wind power energy. Through these energy system, people can use energy unlimitedly, keep our Earth unharmed and save money.

             So far, people are depending on natural resources a lot, especially on fossil fuels. The problem is that natural resources including fossil fuels, are limited. They are in danger of running out. However, solar energy and wind energy is limitless. The sun is an unlimited energy source that produces massive heat and light energy. Wind is also an unlimited energy. Since the sun and air will always be here, people can use this powerful energy without worrying.

             With these energies, people can also save our planet and make our future sustainable. The solar energy and wind energy are non-polluting energy source that doesn't emit green-house gases and carbon. By using solar panels, people can use energy without limits while saving our land. In addition, with wind power generation, it is estimated that 1.5million tons of carbon dioxide production will be reduced by 2020. These eco-friendly energies are effective in protecting our planet and so these improved systems will affect our future generation in substance

The most powerful and positive factor of these eco-friendly energies is their economic benefit. As a real example, my friend’s grandparents are actually using solar energy through solar panels. Before using the solar panels, their heating bills were very expensive and costed about 300,000 won. However, after they installed the panels, the cost reduced until 3000 won. As installing the panels are expensive, it is difficult for regular homes to install those panels on their own. To promote people and make sustainable future, government’s economic aid will be necessary.

Because of our selfishness and shortsighted greed, our planet has been devastated. For our future generation, promoting a pleasant environment is essential. To make a sustainable future, sustainable development through solar energy and wind energy is necessary. People will be able to make a better environment with these limitless, eco-friendly, and economic energies.
