Don’t Sweat the Small Stuff – #WATWB

Image that says we are the world

Welcome back to the monthly bloghop – We Are The World Blogfest. It is a time to share snippets of good news happening around the world in an effort to diminish the impact of negative news.


WATWB is co-hosted this month by Mary J. Giese and Belinda Witzenhausen.


There are many electronic devices these days and more and more wearable devices. The impact of the batteries required to charge those devices is another one of those dirty little secrets many people are either ignorant of or choose to ignore in favor of the convenience of the technology.

Both the manufacture and the disposal of these batteries are neither sustainable nor are they good for the environment.

There is good news on the horizon, however. Engineers from the Nanyang Technological University in Singapore have developed a tiny bandage thin battery that is charged off of ‘sweat’. This battery can discharge 20 hours of electricity from 2 ml of perspiration.

During testing, a volunteer was able to generate a voltage of 4.2 V and an output power of 3.9 mW. That’s impressive. Imagine a battery powered by perspiration rather than one damaged by perspiration.

Read the story in its entirety here.

  1. Wow, that’s ingenious. They could probably charge up one of those batteries for days with a hot and sweaty yoga class. It will be good to have these batteries on the market – anything we can do to save the climate and the planet itself will help. Thanks for this WATWB story!

    1. Thanks for reading, Mary. I have been distressed by all the dirty little secrets behind ‘clean energy’ and the batteries that power it. This is a long way from helping with cars and larger energy requirements but it is a start.

  2. Wow, this is a wonderful idea. With most of our daily gadgets I cringe at the thought of what happens when our devices get discarded. Sadly we’ve become a society of “newer, better, faster when it comes to our electronics and just to access what we need we are forced to upgrade. I love this idea and as a “menopausal” woman with my hotflashes…I think I could “power the world” ( insert devious laugh) lol. Great post! Thanks so much for sharing this month and for being a part of #WATWB! Have a wonderful weekend!

  3. Wow, I could have powered half our house working outside during the heatwaves we’ve had this summer 😉

    Seriously, this is great news. Even though we recycle them, we go through a lot of batteries around here.

  4. Thanks Maggie, this is great technology. And you’re right re the dirty secrets about their origin. We also recycle all batteries – hopefully they can be put to good use. I gather that solar is now useful for re-charging …

    1. We had a store that once took home batteries for recycling. Now they tell us to ‘just put them in the trash’ which sadly means they end up in the landfill.

  5. In hot or sunny countries, small solar cells should be put to better use. Even in Beetley, which is gloomy for most of the year, the solar-powered light outside the house never fails to charge and give out a light when needed at night. As for the huge batteries needed to power electric vehicles, they are an environmental catastrophe waiting to happen to some future generation. Then when the cobalt runs out, maybe the tech guys are going to have to re-think the whole question of battery-powered anything.
    Best wishes, Pete.

    1. People hear ‘electric car’ or ‘clean energy’ which simply means perhaps a little less fossil fuels burned, but the environmental impact is simply shifted elsewhere. Those poor people who work in the lithium, cobalt and nickel mines (often slave or child labor) pay the first price, but globally we will all suffer. Even solar power requires these batteries and the disposal as well as the generation of them have huge environmental consequences.
