Rolls-Royce successfully tests hydrogen fuel to run aircraft engine
"An exciting milestone", hydrogen will decarbonise aviation and reshape the
future of flight. One day man will also use zero-emission hydrogen for cars,
ships, heating and everything else, "transforming the way we live our lives."
LONDON, Nov 29: A first in the world, British aircraft engine maker Rolls-Royce
has tested hydrogen fuel for running aircraft engine, instead of the conventional
aviation fuel. A breakthrough, although a long way off, will greatly reduce
carbon emissions and help halt climate change. The test jointly conducted with
Airline EasyJet (AE) was successful.
The ground testing was done at a Government test facility at Boscombe Down,
at a military site on Salisbury Plain open space in southern England. A converted
AE 2100-A turboprop engine was used for the test. The hydrogen for the test
was generated using tidal and wind energy from Scotland's Orkney islands, at
a European facility. A full-scale ground test on a Pearl 15 jet engine will
be conducted soon.
Rolls-Royce and Airline EasyJet (AE) said in a joint statement that they have
"set a new aviation milestone with the world's first run of a modern aero engine
on hydrogen."
Rolls-Royce chief technology officer Grazia Vittadini said that the test was
an “exciting milestone.” "We are pushing the boundaries to discover the zero
carbon possibilities of hydrogen, which could help reshape the future of flight,”
he said.
UK Business and Energy Minister Grant Shapps described the demonstration as
a “prime example of how we can work together to make aviation cleaner while
driving jobs across the country.” He called it a "true British success story."
He said in a statement, "The UK is leading the global shift to guilt-free flying,
and today's test by Rolls-Royce and easyJet is an exciting demonstration of
how business innovation can transform the way we live our lives."
Drawbacks of hydroden fuel
The main problem with hydrogen is it needs to be cooled to minus 253 deg C
to be stored as liquid before converting to gas for use as fuel. Besides, it
may take up more space, the jet will have to be redesigned anyway. It will take
up four times the volume of jet fuel for same performance. Doubts are also being
expressed if it will work for long distance hauls.
The green hydrogen used in the test was produced by splitting water into hydrogen
and oxygen, and the electricity needed for the process came from tidal and wind
energy at the Orkney islands facility. On the other hand, the industrial blue
hydrogen from natural gas emits a lot of carbon dioxide in the production although
it is trapped. In the production of grey hydrogen from fosil gas the CO2 is
realeased into the air.
Airbus is also planning to use a A380 to test hydrogen-powered engines (see
video).
One day man will use zero-emission hydrogen for cars, planes, ships, heating
and everything else.
The United Nations has set a target to achieve net zero carbon emissions by
2050.
The incident has triggered a debate on social media whether the officer refused to take orders from a party leader or he was accused of any corruption, some netizens justifying the handling in either case, that Ratnakar was blocking public welfare work! It is true the Govt machinery has been the enemy Number One of the people of this country, existing for itself and for these politicians, for well over seven decades. India will never make an inch of progress - real progress, not make-believe-progress - unless and until this machinery is eliminated.
ANALYSIS: There have been cases of Britons going to Switzerland to get rid of a miserable life. Now once the House of Lords also passes the Terminally Ill Adults (End of Life) Bill, terminally ill Britons can call it quits with the help of a medical practitioner here itself. But the measure when comes into practice, will have very serious social consequences, it is feared. There won't be comparisons, even as tropes in Latin American folklores. The worst case scenario is of those who are not terminally ill also trying to misuse the provision to leave this world early when life with dignity is not available. But that is, in fact, a political question and not a moral imbroglio!
The CCTV footage and the video circulating on social media do not indicate any serious abnormalities in takeoff or descent, it has been confirmed. The disaster is becoming curiouser and curiouser. The flight path was not curvy. And the aircraft maintained a steady, gliding descent with its nose straight and the wings perfectly level. The pilot's distress call does not specify what prevented lift and climb-out. Here are some expert opinions. The sole purpose is to raise travellers' awareness about air travel.
Many of the victims were charred beyond recognition, making identification difficult. Three hundred nineteen body parts have been sent for DNA matching with relatives to determine the identities.

