Dieselesque petrol engines take to the road
A FLEET of Volkswagen Golfs (Rabbits to Americans) that get a staggering 94 miles per gallon (or, as Europeans say, 2.5 litres per 100km) are running around Berlin. Something like the Golf “Twin Drive” is what many of us will be driving within five years.
We probably won’t get the [...]

Invisibility Cloak And Ultra-powerful Microscopes: New Research Field Promises Radical Advances In Optical Technologies »

A new research field called transformation optics may usher in a host of radical advances including a cloak of invisibility and ultra-powerful microscopes and computers by harnessing nanotechnology and “metamaterials.”
The field, which applies mathematical principles similar to those in Einstein’s theory of general relativity, will be described in an article to be published Friday (Oct. [...]

Creating Wireless Network Using Visible Light »

Boston University’s College of Engineering is a partner launching a major program, under a National Science Foundation grant, to develop the next generation of wireless communications technology based on visible light instead of radio waves.
Researchers expect to piggyback data communications capabilities on low-power light emitting diodes, or LEDs, to create “Smart Lighting” that would be [...]

Smart Electricity Meter Developed »

The Power Electronics team from Swansea University’s School of Engineering has developed one of the world’s most advanced Smart Electricity Meters. And the team is now supplying nearly 1.5MWh per year of free ‘Green electricity’ to the University, helping to reduce its carbon footprint.
The team, based within the Electronic Systems Design Centre, implemented their prototype [...]
