A perspective article published last month by University of California, Riverside chemists in the Journal of Physical Chemistry Letters was selected as an Editors Choice — an honor only a handful of research papers receive. The perspective reviews the chemists’ work on “singlet fission,” a process in which a single photon generates a pair of excited states. This 1->2 conversion process, as it is known, has the potential to boost solar cell efficiency by as much as 30 percent.
In Washington, the U.S. Department of Energy announced up to $11.3 million for three projects that support the development of biomass-to-hydrocarbon biofuels conversion pathways that, as the DOE remarked, “can produce variable amounts of fuels and/or products based on external factors, such as market demand.”
Despite seeing a slight decline in module shipments, CdTe giant First Solar still led the market in 1Q10, according to calculations from IMS Research.
Europe may be the big end-market for solar PV demand (at least for now), but from a manufacturing standpoint Asian firms are beginning to dominate.
Ben & Jerry's, the Vermont based ice cream company known for its social activism and quirky founders, will support the construction of a new wind turbine in South Dakota through it's participation in a green energy credit program.
Since I'm writing this over the holiday season, the spirit of Charles Dickens is very much present. I've even seen some observers noting the Dickensian flavor of the infamous names -- Madoff and Blagojevich -- dominating the news headlines in late December. So forgive me, in looking at what the New Year is likely to bring for the clean tech industry, for indulging in that oft-quoted line once penned by Dickens:
Cobalt Technologies this week said that it has made a breakthrough in producing biobutanol from beetle-killed lodgepole pine feedstock. Cobalt claims to be the first company to produce a drop-in replacement for petroleum and petrochemicals from beetle-affected lodgepole pine.
Terpenes rarely make the nightly news, but these organic hydrocarbon byproducts of eucalyptus, pine, bacteria and even some species of butterflies and termites are emerging as energy-dense players in the energy biojet and biodiesel markets.
There are six oddly-named streams in the bioeconomy, and it reminds one of the nomenclature of subatomic quarks. There is upstream, midstream, downstream, main-stream, waste-stream, and slip-stream. But of all the streams, perhaps there is nothing so vital yet muddled as the identity of the mainstream and that of the slipstreams.
I am currrently an undergrad in Electrical Engineering, and I just switched majors from Materials Engineering because I felt like I would have a better knowledge of renewable energy. Was this a good move? Christa I, Birmingham, Alabama
