In an effort to stabilize climate and slow down global warming, Livermore scientists along with a team of international researchers have evaluated a series of new primary energy sources that either do not emit or limit the amount of carbon dioxide released to the atmosphere.
Possible candidates for primary energy sources include terrestrial, solar and wind energy; and solar-power satellites; biomass; nuclear fission; nuclear fusion; fission-fusion hybrids and fossil fuels from which carbon has been removed.
In a paper published in the November 1 edition of Science, Livermore researchers Ken Caldeira, L. John Perkins collaborated with a team to survey and evaluate a series of advanced energy technologies for their capability to supply mass amounts of carbon-emission-free energy required and their potential for large-scale commercialization.

Spectrally narrow x-ray pulses may be “sharpened” by purely mechanical means. This sounds surprisingly, but a team of theoretical and experimental physicists developed and realized such a method. It is based on fast motions, precisely synchronized with the pulses, of a target interacting with the x-ray light. Thereby, photons are redistributed within the x-ray pulse to the desired spectral region.
A team of theoretical physicists from the MPI for Nuclear Physics (MPIK) in Heidelberg has developed a novel method to intensify the spectrally broad x-ray...
Physicists working with researcher Oriol Romero-Isart devised a new simple scheme to theoretically generate arbitrarily short and focused electromagnetic fields. This new tool could be used for precise sensing and in microscopy.
Microwaves, heat radiation, light and X-radiation are examples for electromagnetic waves. Many applications require to focus the electromagnetic fields to...
Strong light-matter coupling in these semiconducting tubes may hold the key to electrically pumped lasers
Light-matter quasi-particles can be generated electrically in semiconducting carbon nanotubes. Material scientists and physicists from Heidelberg University...
Fraunhofer IPA has developed a proximity sensor made from silicone and carbon nanotubes (CNT) which detects objects and determines their position. The materials and printing process used mean that the sensor is extremely flexible, economical and can be used for large surfaces. Industry and research partners can use and further develop this innovation straight away.
At first glance, the proximity sensor appears to be nothing special: a thin, elastic layer of silicone onto which black square surfaces are printed, but these...
