Concentrated Solar Power (CSP) generates electricity by using mirrors or lenses to focus sunlight onto a small area, creating heat that drives a turbine. Unlike photovoltaic (PV) solar panels, CSP systems capture heat, which can be stored, allowing for flexible and dispatchable power generation even after sunset. Common CSP technologies include power towers, parabolic troughs, parabolic dishes, and linear Fresnel reflectors.

 Concentrated Solar Power (CSP) generates electricity by using mirrors or lenses to focus sunlight onto a small area, creating heat that drives a turbine. Unlike photovoltaic (PV) solar panels, CSP systems capture heat, which can be stored, allowing for flexible and dispatchable power generation even after sunset. Common CSP technologies include power towers, parabolic troughs, parabolic dishes, and linear Fresnel reflectors.  
How CSP Works
Concentration: -
Large-area mirrors or lenses concentrate sunlight onto a receiver. 
Heating: -
The concentrated sunlight heats a fluid (like oil, water, or molten salt) within the receiver. 
Steam Production: -
This heated fluid then generates steam to power a conventional steam turbine. 
Electricity Generation:-
 The steam turbine spins an electrical generator to produce electricity. 
Key Benefits -
Thermal Energy Storage (TES): -
CSP plants can store heat in materials like molten salt. This storage allows the plant to continue generating electricity when the sun isn't shining or during peak demand, providing flexibility and reliability.
Industrial Heat Applications: -
Beyond electricity, CSP technologies can deliver high-temperature heat for various industrial processes, such as water desalination and chemical production.
Types of CSP Systems
Power Towers: -
A large field of mirrors (heliostats) tracks the sun and reflects light onto a receiver atop a central tower. 
Parabolic Troughs: -
Long, curved mirrors focus sunlight onto a receiver tube running along the focal line. 
Parabolic Dishes: -
Parabolic-shaped dishes concentrate sunlight onto a receiver, often integrated with an engine at the focal point. 
Linear Fresnel Reflectors:-
 Long, narrow, and slightly curved mirrors focus sunlight onto a receiver tube. 
CSP vs. PV Solar
CSP: -
Uses mirrors to concentrate sunlight into heat to generate electricity via a heat engine. 
Photovoltaic (PV) Solar:
 Uses solar panels (PV cells) to directly convert sunlight into electricity through the photovoltaic effect.

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...
