Witricity or wireless electricity was presented. Witricity uses induction to transmit power through coils without wires. It was proposed in the 1800s by Nikola Tesla but faced issues with power loss and safety. There are short, mid, and long-range techniques for wireless power transfer including inductive coupling, resonant inductive coupling, and microwave transmission. Witricity has applications for charging electric vehicles and devices. While it provides a wire-free solution, issues remain with frequency control for short/mid-range and health and cost for long-range transfer. The presentation concluded wireless transmission will be more common in the future.
Wireless energy transfer or wireless power is the transmission of electrical energy from a power source to
an electrical load without a conductive physical connection. In this paper the technologies available for
Wireless Power Transmission (WPT) and its future possible advancements is being discussed to assume its
feasibility in actual practices.
In our present electricity system much of the power generated is wasted during transmission from power
plants to the consumers passing through cables, substations, etc. With WPT the need for inefficient and
costly, cables, towers, and substations will be eliminated & so will the power losses, finally reducing the
cost of energy. This is one such technology that can make the transmission system highly efficient &
economical. One mere demerit of WPT is that it develops reactive power at a small frequency that is very
biologically compatible and harmful to environment & living beings on over exposure.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

3. In this paper....
1) What do you mean by Witricity ?
2) Need of Witricity.
3) History of wireless power.
4) Techniques to Transfer
5) Application , Pros and cons.
6) Future and conclusion.
4. What is Witricity ?
Obvious definition is :
“Transmission of energy through the air”
Cables are going to replaced by WiTricity
5. Why do we need wireless
electricity???
The need of electricity in every nook and
corner of the world
The demand of eco-friendly power
Requirement of efficient and reliable power
To reduce dependence on wires and batteries
The ever increasing power demand
6. Wireless electricity way
back in the 1800s……..
In the year 1891,Nikola Tesla
proposed the method of wireless
transmission of electric power
One of the greatest breakthroughs
of science at that time
7. zzzzz
Built the wardenclyffe tower
which could broadcast power
wirelessly using far-field
techniques. Called off as it
radiated power into
surroundings raising issues of
→power loss
•Power theft
•Health concerns
The Wardenclyffe
Tower
A dream
crashes……
8. Types of wireless energy transfer
techniques are:-
Short range-Inductive
Coupling
Mid range-
Resonance
Inductive Coupling
Long range –
Microwave
Transmission
9. INDUCTIVE COUPLING
•Uses Electromagnetic Induction concept
•Primary and secondary coils are not connected
with wires.
•Energy transfer is due to Mutual Induction
•This method works only when receiver is in
close proximity to the transmitter
10. Inductive coupling
•Uses Electromagnetic Induction concept
“Oscillating electric field produces magnetic field and
oscillating magnetic field produces electric field”.
11. Resonant Inductive Coupling
Uses almost the same
concept as Inductive
coupling just that the coils
operate at resonant frequency
leading to efficient transfer
of energy over a larger
distance
12. Different Frequency
Resonance
Property of systems to operate at higher amplitudes at particular
frequencies known as resonant frequencies than at others.
When 2 objects operate at same resonant frequency they transfer energy
efficiently between them without interfering with the off resonant objects.
14. www.freepptpresentation.com
Different Frequency
The glass which was having the resonant frequency
as of the singer’s voice accumulated sufficient
energy to explode eventually
The setup powered the bulb even when coils
were not in line of sight .The bulb glowed even
when wood, metal and other devices were
placed in between the coils
15. www.freepptpresentation.com
Microwave
Transmission
→Aims at higher power transfer over longer distances
practically in the range of some miles
→Requires a microwave source, antenna and rectenna.
→Steps:
1.conversion of electrical to microwave energy
2.Capturing of microwave beams by Rectenna
3.conversion of microwave to electrical energy
16. www.freepptpresentation.com
SOLAR POWER SATELLITES:
The most imp. Application or advancement:
→absorb light energy from sun.
→converted to electric energy and beamed to earth stations in form of
microwave beams
→so it can power satellites,aircrafts,even supply electricity to places
where wired connections are not possible at lower prices.
Applications of long range transmission
17. Image of a Rectenna in US with diameter of about half a mile
which is important as 95% of the microwave power is received
by rectennas.US receives about 5000MW of power as a result.

Advantages:
Disadvantages:
1. Efficient and reliable power.
2. Creation of a shock free environment devoid of any chances
of power thefts.
3. Provides solution to the ever increasing demand for power.
4. A solution to reduce e-waste- a more safe environment.
5. A more cost effective methodology for getting electricity to
your houses which includes paying less for use of power.
1.For short and mid range transfer system has to be set at the right
frequency or there would be no power transfer.
2.For long range the installation cost is high while the
microwaves will cause harmful effects to the human.
