IIT-Madras develops portable cold storage device

Indian Institute of Technology (IIT) Madras has developed portable solar-powered cold storage device with 500 kg capacity for storing vegetables and fruits, among other items. The device will help farmers store their produce for sufficient time so that it does not get spoilt before it is sold, thereby preventing wastage of agricultural produce. The first unit of device was deployed at farm in Madurantakam in Kancheepuram district in Tamil Nadu.

Solar-powered cold storage device

It has been developed under project funded by Department of Science and Technology (Ministry of Science and Technology) and IIT-M. It provides storage facility with temperature ranging between four and 10 degree Celsius. Using it, vegetables, leaves, flowers and fruits can be stored for 24 hours in the device. Each device is enough for 5 or 6 acres of land or for group of three to four farmers. The unit uses thermal energy storage. The photovoltaic-powered refrigeration system is used to charge indoor thermal battery in form of latent heat during day time and used to maintain temperature (10 C) for 20-24 hours. Each unit costs between Rs 5.5 to Rs 6 lakh and storage capacity could be scaled down based on requirement.

Shakti: IIT Madras develops India’s first indigenous microprocessor

The researchers from Indian Institute of Technology Madras (IIT Madras) have designed India’s first indigenous microprocessor called ‘Shakti’. It is aimed at developing industrial-grade microprocessors and other components of the microprocessor ecosystem. It will also help to reduce dependency on imported microchips and risk of cyber-attacks.

Microprocessors are brain of all computing and electronic devices and are used to operate larger high-speed systems and supercomputers.

Shakti microprocessor

It was designed, developed and booted by IIT Madras with microchip fabricated in ISRO’s Semi-Conductor Laboratory at Chandigarh. It has been developed under project partly funded by Ministry of Electronics and Information Technology (MeitY), as part of two-decade-old efforts to develop indigenous microprocessors.

Its design originates from open source instruction set architecture (ISA), a set of basic instructions called RISC V, which makes it customisable to any device. ISA is programming or machine language and provides commands to processor instructing it on functions to be executed. RISC-V is open, free ISA which enables new era of processor innovation through open standard collaboration. It delivers new level of free, extensible software and hardware freedom on architecture.


It will reduce dependency on imported microchips especially in communication and defence sectors and thus eliminate risk of cyber-attacks. It can be used in mobile computing, wireless and networking systems. It may also provide power to mobile phones, smart meters and surveillance cameras.


IIT M researchers are now conducting research on ‘Parashakti’, an advanced microprocessor for supercomputers.  It will be super scaler processor that will be ready by December 2018. It will have its applications in desktops and 32 such interconnected microprocessors may be used in supercomputers.
