Researchers take next step toward fusion energy

Fusion is the process that powers the sun, harnessing it on Earth would provide unlimited clean energy. However, researchers say that constructing a fusion power plant has proven to be a daunting task, in no small part because there have been no materials that could survive the grueling conditions found in the core of a fusion reactor. Now, researchers at Texas A&M University have discovered a way to make materials that may be suitable for use in future fusion reactors.

The sun makes energy by fusing hydrogen atoms, each with one proton, into , which contain two protons. Helium is the byproduct of this reaction. Although it does not threaten the environment, it wreaks havoc upon the needed to make a reactor.

"Helium is an element that we don't usually think of as being harmful," said Dr. Michael Demkowicz, associate professor in the Department of Materials Science and Engineering. "It is not toxic and not a greenhouse gas, which is one reason why fusion power is so attractive."

However, if you force helium inside of a solid material, it bubbles out, much like carbon dioxide bubbles in carbonated water.

"Literally, you get these helium bubbles inside of the metal that stay there forever because the metal is solid," Demkowicz said. "As you accumulate more and more helium, the bubbles start to link up and destroy the entire material."

Working with a team of researchers at Los Alamos National Laboratory in New Mexico, Demkowicz investigated how helium behaves in nanocomposite solids, materials made of stacks of thick metal layers. Their findings, recently published in Science Advances, were a surprise. Rather than making bubbles, the helium in these materials formed long channels, resembling veins in living tissues.

"We were blown away by what we saw," Demkowicz said. "As you put more and more helium inside these nanocomposites, rather than destroying the material, the veins actually start to interconnect, resulting in kind of a vascular system."

This discovery paves the way to helium-resistant materials needed to make a reality. Demkowicz and his collaborators believe that may move through the networks of veins that form in their nanocomposites, eventually exiting the material without causing any further damage.

Demkowicz collaborated with Di Chen, Nan Li, Kevin Baldwin and Yongqiang Wang from Los Alamos National Laboratory, as well as former student Dina Yuryev from the Massachusetts Institute of Technology. The project was supported by the Laboratory Directed Research and Development program at Los Alamos National Laboratory.

"Applications to fusion reactors are just the tip of the iceberg," Demkowicz said. "I think the bigger picture here is in vascularized solids, ones that are kind of like tissues with vascular networks. What else could be transported through such networks? Perhaps heat or electricity or even chemicals that could help the material self-heal."

Takes proximity and low delta E for centers to meld. Better if you use pairs, a + and - or proton and electron as a pair; However, the formation of a Nucleus would be easier without the electron shell. Groups with like polarity, that is both neutral, then the unlike charge will attract another group and the like charges will repel the group; however, charges always comply; therefore, they will be pulled together. Either by very low energetic bounding, or slightly high(definable range). Thus results of either a bigger nucleus or orbiting charges. Within a plasma, bets are off. Too high of relative velocities. More likely ions or free particles, you probably can define the population based upon the container energy.

Unlike charges only need be closer together than the like charges; also, the superimposed centers will follow. The modulation of the superimposed centers then is a function of all the motion and instantaneous position. You may calculate this expected delta using gravity; but, please note it may be localized to a set value but it is more likely a time varying motion between the two superimposed values, i.e. gravity.

No matter how well you understand the nature of the universe that allows for us; one must see that something from nothing makes no sense. With the existence of q, and only q, we may exist.

So a lot of atoms are formed in free fall or as a hydrogen cloud collapses. By the way, from the sun, we see the "wrinkles" in the field as energy, h nu. meh. So for the wrinkles all we need is charge motion. Fusion would not work. So the sun is probably at some unknown state of stability at it's center, but the stuff falling into her, or her aura, (degrees of freedom) is creating what we see. You may define the entire "mass" with logic, but not this $hit.

HF,
Notice how the HE nanochannel is at an angle? Does it remind you of the Grand Gallery chamber in the Cheops pyramid?
These guys have solved the function of it's construction! A Fusion Device!

Okay now... Obviously the Ancient Egyptians and their Alien Advisors were so much wiser and more knowledgeable than today's scientists and engineers.

None of the gibberish sputtering claimants for such esoteric nonsense have explained... Exactly what use a magical pyramid of fusion was used for? Cause, no lightbulbs!

And based on their own logic-trap, propounded by the believers of such comicbook claptrap. Would they not also be included with the rest of us modern ignoramuses?

However, let us speculate. A modern fusion reactor is built at hideous costs. But never used for anything but a burial chamber for some bombastically overbearing, hirsutedly orange, under-performing, senile buffoon of Want-to-be-an-Autocrat.

Yeah, I could go for that!

We steal are, smarter that is. There is always a potential difference between any two points on earth. In fact there is a sea of energy there for the taking. However, ya gotta know WTF you're talking 'bout!

Hf, I'm not kidding here. You invent, construct, troubleshoot a working pyramid-magic power plant?

That I and hired experts can physically touch, inspect, disassemble and reassemble? That produces and outputs a measurable wattage. And I mean, more energy than it consumes?

Please contact me and lug it over here! As I have an imaginary fortune to invest in imaginary products.

Really? Energy, i.e. radiation, is produced from charge motion, not charge fusion. The sun has a load of these free charges that simply bounce around for you pleasure. There are even events of active anti-matter streams creating burst of energy. But you are asking for the impossible. Some kind of nonsense energy created by how you think.

rrwillsj Where did you get your education? I prefer to think for myself; so, I dismiss any school that has all the smarta$$es and all the answers to mysteries (Oxymoron, gotta be a lot of stupid); but, one with a hunger for knowledge and Truth. Not Holier than Thou! Sorry, the pyramids were created by a well organized people. For your impossible pyramid construction try Ancient Hieroglyphs, you know; the one's before you could count, or read or write, not in English, not translated. Oh, forgot, you can't read it 'cause the library was burned, Down! Who are your so called experts?
