Low Temperature Thermal Desalination (LTTD) Technology

Context: Chennai-based National Institute of Ocean Technology (NIOT) will be setting up green, self-powered desalination plant in Lakshadweep.

About LTTD Technology:

  • The LTTD is a process under which the warm surface sea water is flash evaporated at low pressure and the vapour is condensed with cold deep-sea water.
  • It utilizes vacuum pumps for creating a low pressure and low-temperature environment, resulting into evaporation of water at a temperature gradient of 8 °C.
  • The LTTD technology does not require any chemical pre-and post-treatment of seawater and thus the pollution problems are minimal, and the process is suitable for island territories.
  • Since no effluent treatment is required, it gives less operational maintenance problems compared to other desalination processes.

National Institute of Ocean Technology (NIOT)

  • It was established in November 1993 as an autonomous society under the Ministry of Earth Sciences, Government of India.
  • It aims to develop reliable indigenous technologies to solve various engineering problems associated with harvesting of non-living and living resources in the Indian Exclusive Economic Zone.

GPT 4 and It’s Difference from Chat GPT

Context: Recently, OpenAI has said that GPT-4 is supposedly bigger, faster, and more accurate than ChatGPT.

About GPT 4:

  • GPT-4 is a large multimodal model created by OpenAI.
    • Large multimodal model means it can encompass more than just text and accepts images as inputs.
  • GPT-4 also exhibits human-level performance on various professional and academic benchmarks.
  • For example, it can answer tax-related questions, schedule a meeting among three busy people, or learn a user’s creative writing style.
  • GPT-4 is also capable of handling over 25,000 words of text, opening up a greater number of use cases that now also include long-form content creation, document search and analysis, and extended conversations.

How is GPT-4 different from Chat GPT?

  • Image Processing: GPT-4 can be fed images and asked to output information accordingly whereas GPT-3 and ChatGPT’s GPT-3.5 were limited to textual input and output. GPT-4 can process a lot more information at a time.
  • Improved accuracy: GPT-4 significantly reduces hallucinations relative to previous models and scores 40 per cent higher than GPT-3.5 on factuality evaluations.
  • Hard to trick: It will be a lot harder to trick GPT-4 into producing undesirable outputs such as hate speech and misinformation.
  • Focus on more Language: GPT-4 is more multilingual which means that users will be able to use chatbots based on GPT-4 to produce outputs with greater clarity and higher accuracy in their native languages.


Right to Repair

Context: The central government has scaled up its right-to-repair initiative to cover sectors such as consumer durables, electronic devices, automobiles and farm equipment on a unified portal.

  • Problems: The manufacturers don’t reveal full servicing information or stop repairing old models, prompting consumers to buy replacements, a practice known as planned obsolescence.
  • The planned framework: It aims to ease access to repair services not just by original manufacturers but also by reliable third-party technicians to lower costs and lengthen the shelf life of devices, equipment and home appliances.
  • Idea: The idea behind the right-to-repair initiative is to build a consumer-centric ecosystem to increase repairability and bring transparency through collaboration.
