GE Technology Selected for Hydrogen Energy IGCC Project in California

Green Car Congress

The Hydrogen Energy California County project would be the first power plant built under that alliance. IGCC also significantly reduces criteria emissions—sulfur dioxide, nitrous oxide, mercury and particulate matter—and decreases water consumption by up to 30% (as compared to a conventional coal plant).

Taking the Measure of the Earthquake That Destroyed Tokyo

Cars That Think

Palmieri’s seismograph consisted of U-shaped tubes filled with mercury. When the ground shook, the mercury would close an electrical circuit and stop an attached clock. At the 1895 International Geographical Congress, Rebeur-Paschwitz proposed setting up a worldwide network of seismological stations.
