The document discusses three types of mechanical energy storage: pumped hydroelectric storage (PHS), compressed air energy storage (CAES), and flywheels. PHS involves pumping water to a higher elevation and releasing it through turbines to generate power. CAES compresses air underground for later use in power generation. Flywheels store energy kinetically in a spinning rotor. Each technology has benefits like cost-effectiveness (PHS) or ability to help integrate renewable energy, but also challenges such as energy losses or limited locations. Flywheels in particular can have very high cycle life compared to batteries.
A flywheel, in essence is a mechanical battery - simply a mass rotating about an axis.Flywheels store energy mechanically in the form of kinetic energy.They take an electrical input to accelerate the rotor up to speed by using the built-in motor, and return the electrical energy by using this same motor as a generator.Flywheels are one of the most promising technologies for replacing conventional lead acid batteries as energy storage systems.
Battery electric vehicle, plug-in hybrid electric vehicle, conventional vehicle and now fuel cell vehicles. With the advancement of technology new inventions have been made in auto industry in past few years. Do you know what fuel cell vehicle is? This presentation attributes the features of fuel cell vehicles and how it differs from battery electric, plug-in hybrid electric and conventional vehicles. Also have some light on its feasibility and merits & demerits.

Solar thermal power generation systems use mirrors to collect sunlight and produce steam by solar heat to drive turbines for generating power. This system generates power by rotating turbines like thermal and nuclear power plants, and therefore, is suitable for large-scale power generation.
Hybrid power generation by and solar –windUday Wankar
With the development of industry and
agriculture, a great amount of energy such as coal, oil
and gas has been consumed in the world. Extensive
use of these fossil energies deteriorates a series of
problems like energy crisis, environmental pollution
and so on. Everybody knows that the fossil energy
reserves are finite, some day it will be exhausted.
It is possible that the world will face a
global energy crisis due to a decline in the
availability of cheap oil and recommendations to a
decreasing dependency on fossil fuel. This has led to
increasing interest in alternate power/fuel research
such as fuel cell technology, hydrogen fuel, biodiesel,
Karrick process, solar energy, geothermal energy,
tidal energy and wind. Today, solar energy and wind
energy have significantly alternated fossil fuel with
big ecological problems.
With the development of the science and
technology, power generation using solar energy and
wind power is gradually known by more and more
people. And it is widespread used in many developed
countries. The merits of the solar and wind power
generation are very obvious-infinite and nonpolluting.
The raw materials of the solar and wind
power generation derived from nature, and wind
power generation can work twenty-four hours a day,
solar power generation only works by daylight. In
addition, this kind of power generation has no
exhaust emission and there is no influence to the
nature. But it also has some shortcomings. Because
of the imperfect of the technology, equipment of the
solar and wind power generation is very expensive.
By far, it cannot be widely used.
In addition, solar and wind power
generation system affected by the changing of the
weather very much, so it has obvious defects in
reliability compared with fossil fuel, and it is difficult
to make it fit for practical use the lack of economical
efficiency .Because of these problems it needs to
increase the reliability of energy supply by
developing a system which interacts Solar and wind
energy. This kind of system is usually called windsolar

Presentation by Mike Dadd, University of Oxford, Smart Villages Technology Workshop, Cambridge 14 January 2014
The purpose of the workshop was to bring together leading UK researchers to discuss emerging technologies for the sustainable production and use of energy in rural communities in developing countries, and to take a ‘look ahead’ at scientific developments and technologies that might be influential over the next 10 - 20 years. It was held under the auspices of the ‘smart villages’ initiative, a three - year project to advance sustain able energy provision for development in off - grid villages in Africa, Asia and Latin America.
Since conversion of the fuel to energy takes place via an electrochemical process, not combustion.
It is a clean, quiet and highly efficient process- two to three times more efficient than fuel burning.
Waste heat is that which is generated in a process by way of fuel combustion or chemical reaction, and then dumped into the environment even though it could still be reused for some useful and economic purpose.

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.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

Nick � I like this topic very much. I think you could possibly choose all three, with a brief overview of each, comparison of advantages and disadvantages between them, and I think the most course-relevant part which a comparison with electrochemical storage (battery, capacitor, fuel cell). Go for it.
