For example, rock layers show the sequence of geological events, and the presence and amount of radioactive elements in rocks make it possible to determine their ages.
No need to resort to insults, is there? Anon Fusion power works by merging two hydrogen isotopes, the energy that holds the two SINGLE isotopes together is higher than the amount of energy that holds the single helium atom together at the end, the biproduct of the reaction is the release of energy, significantly more than fission, please go back to GCSE physics.
You will find the weight of the former is Nuclear energy has destroyed our society than the latter. This cracking fission is the source of usable energy. Fusion to helium is a energy consuming byproduct, just trash of this process. Maxx Scott To understand this the issue is binding energy.
The binding energy of one hydrogen atom is greater than the binding energy of the one helium atom. That is where the energy comes from. Its the same as fission, but since we are working with the other end of the periodic table or the chart of the nuclides the split atoms have less binding energy.
Nobody knows what to do with it, including the entire apparatus oozing as its atoms are progressively displaced by collision. Van Snyder Some people are betting on P-B11, but that is even more difficult. Solar energy is the main energy source for life on this planet, and if harnessed wisely, could provide for all the energy our civilization would ever need.
Billions upon billions have been spent on fossil fuel subsidies for already profitable companies to addict our civilization to polluting nonrenewable energy, when the same amount could already have established orbiting solar stations to supply an endless stream of energy for humanity.
At least, that was the hypothesized cost of space solar power back in the s and early s, but with space launch costs now going down, so too would the cost of building such power stations.
But if that seems too ambitious for the near term, progress is still being made in reducing the cost and increasing the efficiency of photovoltaics to capture solar power here on earth.
Fusion energy is already providing a growing share of power for mankind, courtesy of our home star and human ingenuity.
Who could argue with that? Sign me up, Scotty. Send in your plans for those orbiting power stations right now. Make sure you get the patents sorted out. Maybe Greenpeace would even sell their yacht. Then maybe you could get the Russians to put them into orbit for you, like they are doing with out astronauts to the Space Station.
You gonna be rich! Get back to us, ya hear? Mike Richardson Yep, truly a well-reasoned and thoughtful response, which also ignored the literally more down-to-earth solar applications I discussed.
Apparently that blissful ignorance works for some folks, proudly marching us forward into the early 20th century. OWilson Your obtuse naive, smarmy and self evident, politically correct posts need to be questioned from time to time. I have little respect for stalkers and political trolls!
Mike Richardson So you must not respect yourself very much, as you are the very archetype of the poster you bemoan. Seldom do you enter a discussion without veering it off into some political diatribe, railing against the pursuit of knowledge, or insulting other posters and quite frequently, the hosts.
OWilson Sorry, no trolling for you today! Hydrogen bombs have used deuterium and more commonly, tritium, but the sun and other stars manage with simple gravity to compress and heat the simplest form of hydrogen to fuse into helium.
Now if we had some means of duplicating that kind of force — but then again, that would be requiring more energy input than we could hope to gain.
Until then, though, that oldest form of fusion remains in our sky to exploit and benefit mankind. OWilson At least you bring out your mop and bucket, once in a while, to clean up your messes. Quit trying to make yourselves appear more noble than everyone else and start helping to solve some problems beyond just putting forth more hare-brained ideas, that is.
High school is over; time to grow up. OWilson I absolutely agree with you. Considered here, slightly to the right of Atilla the Hun Mike Richardson Looks like you, too, have found a friend, at least once he realizes which one you are.Read chapter 7 Dimension 3: Disciplinary Core Ideas - Earth and Space Sciences: Science, engineering, and technology permeate nearly every facet of modern.
The Sun is the source of energy for most of life on Earth. As a star, the Sun is heated to high temperatures by the conversion of nuclear binding energy due to the fusion of hydrogen in its core.
This energy is ultimately transferred (released) into space mainly in the form of radiant (light) energy. humanity still has a little time to contemplate its warning to the future.
How can we be so sure? If a catastrophe occured tomorrow (giant meteor impact, nuclear armageddon), these sites would be left unmarked and unsealed. The Energy Racket. By Wade Frazier.
Revised in June Introduction and Summary. A Brief Prehistory of Energy and Life on Earth. Early Civilization, Energy and the . Prior to the Tōhoku earthquake and tsunami, Japan had generated 30% of its electrical power from nuclear reactors and planned to increase that share to 40%.
Nuclear power energy was a national strategic priority in Japan. As of May , there are 42 operable reactors in Japan.
Of these, 8 reactors in 5 power plants are operating. Fact or Fiction?: Energy Can Neither Be Created Nor Destroyed. Is energy always conserved, even in the case of the expanding universe?
