Nanowire generates power by harvesting energy from the environment
As the sizes of sensor networks and mobile devices shrink toward the microscale, and even nanoscale, there is a growing need for suitable power sources. Because even the tiniest battery is too big to be used in nanoscale devices, scientists are exploring nanosize systems that can salvage energy... view more (2007-09-28)

Keeping an eye on fatigue in wind turbines
Wind farms are springing up everywhere like mushrooms. Business in this alternative sector of the energy industry is booming, thanks in part to federal and former state subsidies. The total output of the wind turbines installed in Germany today is theoretically enough to supply the whole capital of... view more (2003-09-18)

A CAR THAT RUNS ON FRESH AIR - ALMOST!
Karl's car finished 38th in a field of 109 entrants - an impressive feat by any standards. 'I built the car over a year as an A level technology project,' says Karl. 'The project was sponsored by Marine Projects at Lee Mill in Plymouth and the team consisted of myself and a friend, Sam Starmore,... view more (1999-02-01)

Energy network launches international web survey
A European website designed to stimulate informed debate on future energy sources this week launches a multi-lingual survey to gauge public attitudes to, and knowledge of, crucial energy issues. The INTUSER website (www.intuser.net) is a new on-line forum for both the general public and energy... view more (2002-12-04)

Optimising the control of wind generators by means of intelligent microsensors

A giant wind-powered generator
The new TWT-1650 wind-powered generator presented in Pamplona has 36-metre vanes which, in a circular movement, sweep an area greater than that of a football pitch and which can withstand extremes of weather, including winds of up to 110 kilometres an hour. This device, made by Grupo Mtorres in... view more (2003-10-14)

Quantum analog of Ulam's conjecture can guide molecules, reactions
Like navigating spacecraft through the solar system by means of gravity and small propulsive bursts, researchers can guide atoms, molecules and chemical reactions by utilizing the forces that bind nuclei and electrons into molecules (analogous to gravity) and by using light for propulsion.   view more (2007-08-08)

Disorder enables extreme sensitivity in piezoelectric materials
A research team working at the National Institute of Standards and Technology (NIST) has found an explanation for the extreme sensitivity to mechanical pressure or voltage of a special class of solid materials called relaxors.   view more (2008-05-19)

Harrowing bowel preparation is unnecessary before colorectal surgery
Research news from The Cochrane Library Surgeons and other experts have long regarded mechanical bowel preparation to be an essential preventative measure before colorectal surgery. Recent evidence in The Cochrane Library, however, reveals that mechanical bowel cleansing does not significantly... view more (2003-10-20)

Bridging the gap - mechanical support could increase survival of children requiring heart transplantation (pp 1948, 1967)
Embargoed 0001 h (London time) 12 December 2003. Fewer children should die while waiting for a heart transplant if they are given mechanical heart support before transplantation, conclude authors of a UK study in this week's issue of THE LANCET. Short-term mechanical heart support has potential... view more (2003-12-10)

"Heftier" Atoms Reduce Friction at the Nanoscale, Study Led By Penn Researcher Reveals
A research team led by a University of Pennsylvania mechanical engineer has discovered that friction between two sliding bodies can be reduced at the molecular, or nanoscale, level by changing the mass of the atoms at the surface.   view more (2007-11-02)
