Small is beautiful – scientist proposes new efficient and eco-friendly power plants

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 inter

Food devours energy

Over the past thirty years, the European food industry has failed to make significant improvements in energy efficiency, says Dutch-sponsored researcher Andrea Ramírez. Her conclusion is based on an analysis of energy consumption, energy efficiency and developments in the food supply chain in 13 European countries.

Andrea Ramírez investigated the energy management of the European food sector. She found out that while production growth has increased the energy requirements of the sector b

A new structural view of organic electronic devices

Although still in the qualifying rounds, U.S. researchers are helping manufacturers win the race to develop low-cost ways to commercialize a multitude of products based on inexpensive organic electronic materials–from large solar-power arrays to electronic newspapers that can be bent and folded.

In the on-line issue of Advanced Materials,* researchers from the National Institute of Standards and Technology (NIST) and the University of California at Berkeley report success in usin

Solutions to abrasion and erosion in wind generator vanes

Wind generator vanes can suffer degradation by erosion, particularly at their outer edge, produced by particles (dust, sand, etc.) which are present suspended in the air. Because of this, the ever increasing presence of wind parks in zones of extreme climate make it puts an onus on optimising the protection coating material, with the aim of guaranteeing good yields, even in the most extreme conditions.

The main parameters that affect this phenomenon are, on the one hand, gel-coat character

Shoe leather as a renewable resource: Penn biologists invent power-generating backpack

If you already have a little spring in your step, a team of biologists at the University of Pennsylvania would like to them to good use by adding a few more springs in the form of a power-generating backpack. Details of their prototype “Suspended-load Backpack” were announced today in the journal Science. The device converts mechanical energy from walking into electricity – up to 7.4 Watts – more than enough energy to power a number of portable electronic devices at once.

“As efficient

Making society independent of fossil fuels – Danish researchers reveal new technology

Scientists at the Technical University of Denmark have invented a technology which may be an important step towards the hydrogen economy: a hydrogen tablet that effectively stores hydrogen in an inexpensive and safe material.

With the new hydrogen tablet, it becomes much simpler to use the environmentally-friendly energy of hydrogen. Hydrogen is a non-polluting fuel, but since it is a light gas it occupies too much volume, and it is flammable. Consequently, effective and safe stor
