Fuel cell battery charger by Toshiba
This is the first fuel cell battery charger on sale in the world. It is called Toshiba Dynario and until now it is only available in Japan. It works with concentrated methanol that Toshiba sells in little bottles/batteries. Dynario uses methanol and the oxygen it obtains from the air to produce, through a chemical reaction, DC electric current (5V-400mA). It can be connected to any USB device and it looks like with only one little methanol bottle you can recharge you cellphone several times. The product has been released only to test the market and is quite expensive, it costs 30,000 yen (222 euro, 332 dollars), but if it is successful there will be soon more fuel cell battery chargers on sale.
