Book excerpt: How solar could spark a clean-energy transition through transformative innovation—creative financing, revolutionary technologies, and flexible energy systems. Solar energy, once a niche application for a limited market, has become the cheapest and fastest-growing power source on earth. What's more, its potential is nearly limitless—every hour the sun beams down more energy than the world uses in a year. But in Taming the Sun, energy expert Varun Sivaram warns that the world is not yet equipped to harness erratic sunshine to meet most of its energy needs. And if solar's current surge peters out, prospects for replacing fossil fuels and averting catastrophic climate change will dim. Innovation can brighten those prospects, Sivaram explains, drawing on firsthand experience and original research spanning science, business, and government. Financial innovation is already enticing deep-pocketed investors to fund solar projects around the world, from the sunniest deserts to the poorest villages. Technological innovation could replace today's solar panels with coatings as cheap as paint and employ artificial photosynthesis to store intermittent sunshine as convenient fuels. And systemic innovation could add flexibility to the world's power grids and other energy systems so they can dependably channel the sun's unreliable energy. Unleashing all this innovation will require visionary public policy: funding researchers developing next-generation solar technologies, refashioning energy systems and economic markets, and putting together a diverse clean energy portfolio. Although solar can't power the planet by itself, it can be the centerpiece of a global clean energy revolution. A Council on Foreign Relations Book

Download or read book Sun Tracker Automatic Solar Tracking Sun Tracking Systems Solar Trackers and Automatic Sun Tracker Systems written by Gerro Prinsloo and published by Gerro Prinsloo. This book was released on 2014-10-12 with total page 436 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book details Solar-Tracking, Automatic Sun-Tracking-Systems and Solar-Trackers. Book and literature review is ideal for sun and moon tracking in solar applications for sun-rich countries such as the USA, Spain, Portugal, Mediterranean, Italy, Greece, Mexico, Portugal, China, India, Brazil, Chili, Argentina, South America, UAE, Saudi Arabia, Middle East, Iran, Iraq, etc. A solar tracker is a device that orients a payload toward the sun. Like a satellite tracker or moon tracker, it tracks the celestial object in the sky on its orbital path of apparent movement. A programmable computer based solar tracking device includes principles of solar tracking, solar tracking systems, as well as microcontroller, microprocessor and/or PC based solar tracking control to orientate solar reflectors, solar lenses, photovoltaic panels or other optical configurations towards the sun. Motorized space frames and kinematic systems ensure motion dynamics and employ drive technology and gearing principles to steer optical configurations such as mangin, parabolic, conic, or cassegrain solar energy collectors to face the sun and follow the sun movement contour continuously. In harnessing power from the sun through a solar tracker or practical solar tracking system, renewable energy control automation systems require automatic solar tracking software and solar position algorithms to accomplish dynamic motion control with control automation architecture, circuit boards and hardware. On-axis sun tracking system such as the altitude-azimuth dual axis or multi-axis solar tracker systems use a sun tracking algorithm or ray tracing sensors or software to ensure the sun's passage through the sky is traced with high precision in automated solar tracker applications, right through summer solstice, solar equinox and winter solstice. From sun tracing software perspective, the sonnet Tracing The Sun has a literal meaning. Within the context of sun track and trace, this book explains that the sun's daily path across the sky is directed by relatively simple principles, and if grasped/understood, then it is relatively easy to trace the sun with sun following software. Sun position computer software for tracing the sun are available as open source code, sources that is listed in this book. Ironically there was even a system called sun chaser, said to have been a solar positioner system known for chasing the sun throughout the day. Using solar equations in an electronic circuit for solar tracking is quite simple, even if you are a novice, but mathematical solar equations are over complicated by academic experts and professors in text-books, journal articles and internet websites. In terms of solar hobbies, scholars, students and Hobbyist's looking at solar tracking electronics or PC programs for solar tracking are usually overcome by the sheer volume of