A part of the performance degradation mechanism of the advanced, electrodeless, helicon plasma thruster with a magnetic nozzle, has been revealed. An electric propulsion device is a main engine, and a key piece of technology for space development and exploration. Charged particles are produced by electric discharge and accelerated. Thrust force is equivalent to the momentum exhausted by the device, and spacecraft can thus be propelled.
A new approach to wastewater treatment may be key in efforts to reduce, reuse, and recycle. Moreover, it can be profitable. Phosphorus is an essential element for human nutrition. It plays multiple roles in the human body, including the development of bones and teeth. Fertilizer with phosphorus, applied to crops or lawns, enables healthy growth. Without it, the basic cells of plants and animals, and life itself, would not exist.
The gold standard for modeling the behavior of fusion plasmas may have just gotten better. Mario Podestà has updated the worldwide computer program known as TRANSP to better simulate the interaction between energetic particles and instabilities—disturbances in plasma that can halt fusion reactions. The updates could lead to improved capability for predicting the effects of some types of instabilities in future facilities.
For the first time, industry and policymakers have a comprehensive report detailing the U.S. hydropower fleet’s 2,198 plants that provide about 7 percent of the nation’s electricity. The report is a resource that describes key features of the nation’s hydro resources and systematically tracks trends that have influenced the industry in recent years.
By opening up the possibility of economical asteroid water mining, the electric solar wind sail (E-sail) enables frequent and affordable manned Mars flights. The E-sail is a novel propellantless technology that was invented in Finland in 2006. The E-sail utilizes long, charged tethers to convert natural solar wind momentum flux into spacecraft thrust.
In National Ignition Facility (NIF) inertial confinement fusion (ICF) experiments, the fusion fuel implodes at a high speed in reaction to the rapid ablation, or blow-off, of the outer layers of the target capsule. To reach the conditions needed for ignition, the fuel must implode symmetrically at a peak velocity of about 350 kilometers per second—without producing hydrodynamic instabilities that can dampen the fusion reactions.
The editors of R&D Magazine have announced a deadline extension for the 2015 R&D 100 Awards entry process until May 18, 2015. The R&D 100 Awards have a 50 plus year history of awarding the 100 most technologically significant products of the year.
Immediately following the passage of the Energy Independence and Security Act (EISA) of 2007, much research interest focused on the development of bio-based renewable energy sources (biofuels). EISA mandated increased production and use of biofuels for the long term. There also appeared to be substantial long-term government support for the implementation of a biofuel-based industry.
A cobalt-based thin film serves double duty as a new catalyst that produces both hydrogen and oxygen from water to feed fuel cells, according to scientists at Rice Univ. The inexpensive, highly porous material may have advantages as a catalyst for the production of hydrogen via water electrolysis. A single film far thinner than a hair can be used as both the anode and cathode in an electrolysis device.

A team of Virginia Tech researchers has discovered a way to create hydrogen fuel using a biological method that greatly reduces the time and money it takes to produce the zero-emissions fuel. This method uses abundantly available corn stover to produce the hydrogen. The team's new findings could help speed the widespread arrival of the hydrogen-powered vehicles in a way that is inexpensive and has extremely low carbon emissions.
In a broad new assessment of the status and prospects of solar photovoltaic technology, Massachusetts Institute of Technology researchers say that it is “one of the few renewable, low-carbon resources with both the scalability and the technological maturity to meet ever-growing global demand for electricity.”
Straw-powered cars could be a thing of the future thanks to new research from the Univ. of East Anglia. A new study pinpoints five strains of yeast capable of turning agricultural by-products, such as straw, sawdust and corncobs, into bioethanol. It is estimated that more than 400 billion litres of bioethanol could be produced each year from crop wastage.
The latest generation of halogenated coolants is a big step forward: these substances decay more quickly in the atmosphere hence their lifetimes are considerably shorter. That is why they do not add nearly as much to the greenhouse gas effect as their stable predecessors.
New research published by Rutgers Univ. chemists has documented significant progress confronting one of the main challenges inhibiting widespread utilization of sustainable power: Creating a cost-effective process to store energy so it can be used later.
