The present “Solar Energy” science book hopefully opens a series of other first-hand texts in new technologies with practical impact and subsequent interest. They might include the ecological combustion of fossil fuels, space technology in the benefit of local and remote communities, new trends in the development of secure Internet Communications on an interplanetary scale, new breakthroughs in the propulsion technology and others.

As a proton-exchange membrane fuel cell (PEMFC) can be started instantly at ambient temperatures and can work with air as oxidant without carbon dioxide problems, it is so far the most viable fuel cell (FC) system that has the potential to replace internal combustion engines (ICEs) and batteries for transportation applications to power cars, buses, and personal electric vehicles (PEVs). This article focuses on the application of this technology for light traction vehicles, such as scooters, bicycles, forklifts, wheelchairs, and tour carts.
It is no secret that the average smartphone today has more
computing power than Nasa used when it landed an astronaut on
the moon in 1969. The trick has been to make that power available
at a price that the average person can afford. Technology Pioneer
Tobii Technology has gone a long way towards doing just that
with a system that uses an invisible beam of infrared light to track
eye movements. Patients paralysed from the neck down can use
Tobii’s equipment to steer a wheelchair, while victims of locked-
