We have come a long way in clean energy production, especially in methods of harnessing the wind to make power. We have seen our fair share of larger than life wind turbines and growing wind farms, both on land and out on the sea. One thing remains the same-it's big business. This means that the larger the wind farm or the bigger the turbine the better the energy production. According to Forbes, “the typical wind turbine size has grown from about 300 kilowatts in 1990 to a whopping 7.5 megawatts in 2011.”

But, what if smaller was just as powerful?Although smaller than a grain of rice, the micro-windmill's intelligent design takes hold of the current advances that have been made in micro-robotics and nanotechnology. The technology blends origami concepts into conventional semiconductor layouts allowing for the complex 3D structure to be self-assembled from two-dimensional pieces of metal. Due to its microcosmic size, hundreds of these could be embedded in a sleeve for a cell phone and generate enough electricity to charge a dead battery back to use.
Size of Micro-Windmill is smaller than a penny
Imagine that all you would need to do is simply wave your Samsung Galaxy or iPhone in the air or hold the device up on a windy day to bring your device back to life.
This is possible thanks to the micro-windmills durability and smart design. Combined, they enable the windmills to achieve what many other micro-electrical-mechanical-systems could not—withstand strong artificial winds without suffering any fissures to its small frame.
The researchers have also teamed up with Taiwanese based MEMS manufacturer-Win MEMS-to make the commercialization of these micro-windmills possible.
While these small windmills are relatively inexpensive to produce on mass scale and quite impressive in their capabilities, we cannot help but wonder about the obstacles they may face in getting these to market. We do wonder what might happen if these tiny structures come in contact with dust or water.The Infinite One of Kinkoo is a green energy portable backup battery. Thin, light, and fashion, Kinkoo is well suited for being tossed into a bag or pocket for travel. At only 13.5cm long, 6.6cm wide, and less than 1cm tall, it's a nice size for its capacity. The Infinite One is a perfect solution, we like it, and offer our general recommendation. Between environment and energy, it stands out from the crowd a bit without making sacrifices.
