Control of Ultrafast Energy Transport in Photosynthetic Light Harvesting

submitted by: icamvid

Wendel Wohlleben gives a talk at the ICAM 2007 conference about the light harvesting dynamics at low and high energy regime and SRS enhancing Tannor-Rice-Control on Carotenoid.

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.

The Economics just aren't there: Towards a Model of Wind Energy Industry Development in Industrial and Emerging Economies

submitted by: RASEIBoulder
Summary: Through the development and analysis of in-depth case studies of the emergence of wind power industries in industrialized and emerging economies, a model of sustainable energy industry development is proposed. The model demonstrates that fundamental economic indicators are insufficient for explaining new industry development. Environmental, institutional and cultural factors idiosyncratic to individual jurisdictions play important roles in the emergence of renewable energy...

U.S. Wind Energy Challenges and Opportunities

submitted by: RASEIBoulder
Robert Gramlich is Senior Vice President of Public Policy for the American Wind Energy Association, the national trade association of approximately 2,500 entities involved in all aspects of wind energy production, based in Washington D.C. Rob joined AWEA in 2005 and now leads the association’s strategic initiatives related to federal and state legislation, industry information and analysis, and regulatory policy. He has published articles on wind integration, carbon taxes, market power...

Using Renewable Hybrid Power Systems to Meet Off-Grid Community and Commercial Energy Needs

submitted by: RASEIBoulder
Summary: Diesel generators are the traditional means by which people generate electricity in remote locations. Throughout the world, there are many thousands of off-grid communities, industrial sites, and government facilities relying entirely on diesel generated electricity. At $4/gallon, the fuel component alone of diesel-generated electricity is high, about $0.30/kWh. Some remote locations pay over $8/gallon or $0.60/kWh. With diesel fuel prices projected to rise even higher in the long...

Photo-Physics and Renewable Energy Applications of Single-Walled Carbon Nanotubes

submitted by: RASEIBoulder
Summary: Single-walled carbon nanotubes (SWNTs) are two-dimensionally confined quantum wires that have the potential to impact a variety of renewable energy applications. SWCNTs have several fundamental properties that make them attractive for sustainable energy conversion technologies, including high electron and hole mobilities, size-tunable ionization potentials and electron affinities in an energy range relevant to many photovoltaic devices, and optical transitions in the visible and...

CHALK TALK: ELECTROMAGNETIC RADIATION

submitted by: nsf

Electromagnetic radiation (ER) is a form of energy, and it acts like a wave as it moves at the speed of light--it’s how energy from the sun reaches Earth. ER is classified by frequency—how many times the wave oscillates in a given amount of time.

CHALK TALK: MITOCHONDRIA

submitted by: nsf

This episode of Chalk Talk gives viewers a look inside the "power plant" of most complex cells. Mitochondria provide energy for cells to move, divide, and do all the things they need to do to function properly. Mitochondria are found within almost all living organisms with complex cell structures.

Clean Energy and the Environment in America: The Colorado Story

submitted by: RASEIBoulder
The Center’s Director, Bill Ritter, was elected as Colorado’s 41st governor in 2006 - the first Colorado-born governor in more than 35 years. He quickly established Colorado as a national and international leader in clean energy by creating a New Energy Economy and tripling the state’s renewable energy portfolio. In a state with substantial fossil energy as well as renewable energy resources, Gov. Ritter created policies that balanced energy production with protection of air, land,...

SCIENCE OF THE WINTER OLYMPICS: SCIENCE OF SKATES

submitted by: nsf

The ice skates worn by this year's hockey players, figure skaters and speed skaters are vastly different from what were once used. Melissa Hines, the Director of the Cornell University Center for Materials Research, and Sam Colbeck, a retired scientist from the U.S. Army Cold Regions Lab, explain how innovations in boot and blade design help skaters perform better than ever before.
