Harald presented his idea as a innovative response for the massive extension of the Internet that there will soon be in order to close the digital divide, and also to allow thousands of devices, such as cars, coffee makers or alarm clocks. to be connected to the internet through Li-Fi, instead of using Wi-Fi. This process is rather simple, Li-Fi uses light to transmit data to solar cells and panels which harvest the energy that then will be received by the different devices. Therefore, we will be able to be connected to the internet even in those places where the infrastructure does not permit it, such as roads and countrysides.
I found this talk really interesting because I believe that technology may be the solution for problems such as pollution and energy consumption. Furthermore, it is a fact that the Internet makes our lives pretty much easier in every aspect. Therefore, by replacing batteries with solar panels to be used for Li-Fi not only will we improve environmental issues but also, we will be connected every time, everywhere.