scientific material and internet resources, which leaves many developers in frustration when search for simple experimental solar tracking source-code for their on-axis sun-tracking systems. This booklet will simplify the search for the mystical sun tracking formulas for your sun tracker innovation and help you develop your own autonomous solar tracking controller. By directing the solar collector directly into the sun, a solar harvesting means or device can harness sunlight or thermal heat. This is achieved with the help of sun angle formulas, solar angle formulas or solar tracking procedures for the calculation of sun's position in the sky. Automatic sun tracking system software includes algorithms for solar altitude azimuth angle calculations required in following the sun across the sky. In using the longitude, latitude GPS coordinates of the solar tracker location, these sun tracking software tools supports precision solar tracking by determining the solar altitude-azimuth coordinates for the sun trajectory in altitude-azimuth tracking at the tracker location, using certain sun angle formulas in sun vector calculations. Instead of follow the sun software, a sun tracking sensor such as a sun sensor or webcam or video camera with vision based sun following image processing software can also be used to determine the position of the sun optically. Such optical feedback devices are often used in solar panel tracking systems and dish tracking systems. Dynamic sun tracing is also used in solar surveying, DNI analyser and sun surveying systems that build solar infographics maps with solar radiance, irradiance and DNI models for GIS (geographical information system). In this way geospatial methods on solar/environment interaction makes use use of geospatial technologies (GIS, Remote Sensing, and Cartography).Climatic data and weather station or weather center data, as well as queries from sky servers and solar resource database systems (i.e. on DB2, Sybase, Oracle, SQL, MySQL) may also be associated with solar GIS maps. In such solar resource modelling systems, a pyranometer or solarimeter is normally used in addition to measure direct and indirect, scattered, dispersed, reflective radiation for a particular geographical location. Sunlight analysis is important in flash photography where photographic lighting are important for photographers. GIS systems are used by architects who add sun shadow applets to study architectural shading or sun shadow analysis, solar flux calculations, optical modelling or to perform weather modelling. Such systems often employ a computer operated telescope type mechanism with ray tracing program software as a solar navigator or sun tracer that determines the solar position and intensity. The purpose of this booklet is to assist developers to track and trace suitable source-code and solar tracking algorithms for their application, whether a hobbyist, scientist, technician or engineer. Many open-source sun following and tracking algorithms and source-code for solar tracking programs and modules are freely available to download on the internet today. Certain proprietary solar tracker kits and solar tracking controllers include a software development kit SDK for its application programming interface API attributes (Pebble). Widget libraries, widget toolkits, GUI toolkit and UX libraries with graphical control elements are also available to construct the graphical user interface (GUI) for your solar tracking or solar power monitoring program. The solar library used by solar position calculators, solar simulation software and solar contour calculators include machine program code for the solar hardware controller which are software programmed into Micro-controllers, Programmable Logic Controllers PLC, programmable gate arrays, Arduino processor or PIC processor. PC based solar tracking is also high in demand using C++, Visual Basic VB, as well as MS Windows, Linux and Apple Mac based operating systems for sun path tables on Matlab, Excel. Some books and internet webpages use other terms, such as: sun angle calculator, sun position calculator or solar angle calculator. As said, such software code calculate the solar azimuth angle, solar altitude angle, solar elevation angle or the solar Zenith angle (Zenith solar angle is simply referenced from vertical plane, the mirror of the elevation angle measured from the horizontal or ground plane level). Similar software code is also used in solar calculator apps or the solar power calculator apps for IOS and Android smartphone devices. Most of these smartphone solar mobile apps show the sun path and sun-angles for any location and date over a 24 hour period. Some smartphones include augmented reality features in which you can physically see and look at the solar path through your cell phone camera or mobile phone camera at your phone's specific GPS location. In