Charge Car Project Converts Used Cars to Basic Electric Commuter Vehicles

The underlying goal of the ChargeCar project is to examine the common urban commute and to determine if cars powered by managed supercapacitor-battery systems are a solution that can reduce cost of ownership for a commuter car. This is not through the development of new component technologies but by better understanding of real urban commutes …

Breakthrough Will Enable Devices With Electrically and MagneticallyTunable Superconductor Properties

Using precision techniques for making superconducting thin films layer-by-layer, physicists at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory have identified a single layer responsible for one such material’s ability to become superconducting, i.e., carry electrical current with no energy loss. The technique, described in the October 30, 2009, issue of Science, could be …

Artificial General Intelligence, Automation and Economics

J Storrs Hall points out employment test for Artificial General Intelligence that was suggested by Nils Nilsson AI programs must be able to perform the jobs ordinarily performed by humans. Progress toward human-level AI could then be measured by the fraction of these jobs that can be acceptably performed by machines. The list of jobs …
