Cars kill people. Cars lose you time. They cause pollution of the environment. Building roads for cars, trucks and major vehicles costs money, planning time and involves infrastructure overhaul. Cars are cheaper and getting faster, you’ll agree. But can cars fly?
Yes, cars can fly. Prototypes have been tested and they are workable. Welcome the “Flying Roadster” by AeroMobil (the video). Version 3.0, according to official sources, will be available in 2017. Jacob Hall, who covered a South By South West (SXSW) pitch by AeroMobil for the Entrepreneur.com quotes AeroMobil co-founder and CEO Juraj Vaculik as saying: "We deeply believe we need a revolution in personal transportation.”
In another related development, which is no longer news because Apple, a rival technology company has publicly made its intention of going into electric cars known, Google has announced that its driverless cars will be available to the public come 2020.
Imagine cars that change colors on-demand, or bridges and buildings whose colors reflect the amount of strain or stress applied to them. We would all benefit from such innovation.
Last week, March 12, researchers at the University of California, (UCL), Berkeley, announced the creation of a thin semiconductor film of silicon, 120 nanometers thick, that when flexed or bent can reflect colors on a wide variety of the light spectrum; a color-changing sensor film.
Attempts at creating a color changing sensor is not new. Last year, in a research funded by the National Science Foundation, (NSF), researchers at the same University, but the Riverside campus, created a nanosphere-laced polymer that changes color under stress using gold nanoparticles. What differentiates the silicon film from other sensors is that the range of reflected light is much flexible and the material used was much more permeable to bending or flexing.

The idea behind the invention came from nowhere but nature. They conceived the idea of imitating butterflies and beetles who create iridescent displays of colors.
According to one of the researchers, "the next step is to make this larger-scale and there are facilities already that could do so," said Chang-Hasnain. "At that point, we hope to be able to find applications in entertainment, security, and monitoring."
Cars of tomorrow might respond like a chameleon to its environment, or change to colors reflecting the amount of pressure applied to the body, or in relation to the amount of stress or strain undergone during its lifetime. The possibilities are enormous.
