The supply of secure, clean, sustainable energy is arguably the most important scientific and technical challenge facing humanity in the 21st century. Rising living standards of a growing world population will cause global energy consumption to double by mid-century and triple by the end of the century. Even in light of unprecedented conservation, the additional energy needed is simply not attainable from long discussed sources these include nuclear, biomass, wind, geothermal and hydroelectric. The global appetite for energy is simply too much. Petroleum-based fuel sources (i.e., coal, oil and gas) could be increased. However, deleterious consequences resulting from external drivers of economy, the environment, and global security dictate that this energy need be met by renewable and sustainable sources. The dramatic increase in global energy need is driven by 3 billion low-energy users in the non-legacy world and by 3 billion people yet to inhabit the planet over the next half century. The capture and storage of solar energy at the individual level personalized solar energy drives inextricably towards the heart of this energy challenge by addressing the triumvirate of secure, carbon neutral and plentiful energy. This talk will place the scale of the global energy issue in perspective and then discuss how personalized energy (especially for the non-legacy world) can provide a path to a solution to the global energy challenge. Daniel G. Nocera is the Henry Dreyfus Professor of Energy at the Massachusetts Institute of Technology, Director of the Solar Revolutions Project and Director of the Eni Solar Frontiers Center at MIT. His group pioneered studies of the basic mechanisms of energy conversion in biology and chemistry. He has recently accomplished a solar fuels process that captures many of the elements of photosynthesis outside of the leaf. This discovery sets the stage for a storage mechanism for the large scale, distributed, deployment of solar energy. He has b

Cisco predicts more than 15 billion network-connected devices by 2015, reaching 966 exabytes (10^18 bytes) per year - close to 1 zettabyte (10^21 bytes). Average global IP traffic in 2015 will reach 245 terabytes per second, equivalent to 200 million people streaming an HD movie (1.2 Mbps) simultaneously. This growth will primarily be driven by the global online video community, which will increase by approximately 500 million users by 2015, up from more than 1 billion Internet video users in 2010, Cisco says. Global IP traffic growth is driven by four primary factors, according to Cisco: An increasing number of devices: The proliferation of tablets, mobile phones, connected appliances and other smart machines is driving up the demand for connectivity.  By 2015, there will be nearly 15 billion network connections via devices - including machine-to-machine - and more than two connections for each person on earth. More Internet users: By 2015, there will be nearly 3 billion Internet users - more than 40 percent of the world's projected population. Faster broadband speed: The average fixed broadband speed is expected to increase four-fold, from 7 megabits per second in 2010 to 28 Mbps in 2015. The average broadband speed has already doubled within the past year from 3.5 Mbps to 7 Mbps. More video: By 2015, 1 million video minutes -+ the equivalent of 674 days - will traverse the Internet every second. By 2015, the Asia Pacific region will generate the most IP traffic (24.1 exabytes per month), surpassing last year's leader, North America (22.3 exabytes per month), for the top spot. The fastest-growing IP-traffic regions for the forecast period (2010-2015) are the Middle East and Africa, surpassing last year's leader, Latin America.

"Someone wishing to access the military base could hack the defense contractor, steal the iris code, reconstruct the iris, print it to a contact lens, and access the military facility. It's all very Mission Impossible, but according to the research, it's not so very far-fetched."
