Acousto-optic tunable filter technology for balloon-borne platforms

Thu, 23 Oct 2014 10:07:33 EDT

A balloon-borne acousto-optic tunable filter hyperspectral imager is ideally suited to address numerous outstanding questions in planetary science. Their spectral agility, narrowband wavelength selection, tolerance to the near-space environment, and spectral coverage would enable investigations not feasible from the ground. Example use cases include synoptic observations of clouds on Venus and the giant planets, studies of molecular emissions from cometary comae, the mapping of surface ices on small bodies, and polarimetry.

Home Solar Power Discounts Are Worker Perk in New Program

Thu, 23 Oct 2014 00:00:00 -0400

Conceived at the World Wildlife Fund, the initiative uses bulk purchasing power to allow for discounts on home systems.

Cheaper silicon means cheaper solar cells

Wed, 22 Oct 2014 08:42:50 EDT

Researchers have pioneered a new approach to manufacturing solar cells that requires less silicon and can accommodate silicon with more impurities than is currently the standard. Those changes mean that solar cells can be made much more cheaply than at present.

Researchers patent a nanofluid that improves heat conductivity

Tue, 21 Oct 2014 11:12:35 EDT

Researchers have developed and patented a nanofluid improving thermal conductivity at temperatures up to 400°C without assuming an increase in costs or a remodeling of the infrastructure. This progress has important applications in sectors such as chemical, petrochemical and energy, thus becoming a useful technology in all industrial applications using heat transfer systems such as solar power plants, nuclear power plants, combined-cycle power plants and heating, among other.

Crystallography: Towards controlled dislocations

Mon, 20 Oct 2014 10:53:31 EDT

Scientists have used atomic-resolution Z-contrast imaging and X-ray spectroscopy in a scanning transmission electron microscope to explore dislocations in the binary II-VI semiconductor CdTe, commercially used in thin-film photovoltaics. The results may lead to eventual improvement in the conversion efficiency of CdTe solar cells. These novel insights into atomically resolved chemical structure of dislocations have potential for understanding many more defect-based phenomena.

Keeping Prices Up in a Co-op

Sun, 19 Oct 2014 00:00:00 -0400

Worries over low-priced apartments next door; personal data on co-op applications; and insurance for homes with solar panels.

Austin Plan for Renewable Energy at Odds With Utility

Fri, 17 Oct 2014 00:00:00 -0400

As Austin’s City Council passed legislation to commit to a progressive energy policy, the city-owned utility has balked at the proposal saying it would be too expensive.

Balancing renewable energy costs and optimizing energy mix

Mon, 13 Oct 2014 09:04:47 EDT

Increasing reliance on renewable energies is the way to achieve greater carbon dioxide emission sustainability and energy independence. As such energies are yet only available intermittently and energy cannot be stored easily, most countries aim to combine several energy sources. Scientists have now come up with an open source simulation method to calculate the actual cost of relying on a combination of electricity sources.

Lincoln Center Turns to Solar Power to Provide Some of Its Bright Light

Fri, 10 Oct 2014 00:00:00 -0400

Thirty-six panels have been installed on the roof of the Rose Building in Manhattan, representing another step in a campaign to go green.

How Grid Efficiency Went South

Wed, 08 Oct 2014 00:00:00 -0400

The industry is working to provide an adequate amount of both energy and power at a reasonable cost.

SolarCity Joins Rivals in Lending Solar Panels to Clients

Wed, 08 Oct 2014 00:00:00 -0400

Customers in eight states will be able to buy solar systems with monthly payments based on how much electricity the systems produce.

2014 Nobel Prize in Physics: Invention of efficient blue light-emitting diodes

Tue, 07 Oct 2014 07:17:41 EDT

The 2014 Nobel Prize in Physics has been awarded to Isamu Akasaki, of Meijo University in Nagoya and Nagoya University, Japan; Hiroshi Amano, of Nagoya University, Japan; and Shuji Nakamura of the University of California, Santa Barbara, CA, USA "for the invention of efficient blue light-emitting diodes which has enabled bright and energy-saving white light sources."
