Innovations in RNA manipulation could lead to advances in many products

Washington D.C. – Researchers at the U.S. Department of Energy's (DOE's) Joint BioEnergy Institute (JBEI) announced today a major breakthrough in engineering systems of RNA molecules through computer-assisted design, which could lead to important improvements across a range of industries, including the development of cheaper advanced biofuels. Scientists will use these new "RNA machines", to adjust genetic expression in the cells of microorganisms. This will enable scientists to develop new strains of Escherichia coli (E. coli) that are better able to digest switchgrass biomass and convert released sugars to form three types of transportation fuels – gasoline, diesel and jet fuels.

Solar power much cheaper to produce than most analysts realize, study finds PDF Print E-mail
Thursday, 08 December 2011 04:34

The public is being kept in the dark about the viability of solar photovoltaic energy, according to a study conducted at Queen’s University.

“Many analysts project a higher cost for solar photovoltaic energy because they don’t consider recent technological advancements and price reductions,” says Joshua Pearce, Adjunct Professor, Department of Mechanical and Materials Engineering. “Older models for determining solar photovoltaic energy costs are too conservative.”

A Fifth of Global Energy Could Come from Biomass Without Damaging Food Production PDF Print E-mail
Saturday, 26 November 2011 03:36

A new report suggests that up to one fifth of global energy could be provided by biomass (plants) without damaging food production.

The report reviews more than 90 global studies. It has been produced by the Technology and Policy Assessment function of the UK Energy Research Centre (UKERC), which addresses key controversies in the energy field, and aims to provide authoritative and accessible reports that set very high standards for rigour and transparency.

Cheaper Yet Efficient Thin Film Solar Cells Created PDF Print E-mail
Sunday, 16 October 2011 22:21
Researchers in Singapore have exploited advanced nanostructure technology to make a highly efficient and yet cheaper silicon solar cell. With this development, the researchers hope that the cost of solar energy can be halved.
 

Developed jointly by Nanyang Technological University (NTU) and A*STAR Institute of Microelectronics (IME), the new thin-film silicon solar cells are designed to be made from cheaper, low grade silicon. However it is able to generate electricity currents close to that produced by traditional solar cells made from costly, high quality silicon.

Solar power development in US Southwest could threaten wildlife PDF Print E-mail
Friday, 09 December 2011 04:57

Environmental impacts of planned installations largely unknown

Government agencies are considering scores of applications to develop utility-scale solar power installations in the desert Southwest of the United States, but too little is known to judge their likely effects on wildlife, according to an article published in the December 2011 issue of BioScience. Although solar power is often seen as a "green" energy technology, available information suggests a worrisome range of possible impacts. These concern wildlife biologists because the region is a hotspot of biodiversity and includes many endangered or protected species, notably Agassiz's desert tortoise. It and another tortoise, Morafka's, dig burrows that shelter many other organisms.

How BP Blew Its Chance to Spearhead a Solar Innovation PDF Print E-mail
Wednesday, 16 November 2011 01:44

The company had a head start on technology that allows solar cells to be manufactured more cheaply, but lost out to Chinese competitors. 

BP has had its share of missteps, including the worst oil spill in history. It may have made another sort of mistake in solar energy—failing to capitalize on an important advance that has now been taken up by Chinese solar-panel makers. The advance could help the Chinese companies maintain their overwhelming lead in the solar industry.

Technology Funding Makes Climate Protection Cheaper PDF Print E-mail
Sunday, 16 October 2011 22:23
To cost-effectively protect the climate, not only an emissions trading scheme but also financial support for new technologies is needed. Economising on targeted funding, for example for renewable energies, makes climate protection more expensive -- as scientists of the Potsdam Institute for Climate Impact Research (PIK) now calculated for the first time, using a complex computer simulation that spans the entire 21st century. Without funding, energy technologies with high cost reduction potentials will hardly stand a chance, since they require a significant initial investment: a case of market failure.

Mobile Electrons Multiplied in Quantum Dot Films PDF Print E-mail
Sunday, 16 October 2011 22:16
Researchers of the Opto-electronic Materials section of the TU Delft and Toyota Europe have demonstrated that several mobile electrons can be produced by the absorption of a single light particle in films of coupled quantum dots. These multiple electrons can be harvested in solar cells with increased efficiency.
 

The researchers published their findings in the October issue of the scientific journal Nano Letters.

A way to increase the efficiency of cheap solar cells is the use of semiconductor nanoparticles, also called quantum dots. In theory, the efficiency of these cells can be increased to 44%.
