Deceleration of runaway electrons paves the way for fusion power

Added: 23.06.2017 11:28 | 0 views | 0 comments

#zrodlo

Fusion power has the potential to provide clean and safe energy that is free from carbon dioxide emissions. However, imitating the solar energy process is a difficult task to achieve. Two young plasma physicists have now taken us one step closer to a functional fusion reactor. Their model could lead to better methods for decelerating the runaway electrons, which could destroy a future reactor without warning.

Corn better used as food than biofuel, study finds

Added: 20.06.2017 14:29 | 0 views | 0 comments

#zrodlo

Corn is grown not only for food, it is also an important renewable energy source. Renewable biofuels can come with hidden economic and environmental issues, and the question of whether corn is better utilized as food or as a biofuel has persisted since ethanol came into use. For the first time, researchers have quantified and compared these issues in terms of economics of the entire production system to determine if the benefits of biofuel corn outweigh the costs.

New metrology technique measures electric fields

Added: 20.06.2017 11:42 | 0 views | 0 comments

#zrodlo

It is crucial that mobile phones and other wireless devices -- so prevalent today -- have accurate and traceable measurements for electric fields and radiated power. Until recently, however, it wasn't possible to build self-calibrating probes that could generate independent and absolute measurements of these. To address this, researchers have developed a method to measure electric fields and a probe to carry out such measurements.

#zrodlo

Modern batteries power everything from cars to cell phones, but they are far from perfect -- they catch fire, they perform poorly in cold weather and they have relatively short lifecycles, among other issues. Now researchers have described a new class of material that addresses many of those concerns in a new article.
