Nanogenerator: Vibration Energy The Secret To Self-powered Electronics


Incorporated directly into a cell phone housing, the team's nanogenerator could harvest and convert vibration energy from a surface, such as the passenger seat of a moving vehicle, into power for the phone. The device is described as a "mesoporous piezoelectric nanogenerator". A multi-university team of engineers has developed what could be a promising … [Read more...]

Heavy Satellite Launch Vehicles: An Assessment

Cryogenic Engines

A satellite launch vehicle (rocket) is designed to lift a satellite from the earth and to deliver it to the desired orbit. The strength of such a vehicle depends on the weight of the satellite and the nature of the orbit in which it is to be placed. With advancing rocket technology, capability to put the heavy satellites into different orbits has increased … [Read more...]

Jupiter’s Icy Moon Explained


Under its hard crust of ice, Europa is thought to host an ocean of liquid water, up to 106 miles (170 kilometers) deep. Tides caused by nearby Jupiter could be warming Europa's ocean, providing energy that could be driving an ecosystem of alien life forms. Europa has been explored in many science fiction stories and films, including "Space Odyssey: Voyage … [Read more...]
