India’s first indigenous Floating LiDAR Buoy System was successfully tested off the Muttom coast in Tamil Nadu by the National Institute of Ocean Technology (NIOT). This milestone demonstrates India’s growing capability in advanced marine and atmospheric monitoring technologies. The system uses laser-based remote sensing to measure wind characteristics up to 300 meters above sea level, making it highly useful for offshore wind energy projects. Its design allows deployment in deep-sea conditions and resilience against harsh tropical weather. This innovation also supports India’s renewable energy goals and reduces dependence on costly foreign technology, strengthening self-reliance.

Researchers at IIT Guwahati have developed an innovative dual-purpose material that addresses both clean energy production and water desalination. The material is based on MXene, known for its high electrical conductivity, and is engineered into ultra-thin ribbon-like structures to enhance efficiency. By integrating ruthenium atoms, the catalyst achieves superior performance in hydrogen production with very low energy requirements. Additionally, its strong photothermal properties enable effective solar-powered desalination. This breakthrough provides a sustainable solution for generating carbon-free hydrogen fuel while also producing safe drinking water, making it highly significant for future environmental and energy needs.

Dimethyl Ether (DME) has been identified by scientists at CSIR-NCL, Pune, as a promising alternative to Liquefied Petroleum Gas (LPG). It is considered a clean and eco-friendly fuel due to its low emission of soot and harmful gases. The development includes an indigenous catalyst for efficient production and successful pilot-scale generation. DME can also be blended with LPG, with up to 8% requiring no changes to existing infrastructure. Its adoption could significantly reduce India’s dependence on LPG imports, save foreign exchange, and support schemes like Ujjwala, while also offering applications in the automotive fuel and chemical industries.

The Indian Space Research Organisation carried out the sea level hot test of the CE20 Cryogenic Engine at its Propulsion Complex located in Mahendragiri, Tamil Nadu. This test was conducted at an enhanced thrust level of 22 tonnes, which is crucial for improving the payload capacity of future LVM3 missions. The successful 165-second test demonstrated the engine’s ability to withstand extreme thermal and mechanical conditions. Advanced systems such as a nozzle protection system and multi-element igniter were used, showcasing India’s growing technological capabilities in cryogenic propulsion systems and space exploration.

Perplexity launched the ‘Personal Computer’ AI agent, an advanced digital assistant designed to automate everyday productivity tasks. The system operates on a Mac mini and functions as a digital proxy that can research topics, draft emails, prepare daily briefings, and manage files across different applications and devices. It combines local system operations with cloud-based reasoning to handle complex user requests efficiently. The platform also integrates multiple large language models such as Claude, Gemini, and Grok, allowing them to collaborate during task execution. With built-in security safeguards and continuous operation, the AI agent aims to improve productivity by automating routine digital activities.
