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.
Wireless Power Transmission Using Solar Power System elprocus
The main function of wireless power transfer is to allow electrical devices to be continuously
charged and lose the constraint of a power cord. This whole idea was developed by Nicolas
Tesla in 1893, where he developed a system of illuminating vacuum bulbs using wireless
transmission technique.

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.

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.

Wireless power transmission via Space Based Solar Powernikhil gaurav
this presentation tells about how the power is transmitting wireless and how it helps to decrease the losses in power transmission and thus increases efficiency and more important is uses a renewable source of energy(SUN).
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.
Solar tracking system using 8051 microcontrollerVISHAL NAGAR
To increase the unit area illumination of sunlight on solar panels, we designed a solar tracking electricity generation system. The design mechanism holds the solar panel and allows the panel to perform an approximate3-dimensional (3-D) hemispheroidal rotation to track the sun’s movement during the day and improve the overall electricity generation. This system can achieve the maximum illumination and energy concentration and cut the cost of electricity by requiring fewer solar panels, therefore, it has great significance for research and development. The main use of this report is to utilize the maximum power from the sun. Now a day we are in heavy need to use the solar power as in the coming days everything we use might depend on this kind of systems

Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

INTRODUCTION
A great concern has been voiced in recent years
over the extensive use of energy, the limited supply
of resources, and pollution of the environment from
the use of present energy conversion systems.
Thus the search for alternative sources of energy is
being encouraged. The solar power satellite
(SPS) concepts envisions using the constant
availability of light in space to generate
baseload electricity on Earth.
5. 5
The SPS is a gigantic satellite designed as an
electric power plant orbiting in the Geostationary
Earth Orbit (GEO). It consists of mainly three
segments; solar energy collector to convert the
solar energy into DC (direct current) electricity,
DC-to-microwave convert-er, and large antenna
array to beam down the microwave power to the
ground.
6. More intense sunlight.
SPS would be illuminated over 99% of the time.
No need for costly storage devices.
Power can be beamed to the location where it is
needed.
No air or water pollution is created in the
process.

10. 10
PROBLEMS AND POSSIBLE SOLUTIONS
Cost of transporting materials to space can be
minimized by using materials from moon or
asteroids .
Difficulty in construction can be overcome by
using International space station or moon as
construction base.
Routine maintenance can be carried out using
robots.
12. 12
The beamed microwave power transmission system
can be used to transmit power to earth. Its major
advantage is its ability to transfer energy across
large distances.
Basic Parts of beamed microwave power
transmission system are:-
1.DC to microwave conversion
2.A beam forming antenna.
3.Free space transmission
4.Reception and reconversion to DC

Maximum possible DC-DC efficiency --- 76%
Experimental DC-DC efficiency ---54%
14. 14
The solar energy collected is converted into electrical
energy by the solar PV cells. To transmit the power to
earth the SPS converts the DC electricity into
microwaves using an onboard cavity magnetron which
is same as an microwave oven magnetron except
being modified so as to provide directional beam with
less noise.
15. 15
Now the microwave produced needs to be transmitted
so as to be received on earth. The efficiency of
transmission, wavelength used and the distance
depends upon the transmitter and receiver aperture.
The relationship between
aperture to aperture
efficiency and character ר
16. 16
The microwaves are transmitted using phased array antenna
as we have to control the microwave beam direction
accurately and speedily. The phased array is a directive
antenna which generate a beam form whose shape and
direction by the relative phases and amplitudes of the waves
at the individual antenna elements. It has low efficiency but it
steers electrically and thus has no moving parts
17. 17
For accurate target detection and high efficient beam
forming retro-directive system is used. Usually they
have phase conjugate circuits in transmitter or receiver
antenna. A pilot signal transmitted by the target is
received and re-radiated from the phase conjugate
circuit. If the pilot signal is received back by the target
then it is set and power is transmitted.
18. 18
RECTENNA
It is an unique device which spreads over receiv- ing
area and combines the function of antenna and
rectifier. A simple rectenna element consists of a
dipole antenna with an RF diode connected across the
dipole elements. The diode rectifies the AC current
induced in the microwave to produce DC power. The
rectenna will be used as an array for high power MPT
because one rectenna element rectifies a few W only.
The SPS requires a rectenna array whose diameter is
over km. It has an overall efficiency of about 85%. It
has low specific mass of 1-2 kg for each KW of DC
power.
21. 21
ENVIRONMENTAL ISSUES
A suggested microwave beam would have a
maximum intensity at its center of 23 mW/cm^2,
which is comparable to the OSHA safety limit of
10 mW/cm^2.
Over 95% of the beam energy will fall on the
rectenna. The remaining microwave energy will
be absorbed and dispersed well within standards
currently imposed upon microwave emissions
around the world.
Rectennae are supposed to be located at remote
areas.
22. 22
LEGAL ISSUES
SPS needs to be allocated a slot in the
geosynchronous orbit which has limited capacity.
LEO(Low Earth Orbit) can come as a possible
solution.
Another legal concern of using SPS is whether the
satellites that beam energy to Earth are allowed
under international treaties that prohibit military uses
of outer space.
Microwaves may interfere with the communication
signals.
Handling space debris related to SPS may cause
legal concerns.
23. Too little is currently known about the technical,
economic and environmental aspects of SPS to
make a decision about it’s deployment. An SPS
research program could ultimately assure an
adequate information base for these decisions. If
future demand growth is expected to be high,
SPS might be needed early in the 21st
century,
and an increase in research effort would be
justified.

Though this would be extremely safe as the power levels would be about equal to the leakage from a microwave

Experiments in the tens of kilowatts have been
performed at Goldstone in California in 1975 and more recently (1997) at Grand Bassin on Reunion Island.
In 2008 a long range transmission experiment successfully transmitted 20 watts 92 miles (148 km) from a mountain
on Maui to the main island of Hawaii.
