Manufacturing Current Affairs - 2020
The researcher from Council of Scientific and Industrial Research (CSIR) has developed light carbon foam that will replace lead batteries. The carbon foam is easy to fabricate, non-toxic and affordable.
The researcher is a recipient of INSPIRE Faculty award. The material developed by the institute has the potential to replace lead-acid batteries. It is also useful to make heat sink, electromagnetic interference shielding in aerospace, electrode for lead-acid batteries, hydrogen storage and water purification systems.
The raw materials to make the carbon foam is easily available. It also helps to remove oil, arsenic and other metals from contaminated water.
Carbon Foam Batteries
The Carbon foams are porous. The pores in the batteries help increase efficiency. The micro cells completely make a new type of electrolyte structure. Hence, the power, energy and life cycle of the batteries increases.
How are carbon foam batteries better than Lead-acid batteries?
Carbon Foam batteries have better life cycle as compared to the lead-acid batteries. They are built three-fifth the cost of other advanced batteries.
India in Carbon Foam Batteries
The world’s first carbon foam manufacturing unit was set up in Gujarat in 2011. 20% of the produce in these industries are being exported and the rest are being used for electric vehicles.

On May 4, 2020, the Government of India implemented phase III of COVID-9 lock down. With the third lock down relaxing restrictions all over the country, major cities are still vulnerable to the spread of the virus. Hence, to fight the virus more efficiently and maintain a routine life, control rooms have been set up in smart cities.
About the control Rooms
The Control rooms have been designed by the private firm Honeywell. The rooms have sophisticated monitoring system. It uses artificial intelligence and camera feeds to monitor the city. The rooms help in generating clear report that will help the authorities to assess the effectiveness of the lock down.
Lock Down 3.0
In Lock Down 3.0, over 130 red regions have been put under red zone. Alongside, 284 orange zones and 319 green zones have been specified. The regions have been sorted based on the cumulative cases and the doubling rate of the virus. Green Zones are those regions that have no confirmed cases in the past 21 days. Red zones are those regions where the number cases doubled. These regions require testing, surveillance feedback.
The cities, especially the metropolitans have become the nerve centres of the virus. On the other hand, they hold the key to economic revival as well. Also, they are the manufacturing hubs. When these cities come to standstill, human lives are greatly affected and so is the economy. Therefore, there is a need to focus both on lives and livelihood.
Hence, the control rooms are important.
