What is the Solar Power Satellite (SPSP) concept about?

Last Updated:

AA satellite that uses solar energy to power its own systems only
BA satellite that collects solar energy in space and transmits it to Earth as microwaves
CA satellite that reflects sunlight to illuminate dark regions on Earth
DA satellite used to predict solar storms
Correct Answer: A satellite that collects solar energy in space and transmits it to Earth as microwavesYour Answer: B

Explanation

Solar Power Satellite is a futuristic concept of collecting solar energy in space. Modern satellites already use solar panels to power their own systems. This is a standard feature not the defining concept of SPSP. The SPSP concept is specifically about transmitting energy TO Earth not just powering the satellite itself. The image states: अंतरिक्ष आधारित सौर ऊर्जा (SPSP) के संबंध में सत्य कथन है: अंतरिक्ष आधारित सौर ऊर्जा को ऊर्जा के एक वैकल्पिक स्रोत के रूप में सुझाया जाता है राष्ट्रीय लक्ष्य बनाना चाहिए और SPSP की आपूर्ति वर्षों में बिना रुके 99 प्रतिशत प्रतिशत और इसके अलावा ऊर्जा की बहुतायत में उपलब्धता. SPSP (Solar Power Satellite) concept involves placing large solar panels in geostationary orbit to collect solar energy without atmospheric interference and transmitting it to Earth as microwave radiation which is then converted to electricity by rectenna arrays on the ground. Reflecting sunlight to illuminate dark areas is a different concept called space mirror or solar reflector satellite not SPSP. Predicting solar storms is done by heliophysics observatories like SOHO or ACE satellites not SPSP.

What is heat in physics?

Heat is a form of energy that transfers between objects or systems due to a temperature difference, moving from a hotter body to a cooler one until thermal equilibrium is reached.