the computer programming and digital signal processing (DSP) environment, (free/open source) program code are available for VB, .Net, Delphi, Python, C, C+, C++, Swift, ADM, F, Flash, Basic, QBasic, GBasic, KBasic, SIMPL language, Squirrel, Solaris, Assembly language on operating systems such as MS Windows, Apple Mac, DOS or Linux OS. Software algorithms predicting position of the sun in the sky are commonly available as graphical programming platforms such as Matlab (Mathworks), Simulink models, Java applets, TRNSYS simulations, Scada system apps, Labview module, Beckhoff TwinCAT (Visual Studio), Siemens SPA, mobile and iphone apps, Android or iOS tablet apps, and so forth. At the same time, PLC software code for a range of sun tracking automation technology can follow the profile of sun in sky for Siemens, HP, Panasonic, ABB, Allan Bradley, OMRON, SEW, Festo, Beckhoff, Rockwell, Schneider, Endress Hauser, Fudji electric. Honeywell, Fuchs, Yokonawa, or Muthibishi platforms. Sun path projection software are also available for a range of modular IPC embedded PC motherboards, Industrial PC, PLC (Programmable Logic Controller) and PAC (Programmable Automation Controller) such as the Siemens S7-1200 or Siemens Logo, Beckhoff IPC or CX series, OMRON PLC, Ercam PLC, AC500plc ABB, National Instruments NI PXI or NI cRIO, PIC processor, Intel 8051/8085, IBM (Cell, Power, Brain or Truenorth series), FPGA (Xilinx Altera Nios), Xeon, Atmel megaAVR, or Arduino AtMega microcontroller, with servo motor, stepper motor, direct current DC pulse width modulation PWM (current driver) or alternating current AC SPS or IPC variable frequency drives VFD motor drives (also termed adjustable-frequency drive, variable-speed drive, AC drive, micro drive or inverter drive) for electrical, mechatronic, pneumatic, or hydraulic solar tracking actuators. The above motion control and robot control systems include analogue or digital interfacing ports on the processors to allow for tracker angle orientation feedback control through one or a combination of angle sensor or angle encoder, shaft encoder, precision encoder, optical encoder, magnetic encoder, direction encoder, rotational encoder, chip encoder, tilt sensor, inclination sensor, or pitch sensor. Note that the tracker's elevation or zenith axis angle may measured using an altitude angle-, declination angle-, inclination angle-, pitch angle-, or vertical angle-, zenith angle- sensor or inclinometer. Similarly the tracker's azimuth axis angle be measured with a azimuth angle-, horizontal angle-, or roll angle- sensor. Chip integrated accelerometer magnetometer gyroscope type angle sensors can also be used to calculate displacement. Other options include the use of thermal imaging systems such as a Fluke thermal imager, or robotic or vision based solar tracker systems that employ face tracking, head tracking, hand tracking, eye tracking and car tracking principles in solar tracking. With unattended decentralised rural, island, isolated, or autonomous off-grid power installations, remote control, monitoring, data acquisition, digital datalogging and online measurement and verification equipment becomes crucial. It assists the operator with supervisory control to monitor the efficiency of remote renewable energy resources and systems and provide valuable web-based feedback in terms of CO2 and clean development mechanism (CDM) reporting. A power quality analyser for diagnostics through internet, WiFi and cellular mobile links is most valuable in frontline troubleshooting and predictive maintenance, where quick diagnostic analysis is required to detect and prevent power quality issues. Solar tracker applications cover a wide spectrum of solar energy and concentrated solar devices, including solar power generation, solar desalination, solar water purification, solar steam generation, solar electricity generation, solar industrial process heat, solar thermal heat storage, solar food dryers, solar water pumping, hydrogen production from methane or producing hydrogen and oxygen from water (HHO) through electrolysis. Many patented or non-patented solar apparatus include tracking in solar apparatus for solar electric generator, solar desalinator, solar steam engine, solar ice maker, solar water purifier, solar cooling, solar refrigeration, USB solar charger, solar phone charging, portable solar charging tracker, solar coffee brewing, solar cooking or solar dying means. Your project may be the next breakthrough or patent, but your invention is held back by frustration in search for the sun tracker you require for your solar powered appliance, solar generator, solar tracker robot, solar freezer, solar cooker, solar drier, solar pump, solar freezer, or solar dryer project. Whether your solar electronic circuit diagram include a simplified solar controller design in a solar electricity project, solar