Most large wind turbines currently operate at variable speeds. When the wind is strong, the rotor turns fast; when it slows down, the rotor speed drops. Typically rotors complete 12…
In the developing world, reducing greenhouse gas emissions is often seen as being in conflict with alleviating poverty, since improving the standard of living is usually associated…
The widespread use of true random number generators (TRNGs) has taken a step closer following the creation of the most lightweight designs to date by researchers at Queen's University…
Behind every coincidence lies a plan - in the world of classical physics, at least. In principle, every event, including the fall of dice or the outcome of a game of roulette, can be…
According to a study presented at SNM's 57th Annual Meeting, a new radioisotope generator could enhance images produced by a molecular imaging technique known as positron emission tomography…
For over 20 years, Fraunhofer IPM has been researching in the field of gas and fluid measurement techniques. Semiconductor sensors, spectrometers as well as components from the Institute…
By combining a new generation of piezoelectric nanogenerators with two types of nanowire sensors, researchers have created what are believed to be the first self-powered nanometre-scale…
A unique wave-generating machine that mimics the activity of real-life tsunamis with unprecedented realism has been used successfully in an Oxfordshire laboratory…
Tiny generators developed at the University of Michigan could produce enough electricity from random, ambient vibrations to power a wristwatch, pacemaker or wireless sensor…
In research that gives literal meaning to the term 'power suit,' University of California, Berkeley, engineers have created energy-scavenging nanofibres that could one day be woven…
