Several large companies, like Google, Facebook, and Space X, are already working together on a project that will bring the Internet to everyone on the planet at speeds over 1 megabit per second.
Dr Povey's group is already up to 130 megabits a second (faster than some older Wi-Fi routers) over a distance of about two metres, using standard LEDs.
Researchers in China recently showed that, using a one-watt LED bulb, li-fi could connect four computers to the Internet at data transfer rates up to 150 megabits per second.
And while some have complained about Valve's choice of a wifi five chip instead of wifi six I saw 580 megabit per second download speeds from gigabit fiber over a powerful wifi router.
At a whopping 0.05 megabits per second, the average person could access a whole new world of information pixel by pixel, but that didn't stop people from enjoying the internet.
Each Voyager spacecraft has a 3.7 meter antenna for real-time transmission and an 8-track digital tape recorder capable of buffering 536 megabits for future transmission, enough to store 100 photographs.
Now let's continue exploring how a powerful beam can be continuously swept across the sky and then how we fill it with hundreds of megabits of data every second.
