The End of Metal Keys?

We don’t really pay attention to small things around us that are naturally just here, existing with us quietly and serving us. One of these are KEYS. Nowadays, they are most commonly manufactured metal objects in the whole world that enable us to open our physical properties – cars, buildings, safes and many others.

As a lot of things, origin of keys also dates back to ancient Babylon and Egypt, when first locks appeared. Egyptians used a wooden toothbrush-shaped key for lifting small pins in wooden locks and unlock the blot. The big disadvantage was that keys and locks were made out of wood and they were quite heavy and bulky.

In ancient Rome, engineers and inventors managed to improve a wooden Egyptian design of locks and keys. By using iron and bronze were able to produce much stronger and smaller locks and keys that could be carried on person.

Old Rusty Keys

Modern “flat keys” were firstly introduced to the public by Linus Yale in mid 1800’s. By using tumbler lock and more sophisticated way of regulating the pins, these flat keys become instant success across entire world. However nowadays electronic locking become more and more popular.

Hotel industry was one of the first that introduced key cards (Atlanta, US, 1979). It was basically a simple card with few holes in it that helped to reduce the electricity waste, hotel staff knew when the guest was still in a hotel room and what is the most important, they didn’t have to change the lock when the key was lost.

Electronic keys are becoming trendy, many brands of cars have key-less ignitions, Hilton hotel chain in US is planning to enable their guests to open their rooms with their smartphones. Electronic keys might control your front door via Bluetooth, open the door automatically when you are nearby, send virtual keys to your relatives and friends or control what time certain people have the access.

Many people may argue that their homes are too precious to entrust technology, key-less systems and smartphones. It could stop working when there is a fire or power cut. What to do then? Although this idea is brilliant and with current innovations might work properly and give us new options, metal keys are still cheaper and safer way of protecting and locking our homes.

Beautiful Luxury Hotels Under the Sea

Is anybody worried about global warming? Due to rises of average temperatures, the polar ices are melting. At its extreme the world could turn into a planet as described in Kevin Costner‘s movie, the Water World where people are forced to live on floating platforms as all the habitable areas are under the risen sea level. Wouldn’t it be good to plan human underwater residences in advance? The hotel industry has taken the first steps.


Probably the world’s smallest underwater hotel and one of the road builders of the underwater architecture industry, The Utter Inn, is located in the Lake Mälaren in Västerås, Sweden. The hotel is a cabin complex that has an outdoor patio and an underwater sleeping berth capsule three meters under the water level. The cabin system is designed for two people and can be rented for $165 a night (source).


A Swedish company has also designed an underwater hotel that operates four meters under water surface in the eastern coast of Africa in an island called Pemba. The Genberg Underwater Hotels‘ design of the Manta Resort allows people to sleep in a deep blue ocean while the the capsules custom designed underwater spotlights attract various sea creatures to mesmerize the residents (source).

dest-poseidon-diningThe island of Fiji is implementing an underwater hotel project. Poseidon Underwater Resorts is going to be opened in a 5,000 acre lagoon 40 feet under sea level. The resort is stated to be “the world’s first permanent one-atmosphere sea floor structure and world’s first true undersea resort”. The Poseidon will have 24 suites with an area of 550 square feet. Customers can also enjoy literature in a library, relax in a spa or even get married in an underwater wedding chapel. One week is estimated to cost about US $30,000 per customer.(source)


Probably the most insane construction project the world has ever witnessed is going to be implemented in Dubai. Dubai’s previous project to build an underwater city of Hydropolis in 2006 did not take off as expected but now a Polish firm Deep Ocean Technology has come up with the concept of the Water Discus Hotel. It will be comprised of a series of scifi-styled discs that have 21 floors below sea level.


The offers its customers a beautiful view to the Persian Gulf from two-person bedrooms. In addition to the unusual accommodation, the proposed hotel is to include a diving center, underwater tourist vehicles, a spa, garden areas, an above-water terrace, and a helipad for guests. (source)



The construction and real estate industry have found their extremes today from the oceans and from space. While the world witnesses these gorgeous buildings to be built, the traditional construction industry keeps steadily on going on ground. As one of its pioneers, Shanghai Metal Corporation strives for premium quality in its construction projects.
