Indian Railways: Push-Pull Locomotive Inspired By Vande Bharat Ready To Haul 22 Non-AC Coaches  higher speed like the Vande Bharat trains, Indian Railways has rolled out push-pull locomotive to haul non-air conditioned coaches In a push–pull train, two locomotives at both ends of a train are used at the same time, being controlled by one driver. The train moves faster in push-pull method and detention time at stations is reduced, improving turnaround time. "Push-pull loco getting ready… noisy, oily, power generator coaches will not be needed once these push-pull locos are installed at both ends of trains," said Railway Minister Ashwini Vaishnaw on a social networking site. Manufactured at Chittaranjan Locomotive Works in West Bengal, at an estimated cost of Rs 28 crore, twin locomotives will move to ICF Chennai to be equipped with 22 non-AC LHB coaches.While four coaches will be kept as reserved, rest 18 will be unreserved coaches. There was a demand for a train with upgraded

ISRO Shares Photos of Gaganmon Mission:                             ISRO said preparations for India's first manned space mission, Gaganyaan, are in full swing. Abort Mission-1, which will be included to enable the safe escape of the astronauts in the middle of this trip, is said to be in progress. ISRO has tweeted the related photos. As part of this project, two astronauts will be taken into a circular orbit 400 km above the Earth for three days.  గగన్మోన్ మిషన్ ఫొటోలను పంచుకున్న ఇస్రో:                                భారత తొలి మానవ సహిత అంతరిక్ష యాత్ర గగన్యాన్కు సన్నాహాలు జోరుగా సాగుతున్నాయని ఇస్రో తెలిపింది. ఈ యాత్ర మధ్యలో వ్యోమగాములు సురక్షితంగా తప్పించుకునేందుకు వీలుగా పొందుపర్చనున్న అబార్ట్ మిషన్-1 పనులు కొనసాగుతున్నాయని వెల్లడించింది. దీనికి సంబంధించిన ఫొటోలను ఇస్రో ట్వీట్ చేసింది. ఈ ప్రాజెక్టులో భాగంగా ఇద్దరు వ్యోమగాములను మూడు రోజులపాటు భూమి నుంచి 400 కి.మీ వృత్తాకార కక్ష్యలోకి తీసుకెళ్తారు.

                There are several types of solar panels, each with its own design and technology. The primary types of solar panels are monocrystalline, polycrystalline, thin-film, and bifacial panels. Here's an overview of these types and how they work efficiently: 1. **Monocrystalline Solar Panels**:     - **Efficiency**:                       Monocrystalline panels are known for their high efficiency and performance. They typically have efficiency rates ranging from 15% to 22%.    - **How They Work**:                              Monocrystalline panels are made from single-crystal silicon. They are highly efficient because their single-crystal structure allows electrons to move more freely, resulting in better energy conversion. 2. **Polycrystalline Solar Panels**:    - **Efficiency**:                            Polycrystalline panels are less efficient than monocrystalline panels, with efficiency rates typically ranging from 13% to 16%.    - **How They Work**:                  

                          Designing solar panels to work efficiently during the rainy season can be challenging, as rain and overcast skies reduce the amount of sunlight available for energy generation. However, there are several strategies and technologies you can consider to improve the performance of solar panels during these conditions: 1. **Advanced Solar Panel Technologies**:    - High-efficiency solar panels: Invest in high-efficiency solar panels, such as monocrystalline or bifacial panel s, which can generate more electricity from limited sunlight. 2. **Energy Storage**:    - Battery storage systems: Install energy storage solutions like lithium-ion batteries to store excess energy generated during sunny days. This stored energy can be used during rainy or cloudy periods to maintain a consistent power supply. 3. **Anti-Reflective Coatings**:    - Apply anti-reflective coatings to the surface of the solar panels. These coatings reduce the reflection of sunlight and enhance lig
