High-Altitude Winds Hold Sky-High Promise for Meeting Electricity Needs

Jeff Kart — Tue, 16 Jun 2009 19:54:18 +0000

High-altitude winds hold enough energy to power the world 100 times over.

Though harnessing them is another issue.

You’ve heard of commercial wind turbines in farm fields, offshore turbines on the water, even small wind turbines on the rooftops of homes, but high-altitude winds are also being studied as a potential energy source.

The first-ever study of high-altitude winds by the Carnegie Institution and California State University says winds in the jet stream, about 30,000 feet up, would be the ideal source to exploit. And the sky over New York is a prime spot, along with population centers in the eastern United States and East Asia.

Study Shows Camelina-Derived Renewable Jet Fuel Reduces Carbon Emissions 84%

Renewable fuels company Sustainable Oils shared the results of a life-cycle analysis of jet fuel created from proprietary Camelina seeds. According to the study, renewable jet-fuel made from Camelina reduces carbon emissions by 84% percent compared to the petroleum-based counterpart.

A team at Michigan Tech University based their research on Camelina grown in Montana and then processed into bio-jet fuel using “UOP hydroprocessing technology”. Next generation biofuels are true hydrocarbons and in the molecular aspect are indistinguishable from fossil fuels, which makes Camelina oil a good candidate to quickly reduce carbon emissions produced by aviation.

Biodiesel Powered Plane Makes History With First Flight Across US

Earlier this month, pilots Carol Sugars and Douglas Rodante made history by becoming the first flight-crew to successfully fly across the US in a plane predominantly powered by biodiesel.

Of the total 2,486 miles flown from Reno, Nevada to Leesburg, Florida, 1,776 miles were 100% biodiesel-powered. The remaining 710 miles were powered by a 50/50 mix of biodiesel and standard jet fuel.
