@JioCare Do not buy.. Worst customer service. You will be never be happy after this. They won't register complaint too .. It will take ten days to register complaint after several calls and so on. Do not buy any wifi connection from them. Landline connection which is free is all crap.
@BlueDartCares I asked the guy to come in the evening yesterday to deliver my parcel. He did not turn up. And the tracking shows delivery premise closed. I took off today to receive my parcel and he did not turn up
🚨: Finland successfully transmits electric power through the air without using physical wires.
Scientists successfully transmitted electricity through air using ultrasonic sound waves and laser beams.
Finland is positioning itself at the forefront of a wireless energy revolution, with researchers from the University of Helsinki and the University of Oulu pioneering methods to move electricity without physical cables.
One of the most striking developments involves using high-intensity ultrasonic sound waves to create invisible pathways through the air, effectively guiding electrical sparks along a controlled route.
While currently in the experimental phase, this 'acoustic wire' technology could eventually enable contactless electrical connections and smart interfaces that function entirely without plugs or traditional wiring.
Beyond sound-guided energy, Finnish innovation is also leveraging light and radio frequencies to solve complex power challenges. The private sector is developing 'power-by-light' systems that utilize high-powered lasers to transmit electricity to remote receivers, providing critical galvanic isolation for hazardous environments like nuclear plants and high-voltage stations. Simultaneously, advancements in radio-frequency harvesting are turning ambient waves into 'Wi-Fi for power,' potentially eliminating the need for millions of disposable batteries in low-power IoT sensors. Together, these technologies signal a shift toward a more flexible, cable-free infrastructure for global industry.

@ChennaiMetRail ..I arrived to meenambakkam at 7.31 pm today. Seems like there is malfunctioning bogi connector which connects ladies bogi to gents.
Check out ✔️
@Airtel_Presence@vivek59829 They are absolutely useless...they keep asking for dsl id..i don't know what it is .even after giving registered number.. useless Airtel..
I am waiting for 3 months to complete to move to new provider
@airtelindia@TRAI horrible customer service, wrong commitment, blatant lies from level 1 employees and Lakshmi from the supervisor team. Have been on call for more than 2 hours today, no resolution complaint No. 1052018818 not resolved for more than 24 hours
