Green Revolution: Biomass

submitted by: nsf

Explore how different types of biomass can be used to produce fuel. One researcher is building reactors to grow algae used to create biofuel. Another studies how leafcutter ant colonies break down biomass in order to solve a different biofuel problem: conversion of cellulose in plants to a fermentable sugar used to make ethanol. Finally, an engineer shows us how his lab uses chemistry and heat to turn sawmill waste into bio-oil and gasoline.

Is the Sky the Limit for Wind Power?

submitted by: johnstrom
In the future, will wind power tapped by high-flying kites light up New York? A new study by scientists at the Carnegie Institution identifies New York as a prime location for exploiting high-altitude winds, which globally contain enough energy to meet world demand 100 times over. The researchers found that the regions best suited for harvesting this energy match with population centers in the eastern U.S. and East Asia, but fluctuating wind strength still presents a challenge for exploiting...

World Changing Ideas: The Global Energy Transformation Institute

submitted by: BuzzBinder
This original video, produced for the "Scientific American World Changing Ideas Video Contest," features Global Energy Transformation Institute (GETI) Founder Mats R. Larsson and information related to how GETI's approach to global energy management is often overlooked yet necessary. The Global Energy Transformation Institute's mission is as follows: "The Global Energy Transformation Institute (GETI) was founded in 2007 to identify challenges and solutions with large-scale energy...

Sky WindPower's Flying Electric Generators

submitted by: Len Shepard
The video shows the concept, benefits and progress of developing flying electric generators to convert the persistent and abundant power in high altitude winds (aka the jet stream) into electricity. It includes interviewers with inventors Dr. Bryan Roberts, who originally conceived the idea, David Shepard, who convinced Dr. Roberts to jointly form Sky WindPower, and the engineers who are building and testing prototypes today. The video shows an actual runway tow test where electricity was...

Green Fuel = Economic Development

submitted by: daochienergy
This video postulates that by creating "green fuel" cultivation and integrated processing facilities that take waste products from each other as feedstock (including algae & jatropha, anaerobic digesters, manure & wastewater processing, gasifiers, fish farms, dairy farms, and electric generating) that each becomes an independent, secure source of local energy (renewable gasoline, renewable diesel and renewable jet fuels) and expands the commercial reach for both products and raw...

Combining Agriculture with Microbial Genomics To Make Fuels

submitted by: MicrobeWorld
Summary *Key challenges include dealing with diverse cellulosic sugars and finding ways to recycle carbon dioxide back into useful biomass. *Sugar cane and Hibiscus varieties from the Malvaceae plant family are sources of cellulosic biomass that do not require highly productive agricultural lands. *Microorganisms associated with termites and shipworms might harbor useful enzymes for processing biomass, while yeasts associated with Malvaceae plants are also worth investigating....
