Sony introduces portable hand-cranked USB charger

Cool, but I thought something like Solar with a Juice pack would have made more sense.

Полезная штуковина, +100

Some might find it silly, but this is a product made in a country where a major nuclear reactor is, in a nutshell, no longer in operation. Power outages aren’t nearly as common as they were right after the horrible earthquake and tsunami, but it definitely has left a lasting impression considering the Tokyo is relatively far from Fukushima, and yet Tokyo was drastically affected for months.
Sony doesn’t expect people to buy this in droves so consumers can start saving electricity by hand cranking their cellphone all day. That bit is for emergencies. However, there are already a number of emergency products (hand crank radios, mostly) on the market. This is why it also comes with a decent capacity battery.

It does. Are you illiterate? This is for when you don’t have any power sources, like during a blackout or natural disaster.

This is awesome technology. If we can attach such chargers to the various rotating things around us, we can generate whole lot of electricity. .

Good job Sony. It is really a great innovative breakthrough and will really help in case of a disaster or emergency.

The various rotating things around us will then use more energy; and some of the energy will go lost to warmth etc. So basicly it will cost us more then it will give us
