    Helion Energy, a startup developing engines powered by nuclear fusion, is certain to pique the interest of sci-fi fans. But the more important question for Helion President Philip Wallace is whether the same can be said of venture capitalists. That’s because the Seattle-based company is on the hunt for $20 million in financing to build a full-scale model of its fusion engine. That engine, which the company currently has a prototype of at one-third scale, works by forming hot, ionized hydrogen gas. The gas is then electromagnetically accelerated to greater than 1 million mph and collided in a burn chamber...

    NASA’S NEW SHORTCUT TO FUSION POWER Lattice confinement fusion eliminates massive magnets and powerful lasers PHYSICISTS FIRST SUSPECTED more than a century ago that the fusing of hydrogen into helium powers the sun. It took researchers many years to unravel the secrets by which lighter elements are smashed together into heavier ones inside stars, releasing energy in the process. And scientists and engineers have continued to study the sun’s fusion process in hopes of one day using nuclear fusion to generate heat or electricity. But the prospect of meeting our energy needs this way remains elusive. The extraction of energy...

    Inside JET's torus, with superimposed plasma. (UKAEA) Late last century, the Joint European Torus (JET) near Oxford, UK, churned out 22 megajoules of energy in what was, at the time, a record in fusion power. Now, experimental upgrades have brought the facility into line with the technology anticipated for a major international project, resulting in the production of nearly three times that amount of power. The advances are a major step forward for tokamak-based fusion, bringing us ever closer to a balance point where we can harvest a near endless stream of energy without the cost of polluting emissions or...
  • Scientists may have discovered unexpected cosmic origin of Earth's water

    Five billion years ago, the universe was Earth-less. It remained that way till a vast number of asteroids smashed together and compacted into a giant rocky orb. But that raises a question: The Earth's surface is 70% water, so where'd the liquid come from? A long-standing theory is that a water-rich class of asteroids, called carbonaceous or C-type asteroids, could've pelted the Earth during its creation and brought along water. There's a caveat though, and the C-type asteroids may be only half the story....
  • Astronomy Picture of the Day - A High Cliff on Comet Churyumov-Gerasimenko

    APOD.NASA.gov ^ | 28 Nov, 2021 | Image Credit & Licence: ESA, Rosetta spacecraft, NAVCAM; Additional Processing: Stuart Atkinson
    Explanation: This high cliff occurs not on a planet, not on a moon, but on a comet. It was discovered to be part of the dark nucleus of Comet Churyumov-Gerasimenko (CG) by Rosetta, a robotic spacecraft launched by ESA that rendezvoused with the Sun-orbiting comet in 2014. The ragged cliff, as featured here, was imaged by Rosetta in 2014. Although towering about one kilometer high, the low surface gravity of Comet CG would likely make it an accessible climb -- and even a jump from the cliff survivable. At the foot of the cliff is relatively smooth terrain dotted with...

Ota Iwate University, Morioka, Japan E-mail: narita@iwate-u.ac.jp It has been reported that anomalous excess heat generation have been observed when charging deuterium into nano-composite Pd-Ni supported by ZrO2 [1,2]. It is supposed to be difficult to explain the phenomena by known chemical processes, which could potentially be attributed to specific characteristics of deuterium diffusion in the metal complex, as well as the nano-sized fine structure of the sample.

    Fusion power is the technology that is 30 years away, and always will be, according to skeptics, at least. Despite its difficult transition into a reliable power source, the nuclear reactions that power the sun have a wide variety of uses in other fields. The concept fusion drive, called a direct fusion drive (or DFD), is in development at the Princeton Plasma Physics Laboratory (PPPL). Though still under development, the engine itself exploits many of the advantages of aneutronic fusion, most notably an extremely high power-to-weight ratio. The fuel for a DFD drive can vary slightly in mass and contains...

    Research reveals that plate tectonics started on Earth 600 million years before what was believed earlier... Where it was previously thought that plate tectonics started about 2.7 billion years ago, a team of international scientists used the microscopic leftovers of a drop of water that was transported into the Earth's deep mantle - through plate tectonics - to show that this process started 600 million years before that. An article on their research that proves plate tectonics started on Earth 3.3 billion years ago was published in the high impact academic journal, Nature, on 16 July... For their research, the...

    Posted on November 9, 2018November 9, 2018 by Evan Gough Not all the Earth’s Water Came From Comets We have comets and asteroids to thank for Earth’s water, according to the most widely-held theory among scientists. But it’s not that cut-and-dried. It’s still a bit of a mystery, and a new study suggests that not all of Earth’s water was delivered to our planet that way.Hydrogen is the most abundant element in the universe, and it’s at the center of the question surrounding Earth’s water. This new study was co-led by Peter Buseck, Regents’ Professor in the School of...

    NASA ^ | 12/10/14
    The question about the origin of oceans on Earth is one of the most important questions with respect to the formation of our planet and the origin of life. The most popular theory is that water was brought by impacts of comets and asteroids. Data from the Rosetta Orbiter Spectrometer for Ion and Neutral Analysis (ROSINA) instrument aboard the European Space Agency’s Rosetta spacecraft indicate that terrestrial water did not come from comets like 67P/Churyumov-Gerasimenko. The findings were published today in the journal Science. Researchers agree that water must have been delivered to Earth by small bodies at a later...

    Abstract: Large scale manned space flight within the solar system is still confronted with the solution of two problems: 1. A propulsion system to transport large payloads with short transit times between different planetary orbits. 2. A cost effective lifting of large payloads into earth orbit. For the solution of the first problem a deuterium fusion bomb propulsion system is proposed where a thermonuclear detonation wave is ignited in a small cylindrical assembly of deuterium with a gigavolt-multimegampere proton beam, drawn from the magnetically insulated spacecraft acting in the ultrahigh vacuum of space as a gigavolt capacitor. For the solution...

    WEST LAFAYETTE, Ind. – Researchers at Purdue University have new evidence supporting earlier findings by other scientists who designed an inexpensive "tabletop" device that uses sound waves to produce nuclear fusion reactions. The technology, in theory, could lead to a new source of clean energy and a host of portable detectors and other applications. The new findings were detailed in a peer-reviewed paper appearing in the May issue of the journal Nuclear Engineering and Design. The paper was written by Yiban Xu, a post-doctoral research associate in the School of Nuclear Engineering, and Adam Butt, a graduate research assistant in...

    A widely criticized effort three years ago to create low-cost tabletop nuclear fusion could gain new support following an experiment at Purdue University. Taking the basic apparatus used in 2002, two Purdue researchers refined the experiment and published new results that once again seem to prove that nuclear fusion was taking place. If it proves to be real, the new approach might lead to a genuine new source of energy. An inexpensive, practical method of controlling nuclear fusion could revolutionize energy production, so any hint of a breakthrough in that direction generates high interest among both the technical community and...
