It starts with a rapid rise on the back of hype and investment, followed by a collapse into the ‘Trough of Disillusionment’. The climb out on the ‘Slope of Enlightenment’ leads to 2G and 3G designs, the ‘Plateau of Productivity’ and a stable global business. This happened with the PC and the smartphone, and now it’s happening with electric vehicles (EV). The ups and downs of EV sales around the world, along with the challenges of charging infrastructure, are highly publicised, but miss the point. Engineers were addressing these issues four to five years ago. Now they’re working on tech for five years’ time, from battery pack sealing (page 34) and coil winding (page 44) to thermal runaway tech (page 64), and new materials and techniques (page 6). The drive to boost the energy density of battery packs (page 58) is not only reducing their size and weight, but it’s also a key factor in electric aircraft. Following years of engineering, a number of eVTOL air taxis and short-range passenger aircraft are entering the last stages of airworthiness certification, and being tested in commercial settings.
