Detecting earthquakes from Space
Article Abstract:
Scientists have recently tapped the potential of analyzing the ionosphere in detection of earthquakes and other ground rumblings through utilization of Global Positioning System, complementing the conventional seismographic techniques. This network of satellites can obtain data based on the electron density of the atmosphere at a given altitude through sending radio signals to ground-based receivers. Any displacement of the ground from earthquakes, quarry, rocket launches and explosions propagates waves that cause ionospheric electron density disturbance.

Heavenly highways for cyclists
Article Abstract:
Proposals for the construction of an elevated four-lane commuter bikeway called, TransGlide 2000 and EcoTrack easy-installation transportation path, are on the way to ensure safety among cyclists. Milnor Senior, head of Bicycle Transportation Systems, also proposes the construction of enclosed one-way tunnels with installed fans to reduce the air resistance commonly encountered by cyclists. Funds needed for the project are still impending but negotiations with the National Park System for a test track at a US park is ongoing.

The Zeppelin also rises
Article Abstract:
Transport designers are conceptualizing gigantic blimps that could carry any load anywhere, with more capacity and at higher speeds compared to seafaring container ships. One popular design, called the skytrain, links several blimps together, which designers claim offers more advantages than the conventional single blimp. At the forefront of this concept is the Pan Atlantic Aerospace Corp in Ottawa headed by Fredrick Ferguson, which has built and flown two 50-foot prototypes of a 1,500-foot design.
