BBC NEWS | Technology | Physics promises wireless power
US researchers have outlined a relatively simple system that could deliver power to devices such as laptop computers or MP3 players wirelessly.
The concept exploits century-old physics and could work over distances of many metres, the researchers said.
Although the team had not built and tested a system, computer models and mathematics suggest it would work.
“There are so many autonomous devices such as cell phones and laptops that have emerged in the last few years,” said Assistant Professor Marin Soljacic from the Massachusetts Institute of Technology and one of the researchers behind the work.
“We started thinking, ‘it would be really convenient if you didn’t have to recharge these things’.
“And because we’re physicists we asked, ‘what kind of physical phenomenon can we use to do this wireless energy transfer?’.”
The answer the team came up with was “resonance”, a phenomenon that causes an object to vibrate when energy of a certain frequency is applied.

In future the mobile phones were so small and they would be charged from a source that can be tapped easily. The most obvious choices are the solar power and body heat. The charging of batteries will happen automatically, without users having to bother about it.
This experiment is still not proved to be a practically viable solution, but even it becomes viable, it would not have much use because of the reasons above.

The problem with power is that it has health and safety issue,and transferring power over the air should only involve wattages that are within the public safety range. This is normally in mW(mili Watts), But who knows the chips and other miniature components may be created in a way to charge it self up using lower power ranges..!
Nepal’s digital crossroads: building a transparent data governance framework
Nepal’s evolving digital landscape highlights a growing tension between constitutional guarantees of privacy and access to information, and a fragmented, outdated data governance framework. In a recent article published in Republica on March 17, 2026, Avash Mainali, Country Researcher for Nepal for LIRNEasia’s D4D Asia project, argues that while the introduction of the Personal Data Protection Policy, 2082 (2025), marks a positive step, its impact will depend on whether it can move beyond aspirational language to enforceable rights.
LIRNEasia CEO Helani Galpaya Shares Insights on AI and Labour at ISLE Conference 2026
Artificial intelligence is rapidly transforming labour markets worldwide. In the Global South, however, these changes are unfolding unevenly, shaped by labour markets defined by high levels of informality, uneven social protection, and large skills gaps.
LIRNEasia CEO Helani Galpaya at the Global South Policy Dialogue: Securing Labour Justice in the Age of AI
As Artificial Intelligence (AI) continues to transform the world of work, its impacts in the Global South present urgent and unique challenges. Unlike advanced economies with formal labour markets and stronger safety nets, many countries in the Global South face high levels of informality, limited social protection, and unequal access to skills and digital infrastructure.
