Researchers Modify Oilseed To Lower Viscosity For Use As Biodiesel Fuel
Heading into another U.S. presidential election year, getting more biofuels into the U.S. gasoline supply continues to pose both political and logistical hurdles. But researchers, regulators, and entrepeneurs increasingly see promise in synthetic diesel created from a variety of non-fossil fuel...

Even two years ago, about a third of Canadian car buyers were open to buying a plug-in electric car--but they need a lot more practical and real-world information about the options than they're getting. And without sustained and coordinated policy support, those potential buyers may dwindle to the point that electric cars only represent 1 percent of Canadian car sales. Those are the findings of two recent surveys that have now been analyzed in a new study, Electrifying Vehicles: Insights From The Canadian Plug-in Electric Vehicle Study.

HyperSolar Nears Voltage Needed For Solar Hydrogen Production
What's so magical about 1.5 volts, you may ask? It turns out that it's the practical voltage required to produce hydrogen gas from water using artificial photosynthesis, powered only by solar energy, at commercial scale. At least, that's the claim of a startup company called Hypersolar, which two...

Ultra-Efficient BMW Four-Seat Plug-In Hybrid For Research Only, Not Sales: Report
The limited-production Volkswagen XL1 ultra-economy two-seater gets astounding fuel efficiency from its two-cylinder diesel plug-in hybrid powertrain. It's well over 100 miles per gallon if you use the European test cycle (which differs from U.S. tests). But at a six-figure price and a production...

Tesla Not Disruptive, Future Is Tiny Electric 'Golf Carts': Harvard Scholar
Friday's the day we use for the stranger and more oddball stories in our lineup, and one of the more unusual we've seen in a while comes from Harvard University. It's an article--actually a handful of articles--covering research by a scholar of "disruption" who argues that Silicon Valley startup...

The division is pretty clear: nickel-metal-hydride batteries are for use only in hybrids--at least those from Toyota, which has used more of the batteries than any other maker by far. Lithium-ion cells, on the other hands, are the only ones with sufficient energy density to be used in the much larger packs of battery-electric and plug-in hybrid vehicles. That's how it's been for most of a decade.

Why Lithium-Ion Batteries Degrade With Repeated Charging
As anyone with a smartphone, laptop or indeed a whole electric car will know, lithium-ion batteries degrade over time. Each time you charge and discharge the batteries, they lose a little capacity. Day to day you don't really notice, but over a year, or two, it means being able to use your phone...
