In this paper, I present the concept of Solar Power Satellites -The solar cells in the satellite will convert sunlight to electricity, which will changed to radio frequency energy, then beamed to a receiver site on earth and reconverted to electricity by using transmitting and receiving antenna with the technology of wireless power transmission (i.e., transmitting power as microwaves in order to reduce the transmission and distribution losses). This concept is also known as Microwave Power Transmission.
This ppt explains how to develop a device for wireless power transfer. It can make a remarkable change in the field of the electrical engineering and eliminates conventional copper cables and current carrying wires.

Wireless power transmission from solar power satelliteSaquib Maqsood
In the near future due to extensive use of energy, limited supply of resources and the pollution in environment from present resources e.g. (wood, coal, fossil fuel) etc, alternative sources of energy and new ways to generate energy which are efficient, cost effective and produce minimum losses are of great concern. Wireless electricity (Power) transmission (WET) has become a focal point as research point of view and nowadays lies at top 10 future hot burning technologies that are under research these days. This paper presents the concept of transmitting power wirelessly to reduce transmission and distribution losses. The wired distribution losses are 70 - 75% efficient. We cannot imagine the world without electric power which is efficient, cost effective and produce minimum losses is of great concern.This paper tells us the benefits of using WET technology specially by using Solar based Power satellites (SBPS) and also focuses that how we make electric system cost effective, optimized and well organized. Solar Power Satellite (SPS) is an energy system which collects solar energy in space and transmits it to the ground. It has been believed as a promising infrastructure to resolve global environmental and energy problems for human beings. Microwave power transmission has been investigated and demonstrated for more than 40 years, but still requires further research regarding high-efficiency power conversion and high-accuracy beam control for SPS application. Moreover, attempts are made to highlight future issues so as to index some emerging solutions.
One of the major issue in power system is the losses occurs during the transmission and distribution of electrical power. As the demand increases day by day, the power generation increases and the power loss is also increased. The major amount of power loss occurs during transmission and distribution. The percentage of loss of power during transmission and distribution is approximated as 26%. The main reason for power loss during transmission and distribution is the resistance of wires used for grid. The efficiency of power transmission can be improved to certain level by using high strength composite overhead conductors and underground cables that use high temperature super conductor. But, the transmission is still inefficient. According to the World Resources Institute (WRI), India’s electricity grid has the highest transmission and distribution losses in the world – a whopping 27%. Numbers published by various Indian government agencies put that number at 30%,40% and greater than 40%. This is attributed to technical losses (grid’s inefficiencies) and theft. Any problem can be solved by state of the art technology. The above discussed problem can be solvedby choose an alternative option for power transmission which could provide much higher efficiency, low transmission cost and avoid power theft. Microwave Power Transmission is one of the promising technologies and may be the righteous alternative for efficient power transmission.
A great concern has been voiced in recent years over the extensive use of energy, the limited supply of resources, and the pollution of the environment from the use of present energy conversion systems. Electrical power accounts for much of the
energy consumed. Much of this power is wasted during transmission from power plant generators to the consumer. The
resistance of the wire used in the electrical grid distribution system causes a loss of 26-30% of the energy generated. This loss implies that our present system of electrical distribution is only 70-74% efficient.
Nikola Tesla is best known for his remarkable statements regarding the wireless transmission of electrical power. His first efforts towards this end started in 1891 and were intended to simply "disturb the electrical equilibrium in the nearby portions of the earth... to bring into operation in any way some instrument." In other words the object of his experiments was simply to produce effects locally and detect them at a distance.
Today every thing is going small so use of wires in electrical equipment also reduced so need of wireless power transmission also get in demand this ppt presentation is all about wireless power transmission and it is real and possible because many people think that it is not possible .

Space-based solar power (SBSP) is the concept of collecting solar power in space (using an "SPS", that is, a "solar-power satellite" or a "satellite power system") for use on Earth.It has been in research since the early 1970s. SBSP would differ from current solar collection methods in that the means used to collect energy would reside on an orbiting satellite instead of on Earth's surface.

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

resulting in CO2 emission threatening the global warming.
Solar energy in space free from the weather conditions is quite
different from that on the earth.
The PV cells in the SPS produce 5 to 10 % times more power at space

5. Working of solar panel
Working Of Wireless Power TransmissionSolar Photovoltaic (PV) panels use silicon crystals, which produce an Electrical current
when struck by light.
In a crystal, the bonds are made of electrons that are shared between all atoms of crystal.
The light gets absorbed by the electrons , and this electrons excited into a higher energy
level .
This electron can then move around the crystal freely, which produces an electrical
current.

6. The liberated electrons will try to
move towards anode
But, because of the crossed electric and
magnetic fields, they move in a circular path
around anode. As they move in a circular path
they pass the cavities of the anode.
The cavities thus resonate and emit microwave
radiations. Hence, in this way the microwaves
are collected from the one end of the
magnetron.

The microwave power source generates microwave power and the output power is controlled
by electronic control circuits.
The waveguide circulator which protects the microwave source from reflected power is
connected with the microwave power source through the coax- waveguide adaptor.
The tuner matches the impedance between the transmitting antenna and the microwave source.
The transmitting antenna radiates the power uniformly through free space to the rectenna.

(SPS)The first concept is proposed to place it in GEO (Geostationary Earth Orbit, 36000 km).
Major drawback of this model was huge launch cost to place such a large size station in
GEO.
Later on SPS (Solar Power Satellite) Model, to place space segment in an equatorial LEO
(Low Earth Orbit) at an altitude of 1100 km to reduce the launch cost.
The solar collector can be either photovoltaic cells or a solar thermal turbine.
