Here is another neat charger invention for you, a simple one that makes use of hot water to get some juices flowing for your prized device. The Bottle Charger was designed by some visionaries over at Nairobi, Kenya, something that features a plastic bottle.
To make it work, a cup of boiling water is poured into the 5-gallon plastic container which can reportedly charge mobile phones and devices in 15 to 30 minutes. The Bottle Charger uses a small Blackbeard Unidirectional Constant Turbine (B.U.C.T.) to generate energy along with the rise and fall of temperatures.
The Bottle Charger should be a neat charging alternative, especially if you are looking for one oustside the many solar-powered chargers out in the market. Though it is limited to mobile devices, the use of old materials and natural sources does make it an impressive charging device to consider.
