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. 🙂
I don’t usually wear sunglasses, but I’d definitely wear these:
The frames are standard, but the lenses collect solar energy which is transferred to the electronic gadgetry hidden in the arms. That gadgetry could be enough to power small wearables such as hearing aids. For me though, the most exciting part is this:
‘Organic solar cells were chosen instead of more traditional silicon cells because they’re transparent, flexible, lightweight, and can be manufactured in a variety of shapes and colors. Each solar cell lens weighs about six grams, is 1.6 mm thick, and was made to fit into a set of commercially-produced sunglass frames.’
The blue highlights are mine, and they’re exciting because the same cells could also, in time, be used on windows. Imagine how much energy could be harvested if windows became solar panels as well as roofs? And think of all those huge skyscrapers – perfect realestate for solar farms. 🙂

This is a must-read article from Quartz [another one of those tech channels I love] about what the movie ‘Back to the Future 2’ got right, and wrong. I was amazed at how much the movie actually got right, but see for yourselves:
I was also amazed at how much futuristic stuff my brain now takes for granted. Holograms are an obvious example, but the view ‘window’ I wrote into Innerscape is another. -grin- Wish I’d thought of that!
