Scientists have developed a revolutionary method to generate electricity, which, if successfully scaled, could bring your electricity bills down to zero. The reason: production costs would be virtually negligible. Surprisingly, this innovation harnesses the Earth’s rotation itself to produce power. How the Electricity Is GeneratedA team of scientists in the United States has created a small machine capable of producing electricity in a unique way. This device generates power directly from the Earth’s magnetic field as our planet rotates. The experiment was conducted under the leadership of Princeton University in New Jersey, with participation from researchers at NASA’s Jet Propulsion Laboratory. Although the small prototype produced only a few microvolts of electricity, it demonstra...

Many household gadgets and appliances remain plugged in overnight, consuming electricity and potentially affecting your sleep. Unplugging certain devices before going to bed can not only reduce your electricity bills but also improve your sleep quality and prolong the life of your appliances. Here are six items you should always unplug at night. 1. Wi-Fi Router It’s advisable to unplug your Wi-Fi router while sleeping. Continuous operation emits electromagnetic waves, which may subtly disturb your sleep. If you have smart devices that require internet, consider keeping the router out of the bedroom. 2. Phone and Laptop Chargers Leaving phone and laptop chargers plugged in, even when not in use, draws a small amount of power and can pose fire hazards. Unplugging chargers before ...

With the Indian government pushing telecom companies to implement CNAP (Calling Name Presentation), questions are arising about the future of Truecaller in India. Currently, Truecaller has around 250 million users in the country, but CNAP could make its primary feature freely available to users directly through mobile networks. What is CNAP and How Will It Work? CNAP, or Calling Name Presentation, is a network-level feature that displays the caller’s name on incoming calls, replacing the need for any third-party app. Users will no longer need to install additional apps or grant permissions to identify unknown callers. The government aims to implement CNAP to reduce spam calls and enhance user safety. Impact on Truecaller Most Indian users rely on Truecaller to identify incoming...

Artificial Intelligence (AI) is advancing at an unprecedented pace, and 2026 promises even faster development. However, a recent report highlights six potentially alarming predictions for AI, raising concerns about privacy, employment, and international stability. 1. AI Development May Slow Down Global protests against the construction of new data centers are increasing, particularly in the U.S., where social media campaigns are gaining momentum. Countries like China and Russia could exploit this by spreading disinformation, slowing AI development in the West. This could lead to international tensions as misinformation fuels public unrest, hindering AI progress. 2. Bringing Robots into Homes Remains a Challenge AI-powered robots will dominate tech conferences in 2026. Companies...

Is your refrigerator making strange, loud noises that are disturbing your home? Samsung and LG have identified the common reasons behind these sounds and provided simple solutions that can help you fix the problem yourself before it causes any damage. Common Noises and How to Fix Them 1. Loud Grinding or Clanking SoundsIf your fridge produces a grinding or clanking noise, it could be because the condenser fan motor is hitting a thick layer of frost inside the freezer. To resolve this, turn off your fridge for 2–3 hours and keep the doors open. This will allow the frost around the fan motor to melt, enabling the fridge to operate smoothly again. 2. Rattling or Buzzing SoundsRattling or buzzing noises are often caused by improper leveling or poorly arranged items inside the fridge. ...

Scientists have developed an innovative material that can significantly reduce your household electricity consumption. This special sheet prevents heat from escaping, meaning you won’t have to repeatedly turn on your room heater. The Heat-Retaining MOCHI SheetResearchers at the University of Colorado Boulder, USA, have created a completely transparent material called MOCHI, designed for windows. MOCHI can effectively block heat transfer, reducing the need to constantly heat buildings. Globally, nearly 40% of total energy is consumed for heating buildings, but a lot of this heat escapes through windows. MOCHI prevents interior heat from leaking out and stops cold air from entering, making it a game-changer in energy efficiency. A 5-Millimeter MarvelMOCHI is a silicone-based sheet just...
