August 21, 2008 presentation by Stacey Bent for the Stanford University Office of Science Outreach's Summer Science Lecture Series.
Meeting the world's growing energy needs in a sustainable fashion is one of the most pressing problems of our time. Professor Bent introduces the scope of the energy problem and some of the options for sustainable energy, then will focus on two main devices: solar cells and fuel cells. Solar cells convert the energy of the sun directly into electricity, while fuel cells convert chemical energy directly into electricity. Current research at Stanford is studying the use of new materials to develop the next generation of solar cells and fuel cells.
The Stanford Summer Science Lecture Series is a set of informal lectures about cutting edge research from four of Stanford's most esteemed professors.

A US report has revealed that the campaign of assassination drone attacks in Pakistan\'s northwestern tribal belt is terrorizing civilians 24 hours a day and breeding bitter anti-American sentiment.
Men, women and children are subjected to almost constant trauma -- including fear of attack, severe anxiety, insomnia and high levels of stress -- says the new report by law professors at Stanford and New York Universities.
The nine month investigation into the CIA assassination drones, which is based on public data including interviews with civilians, witnesses and survivors of the US assassination drone attacks in northwest Pakistan indicate that the attacks have killed thousands of people since the beginning, with only 2% of those killed in the attacks begin the militants.
