Solar power is a renewable energy source that can help address problems with fossil fuels like climate change. It provides energy access for areas without fossil fuels and can be implemented in many parts of the world. The amount of solar energy available depends on location, time of year, and time of day. By orienting solar panels towards the south at an angle equal to the latitude and accounting for these variables, we can determine how much solar energy is available for power generation or other applications.
Solar energy and it's affect on Earth's atmosphereJeremy Lowe
This PowerPoint explores how the sun's radiant energy affects the different layers of atmosphere. Specifically, it focuses on the effect solar energy has on Earths surface to create wind through the uneven heating of Earth's different surfaces (land vs. water)
Introduction to fuels, properties of fuel oil, coal and gas, storage, handling and preparation of fuels, principles of combustion, proximate and ultimate analysis, calorific values, gasification, composition of coal.
Steam System:
Properties of steam, assessment of steam distribution losses, steam leakages, steam trapping, condensate and flash steam recovery system, identifying opportunities for energy savings.
Insulation and Refractories:
Insulation-types and application, economic thickness of insulation, heat savings and application criteria, Refractorytypes, selection and application of refractories, heat loss.
Waste Heat Recovery:
Classification, advantages and applications, commercially viable waste heat recovery devices, saving potential.

Characterization and the Kinetics of drying at the drying oven and with micro...Open Access Research Paper
The objective of this work is to contribute to valorization de Nephelium lappaceum by the characterization of kinetics of drying of seeds of Nephelium lappaceum. The seeds were dehydrated until a constant mass respectively in a drying oven and a microwawe oven. The temperatures and the powers of drying are respectively: 50, 60 and 70°C and 140, 280 and 420 W. The results show that the curves of drying of seeds of Nephelium lappaceum do not present a phase of constant kinetics. The coefficients of diffusion vary between 2.09.10-8 to 2.98. 10-8m-2/s in the interval of 50°C at 70°C and between 4.83×10-07 at 9.04×10-07 m-8/s for the powers going of 140 W with 420 W the relation between Arrhenius and a value of energy of activation of 16.49 kJ. mol-1 expressed the effect of the temperature on effective diffusivity.

"Understanding the Carbon Cycle: Processes, Human Impacts, and Strategies for...MMariSelvam4
The carbon cycle is a critical component of Earth's environmental system, governing the movement and transformation of carbon through various reservoirs, including the atmosphere, oceans, soil, and living organisms. This complex cycle involves several key processes such as photosynthesis, respiration, decomposition, and carbon sequestration, each contributing to the regulation of carbon levels on the planet.
Human activities, particularly fossil fuel combustion and deforestation, have significantly altered the natural carbon cycle, leading to increased atmospheric carbon dioxide concentrations and driving climate change. Understanding the intricacies of the carbon cycle is essential for assessing the impacts of these changes and developing effective mitigation strategies.
By studying the carbon cycle, scientists can identify carbon sources and sinks, measure carbon fluxes, and predict future trends. This knowledge is crucial for crafting policies aimed at reducing carbon emissions, enhancing carbon storage, and promoting sustainable practices. The carbon cycle's interplay with climate systems, ecosystems, and human activities underscores its importance in maintaining a stable and healthy planet.
In-depth exploration of the carbon cycle reveals the delicate balance required to sustain life and the urgent need to address anthropogenic influences. Through research, education, and policy, we can work towards restoring equilibrium in the carbon cycle and ensuring a sustainable future for generations to come.
2. Why do we need solar power?
Many areas of the world don’t have access to fossil fuels.
3. Problems with fossil fuels
Burning fossil fuels such as coal releases carbon
dioxide and other greenhouse gases.
These gases trap more of the sun’s heat in our
atmosphere, causing climate change.
5. Lack of natural resources
Some countries have used up all of their natural
resources.
Haiti allowed deforestation
to provide wood for heat
The Dominican
Republic did not
