Re-evaluating The Hubbert Curve And The Global Petroleum Revolution: A New Era - Details

submitted by: RASEIBoulder
Summary: Why have the predicted global oil and natural gas shortages and demise of civilization by 2010 related to these vanishing supplies not occurred? The static view has created a pessimistic outlook based on historical perspective such as the Hubbert curve analysis which results in the inescapable and inevitable depletion that will result in catastrophic consequences for civilization. A new paradigm, a dynamic or petroleum system view demonstrates a different and more optimistic...

PLoS Biology: Converging Currents in Climate-Relevant Conservation: Water, Infrastructure, and Institutions

submitted by: johoma
The conservation community has not fully accounted for the implications of climate change to our work, which has become integrated with economic development in recent decades. Many of the largest impacts on ecosystems and species come from infrastructure investments, especially water infrastructure. Given the sensitivity of the water cycle to climate change, there is a high risk of long-lived water infrastructure developing such severe mismatches with its ambient climate that the investment...

Phase-shift Plasma Turbine - Interplanetary Spaceflight

submitted by: MFerreiraJr
The Phase-shift Turbine consists of a set of concentric coils, axially rotated from each other, and feed by phased RF sources, producing radial and longitudinal sequences, which results in helical moving force, ionizing intake gas/particle/ion, generating continuous unidirectional thrust. It was designed in order to operate in atmospheric environments, mainly during takeoff, and in space to reuse exhaust gases from chemical rockets to booster the overall ISP, enhancing utilization of both...
