Energy From Thorium: A Nuclear Waste Burning Liquid Salt Thorium Reactor

<http://www.energyfromthorium.com/lftradsrisks.html> _ Successfully developing a liquid-fluoride thorium reactor (LFTR) would essentially solve our planets energy problems for thousands of years, because it would allow us to fully utilize the energy in natural thorium, which makes up 0.0012% of the Earths crust. Most of the research and development work for this technology was done by Oak Ridge National Labs back in the 50s and 60s. They were working to a different set of overall objectives, nevertheless, there are many lessons to be gleaned from their work that can help us to avoid pitfalls and develop LFTR into a high-performance, high-reliability power supply. ___________________ We need to form a consortium to develop a pilot plant to dispose of nuclear waste and generate usable power. Clean the planet to buy the planet!

Liquid Fluoride Thorium Reactor

>http://www.energyfromthorium.com/lftradsrisks.html> _ We need to form a consortium to develop a pilot plant to dispose of nuclear waste and generate usable power. Clean the planet to buy the planet!______________________________ Google Tech Talks November 18, 2008 ABSTRACT Electrical power is, and will increasingly become, the desired form of energy for its convenience, safety, flexibility and applicability. Even future transportation embraces electric cars, trains, and chemical fuel production (jet fuel, hydrogen, etc.) based upon an abundant electrical supply. Although existing energy sources can and should be expanded where practical, no one source has shown to be practical to rapidly fulfill the world's energy requirements effectively. Presently there is an existing source of energy ideally suited to electrical energy production that is not being exploited anywhere in the world today, although its existence and practicality has been know since the earliest days of nuclear science. Thorium is the third source of fission energy and the LFTR is the idealized mechanism to turn this resource into electrical energy. Enough safe, clean energy, globally sustainable for 1000's of years at US standards. This talk is aimed at explaining this thorium energy resource from fundamental physics to today's practical applications. The presentation is sufficient for the non-scientist to grasp the whole subject, but will be intriguing to even classically trained nuclear engineers. By providing the historical context in which the technology was discovered and later developed into a power reactor, the story of thorium's disappearance as an energy source is revealed. But times have changed, and today, thorium energy can be safely exploited in a completely new form of nuclear reactor. The LFTR is unique, having a hot liquid core thus eliminating fuel fabrication costs and the need for a large reactor. It cannot have a nuclear meltdown and is so safe that typical control rods are not required at all. This design topples all the conventional arguments against conventional energy sources in such areas as: * Waste Production * Safety * Proliferation * Capital Costs and Location * Environmental Impact * Social Acceptance * Flexibility * Grid Infrastructure * Efficiency Should America take this step toward a New Era in Nuclear Energy Production? Hear the case for "The Electricity Rock" and then decide. Speaker: Dr. Joe Bonometti Dr. Bonometti has extensive engineering experience in the government, within industry, and in academia over a 25-year career. Recently completing an assignment as the NASA Chair Professor at the Naval Post graduate School, he supported a ship design study that utilized advanced nuclear power derived from thorium. Working at NASA for ten years as a technology manager, lead systems engineer, nuclear specialist, and propulsion researcher, he lead several NASA tiger teams in evaluating the Nuclear System Initiatives fission demonstration vehicle and missions. He managed the Emerging Propulsion Technology Area for in-space systems, the Marshall Air Launch team, as well as a variety of other power and propulsion assignments and is now the Lead Systems Engineer for the Ares I-Y flight. After earning a Doctorate degree in Mechanical Engineering from University of Alabama in Huntsville, he spent several years as a Research Scientist & Senior Research Engineer at the UAH Propulsion Research Center where he served as a Principal Investigator and manager for the Solar Thermal Laboratory. He has worked as a Senior Mechanical Designer at Pratt & Whitney supporting aircraft engine manufacturing and at the Lawrence Livermore National Laboratory within the laser fusion program. A graduate from the United States Military Academy, at West Point, where he studied nuclear physics and engineering, Dr. Bonometti served as an officer in the United States Army Corps of Engineers; both in combat and district engineering management assignments. He is a Registered Professional Engineer in the State of Virginia, and has authored numerous aerospace technical publications, particularly propulsion and space systems technologies. His technical expertise includes nuclear engineering, specialized mechanical & materials research, space plasmas & propulsion, thermodynamics, heat transfer, and space systems engineering. This Google Tech Talk was hosted by Boris Debic.

Strong Photon-Photon Interactions and Meta-Materials

ABSTRACT Fun with Light: Strong Photon-Photon Interactions and Meta-Materials Presented by Jung-Tsung Shen The lightsaber is a supercool gadget that all of us would like to get one. It exhibits many novel light phenomena, notably the light blades of two lightsabers could interact with each other. Unfortunately it takes an enormous amount of energy to achieve that. One of the main difficulties of making a lightsaber is that photons normally do not interact with each other. In the first part of the talk, I will describe how to make photons interact with each other, which enables the capability of using photons to control photons. This capability has many potential applications in quantum communication and information processing, and other novel optoelectronics devices. Moreover, the configuration is well-suited for on-chip all solid-state implementations. In the second part of the talk, I will briefly explain what metamaterials are, and some novel optical tricks they can play, such as Harry Potter's invisibility cloak and super lens. In particular, I will discuss the mechanisms and properties of a special class of metamaterials -- metamaterials with ultra-high refractive index. Such artificial structures will be useful in many applications such as subwavelength lithography and imaging, broadband slow-light, and sensitive interferometer. (* The talk is for general audience with no background in these fields. *) Dr. Jung-Tsung Shen is currently a research associate at Stanford University, working on photon transport in nano-photonics, metamaterials, plasmonics, and thermal and energy transport in nano-structures. He obtained his PhD degree in physics in 2003 from MIT. He was also a graduate scholar at Bell Labs from year 1998 -2001. He will be an assistant professor at Washington University in St. Louis in September this year.

2008 Herzberg Lecture

he 2008 Herzberg Lecture took place November 4, 2008 at Carleton University. Rolf-Dieter Heuer has been designated as the next Director General of CERN, the European Organization for Nuclear Research. He has contributed to the study of electron positron interactions, the development of experimental techniques, and the construction of large detector systems. Despite great success, many key questions in particle physics and cosmology are unanswered. In particular, some 95% of the Universe consists of unknown dark matter and dark energy. Particle physics is about to enter the Terascale, providing a deeper understanding of the Universe and possibly dramatically changing our view of the world. With the start-up of the Large Hadron Collider at CERN this year, we expect revolutionary results explaining the origin of matter, unraveling the nature of dark matter and providing glimpses of extra spatial dimensions or grand unification of forces and hints on dark energy.

The Laws of Sir Isaac Newton

A film I made for my 9th grade science class. If the title isn't revealing enough, it's about Sir Isaac Newton's 3 Laws of Physics. For the record, yes, I realize that I made a mistake with Newton's Second Law. I know that the ball should have been measured in kilograms rather than grams, and that it really should be 2000 m/s^2.
