Cornell-developed tools to guide and switch light could lead to photonic microchips and practical home fiber-optic lines

A Cornell University researcher is developing techniques for making photonic microchips — in which streams of electrons are replaced by beams of light — including ways to guide and bend light in air or a vacuum, to switch a beam of light on and off and to connect nanophotonic chips to optical fiber.

Michal Lipson, an assistant professor at Cornell, in Ithaca, N.Y., described recent research by the Nanophotonics Group in Cornell’s School of Electrical and Computer Engineering at the a

New reactor puts hydrogen from renewable fuels within reach

The first reactor capable of producing hydrogen from a renewable fuel source–ethanol–efficiently enough to hold economic potential has been invented by University of Minnesota engineers. When coupled with a hydrogen fuel cell, the unit–small enough to hold in your hand–could generate one kilowatt of power, almost enough to supply an average home, the researchers said. The technology is poised to remove the major stumbling block to the “hydrogen economy”: no free hydrogen exists, except what is ma

Los Alamos leading fast-paced reactor research to power planned journey to Jupiter’s icy moons

A proposed U.S. mission to investigate three ice-covered moons of Jupiter will demand fast-paced research, fabrication and realistic non-nuclear testing of a prototype nuclear reactor within two years, says a Los Alamos National Laboratory scientist.

The roots of this build and test effort have been under way at Los Alamos since the mid-1990s, said David Poston, leader of the Space Fission Power Team in Los Alamos’ Nuclear Design and Risk Analysis Group.

A strong European technology partnership to move towards the hydrogen economy

European Commission President, Romano Prodi, today launched the “European Hydrogen and Fuel Cell Technology” Platform, whose Advisory Council includes key players of the European hydrogen sector, at its first assembly in Brussels. The Platform has the task of drafting a blueprint to smooth the EU’s transition from a fossil fuel-based to a hydrogen-based economy. The creation of this platform follows the presentation of a report by an EU high-level expert group on June 16, 2003, and the inclusion of

Snezhinsk breakthrough

The first Russian power system based on a solid-oxide fuel cell is tested in Snezhinsk. By importance, this event is comparable with the first automobile construction.

The first Russian power system based on a solid-oxide fuel cell had been tested in the All-Russia Research Institute of Technical Physics (Russian Federal Nuclear Center, Snezhinsk, Chelyabinsk oblast). In this system, hydrogen is obtained from natural gas, and oxygen – from the air. For the first time, such a system ha

Nanostructured sensors for the United States’ company NanoSonic

A research team from the Department of Electric and Electronic Engineering at the Public University of Navarre has designed nanostructured optical sensors and instrumentation to monitor these sensors, for the United States’ company NanoSonic, which has begun to market the product.

The optic fibre sensors are human hair-sized devices. The Public University of Navarre has developed a humidity sensor and a light source for applications with optic fibre sensors. Moreover, the Navarre team has