Trump said, "Elon is not really leaving" and will be "back and forth" to the White House because DOGE is his "baby." "I think he’s going to be doing a lot of things.”
Musk wrote: "My scheduled time as a Special Government Employee comes to an end... The @DOGE mission will only strengthen over time as it becomes a way of life throughout the government." Now on it will be on auto-pilot.
PROGNOSIS: DOGE was prematurely born to protect the country by aborting an impending socio-economic disaster which very few people could see coming.
Although its immediate job was to save American taxpayers billions by slashing waste, eliminating fraud, cutting Government bloat and ensuring utmost efficiency in administration for the good of the people.

Originally from Junagadh, Gujarat, Pataudi was relocated to Etawah Lion Safari in September 2019 before being transferred to Gorakhpur Zoo in 2021. Recently it was receiving treatment for pancreatic and liver infections. After tigress Shakti died in the zoo on May 7 due to bird flu, Pataudi was shifted to Kanpur. Some birds are also reported to have died mysteriously around Gorakhpur. All zoos in UP are closed for fear of a bird flu outbreak.
Three other animals too had died - a tiger, a leopardess and a female wolf. Wolf Bhairavi died last Saturday, leopardess Mona died the Thursday before that and tiger Kesari died on March 30. Some of them had Shakti's symptoms but the cause of death has not been confirmed yet.
As tourist inflow is an indicator of normalcy returning to an erstwhile terrorist infested Valley, the Government has been trying hard to make everything travel-friendly, launching lot many projects and bringing Kashmir on the national rail map that physically completes the process of Kashmir's integration with the rest of India. And that defeats the designs of Pakistan eyeing Kashmir and simply explains a recrudescence of terrorism in J&K.
"It's a big victory not just for Tamil Nadu but for all Indian States. DMK will continue to struggle for and win State autonomy and Federal polity," Chief Minister MK Stalin said.

ANALYSIS: There is a lot of hue and cry around the world over Trump's tariffs. But tariff, simply put, is a tax. But unlike tax, it affects the exporting country too. Domestic prices will go up for some time. Nothing more will happen, good or bad!
What motivated Trump's newfound policy, apart from being a stunt to justify his existence in the White House, is a false realisation that increased tariff will make foreign goods prohibitive, thereby boosting local production, and create more jobs, and more prosperity will ring in! If that is true, India would have been shining by now: Producing own Rolls-Royce La Rose Noire Droptail and Scotch Whiskies! And what about coconut and palm oil by America!

PROGNOSIS: It looks a Real New Trump is emerging - courageous, balanced, powerful and disinterested. Determined to save his country from the cliff, he has done quite a few draconian things that will reduce the burden of debts of the Federal entity, like the golden handshake, stopping senseless funding, pulling out of a worthless WHO. Shutting the Education Department is another. On the other hand, running it is also not the Centre's job either (We will convincingly elaborate it in the next chapter).
In India the scene is just the opposite. Centralisation is the core agenda and identity of the ruling dispensation without which it has no existence, or in other words, it exists for that set of schemes only. A realisation of this never dawned upon any Opposition party in 2014 or any time thereafter, what to talk of being able to see it coming 70 years ago! The consequence of all this violation of basic natural law of the universe we cannot predict.
THE AMERICAN CONUNDRUM: Political venom has migrated to top echelons in the US. It was reported last year NASA has become politicised, vitiated. But NASA refuted the charge. How Boeing developed a glitch but its unmanned return was smooth. When Suni-Wilmore were stranded last June, why the return was set for February? Because that comes only after January 20! SpaceX called the shots, for itself and for Trump. Then the mission was manipulated for March for a better bargain! In between, what made Elon Musk 'predict' during campaign if Kamala Harris wins he would be in jail. In politics, it is said, "the only rule is there are no rules." Difficult times for Americans too.
The terminations are part of a large-scale exercise going on all across Fed departments and organisations to reduce wasteful Government expenditure as decided by a Trump in a mess gone berserk, and improve administrative efficiency following the whims of billionaire and his associate Elon MusK and his DOGE. It has not been shared how terminations are going to raise the efficiency bar! It looks like Trump has stolen some of the prescriptions meant for India. But the American problems are quite different.
Suddenly these colonial clerks feel this effortless, little rule will tremendously enhance security and convenience for the railway passengers manifold. More stations will be covered in the next 77 years! (Also See:
