A trip to the supermarket provided a reminder that without physics, chemistry, and mathematics none of our modern tech, internet, and online services would exist. Hardly a revelation, but what triggered this heightened awareness? Well, just the simple act of taking a small bag of spent disposable batteries to a recycling bin in the supermarket’s checkout area. The bin was full to overflowing with used disposable batteries from toys, clocks, TV remotes, cordless computer keyboards, wireless mice, and a myriad of other sources that use replaceable batteries as a power source. The act of depositing his spent batteries reminded the Badger that each one is actually a little capsule of physics, chemistry, and mathematics, and that our digital world depends on these subjects and batteries of one form or another.
On returning home, the Badger reflected on the science, materials, manufacturing, and recycling of these disposable batteries and whether they’ll ultimately be made redundant by newer power source innovations in the decades ahead. After all, the Titanium Citizen Eco-Drive watch on the Badger’s wrist uses solar and artificial light for power rather than replaceable batteries. It’s a technology that dates back to the mid-1970s, so it’s not new. Furthermore, the 1980s pocket calculator sitting on the Badger’s desk is also solar powered with no replaceable batteries. It’s a memento from a major 1980’s software development project and it works just as well today as it did back then! The Badger thus found himself wondering why power derived from light sources hasn’t rendered the disposable battery redundant in the last 40 years. Well, to make a functionally reliable, manufacturable, commercially viable product that has physics, chemistry, and mathematics at its core takes years of research to come to fruition. The good news is that it looks like lengthy research is bearing fruit and we may soon see a revolution that makes natural and artificial light the power source for a wide range of our devices, see here and here.
We should not be surprised that the coming years are likely to see a significant change in how our in-home devices, smart tech, and personal computing devices are powered. The use of replaceable batteries looks destined to decline. There’ll ultimately be no more charging cables, and no more trips to the supermarket to recycle spent batteries! Things, of course, are never that clear cut, but if light photons hitting panels on a home’s roof can generate electricity for household use, then it’s inevitably just a matter of time before light will power our gadgets and render disposable batteries redundant.
Fundamentally, power sources – and everything else in our modern digital world – are determined by physics, chemistry, mathematics and years of research. We should never shy away from being educated in these subjects because they – and light – are the seeds that will determine whatever we want the digital world of the future to be…