power kit, solar hobby kit, solar steam generator, solar hot water system, solar ice maker, solar desalinator, hobbyist solar panels, hobby robot, or if you are developing professional or hobby electronics for a solar utility or micro scale solar powerplant for your own solar farm or solar farming, this publication may help accelerate the development of your solar tracking innovation. Lately, solar polygeneration, solar trigeneration (solar triple generation), and solar quad generation (adding delivery of steam, liquid/gaseous fuel, or capture food-grade CO$_2$) systems have need for automatic solar tracking. These systems are known for significant efficiency increases in energy yield as a result of the integration and re-use of waste or residual heat and are suitable for compact packaged micro solar powerplants that could be manufactured and transported in kit-form and operate on a plug-and play basis. Typical hybrid solar power systems include compact or packaged solar micro combined heat and power (CHP or mCHP) or solar micro combined, cooling, heating and power (CCHP, CHPC, mCCHP, or mCHPC) systems used in distributed power generation. These systems are often combined in concentrated solar CSP and CPV smart microgrid configurations for off-grid rural, island or isolated microgrid, minigrid and distributed power renewable energy systems. Solar tracking algorithms are also used in modelling of trigeneration systems using Matlab and Simulink platform as well as in automation and control of renewable energy systems through intelligent parsing, multi-objective, adaptive learning control and control optimization strategies. Solar tracking algorithms also find application in developing solar models for country or location specific solar studies, for example in terms of measuring or analysis of the fluctuations of the solar radiation (i.e. direct and diffuse radiation) in a particular area. Solar DNI, solar irradiance and atmospheric information and models can thus be integrated into a solar map, solar atlas or geographical information systems (GIS). Such models allows for defining local parameters for specific regions that may be valuable in terms of the evaluation of different solar in photovoltaic of CSP systems on simulation and synthesis platforms such as Matlab and Simulink or in linear or multi-objective optimization algorithm platforms such as COMPOSE, EnergyPLAN or DER-CAM. A dual-axis solar tracker and single-axis solar tracker may use a sun tracker program or sun tracker algorithm to position a solar dish, solar panel array, heliostat array, PV panel, solar antenna or infrared solar nantenna. A self-tracking solar concentrator performs automatic solar tracking by computing the solar vector. Solar position algorithms (TwinCAT, SPA, or PSA Algorithms) use an astronomical algorithm to calculate the position of the sun. It uses astronomical software algorithms and equations for solar tracking in the calculation of sun's position in the sky for each location on the earth at any time of day. Like an optical solar telescope, the solar position algorithm pin-points the solar reflector at the sun and locks onto the sun's position to track the sun across the sky as the sun progresses throughout the day. Optical sensors such as photodiodes, light-dependant-resistors (LDR) or photoresistors are used as optical accuracy feedback devices. Lately we also included a section in the book (with links to microprocessor code) on how the PixArt Wii infrared camera in the Wii remote or Wiimote may be used in infrared solar tracking applications. In order to harvest free energy from the sun, some automatic solar positioning systems use an optical means to direct the solar tracking device. These solar tracking strategies use optical tracking techniques, such as a sun sensor means, to direct sun rays onto a silicon or CMOS substrate to determine the X and Y coordinates of the sun's position. In a solar mems sun-sensor device, incident sunlight enters the sun sensor through a small pin-hole in a mask plate where light is exposed to a silicon substrate. In a web-camera or camera image processing sun tracking and sun following means, object tracking software performs multi object tracking or moving object tracking methods. In an solar object tracking technique, image processing software performs mathematical processing to box the outline of the apparent solar disc or sun blob within the captured image frame, while sun-localization is performed with an edge detection algorithm to determine the solar vector coordinates. An automated positioning system help maximize the yields of solar power plants through solar tracking control to harness sun's energy. In such renewable energy systems, the solar panel positioning system uses a sun tracking techniques and a solar angle calculator in positioning PV panels in photovoltaic systems and concentrated