Why Light Energy works, even when there is no light

We got some questions on how Light Energy works. One of those questions is how we've managed our magic to make the promise of never having to use batteries again. It isn't a bad question, because if you look at solar power, that only works when you see some sun, right? Especially if you want some efficiency out of them.

In our team of engineers there is an actual rocket scientist. Daniël Bakker has a degree in Aerospace Engineering. So if someone is qualified to shine his light (pun intended) on this matter, he is your guy. So the question is how do we do it?

 
You can compare it to your computer’s RAM memory and the old fashioned hard disks

Daniël from now on: Well - actually it's the simplicity combined with advanced engineering and technology that does the trick. You start by using solely super low energy hardware like Bluetooth LE, LoRa as a basis. The Light Energy module is completely re-engineered with it's power management system to have ludicrous efficiency in low light conditions. You only need 4 hours of light at 200 lux (which is so little) to power the complete device for 24 hours.

 

Amount of lux you need

 

This is because we use a technology that is renown as a 'super capacitor' - which sounds really spectacular if you don't know what it is.

Where a battery charges slow, wear out after some charges - but is capable of storing large quantities of energy - the super capacitor is not. Where the super capacitor shines (again, pun intended) is at storing small amounts of energy super fast with little to no wear. You can use it for tens of thousands of cycles before it wears out. You can compare it to your RAM memory and the old fashioned hard disks in a certain way.

And it's just about a centimeter wide, so it doesn't take large amounts of space of your precious tech real estate. To sum up: we charge extremely efficient by harvesting the smallest amounts of light into energy and store it on something that isn't really a battery, but isn't a regular capacitor as well. It's actually best of both worlds.

So that's why we can say: batteries, not anymore.
