Rob ⚡️ Oh this is cool! How often do you find you need to charge yours?
In terms of other tech that could benefit from this, you could somewhat implement it into portable Bluetooth speakers - quite a lot of people use these on holiday and they will be outside, so it only makes sense to allow the sun to help with the charging and not worry about your favourite playlist cutting out 🎵
Have you thought about a toaster perhaps?