photovoltaic CPV systems. Automatic on-axis solar tracking in a PV solar tracking system can be dual-axis sun tracking or single-axis sun solar tracking. It is known that a motorized positioning system in a photovoltaic panel tracker increase energy yield and ensures increased power output, even in a single axis solar tracking configuration. Other applications such as robotic solar tracker or robotic solar tracking system uses robotica with artificial intelligence in the control optimization of energy yield in solar harvesting through a robotic tracking system. Automatic positioning systems in solar tracking designs are also used in other free energy generators, such as concentrated solar thermal power CSP and dish Stirling systems. The sun tracking device in a solar collector in a solar concentrator or solar collector Such a performs on-axis solar tracking, a dual axis solar tracker assists to harness energy from the sun through an optical solar collector, which can be a parabolic mirror, parabolic reflector, Fresnel lens or mirror array/matrix. A parabolic dish or reflector is dynamically steered using a transmission system or solar tracking slew drive mean. In steering the dish to face the sun, the power dish actuator and actuation means in a parabolic dish system optically focusses the sun's energy on the focal point of a parabolic dish or solar concentrating means. A Stirling engine, solar heat pipe, thermosyphin, solar phase change material PCM receiver, or a fibre optic sunlight receiver means is located at the focal point of the solar concentrator. The dish Stirling engine configuration is referred to as a dish Stirling system or Stirling power generation system. Hybrid solar power systems (used in combination with biogas, biofuel, petrol, ethanol, diesel, natural gas or PNG) use a combination of power sources to harness and store solar energy in a storage medium. Any multitude of energy sources can be combined through the use of controllers and the energy stored in batteries, phase change material, thermal heat storage, and in cogeneration form converted to the required power using thermodynamic cycles (organic Rankin, Brayton cycle, micro turbine, Stirling) with an inverter and charge controller. 这本书详细介绍了全自动太阳能跟踪，太阳跟踪系统的出现，太阳能跟踪器和太阳跟踪系统。智能全自动太阳能跟踪器是定向向着太阳的有效载荷设备。这种可编程计算机的太阳能跟踪装置，包括太阳跟踪，太阳能跟踪系统，以及微控制器，微处理器和/或基于PC机的太阳跟踪控制，以定向太阳能反射器，太阳透镜，光电板或其他光学配置朝向太阳的原理。机动空间框架和运动系统，确保运动动力学和采用的驱动技术和传动原理引导光学配置，如曼金，抛物线，圆锥曲线，或卡塞格林式太阳能集热器面向太阳，不断跟随太阳运动的轮廓。 从阳光透过太阳能跟踪器或实用的太阳能跟踪系统利用电力，可再生能源控制的自动化系统需要自动太阳跟踪软件和太阳位置算法来实现控制与自动化架构，电路板和硬件的动态运动控制。上轴太阳跟踪系统，如高度，方位角双轴或多轴太阳跟踪系统使用太阳跟踪算法或光线追踪传感器或软件，以确保通过天空中太阳的通道被跟踪的高精度的自动太阳跟踪器的应用，通过正确的夏至，春分太阳和冬至。一种高精度太阳位置计算器或太阳位置算法是这样的自动太阳能跟踪系统的设计和施工中的重要一步。 В этой книге подробно Автоматическая Solar-Tracking, ВС-Tracking-Systems, Solar-трекеры и ВС Tracker Systems.

Download or read book Los Hijos del SOL written by Constantino Jiménez and published by RubySerrano. This book was released on with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: Es una obra que plantea la tesis, del porque somos hijos del Sol, ya que el 99.85% de la materia existente en nuestro sistema solar la conforma el Sol y el porcentaje restante que incluye a los planetas, satélites naturales, cometas y asteroides son tan solo una pequeña parte de su emanación. Es decir, que todo lo que absolutamente nos rodea es materia solar y por consecuencia se ve afectada en las diferentes etapas por la cercanía o lejanía de nuestro planeta al sol. Así como en la primavera la naturaleza reverdece debido a esta influencia solar, vemos que en el invierno las mismas personas son más susceptibles a enfermedades e incluso a la muerte, pues de ahí proviene el dicho popular “en enero y febrero desviejadero”. ADQUIERELO AQUI Después de hacer un breve análisis de nuestro sistema solar, de nuestra naturaleza terrestre y considerar las diferentes culturas ancestrales como la Maya, Azteca, Inca y Egipcia donde consideraban al Sol como el centro de sus vidas, surge la investigación del primer monarca en la historia de la humanidad que establece el monoteísmo en la XVIII dinastía faraónica egipcia. Encontrándose involucrados los nombres de Tutmois IV, Amenosis III y Amenosis IV, que posteriormente cambiara su nombre por el de Akhenatón, en una relación muy interesante con los personajes bíblicos que conforman la trinidad mosaica, donde las coincidencias rebasan en gran medida la casualidad, marcándose la posibilidad de que dichos personajes del antiguo testamento en realidad sean tan solo una alegoría de los hechos que se presentaron en Egipto

