    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...

    Near term Commercial Fusion Power Possible - Laser induced fusion of ultra-dense deuterium with double net energy gain has been produced and gain of 20 times is within reach energy, fusion, laser, materials, nuclear, physics, science Facebook Twitter linkedin google Reddit Researchers at the University of Gothenburg and the University of Iceland are researching a new type of nuclear fusion process. This produces almost no neutrons but instead fast, heavy electrons (muons), since it is based on nuclear reactions in ultra-dense heavy hydrogen (deuterium). The new fusion process can take place in relatively small laser-fired fusion reactors fuelled by heavy...
  • Boeing patent reveals radical 'laser fusion' fission engine design

    Future aircraft could be powered by lasers and nuclear explosions if Boeing has its way. The aerospace firm claims a new-type of engine could produce energy-efficient thrust by firing lasers at radioactive material, such as deuterium and tritium. The technology could mean that planes and spaceships will require only a fraction of the power to operate, according to a recent patent filed by the company.
  • Rosetta Instrument Reignites Debate on Earth's Oceans

    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...
  • Deuterium microbomb rocket propulsion

    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...

    DETROIT — On the surface, Thiago Olson is like any typical teenager. He's on the cross country and track teams at Stoney Creek High School in Rochester Hills, Mich. He's a good-looking, clean-cut 17-year-old with a 3.75 grade point average, and he has his eyes fixed on the next big step: college. But to his friends, Thiago is known as "the mad scientist." In the basement of his parents' Oakland Township, Mich., home, tucked away in an area most aren't privy to see, Thiago is exhausting his love of physics on a project that has taken him more than two...
  • Researchers report bubble fusion results replicated ~ Cold fusion no longer confusion

    BOFFINS FROM the Rensselaer Polytechnic Institute (RPI), Purdue University, Oak Ridge National Laboratory (ORNL), and the Russian Academy of Science (RAS) have managed to replicate controversial cold fusion experiments. A March 2002 an article in Science (Vol. 295, March 2002), indicated that boffins had managed to use bubble fusion successfully, but this data was questioned because it was made with imprecise instrumentation. Now Physical Review E is publishing an article by the team of researchers stating that it has replicated and extended previous experimental results and this time has used the right instruments. Cold fusion is a bit of a...

    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...
