How an Indian - Aaswath Raman, a materials science and engineering professor at the University of California at Los Angeles, & co-founder of SkyCool Systems, is silently scripting a revolution in the field of airconditioning via radiative cooling! popsci.com/science/modern…
CENTURIES AGO, desert-dwelling peoples exploited radiative cooling to make ice. In the evenings, they insulated the walls of large bowls or pits, then poured in water. During the pitch-black night, heat escaped the liquid, and by morning, it was frozen solid.
Tilted toward the sun, the panels absorb almost none of the warmth beating down on them; they even launch some into space. After Grocery Outlet put panels on the roof of the 25K sqft building in late 19, energy use by the store’s refrigeration system dropped by 15%-$6K savings py

Often u must have heard an argument abt Modi Govt spending Rs 24,000 crs on minority scholarships to further the narrative that BJP and RSS are engaged in some sort of minority appeasement, being spread by the gang that hails Owaisi ally as most dharmic leader> Thread follows!
The genesis of this claim by the particular gang is this Dec 19 @SwarajyaMag report filed by @haryannvi swarajyamag.com/ideas/seculari… - what this gang never tells you is that the amt of Rs 24K crores was spent during 6 years on 26 schemes run by Minority affairs ministry
Here is spreadsheet from @SwarajyaMag report to set the matters straight. Rs 24,000 crores over 6 years makes is Rs 4000 cr per year on an average....big deal well...for this gang hell-bent on furthering their narrative it must be so..but reality is lot different- lets examnine

How many of u remember taulayi kutayi of a Hockey umpire by Indian team in Dhaka in 1984 -if I’m not wrong it included Mervyn Fernandes, Joaquim Carvallaho and others
I remember watching 1982 Asiad match where Mullah brothers - Salimullah and Kalimullah along with Hasan Sardar played havoc with Indian defences :)
I think everyone of us who grew up in 80s were all essentially hockey fans as well- followed it with similar intensity as cricket -one match I still remember listening to was Champions trophy match with Germany when Pargat Singh last min brilliance helped Ind make it 5-5 from 2-5

Great to see pahari ornaments from yesteryears make a comeback- proud of my younger sister who copied my late nani’s hansuli’s design taking my mother’s inputs for this.

She did same with out of fashion “gulband” design almost 15 yrs ago and then too she had copied my nani!
Gulband also made a great come back in last few years but pahari jewellers were deft at making some of the most amazing gulband in traditional pahari style!
Another pahari jewellery that is making a comeback is paunchi worn on wrists

Dear @AgnesCallamard kudos to you for diversifying @amnesty into an IT surveillance company as well while doing all these campaigns. But this diversification of yours raises more unanswered Qns and doubts abt ur motivation!
Although the integrity of the supposed database claimed to have been the record of 50,000 telephone nos chosen for snooping by countries allegedly using NSO software - @AgnesCallamard you all have not said a word abt that
The association and collusion of @amnesty and motivated organisation like @citizenlab is established by the fact that they are loaning their employees to you for running Shane projects like #PegasusProject

The implications of this sinister game being played by @rahulgandhi & his media cronies with the help of so called US based agents masquerading as experts -sharing gloomy nos on India’s fight against COVID-is actually faced by those millions of Indians living & working overseas
One of my friend based in Dubai was to go back but he can’t as flights to UAE are banned. Those whose visas are set to expire are facing extra troubles all coz of propaganda unleashed by likes of @rahulgandhi despite India’s stellar record on containing spread & even vaccinations
Thanks to this vicious game played by likes of @RahulGandhi countries have banned flights from India. Even those who are fully vaccinated and are carrying RTPCR certificates are made to fly via Doha or Armenia with 14 days stopover/ reaching Dubai on 15th day- isn’t this sad?

First things first, not just Lambu but Sameer Dar was also killed in this operation that lasted 271 days - test of patience, grit and determination Image
So what helped Army tracked this terrorist was -
1) Weather
2) Lust for phone sex
3) Dachigam
