Researchers in South African have developed a new cleaning system for solar panels that uses a colour-sensing light-to-frequency converter to detect dirt. It can reportedly remove about 95% of the dust from a PV panel in less than a minute, at a lower cost than other systems.

It’s common to hear engineers and computer boffins say that digital computers are based on 0s and 1s, but what does this actually mean? On the one hand, this is relatively simple; I mean, 0 and 1, how hard can it be? On the other hand, there are so many layers to this metaphorical onion…
