You may not know this, but Fuel Cells are some of the cleanest and the most efficient generators of energy. Toshiba has recently release a Dynario portable fuel cell power generator. It weighs just 280 grams, measures only 15cm wide x 2.1cm deep x 7.45cm high and can produce enough power in 20 seconds to charge two mobile phones. The power is stored in in-built lithium ion batteries and can be transferred via a USB cable to your mobile phone or digital media player when needed. This is a perfect book bag accessory.
Dynario has a dedicated 50 ml cartridge for refueling. A single cartridge can be used to charge approximately three times. Fuel cells offer a more dependable and reliable charging option compared to other forms of energy like solar chargers or micro wind turbines. The great part about fuel cells as that the only emission that it produces is water.
Unfortunately there is a drawback of Dynario. The cost may be a bit much for some, which at around US$275 for the fuel cell generator and $30 for 50ml cartridge of methanol. I wonder if the cartridge can be refilled with methanol without purchasing more chargers? However, if you are one of those people who would like to have a very reliable source of energy for an emergency situation, this may be for you.
Another unfortunate part is that so far Dynario is only available for sale in Japan, but that may change hopefully in the near future.
