This report discusses the potential contribution that energy derived from the tides and waves can make to overall energy supply in a sustainable way. It covers the topics of wide range like how tides and waves are formed; functions of the possible and popular power generation systems especially tidal barrages,turbines, oscillating water columns and wave farms. Advantages and disadvantages of tidal and wave energy are also briefly discussed. Some cost data’s used give us brief insight into the economic prospects of the tidal and wave energy. By turning to potential along the Indian coastline, we found that India do have a huge potential of tidal and wave energy, though it has started very late. Government
initiatives and extensive research focused on the mentioned relevant opportunities will surely change the energy scenario.
Ocean Thermal Energy Conversion SystemsNaveen Kumar
OTEC or OCEAN THERMAL ENERGY CONVERSION, is a renewable energy technology that converts solar radiation to electric power by use of the world oceans. The use of OTEC as a source of electricity will help reduce the state’s almost complete dependence on imported fossil fuels. About one fourth of the 1.7 * 1013 watts of solar energy reaching the earth’s atmosphere is absorbed by sea water. OTEC can be considered as an indirect solar technology because the surface water are warmed by the sun. OTEC can also be used to produce ammonia, hydrogen, aluminium, chlorine and other chemicals.

• The oceans cover a little more than 70 percent of the Earth's surface.
• This makes them the world's largest solar energy collector and energy storage system.
• On an average day, 60 million square kilometers (23 million square miles) of tropical seas absorb an amount of solar radiation equal in heat content to about 250 billion barrels of oil.
This power point presentation deals ocean energy conversion technique. This tells how ocean energy convert in to useful energy i.e. in accessible form.
OTEC stands for Ocean Thermal Energy Conversion. It use a temperature difference (20 -°C) between the upper layer of ocean surface and bottom layer of ocean surface is required to run the turbine to generate an electricity. Ocean covered 70% of earths surface which is abundant form of solar collector and solar storage capacity. Ocean has an abundant form of renewable source of energy which has a potential to fulfill billions of watts of electricity. Now a days, OTEC is required to generate electricity due to sky rocketing price of oil, natural gas and coal. The objective was how to minimize the cost of Ocean Thermal Energy Conversion Plant.

PHP Frameworks: I want to break free (IPC Berlin 2024)Ralf Eggert
In this presentation, we examine the challenges and limitations of relying too heavily on PHP frameworks in web development. We discuss the history of PHP and its frameworks to understand how this dependence has evolved. The focus will be on providing concrete tips and strategies to reduce reliance on these frameworks, based on real-world examples and practical considerations. The goal is to equip developers with the skills and knowledge to create more flexible and future-proof web applications. We'll explore the importance of maintaining autonomy in a rapidly changing tech landscape and how to make informed decisions in PHP development.
This talk is aimed at encouraging a more independent approach to using PHP frameworks, moving towards a more flexible and future-proof approach to PHP development.

2. Introduction
The ocean cover 70% of the earth surface means ocean is
the world largest solar energy collector & energy stored
system.
So, it possible to generate electricity from the oceanic
thermal energy?
3. (Ocean thermal energy conversion)
Jacques Arsene d’Arsonval (1881)
Energy convert –ocean solar radiation to electric power
Renewable energy(clean & green power)
Hydro energy thermal conversion system
Use temp. differences

fresh water
7. 2) Open Cycle OTEC
Seawater is working fluid
Vacuum
0.3 psia –22 degree c
(boiling point of water)
Boiling water drive to turbine
Give Production of electricity
& fresh water
16. 1) Electricity
Able to provide continuously electricity
Energy losses 20%-30%

completed due to problems with the pipes for pumping the seawater;floating
plant.(IIT))
21. Advantages
Use clean, renewable, natural resource
“0” Carbon emission (sometime little)
Produce electricity as well as fresh water
Reduce dependency on fossil fuel (1.3million barrel p/ye)
Produce 120,000,000 litter fresh water p/day(100MW)
Mariculture -70 tons of shellfish meat grow each
day(100MW)
(Johnson 2013)
22. Disadvantages/Limitations
OTEC produced electricity at present some time cost more
than electricity
OTEC plant not working further 40 degree latitude
The pipe used in OTEC nearly up to 10 mt diameter, there is
animal are sucked into the OTEC system.
Risk of the leakage of Ammonia
Cold water discharge on surface water it dangerous for
marine life ex- Coral reefs
OTEC –Experimental Stage
23. Ocean Thermal Energy Conversion (OTEC) is a technology solution
that directly addresses the key concerns of energy security, global
warming, pollution and depletion of nonrenewable fossil resources.
OTEC provides a clean, reliable energy solution for many areas of the
world.
