Physics World magazine: October 2009 special issue
Download a sample copy of a special issue of Physics World magazine that tackles the energy puzzle. The focus of the issue is energy and climate change, with the former BP chief executive Lord Browne, who originally trained as a physicist, arguing that the biggest barriers to a low-carbon economy are not scientific or technological but political. Check out how climate models are becoming more useful to policymakers, plus the materials-science challenges standing between us and clean, long-lasting energy. Read about why scientists need to do a better job of alerting the world to the dangers of global warming and discover how in the future we could all be connected to a hydrogen SuperGrid.