Book excerpt: ‘PREMIOS’ ‘Medalla de Plata – Concurso de Libros Favoritos de los Lectores Internacionales y Reseñas de 5 Estrellas’ ‘Premio de Oro al Libro Literario Titan y Reseñas de 5 Estrellas’ ‘Bestseller en Amazon – #1 Historia de Oriente Medio y #2 Historia de Civilizaciones Antiguas’ Los dioses Anunnaki del planeta Nibiru llevaron a cabo una misión en la Tierra, y la historia fue documentada en tabletas de arcilla o textos mesopotámicos descubiertos en las ruinas de edificios en Oriente Medio. Los académicos han propuesto que algunas historias del Génesis ya habían aparecido en textos Mesopotámicos hace miles de años. Esta propuesta nos motivó a evaluar los textos más relevantes. Aunque la mayoría de los académicos creen que los textos mesopotámicos son mitología, la investigación se realizó bajo la premisa de que su contenido corresponde a hechos reales. El análisis de las traducciones académicas de los textos reveló que muchos detalles críticos para comprender la historia no han sido revelados. Un análisis exhaustivo de los datos determinó las fechas más probables de los hechos. El libro presenta los acontecimientos relacionados con la llegada de los Anunnaki a la Tierra y las consecuencias de su misión de manera cronológica según los hallazgos en textos Mesopotámicos y libros antiguos. Diversas fuentes, entre ellas libros apócrifos, informes de historiadores antiguos, investigaciones científicas y registros arqueológicos, complementaron la investigación. Se descifraron muchos enigmas, entre ellos quiénes eran los Anunnaki y los Igigi (vigilantes, Nephilim). ¿Por qué, cuándo y cómo se originó el H. sapiens, cómo surgieron las otras especies y por qué se extinguieron? ¿Por qué y cuándo llegaron los Anunnaki y finalmente abandonaron la Tierra? ¿Cuándo regresará el planeta Nibiru a nuestra zona en el sistema solar interior? Los resultados y hallazgos de esta investigación merecen ser conocidos debido a la probabilidad de que las historias de los textos Mesopotámicos realmente sucedieran. Las propuestas del libro difieren de lo que hemos aprendido en las instituciones educativas sobre el origen de la humanidad e invitan al pensamiento crítico para reflexionar sobre la historia de los dioses Anunnaki. Los lectores entusiastas de la temática extraterrestre encontrarán propuestas innovadoras.

Download or read book Pluto and the Universe Plut N y El Universo written by Fabiola Johnson and published by Palibrio. This book was released on 2011-06 with total page 71 pages. Available in PDF, EPUB and Kindle. Book excerpt: ABOUT THE BOOK Pluto and the Universe is a book that contains a play in English and Spanish and that could be read and/or staged by a minimum of ten and a maximum of seventeen, children, teens and adults alike. Intended for young audiences who not only will see and hear the characters who share outer space with Pluto, but will also reflect upon their place in the world and the importance of belonging, or not, to a particular group. With astronomical data and a story about an element who is expelled from the "system", spectators and readers are witnesses to an anecdote that is not so distant or different from one a human being can have here on Earth. The play takes place in 2006 (year on earth) in and around the solar system. The Sun has called for an alignment in order to inform the nine planets of the three recent requirements for classifying as a planet of the solar system. Firstly, they must orbit the Sun, secondly, have a spheroid shape and also clear their orbital environment. The audience will learn how all of the planets meet these requirements, except for Pluto who is not willing to go. He must meet Charon, Halley's Comet, an asteroid, a star and the Oort Cloud in order to comprehend the importance of being unique and a necessary part of this wonderful place called, the Universe. Plutón y el Universo es un libro que contiene una obra de teatro en inglés y en español ideal para un mínimo de diez actores y un máximo de diecisiete. Podrá ser leída y/o puesta en escena por niños, jóvenes y adultos. Dirigida a un público de niños y jóvenes que no sólo verán y escucharán a los personajes que comparten el espacio exterior con Plutón, también reflexionarán sobre su lugar en el mundo y la importancia de pertenecer o no, a un grupo en particular. Con datos astronómicos y una historia de un integrante que es expulsado de su lugar, podrán ser testigos de una anécdota que no es tan lejana o distinta a la de un humano en la Tierra. La obra se desarrolla en el año 2006 (de los terrícolas) en el sistema solar y sus alrededores. El Sol ha citado a los nueve planetas a una alineación ya que debe informarles acerca de los tres nuevos requerimientos para poder ser un planeta del sistema solar. Deberán orbitar al Sol, ser esféricos y despejar las inmediaciones de su órbita. El público se entera de cómo y porque todos cumplen, menos Plutón, que tendrá que dejar de llamarse el noveno planeta del sistema solar. Este no acepta y deberá de conocer a Caronte, al Cometa Halley, a un asteroide, a una estrella y a la gran Nube de Oort para comprender la importancia de ser único y necesario en este grandioso espacio llamado, Universo.
