The Corpus Callosum

The Corpus Callosum is an occasional journal of armchair musings, by a suburban, reality-based, slightly-left-of-center guy, who reserves the right to be highly irregular at times. Topics: social commentary, neuroscience, politics, science news. Mission: to develop connections between hard science and social science, using linear thinking and intuition; and to explore the relative merits of spontaneity vs. strategy.

Corpus Callosum is written by a psychiatrist at a small community hospital somewhere in the USA. Email to cc.scienceblogger at gmail dot com.

Energy Conversation Efforts

Category: EnergyEnvironment
Posted on: September 4, 2007 8:04 AM, by Joseph j7uy5

IBM is launching Project Big Green.  Part of the initiative is to consolidate operations in the world's largest data centers.  They will replace nearly  4,000 servers with 30 refrigerator-sized System Z mainframes, running Linux, using virtualization technology.  This will reduce energy usage by about 80%, saving about $250 million per year.  

What's more, the consolidation will leave plenty of room for future expansion.

The University of New Hampshire is going to connect its campus to a methane-producing landfill, generating energy using methane that otherwise would be vented into the atmosphere.  The project is expected to provide 85% of their energy needs.  Because it is using carbon that would be going into the atmosphere anyway, it is considered carbon-neutral.  

The U.S. Federal Energy Regulatory Commission has changed its regulations for installation of tidal energy systems.  The regulatory structure had been so cumbersome that it effectively prevented the exploitation of this environmentally-friendly resource.  It is estimated that this could eventually satisfy 6.5 percent of total US energy demand.

Progress is being made in the commercialization of lithium-ion batteries for automobiles.  It is hoped that the products will be on the road in quantity by 2009.  

Lithium-ion batteries provide twice the energy density (energy per kilogram) of current technology, leading to much greater efficiency.

Currently, the only car to use lithium-ion batteries is the Tesla Roadster, costing over $100,000.

European regulators have approved a project that is hoped will lead to commercial development of nuclear fusion power.
