"Datang Zala Hydropower Station in Tibet".

    China has developed and installed the world's largest 500 MW impulse turbine at the "Datang Zala Hydropower Station in Tibet". The Pelton wheel turbine, built by Harbin Electric Machinery Company, has an outer diameter of 6.23 meters, weighs 80-88 tons, and is made of martensitic steel with 21 water ladles. It is designed for a high-head system with a 671-meter drop, increasing efficiency from 91% to 92.6%. 
  Two such turbines will give the station a total capacity of 1,000 MW, expected to generate 4 billion kWh annually by 2028, equivalent to burning 1.3-1.4 million tons of coal, but reducing CO2 emissions by 3.4-3.7 million tons yearly. 

Key Features and Details:-
Single-unit capacity:-
 500 MW, making it the largest of its kind. 
Type:-
 Pelton wheel impulse turbine. 
Manufacturer:-
 Harbin Electric Machinery Company. 
Location: -
Datang Zala Hydropower Station on the Yuqu River, a tributary of the Nu River in Tibet. 
Turbine Dimensions: -
Outer diameter of 6.23 meters, weight of 80-88 tons. 
Material: -
Martensitic steel with 21 water ladles. 
Head: -
Designed for a high-head system with a 671-meter drop. 
Efficiency: -
Increased from 91% to 92.6% due to the design. 
Total Capacity: -
1,000 MW (two 500 MW turbines). 
Annual Generation: -
4 billion kWh by 2028, equivalent to 1.3-1.4 million tons of coal, according to China Datang Corporation. 
CO2 Reduction: -
3.4-3.7 million tons annually. 
Goal: -
Supports China's 2060 carbon neutrality goal.

Solar Generation in Night hrs

How to get get Solar generations in Night        While standard solar panels cannot generate electricity at night,     New technologies are being developed to address this limitation.      These advancements focus on harnessing the earth's heat or using infrared radiation emitted by the Earth to generate power, potentially creating 24-hour renewable energy sources.  Key Concepts and Technologies :- 1) Anti-Solar Panels (Thermo-radiative Cells):- How they work:-    These panels, also known as thermoradiative cells, work in reverse of traditional solar panels. Instead of absorbing sunlight, they emit infrared radiation into space, which is then converted into electricity.    Nighttime energy:-     They can generate electricity from the difference in temperature between the panel and the surrounding environment, essentially converting the heat escaping into space back into usable power.  Potential:-  ...

Hydrogen at home — It's the end of solar and wind power

  Hydrogen at home — It's the end of solar and wind power         Statement "1000 pounds" per day of hydrogen at home — It's the end of solar and wind power in the world" is not accurate.     While hydrogen can be produced from renewable energy sources like solar and wind power, it's not a replacement for those sources themselves. Hydrogen production via electrolysis, using renewable electricity, is a promising avenue for decarbonization, but it doesn't negate the need for solar and wind power as direct energy sources.  Cause behind its is as under. Hydrogen as an Energy Carrier:-     Hydrogen is an energy carrier, meaning it stores energy produced elsewhere (like from solar or wind) and can be used to power fuel cells or for other applications.  Electrolysis:-     A key method of producing "green" hydrogen involves using electricity from renewable sources (like solar and wind) to split water into hydrogen and oxygen throu...

Lift off the ground during seismic activity, minimizing damage in Japan

Lift off the ground during seismic activity, minimizing damage in Japan     Japan has developed a technology that allows houses to literally lift off the ground during earthquakes, protecting them from damage.    This is achieved using a system of compressed air and sensors that inflate an airbag under the house, lifting it a few centimeters during tremors. The house then gently settles back down when the shaking stops.      Japan has developed innovative earthquake-resistant technology that allows houses to lift off the ground during seismic activity, minimizing damage. This is achieved through systems like the one developed by Air Danshin, which uses compressed air to lift houses on airbags. When sensors detect tremors, the airbag inflates, raising the house a few centimeters and preventing it from shaking violently with the ground.    More detailed explanation: Airbag Technology:- Air Danshin has pioneered the use of large airbags placed b...
