Contact lens technology could offer alternative to battery power storage

Research by UK organisations the University of Surrey and Augmented Optics, in collaboration with the University of Bristol, has developed technology which could revolutionise the capabilities of appliances that have previously relied on battery power to work. It could also revolutionise electric cars, allowing the possibility for them to recharge as quickly a regular non-electric car refuels with petrol, instead of the current process which takes approximately 6-8 hours.

Research by UK organisations the University of Surrey and Augmented Optics, in collaboration with the University of Bristol, has developed technology which could revolutionise the capabilities of appliances that have previously relied on battery power to work. It could also revolutionise electric cars, allowing the possibility for them to recharge as quickly a regular non-electric car refuels with petrol, instead of the current process which takes approximately 6-8 hours.

They believe the development by Augmented Optics could translate into very high energy density super-capacitors making it possible to recharge a mobile phone, laptop or other mobile devices in just a few seconds.

They say the technology, adapted from the principles used to make soft contact lenses, which was developed by Dr Donald Highgate of Augmented Optics, could have an impact across a number of industries, including transport, aerospace, energy generation and household applications such as mobile phones, flat screen electronic devices and biosensors.  Super-capacitors, an alternative power source to batteries, store energy using electrodes and electrolytes and both charge and deliver energy quickly, unlike conventional batteries which do so in a much slower, more sustained way. They have the ability to charge and discharge rapidly over very large numbers of cycles.  However, because of their poor energy density per kilogramme, approximately just one twentieth of existing battery technology, they have, until now, been unable to compete with conventional battery energy storage in many applications.

Super-capacitor buses are already being used in China, but have a very limited range; this technology could allow them to travel a lot further between recharges.  Instead of recharging every 2-3 stops this technology could mean they only need to recharge every 20-30 stops and that will only take a few seconds.

Elon Musk, of Tesla and SpaceX, has previously stated his belief that super-capacitors are likely to be the technology for future electric air transportation.

    Bluetooth and Wi-Fi offer new options for travel time measurements
    New trials show Bluetooth and Wi-Fi signals can be reliably used for measuring travel times and at a lower cost than an ANPR system, but which is the better proposition depends on many factors. Measuring travel times has traditionally relied automatic number plate (or licence plate) recognition (ANPR/ALPR) cameras capturing the progress of vehicles travelling along a pre-defined route. Such systems also have the benefit of being able to count passing traffic and have become a vital tool in dealing with c

    Rethink required to reduce road transport’s environmental impact
    Against a background of a renewed focus on limiting the rise in average temperatures, Colin Sowman looks at a project that is taking a holistic approach to the environmental impact and safety of road transport. At the COP21 meeting in Paris last December, almost 200 nations agreed to reduce greenhouse gas emissions in an effort to keep the rise in global temperatures to 2°C) compared with pre-industrial levels. The transportation sector is a major contributor to the production of CO2, one of the main green
