Catch that energy
The designer behind the BioLite CampStove was obviously determined to get the most out of a campfirel.
Biolite's camp stove converts excess heat into electricity, which can be used to power up a USB, an LED light or charge a mobile phone.
And while it's not the traditional open fire to toast marshmellows by, Biolite says it is a much safer option.
Take a look and see if you have any ideas you could develop from this technology.

We asked Australian students to make a video or convince us in writing about their BIG ideas for a sustainable energy future.
Check out the fantastic videos we received, all about sustainable energy solutions!
