[AYUDA] energía casi gratis

Estimadisimo, el objetivo del presente thread, es precisamente discutir los posibles o no, projectos para la obtencion de energia, al margen de a quien le parezca viable o no, discutir las posibilidades.
En cuanto a la obtencion de energia a partir del agua, son muchos los proyectos que han abordado el tema, y no se lo considera tan ridiculo (al margen de que como en todo exista algun truchanman).

En cuanto a si invierto o no, le erraste un poquito, y no estoy fundido todavia

Volviendo al tema, el agua es la fuente de energia (hidraulica) por excelencia desde hace ya bastante tiempo, incluso las usinas nucleares y los submarinos del mismo tipo funcionan con ella (generando vapor) , y han habido intentos varios para aprovechar los elementos que la componen (H2O).- De entre ellos han surgido algunos intentos fructiferos y quizas algunos no tanto, pero sigue siendo un medio energetico "LIMPIO".
Quizas uno de los que mas revuelo causo fue la "Maquina perpetua" de Stanley Meyer`s (misteriosamente envenenado cuando estaba por entrar en produccion suinvento) si bien a posteriori, se demostro que su maquina era un fraude por violar el primer principio de la Termodinamica (de vuelta a lo mismo).

Sin embargo, Meyer demostro que su auto podia llegar desde Loas Angeles a Nueva York, con solo 83 litros de agua

Aun asi, y a pesar de que la separacion del Oxigeno del Hidrogeno por medios electronicos es bastante costosa, estan quienes aseguran que ese costo se ve grandemente amortizado por la excelencia del combustible producido (Hidrogeno y Oxigeno) y hay compañias produciendo "motores" que funcionan con ese principio e incluso se ha desarrollado una herramienta de corte que funciona asi.

Sin ir mas lejos, las aplicaciones basadas en "celulas" de combustible realimentadas, basan su funcionamiento en la produccion de agua y reutilizacion de la misma, ademas de no poseer dispositivos "mobiles" que se desgasten, y esto no es una panacea, sino que es una realidad muy utilizada y desarrollada hoy dia, dado que datan del año 1838 y fueron inventadas por Sir William Groove.

Nuevamente equivocado, el problema quizas sea que vos no crees en nada, por mas que funcione y exista que algunos utilizen el "principio" con otros fines, no niega su funcionalidad.

Hay algo que te quiero corregir y es que los signos no son 12 sino 13, hay un signo olvidado que se llama Serpentario. No digo esto como afirmando que pienso ciertas cosas que si afirma la astrologia como ciertas, sino que la historia siempre se analizo en tiempo y espacio, y hubo un momento en que ese tiempo y espacio fue mal contado, porque las antiguas culturas (por ejemplo mayas, egipcios, griegos) que midieron la rotacion y traslacion del sol decian que eran 13 los signos, es decir 13 partes de un año, por lo tanto las "eras" y los años dentro de ellas varian mucho.
No tiene nada que ver con el foro, pero queria hacer una simple acotacion para que se solucione este malentendido, que por mal que nos pese, es importante para medir ciertas cosas de Astronomia (como la localizacion de las estrellas con respecto al plano estelar que vemos desde la tierra) o cosas de historia xP
saludos!

El agua en la hidraulica no produce ni es fuente de energía, solo es el medio por el cual la misma se transmite. En la máquina térmica, la energía la provee el combustible en forma de calor y no el agua.

Lo que quise decir se entendio bien, y si vas a corregir hacelo de la misma forma.
En una planta hidroelectrica lo que genera la energia es el "movimiento" del agua, mientras que un submarino nuclear se utiliza dicha energia para generar "vapor" de agua y mover sus turbinas, como sea, la misma es la encargada de proveer en un caso la fuerza y en el otro la presion al ser calentada, mientras que en las celulas de combustible se utiliza la separacion del Hidrogeno del Oxigeno.

Saludos!

En el caso de la planta hidroelectrica el que provee el combustible es el sol, evaporando el agua y haciendo que corra cuesta abajo por los rios.

En el caso que pusiste arriba "Black Light Power" hablan de "empujar" los electrones del atomo de H aun mas cerca del nucleo que su ground state, lo cual claramente es una burrada y una estafa, a eso me referia.

Bacterias, ¿una nueva fuente de energía?
Poseen moléculas capaces de “respirar” metales y generar electricidad amigable con el ambiente.

esta es la pagina, apra todo el interesado con el tema cientifico/social/mental.

Atoms and Light Energy

The study of atoms and their characteristics overlap several different sciences. Chemists, Physicists, and Astronomers all must understand the microscopic scale at which much of the Universe functions in order to see the "bigger picture".
Inside the Atom

Just like bricks are the building blocks of a home, atoms are the building blocks of matter. Matter is anything that has mass and takes up space (volume). All matter is made up of atoms. The atom has a nucleus, which contains particles of positive charge (protons) and particles of neutral charge (neutrons). Surrounding the nucleus of an atom are shells of electrons - small negatively charged particles. These shells are actually different energy levels and within the energy levels, the electrons orbit the nucleus of the atom.

The ground state of an electron, the energy level it normally occupies, is the state of lowest energy for that electron.There is also a maximum energy that each electron can have and still be part of its atom. Beyond that energy, the electron is no longer bound to the nucleus of the atom and it is considered to be ionized.When an electron temporarily occupies an energy state greater than its ground state, it is in an excited state. An electron can become excited if it is given extra energy, such as if it absorbs a photon, or packet of light, or collides with a nearby atom or particle.
Light Energy

Each orbital has a specific energy associated with it. For an electron to be boosted to an orbital with a higher energy, it must overcome the difference in energy between the orbital it is in, and the orbital to which is is going. This means that it must absorb a photon that contains precisely that amount of energy, or take exactly that amount of energy from another particle in a collision.

