I know that most of you won’t be interested in the technical side of this article: https://www.physics-astronomy.org/2020/04/mini-generator-cheaply-converts-heat.html but it could have really important implications for how we use technology in the future.
At the moment, wearable technology is limited by the need to power the device[s] :
a) without bulky batteries, and
b) without those batteries quickly going flat
We could wear little solar panel hats; they could charge the batteries as we walk around. But only outside, and only when there’s some sunshine. Plus there’s the added problem of fashion. Hats simply aren’t ‘in’ at the moment.
Or…we could use the heat of our own bodies to generate power. Mammals maintain a constant body temperature so we could have a constant source of power to run our wearable devices – no need for batteries at all.
Using body heat to generate power isn’t a new idea, but the research described in the article offers a new, more efficient way of doing so. If the researchers can make it work at a cost efficient price, we could be wearing our computers and communications devices within twenty years. Or less.
Let’s just hope that fashion and function go hand in hand. 🙂
