Why is Japan not producing mobiles like China?

Galapagos Mobile

Japan was one of the earliest developers of mobile phones and started the world first internet access services called “i-Mode”. Refer to Wiki for details; i-mode - Wikipedia It became very popular in Japan and became a national standard, while in other part of the world, it was way too advanced and Japan failed to make it a global standard.

Yet i-Mode was so popular, further domestic development continued to win the domestic competition and made the Japanese mobile market far different from any other countries. It was then called as Galapagos Mobile because of its pretty unique evolution just like those uniquely evolved creatures in Galapagos islands.

Soon after an iPhone was released, many Japanese jumped to it as well making the i-Mode obsolete very quickly. But again due to the domestic competition, Japanese phone makers continued releasing new Galapagos mobiles allowing Google to launch Android which in parallel with iPhone became global standards.iPho…

India's first underwater Metro in Kolkata soon

India's first underwater Metro in Kolkata soon


Kolkata, known as the ‘City of Joy’, will experience one of the world’s most marvellous inventions. This is a path-breaking project for India as it is the first time that a tunnel has been constructed beneath a flowing river in the country. The tunnel is being dug 30 metres below the riverbed and is a few metres away from the renowned Howrah Bridge


According to India Today, Managing Director of Kolkata Metro Rail Corporation Ltd, Satish Kumar said,
It will be connecting two main terminals: Howrah and Sealdah—each of which has a footfall of about 10-12 lakh passengers per day. These types of tunnel-boring machines, which we call ‘earth pressure balancing tunnel boring machines’, have been used for the first time in Eastern India.



According to the India Times report, the track will be 16.6 km long and the train will run without a driver. There will be six air-conditioned coaches in the train and it will have a capacity of 1,000 passengers. The total estimated cost of the project is said to be Rs 60 crore and it will be completed by December 2019.
Satish further said to India Today,

For tunnelling below the river, the water tightness, waterproofing, and the design of gaskets were the major challenges, because the tunnel is being constructed for a service of 120 years, so we cannot afford any water leakage during service.
A one-year homework was done before the execution of the plan as tunnelling cannot go on for a long time. After this, all the machines and equipment were shifted to the location for implementation of the project. It has been ensured using the latest technology that the tracks have sharp curves as the train will pass through a lot of heritage buildings.
 
 

India is all set to get its first underwater metro in Kolkata which will pass through a tunnel that is several feet under the Hooghly. The first underwater tunnel transportation is complete while the second one will soon be ready.
