Burn a few sprigs or pellets in this device and a small 4cm diameter fan will send the heat produced through 51 nozzles to amplify the fire.
A small thermoelectric generator converts heat into electricity by sending 3 watts to a USB port that you can use to charge your mobile phone at half the speed of a home socket (not bad).
Excess energy is stored in a 2600mAh battery ready for use.
