What kind of product Kraftwerk is like is understood by seeing the following movie and so on.


Kraftwerk fits in the palm of a man. A fuel cell system is housed in a small body, and it is a device that can generate electricity simply by injecting a gas for a lighter which is generally commercially available. "Kraftwerk" is a German word meaning "power plant".


Inside is a tank for gas and a fuel cell that produces electricity by reacting gas and air. Of course, lithium-ion batteries etc. are not built in, it is possible to supply 5 V · 10 W maximum power from the USB terminal installed in the main unit.


The scene actually using Kraftwerk is here. If you plug in a USB cable to use a common mobile battery ......


Charging of the iPhone has started. It does not have a power switch etc, and "plug-in power" method which operates only by inserting the cable is taken.


However, when the fuel gas runs out, power generation stops. In such a case it is OK if gas is injected from a commercially available lighter gas cylinder. In Japan it is now possible to use types using butane gas which are sold at convenience stores and home centers.


Put the cylinder in the gas inlet of the main body and inject it with "Pushu" OK. Gas refilling was completed in just 3 seconds.


Depending on usage, it is possible to supply about 11 times of iPhone with one refill gas. The body size is 10 × 7.5 × 2.9 cm, the weight is about 200 grams. Since it has cleared FAA's safety certificate, it can be brought into the cabin of an aircraft and used.


Detailed specifications are as follows. The output voltage is 5 V, and the supply power is maximum 10 W / continuous 2 W. A general mobile battery using a lithium ion battery seems to be said to be said to be somewhat inferior in continuous supply power, since it is almost the type that can output 5-10 W output.


This Kraftwerk is a cloud funding siteKickstarterWe are looking for investment in. About 500,000 dollars (about 60 million yen) of the target amount, approximately 620,000 dollars (about 73 million yen) contributions are collected at the time of article creation.

Kraftwerk is planning a price of 149 dollars (about 18,000 yen) at the time of marketing in general, but benefits such as early discount are of course set in Kickstarter's campaign. The "Early Bird" plan that can get the initial lot as early as possible has already been framed, but you can get one Kraftwerk with a contribution of 99 dollars (about 12,000 yen).


With a contribution of 139 dollars (about 16,500 yen), it is also possible to get a set of 12 gas cartridges for replacement in addition to 1 Kraftwerk.


In the case of the investment amount of 249 dollars (about 30,000 yen), you can get 3 colors of Kraftwerk in all colors.


The 1000 dollar (about 120,000 yen) plan is a little funny plan so that 12 Kraftwerk can be awarded to non-governmental organizations which add their own Kraftwerk to disaster relief.


Both plans are included in the price for shipping costs. The deadline of investment is Japan time at 8:27 on March 6, 2015 (Friday), and the shipping time is scheduled around the next February 2016.
