  • A new light on saving energy

    Some 80,000 dynamic street lights have been installed in Europe over the past few years. Quite a modest number if you consider that there are some 91 million light points in Europe. The city of Oslo alone has 54,000 street lights. A dynamic street light is a system that tells you exactly how much energy each single luminary is using and when its lamp needs to be replaced. It adapts the light ...

  • Turn the lights - on?

    How many times have we heard that what people at work need to do is : 'Turn the lights off'.  Whenever I run courses for managers on Environmental Management Systems (EMSs), 90% say what they want to communicate with their workforce is to 'Get them to save energy - turn the lights off'. Yet what we should be doing is getting people to turn the lights on in their minds - there is much greater ...


  • Lethal light

    From radio signals to gamma waves, the electromagnetic spectrum offers considerable potential to prepare and preserve food products.

  • Hybrid powertrain for light aircraft

    In this paper, we evaluate the possibility of employing a hybrid powertrain to propel a light aircraft. The work suggests that the incorporation of a hybrid powertrain has little effect on fuel consumption for a light aircraft operating in a condition of straight and level cruise. However, there is a potential decrease in fuel consumption when a light aircraft operates either in climb or when ...
