42. Is Energy Conserved In General Relativity? Is energy Conserved in general Relativity? In special cases, yes. In general it depends on what you mean by energy , and what you mean by conserved . http://math.ucr.edu/home/baez/physics/Relativity/GR/energy_gr.html

[Physics FAQ] Original by Michael Weiss and John Baez. Is Energy Conserved in General Relativity? In special cases, yes. In general it depends on what you mean by "energy", and what you mean by "conserved". In flat spacetime (the backdrop for special relativity) you can phrase energy conservation in two ways: as a differential equation, or as an equation involving integrals (gory details below). The two formulations are mathematically equivalent. But when you try to generalize this to curved spacetimes (the arena for general relativity) this equivalence breaks down. The differential form extends with nary a hiccup; not so the integral form. The differential form says, loosely speaking, that no energy is created in any infinitesimal piece of spacetime. The integral form says the same for a finite-sized piece. (This may remind you of the "divergence" and "flux" forms of Gauss's law in electrostatics, or the equation of continuity in fluid dynamics. Hold on to that thought!) An infinitesimal piece of spacetime "looks flat", while the effects of curvature become evident in a finite piece. (The same holds for curved surfaces in space, of course). GR relates curvature to gravity. Now, even in Newtonian physics, you must include gravitational potential energy to get energy conservation. And GR introduces the new phenomenon of gravitational waves; perhaps these carry energy as well? Perhaps we need to include gravitational energy in some fashion, to arrive at a law of energy conservation for finite pieces of spacetime?

February 11, 1996 General Relativity Tutorial - Long Course Outline John Baez This is a longer version of the course outline. If you click on some of the capitalized concepts, you will see more information on them. A TANGENT VECTOR or simply VECTOR at the point p of spacetime may be visualized as an infinitesimal arrow with tail at the point p. The tangent vectors at p form a vector space called the TANGENT SPACE; in other words, we can add them and multiply them by real numbers. Suppose we work in a local COORDINATE SYSTEM with coordinates (x ,x ,x ,x ). (Since we are working in 4d spacetime there are 4 coordinates; we may think of x as the time coordinate t and the other 3 as x, y, and z, but we don't need to think of them this way, since we're using an utterly arbitrary coordinate system.) Then we can describe a tangent vector v by listing its components (v ,v ,v ,v ) in this coordinate system. For short we write these components as v a , where the superscript a, like all of our superscripts and subscripts, goes from to 3. A COTANGENT VECTOR or simply COVECTOR at the point p is a function f that eats a tangent vector v and spits out a real number f(v) in a linear way. Cotangent vectors can be viewed as ordered stacks of parallel planes in the tangent space at p. They don't "point" like tangent vectors do; instead, they "copoint".

Keep those areas off-limits by installing safety gates, which can serve as barricades between rooms and at the tops and bottoms of staircases. Make sure the gate you choose is expandable, so you can adjust it to fit various-sized entrances. Avoid Window Areas If your travel gear includes cribs or playpens, be careful where you set them up. Never place these items or any type of low-standing furniture under or near a window. Curious toddlers exploring new surroundings can accidentally fall through an open window or window screen. Whenever possible, place cribs and furniture on a wall with no windows. Eliminate Small Hazards Replace or Retrofit Older Blinds www.windowcoverings.org

There is a page where there is a really nice, clickable, stepby-step description of how a Proton Exchange Membrane (PEM) works. http://www.protonenergy.com/index.php/html/gasproducts/technology/howpemworks/in

How PEM Works Introduction: Water electrolysis Water electrolysis is simply the splitting of molecules of H O into H , a solid polymer membrane functions to both support the electrolysis reaction and to separate the gases. The proton exchange membrane conducts H ions (protons) directly through its highly stable, completely inert, solid polymer structure. This structure, comprised of a Teflon backbone with sulfonic acid groups attached, passes the proton from one sulfonic acid group to the next, under the influence of an electromotive field, evolving hydrogen at the cathode. As hydrogen evolves, pressure is achieved by simply allowing hydrogen to accumulate within a confined volume to the desired pressure level. The PEM material has no known bubble pressure and is able to withstand thousands of psi when properly supported. Also in How PEM Works: Introduction Step 1: Water dissociation ...

60. ENERGY QUESTIONS Solar energy is a resource rather than a reserve in most places and for general purposelarge scale use. It requires large scale energy storage and very long http://www-formal.stanford.edu/jmc/progress/energy.html

Up to: Sustainabilty ENERGY QUESTIONS Q. Isn't the world running out of energy. A. No. Nuclear and solar energy are each adequate for the next billion years. That's right; billion not just million or thousand. Bernard Cohen published the facts about that. This page assumes the law of conservation of energy. If you don't understand that, look at law of conservation of energy. Here's how you can tell if you don't understand. Several times I have received in email the following idea for powering cars with hydrogen from water. Run the car on hydrogen obtained by splitting water by electrolysis using the car's generator to get the electricity. If you can't quickly explain why that idea can't work, you need to follow the above link. Q. What about fuel for cars? A. The world will run out of petroleum from oil wells. Maybe in 20 years, but more likely in 50 to 100 years. Here are the American Petroleum Institute's estimates of oil supply On 2004 March 10, the Wall Street Journal, had an article about estimates of oil reserves. The gist of the article is that estimates are very uncertain, especially of reserves from countries that don't require accounts from oil extractors and publish the results. The US Geological Survey (USGS) is rather optimistic. Some other analysts think the USGS is too optimistic. If we take the paranoid or merely cynical view, we might suppose that a company would be inclined to exaggerate its own reserves to keep its stock price up and underestimate world reserves in order to keep the oil price up. Maybe governments with oil reserves would have similar motivations. I have no information about whether companies and governments actually do that.
