Power plants of the future may be designed to provide electricity solely for an individual housing estate, village, factory or college. That’s the prediction of University of Southampton engineer Dr Tom Markvart.
He claims large-scale systems of electricity generation used at present waste considerable amounts of energy by producing unwanted heat. It is also difficult to incorporate environmentally-friendly sources of energy such as wind farms and solar panels because of their intermittent and unpredictable outputs.
Dr Markvart, of the University’s School of Engineering Sciences (SES), is advocating the development of microgrids to provide a stable and reliable power supply from various energy sources. Small-scale generating equipment sited close to the eventual energy users could act as a stand-alone source of power, especially in remote areas, or be linked to the national grid. Energy storage devices would provide extra power at times of high demand. The proximity to customers would help boost energy efficiency to around 80 per cent compared to 35-40 per cent for a conventional generation system.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
