ABSTRACT
Climate change has multiple direct and indirect consequences for human health. Heat waves affect health directly and are projected to take an increasing toll in developed and underdeveloped nations. The 2003 summer heatwave in Europe — an event six standard deviations from the mean — led to 21-35,000 excess deaths in five nations, extensive wildfires, crop failures, nuclear plant shutdowns and melted 10% of the Alpine glacial mass. This event and Hurricane Katrina in 2005 demonstrate that climate change and its impacts may be surprisingly non-linear. Credits: Speaker:Paul Epstein

ABSTRACT
The World Energy Council has estimated the ‘useful’ global ocean wave energy resource as 2TW (17,500TWh/year). From this it has been estimated (Thorpe 1999) that the practical economic contribution from wave energy converters could be 2,000TWh/year (similar to current installed nuclear or hydroelectric generation capacity). Such generating capacity could result in up to 2 billion tonnes of CO2 emissions being displaced from fossil fuel generation per year – similar to current emissions from electricity generation in the US.

Formed in 1998, based in Edinburgh, Scotland, Ocean Power Delivery Ltd has developed the ‘Pelamis’ wave energy converter…

Dr. Miele is an alumnus of the University of California at Berkeley where he received his BA in Physics and his Ph.D. in Psychoacoustics. He is currently a Research Associate at The Smith-Kettlewell Eye Research Institute’s Rehabilitation Engineering Research Center where he is conducting research in the areas of tactile maps and auditory displays. In the early 1990’s, Dr. Miele was on the development team for Berkeley Systems’ outSPOKEN — the first screen reader that provided a significant level of accessibility for a GUI environment — and has consulted extensively within the access technology industry on a range of issues related to non-visual user…

ABSTRACT
A new ultracapacitor technology from APCT (US-Ukrainian start-up) provides an efficient, low cost means of managing power delivery for applications ranging from hand held devices to hybrid vehicles and power generating systems of all types. When integrated into battery powered devices, the APCT technology can extend battery life by as much as 400%, lowering the cost of batteries and reducing hazardous waste streams. Fast charge/discharge cycling with 95% efficiency improves performance and lowers cost for fuel cell vehicles and hybrid electric automobiles. High energy density and hundreds of thousands of cycles provides critical load leveling…
