The Volume 42, Number 4 • Winter 2012 BRIDGE LINKING ENGINEERING AND SOCIETY Editor’s Note 3 Exploring the Frontiers of Engineering Kristi Anseth Features 5 Overview of Climate Engineering Eli Kintisch Adaptation to climate change may include two types of geoengineering: solar radiation management (SRM) and carbon dioxide removal (CDR). 10 Offsetting Climate Change by Engineering Air Pollution to Brighten Clouds Lynn M. Russell Research shows that the judicious targeting of clouds and selection of the size and composition of particle emissions can produce substantial cooling effects. 16 Keeping Up with Increasing Demands for Electrochemical Energy Storage Jeff Sakamoto Electric vehicles show promise in minimizing reliance on fossil fuels, but their widespread use will likely require a revolutionary advance in energy storage technology. 25 The Car and the Cloud: Automotive Architectures for 2020 Rahul Mangharam Informational needs in automobiles are transcending mechanical, electronic, and software boundaries to include programmed services for the driver and the vehicle itself. 34 Playing to Win: Serious Games for Business Phaedra Boinodiris Gaming techniques can save money, time, and resources while making departments and organizations more agile. 40 Engineering Tissue-to-Tissue Interfaces and the Formation of Complex Tissues Helen H. Lu The successful regeneration of tissue-to-tissue interfaces through a bioinspired approach may enable the translation of tissue engineering technologies from bench to bedside. 48 Engineering 3D Tissue Systems to Better Mimic Human Biology Matthew Gevaert Engineered 3D tissue systems can better mimic human biology and thus meet the growing need for more effective in vitro models.

Two presentations from this session are included in this issue. Eli Kintisch, of Science Magazine, provides an overview of climate engineering and of important considerations before such intervention is undertaken. In the second article, Lynn Russell, a researcher at the Scripps Institute of Oceanography, describes the role of atmospheric aerosols in climate engineering and gives examples of recent field projects that have attempted to shed light on the basic science and physics of cloud Kristi Anseth brightening.
