A team has developed a device that can charge your mobile phone using the heat produced by a burning candle.
You don't need to wait on your electricity team to solve the problem. You can make use of a small generator Charger Candle shaped lighter that uses thermal energy from candles to generate electricity.
Each wick would provide you up to 6 hours of energy to recharge. Just add water, light the candle, let it boil a little and finally connect the USB cable. Even with disinfected water you can prepare a good cup of tea. This Candle Charger is seeking funding on Kickstarter and you can share yours for $ 75. The product will be available on the market in December 2015.
