Of all the viable energy sources space solar emerges as an attractive clean energy source. The laser beam and microwave power transmission systems are currently the most promising technologies for wirelessly transmitting power over the long distance from a satellite in orbit to the surface of the Earth.
Correct answer to the question 12.
Solar energy coming through space is transferred by. This makes solar power a renewable energy source. Natural Solar Energy Greenhouse Effect The infrared visible and UV waves that reach the Earth take part in a process of warming the planet and making life possiblethe so-called greenhouse effect About 30 of the solar energy that reaches Earth is reflected back into space. When we use solar power we dont use any of the Earths resources like coal or oil.
There are many advantages to this. With a solar-to-radio-frequency module there is no storage you convert the solar energy to direct current and then to radio frequency with integrated circuits for transfer to a rectifying. Approximately 30 is reflected back to space while the rest is absorbed by clouds oceans and land masses.
Ultimately we need a way to store energy on a large scale before we can make the switch to renewable sources. Solar energy is harvested from the sun usually through PVs which are arrays of cells containing an appropriate material such as silicon that converts solar radiation into electricity through the PV phenomenon. By radiation conduction and convection.
A possible way around this would be to generate solar energy in space. Solar power is also clean power that doesnt generate a lot of pollution. A wide range of applications use this technology nowadays ranging from residential rooftop power generation to medium-scale utility-level power generation.
Space-based solar power SBSP is the concept of collecting solar power in outer space and distributing it to EarthPotential advantages of collecting solar energy in space include a higher collection rate and a longer collection period due to the lack of a diffusing atmosphere and the possibility of placing a solar collector in an orbiting location where there is no night. The heat of the Sun is transferred to us by radiation because there is a space vacuum between the sun and the Earth and the transfer of heat by radiation doesnt need any material medium through which heat transfers. However there are many technical financial and policy challenges as well as safety and regulatory concerns which must be addressed before successfully generating electrical energy and transmitting it from space to the Earth.
Solar ponds are sometimes used to produce electricity through the use of the organic Rankine cycle engine a relatively efficient and economical means of solar energy conversion which is especially useful in remote locations. Solar Power for Heat Solar power can be used for heating up homes and other buildings. Potential advantages of collecting solar energy in space include a higher collection rate and a longer collection period due to the lack of a diffusing atmosphere and the possibility of placing a solar collector in an orbiting location where there is no night.
The two methods differ in size mode of operation efficiency and cost. When the Suns energy moves through space it reaches Earths atmosphere and finally the surface. A space-based solar power station could orbit to face the Sun 24 hours a day.
At NRL Jaffe has been conducting space-based solar energy research for more than a decade focusing in part on transmitting solar energy from space to Earth. Space-based solar power SBSP is the concept of collecting solar power in outer space and distributing it to Earth. The rest is absorbed into Earths atmosphere.
The Earth receives 174 petawatts PW of incoming solar radiation insolation at the upper atmosphere. Space Solar Power Transmission. Sometimes solar power for heating can be passive.
The atmosphere radiates the equivalent of 59 of incoming sunlight back to space as thermal infrared energy or heat. The theoretical area of the small black dots is sufficient to supply the worlds total energy needs of 18 TW with solar power. A possible way around this would be to generate solar energy in space.
There are many advantages to this. The remaining fractiona net 5-6 percent of incoming solar energyis transferred to the atmosphere when greenhouse gas molecules absorb thermal infrared energy radiated by the surface. This heat energy is transferred throughout the planets systems in three ways.
The Earths atmosphere also absorbs and reflects some of the Suns light so solar cells above the atmosphere will receive more sunlight and produce more energy. The amount of energy carried by solar radiation is normally expressed in terms of the solar constant which measures the quantity of solar energy passing through one square metre of space perpendicular to the direction of travel of the radiation at the average distance of the earth from the sun. Solar ponds are fairly expensive to install and maintain and are generally limited to warm rural areas.
This radiant solar energy warms the atmosphere and becomes heat energy. A space-based solar power station could orbit to face the Sun 24 hours a day.
