How do you build the three gorges hydropower station to do? It was wide of the mark to say that, lasting since the river often floods in the upper reaches of the Yangtze River, in order to save all the people. Leaders would take the thigh head and chest, encountering all sorts of thinking and poor exhausted taking into account to come up with a way, dam section of flood, then came the three gorges hydropower station. Black out into today’s topic: small hydro power equipment Blue Freedom. The device from a Germany company, to convert the kinetic energy of moving water into electricity and then for use by mobile devices.
Before the Blue Freedom, also uses hydroelectric power for portable devices, such as water flow generator HydroBee. However, Blue Freedom claims that the device is the world’s smallest. Weight approximately 57g lighter than HydroBee a lot, and is very portable. Therefore, when traveling, you can put it in the backpack. Entire product size is 20 cm long *5.5 thickness, which includes small turbines with a diameter of 12 cm, a generator and a 5W 5000mAh lithium-ion batteries.
At the time of use, turbine (figure on a blue piece) thrown into the flow of the water, Blue Freedom mother to charge through a data cable connection. Unfortunately, there is no USB-C interface. You can also let it recharge itself, after a full charge it again it does not matter, after all, have a 5000mAh lithium-ion batteries. Precautions for use, Blue Freedom, does not require a particular position, as long as the water is flowing on the line. Water temperature is maintained at 5~40du, below 5-kilometer.

See here, some people may feel that Blue Freedom is a very interesting product, Yes, according to the plot, next to find fault.
First: when engaged in outdoor activities or travel, encountered than exposure to sunlight to flowing water. And solar energy can move while charging. According to United States and Canada data of hydro-electric power, hydro-electric power efficiency is better than solar, 90% water could be visualized as kinetic energy is converted into electrical energy, which is as long as the conversion rate of 15%.
Second: how water velocity is called “flowing waters”? What is the relationship between speed and power? Blue Freedom said the device in the flow velocity is 1.2 m/sec (1.2 m/s) case, in 3-4 hours, 5000mAh lithium-ion battery is fully charged. In other words, 1.2 m/sec under the water, take 1-2 hours with one iPhone 6. What is this concept? For example, Powertraveller Solarmonkey solar charger Adventurer take 8-10 hours to the company full of 2500mAh batteries.
Third: travel sites is the desert, cities, and where there is no river, even if it’s portable is a useless thing. Go to these places, why did you take it? This is not the problem. It was supposed to solve the problem is to those found in the River, electricity design of outdoor activities.
At present, the Blue Freedom is just a prototype, raised $ 100,000 through Kickstarter platform for mass production. If all goes well, the final product will be listed in October this year, now raise prices to $ 219. If Blue Freedom promised by the charge efficiency is true, than solar power, this is a good choice, but also third party, for this burn. If not, will only lead to more disappointment.

Over the previous “no design is good design” phone 4 the emphasis on design and process is clear, we can see millet’s breakthrough. Thankfully the screen, colors appear very pleasing eyes, MIUI V5 playability comparable to the system. Catch is, the hardware configuration is not more “enthusiast”, some lovely, heating controls need to be strengthened.
