It provides information concerning future research and development for each respective technology. Due to the limitations of fossil fuels, the authors believe further research should be conducted in solar, wind, nuclear, and emerging energy sources as these have the most potential for improvement and utilization in a world with ever increasing demand for sustainable energy resources. 4 | Executive Summary In our modern world one of the most important concerns for the future is energy; specifically renewable energy, as the reserves of oil and gas are depleting and demand for affordable energy increases. With an increase in demand and a decrease in supply it is imperative that alternative sources of energy be explored. Without addressing the concerns associated with the continued production, distribution and use of fossil fuels – concerns such as global warming, acid rain, and disasters like oil spills – we will see this result in a negative impact on our society and environment. Raising public awareness as to the urgency of these issues is the only way that any changes will be made. The objective of this project is not to explain the repercussions of using fossil fuels, but to explore and analyze sources of alternative energy, and the developments in recent technology; allowing them to be harnessed more efficiently and effectively. The energies discussed in our project range from the most common: (solar, wind, and nuclear) to those less prominent: (hydroelectric, hydrogen, biofuel, geothermal, and others). Along with a detailed analysis of each energy source, we provide social implications and a long term outlook with respect to their future utilization. There are several current sources of alternative energy that we believe do not have much room for improvement or further utilization. These energy sources are namely hydroelectric, biofuels, and hydrogen. Their shortcomings do not lend themselves to large scale energy production for the next 100 years. The most promising sources we see for future use are wind and solar power. They have vast room for improvement and are widely applicable on a global scale. Nuclear energy has vast potential as well, providing the public can be properly educated about the risks and benefits. Not only will nuclear fission become much safer and more efficient within the next few decades, but the real possibility of nuclear fusion as an intrinsically safe and powerful source of energy must be taken into account. The combination of new research and development across all aspects of energy production will produce sufficient energy for global consumption without the environmental drawbacks of traditional fossil fuels. Due to the radically different nature of newer alternative fuels, the future applications of such technologies can only be guessed at. Imagine a world with an infinite source of cheap, reliable, and renewable energy; the possibilities reach into space and across the galaxy. 5 | Introduction In this day and age alternative energy has become a major topic among scientists, politicians, scholars, and others. With global warming looming over our heads and the Earth’s natural resources starting to diminish we, as humans, need to change our ways. We can find solutions to these difficulties by looking for alternatives to meet our energy demands. Currently, our consumption of non-renewable energies is too high, and there are many contributors, as well as side effects, to these issues. The first sign that the amount of non-renewable energies we use needs to decline is the fact that non-renewable energies are just that: non-renewable. Eventually, we will run out of these types of energy, and unless we focus our attention on alternative forms, we will have no means of future survival. A recent study has shown that at the current rate of production there is enough coal on Earth to

    小型飛翔体／海外 ［Format 2］ Technical Catalog Category Airborne contamination sensor Title Depth Evaluation of Entrained Products (DEEP) Proposed by Create Technologies Ltd & Costain Group PLC １．DEEP is a sensor analysis software for analysing contamination. DEEP can distinguish between surface contamination and internal / absorbed contamination. The software measures contamination depth by analysing distortions in the gamma spectrum. The method can be applied to data gathered using any spectrometer. Because DEEP provides a means of discriminating surface contamination from other radiation sources, DEEP can be used to provide an estimate of surface contamination without physical sampling. DEEP is a real-time method which enables the user to generate a large number of rapid contamination assessments- this data is complementary to physical samples, providing a sound basis for extrapolation from point samples. It also helps identify anomalies enabling targeted sampling startegies. DEEP is compatible with small airborne spectrometer/ processor combinations, such as that proposed by the ARM-U project – please refer to the ARM-U proposal for more details of the air vehicle. Figure 1: DEEP system core components are small, light, low power and can be integrated via USB, serial or Ethernet interfaces. 小型飛翔体／海外 Figure 2: DEEP prototype software ２．Past experience (plants in Japan, overseas plant, applications in other industries, etc) Create technologies is a specialist R&D firm with a focus on imaging and sensing in the nuclear industry.

  • COLD NUCLEAR FUSION from Pons & Fleischmann to Rossi's E-Cat
    COLD NUCLEAR FUSION from Pons & Fleischmann to Rossi's E-Cat by Martin Bier Twenty-two years have passed since Pons and Fleischmann held their legendary press conference. Presumably, they had realized cold fusion. But it became a classic case of pride before the fall. A few months later, after the results appeared irreproducible, the American Physical Society and the authoritative journals declared it pseudoscience. Nevertheless, cold fusion never totally disappeared. Money has continued to be poured into it and researchers are still working on it. Recently, there has been commotion over an alleged "breakthrough" by Andrea Rossi with his E-Cat. But there are indications that Rossi's E-Cat is a sham. ! PONS EN FLEISCHMANN Martin Fleischmann (1927) was an accomplished British elektrochemist. He had been president of the International Society of Electrochemistry for two years. In 1986, he was allowed to join the Fellowship of the Royal Society. After 1983, he no longer had any teaching duties at the University of Southampton and started spending a lot of time doing research at the University of Utah. Stanley Pons (1943) was from Valdese, North Carolina. He interrupted his chemistry studies for eight years to help run the family business. But in 1975 he picked it up again and in 1978 he received his Ph.D. from the University of Southampton. In 1989, he was head of the chemistry department at the The front cover of Time on May 8, 1989.! University of Utah in Salt Like City. ! 1 The two scientists would have preferred to just publish their results in a scientific journal.

  • Reactor Types[Edit]
    methods of control of rate of fusion reaction The only known way to control a fusion reaction is with an extremely strong and shaped/focused magnetic field. With today's technology we cannot yet make it strong enough. It breaks up in milliseconds after the reaction, stopping the reaction. types of nuclear materials Nuclear material refers to the metals uranium, plutonium, and thorium, in any form, according to the IAEA. This is differentiated further into "source material", consisting of natural and depleted uranium, and "special fissionable material", consisting of enriched uranium (U- 235), uranium-233, and plutonium-239. fissile and fertile materials Fertile material Fertile material is a material that, although not itself fissionable by thermal neutrons, can be converted into a fissile material by neutron absorption and subsequent nuclei conversions In nuclear engineering, fertile material (nuclide) is material that can be converted to fissile material by neutron. Nuclear reactors elements A nuclear reactor, formerly known as an atomic pile, is a device used to initiate and control a self- sustained nuclear chain reaction. Nuclear reactors are used at nuclear power plants for electricity generation and in nuclear marine propulsion. Heat from nuclear fission is passed to a working fluid (water or gas), which in turn runs through steam turbines. These either drive a ship's propellers or turn electrical generators' shafts. Nuclear generated steam in principle can be used for industrial process heat or for district heating. Some reactors are used to produce isotopes for medical and industrial use, or for production of weapons-grade plutonium. As of early 2019, the IAEA reports there are 454 nuclear power reactors and 226 nuclear research reactors in operation around the world.
