We are experiencing a strong transition in the way of life for people all over the world, accelerated by the pandemic that is plaguing us at the time of writing this article. There will be a disruption, in which our old customs will be totally forgotten, and we will move on to a new era in which customs will be different. In this article, we focus on what, in our view, this will mean for science and technology.

With advances in technology, especially those involving quantum physics, we are increasingly realizing that a time travel may be possible in the future. Maybe it is not the way the well-known film "Back to the Future" preaches, as we're just crawling into the understanding of its phenomena. But there is something behind it. In this article we make some interesting considerations on the subject.

In my book Electronic Projects from The Next Dimension published by Newnes in 2001, I discuss in a practical article about a panic generator capable of simulating a sonic attack or even carrying it forward using what is called the Brontophonic Sound. I did not find many references on the subject, since even at the time I wrote it was a novelty, so I will try to comment a little about this strange form of sound in this article.

The plasma speaker or ionophone is not a new idea. The “singing arc” was invented by William Duddell in 1900 and then the ionophone by Sigmund Klein. We have not yet reached a sufficiently efficient version to be marketed, but curious readers can conduct experiments and even demonstrations at events with the ideas we give in this article.

The same way the traditional racing of mechanical vehicles with internal combustion engines worked as a laboratory for the development of all the technologies which have been part of the traditional cars during all the last years, Formula E with all its electric vehicles emerges as a new laboratory for the vehicles that should be part of our lives in the coming years: the electric car. In this article, we comment a little on how formula E races should contribute to the development of new automotive technologies.
