Xian smog tower: China builds world’s biggest air purifier

China has constructed Xian smog tower, an experimental air purifying tower touted to be the world’s biggest at height of over 100 meters (328 feet) in an attempt to fight air pollution.

The tower is built in Xian in Shaanxi province and has brought positive effect on chronic smog problem in China. It is undergoing testing by researchers at Institute of Earth Environment at Chinese Academy of Sciences.

Xian smog tower

Xian smog tower project was announced in 2015 to find low-cost method to artificially remove pollutants from atmosphere such as PM2.5, nitrates and sulphur dioxide which are the most harmful to human health.

The polluted air is sucked into glasshouses of tower and is then heated up by solar energy. The hot air then moves through multiple cleaning filters and helps in reducing air pollution. The system in air purifier also works during winters as coatings on greenhouses enable glass to absorb solar radiation at higher efficiency.

According to its original design, the full-sized tower will reach 500 metres (1,640 feet) high with diameter of 200 metres (656 feet). This tower size will capture greenhouses in nearly 30 square kilometres and will be capable of purifying the air for small-sized city.

Signficance

During the tests, the tower has managed to produce more than 10 million cubic metres (353 million cubic feet) of clean air day since its launch. It was able to bring down the smog to moderate levels the day when air quality was severe. However, the results were preliminary as of now. It has also improved quality of air after observations were made over distance of 10 square kilometers in the past few months.

Maharashtra becomes first state to unveil Public Cloud Policy

Maharashtra became first state in country to unveil Public Cloud Policy that virtually mandates state government departments to shift their data storage onto cloud.

Earlier in October 2017, State Government had formed four-member committee to draft policy framework on cloud usage, which had submitted a policy document that’s being now adopted as public cloud policy.

Key Facts

The policy will result in additional private sector investments worth US $2 billion for cloud industry as government is one of biggest creators and consumers of data. It will aim to generate 5 lakh jobs in next five years.

The policy is likely to be formally set in motion through detailed government resolution. In coming days, five to six top cloud service providers like Amazon or Microsoft will be empanelled for data storage onto cloud.

Under the policy framework, state government will make mandatory its various departments for storing data within country and to use public cloud in cases wherever Right to Information Act (RTI) is applicable. Later, it will also allow for enhanced security features for private and sensitive data to be stored on the cloud.

State Innovation and Start-up Policy

The State Cabinet headed by Chief Minister also had approved State Innovation and Start-up Policy. Its objective is to attract Rs.5,000 crore investments in development of incubation and start-ups. It will be applicable till 2022.

Under it, on an average three incubators in each of the 12 designated sectors and develop at least 2,000 start-ups will be established in next five years. It will result in development of at least 10 lakh sq ft of incubation space within the state. It will provide Rs.2,500 crore for youth entrepreneurship activities (1% of State Budget).

Under it, an establishment up to 5 years from date of its registration will be considered as start-up. Its annual turnover must be up to Rs. 25 crore. It should be based on innovative concept, innovative commercialisation of products and services or it can also be based on innovative production methods and processes.