The illustrations on this page are simplified versions of real atoms, of course. Real atoms, even a relatively simple ones like hydrogen, have many different orbitals, and so there are many possible energies with different initial and final states. When an atom is in an excited state, the electron can drop all the way to the ground state in one go, or stop on the way in an intermediate level.
Electrons do not stay in excited states for very long - they soon return to their ground states, emitting a photon with the same energy as the one that was absorbed.
Identifying Individual Types of Atoms


Transitions among the various orbitals are unique for each element because the energy levels are uniquely determined by the protons and neutrons in the nucleus. We know that different elements have different numbers of protons and neutrons in their nuclei. When the electrons of a certain atom return to lower orbitals from excited states, the photons they emit have energies that are characteristic of that kind of atom. This gives each element a unique fingerprint, making it possible to identify the elements present in a container of gas, or even a star.
We can use tools like the periodic table of elements to figure out exactly how many protons, and thus electrons, an atom has. First of all, we know that for an atom to have a neutral charge, it must have the same number of protons and electrons. If an atom loses or gains electrons, it becomes ionized, or charged. The periodic table will give us the atomic number of an element. The atomic number tells us how many protons an atom has. For example, hydrogen has an atomic number of one - which means it has one proton, and thus one electron - and actually has no neutrons.
For the Student

Based on the previous description of the atom, draw a model of the hydrogen atom. The "standard" model of an atom is known as the Bohr model.
Different forms of the same chemical element that differ only by the number of neutrons in their nucleus are called isotopes. Most elements have more than one naturally occurring isotope. Many more isotopes have been produced in nuclear reactors and scientific laboratories. Isotopes usually aren't very stable, and they tend to undergo radioactive decay until something that is more stable is formed. You may be familiar with the element uranium - it has several unstable isotopes, U-235 being one of the most commonly known. The 235 means that this form of uranium has 235 neutrons and protons combined. If we looked up uranium's atomic number, and substracted that from 235, we could calculate the number of neutrons that isotope has.
Here's another example - carbon usually occurs in the form of C-12 (carbon-12) , that is, 6 protons and 6 neutrons, though one isotope is C-13, with 6 protons and 7 neutrons.
For the Student

Use the periodic table and the names of the elements given below to figure out how many protons, neutrons and electrons they have. Draw a model of an atom of the following element: silicon-28, magnesium-24, sulphur-32, oxygen-16, and helium-4.

For the Student

Using the text, define the following terms: energy levels, absorption, emission, excited state, ground state, ionization, atom, element, atomic mass, atomic number, isotope.
A Optional Note on the Quantum Mechanical Nature of Atoms


While the Bohr atom described above is a nice way to learn about the structure of atoms, it is not the most accurate way to model them.
Although each orbital does have a precise energy, the electron is now envisioned as being smeared out in an "electron cloud" surrounding the nucleus. It is common to speak of the mean distance to the cloud as the radius of the electron's orbit. So just remember, we'll keep the words "orbit" and "orbital", though we are now using them to describe not a flat orbital plane, but a region where an electron has a probability of being.
Electrons are kept near the nucleus by the electric attraction between the nucleus and the electrons. Kept there in the same way that the nine planets stay near the Sun instead of roaming the galaxy. Unlike the solar system, where all the planets' orbits are on the same plane, electrons orbits are more three-dimensional. Each energy level on an atom has a different shape. There are mathematical equations which will tell you the probability of the electron's location within that orbit.
Let's consider the hydrogen atom, which we already drew a Bohr model of.

Probable locations of the electron in the ground state
of the Hydrogen atom. What you're looking at in these pictures are graphs of the probability of the electron's location. The nucleus is at the center of each of these graphs, and where the graph is lightest is where the electron is most likely to lie. What you see here is sort of a cross section. That is, you have to imagine the picture rotated around the vertical axis. So the region inhabited by this electron looks like a disk, but it should actually be a sphere. This graph is for an electron in its lowest possible energy state, or "ground state." To the right is an excited state of hydrogen. Notice that at the center, where the nucleus is, the picture is dark, indicating that the electron is unlikely to be there. The two light regions, where the electron is most likely to be found, are really just one region. Remember, you have to mentally rotate this around a vertical axis, so that in three dimensions the light region is really doughnut shaped.

Bien, que lo acabas de leer no supercuerda? porque dice claramente:

"The ground state of an electron, the energy level it normally occupies, is the state of lowest energy for that electron.There is also a maximum energy that each electron can have and still be part of its atom. Beyond that energy, the electron is no longer"

Creo que si hubieras sabido eso de antemano no hubieses publicado lo de "Black Light Power" o al menos te hubieras dado cuenta que era una estafa

De tu pagina:

"This allows the negatively charged electron that is otherwise in a stable orbit to move closer to the naturally attracting, positively charged nucleus to generate power as heat."

Y? Lo que proponen no tiene que ver con la localización espacial del estado fundamental, sino con llevarlo a una energía menor y eso es evidentemente imposible para cualquiera que haya resuelto la ecuación de Schrödinger de un átomo de hidrógeno.

Esto es el análogo no-relativista a llevar a un campo a un estado energético menor que el del vacío. Una huevada total.

Pará con la pseudociencia de una vez por favor.
