Run batteries

Run batteries

When running generate electricity

For many runners is an MP3 player now for the same equipment as the trainers. only that long distances often the batteries are left behind. So now inventors develop batteries that are running to recharge.

Joggers may soon be running their electrical charge. 

. The supply of mobile phones, PDAs and MP3 players with energy is a huge problem. What use the many great features that allow manufacturers to equip their devices if they consume as much electricity, batteries that in a short time are empty and the actual function you can not use? Experts are confident that the inventor of the power supply on a viable solution, will earn a gold nose.

"These technologies have great market potential," is Hinte Ralph Mann, an expert on IT and innovation markets in the industry association Bitkom, convinced. First promising solutions already exist - even if not all technical problems for daily use are resolved, "said Hintermann.

There are idiosyncratic innovations, but only for truly mobile people are capable of - for less sedentary. The U.S. startup M2E Power, for example, wants a battery on the market, exacerbated by moving charges. "Who him for six hours in your pocket or backpack around with them, is enough energy for one hour to produce mobile phone", the developers promise. However, the first solution in the form of a charger with extra battery on the market - until a year later to follow self-rechargeable batteries in the mobile phone to stay.

The operating principle is simple: It is based on electromagnetic induction, in the smallest movements of a load between the magnet and coil produce. According to M2E Power CEO David Rowe cellphone manufacturers show great interest in the technology.

One promising way to more powerful battery is also the piezo technology.Researchers at Texas A & M University, with extremely thin lead zirconate titanate a piezo electric material, which precisely at a thickness of 21 nanometers, the energy yield doubled. This could be the battery life significantly improved.

And not only that: Again movement ensures that electricity is produced. The ultra-thin material itself by changing the pressure and sound waves resulting kinetic energy into electricity in order. According to Tahir Cagin developer of the Texas A & M University could, therefore, even a call for new electricity. When the idea to the market could, however, he still can not say.

Even the heat from heated silicon nanowires could lead to the generation of mobile devices are used. Was already sufficient for the body heat or waste heat from processors, researchers from Lawrence Berkeley Laboratory and the University of California at Berkeley. The trick is in the physical principle of thermo electricity: When a thermoplastic material with electrical properties on the one side is heated, it begins in the electrons from the hot to cold side to walk - and it is flowing electricity.

This effect can also be the smallest area with a fine mesh of silicon wires reach.Surprising thing is that he, even without a metal can be achieved. In this constellation is similar to the silicon powerful as the best existing thermoelectric material, "says the head of the research teams, Peidong Yang. The development is, however, also at a very early stage.

Considerably more - but also bizarre - is the solution of the Japanese operator NTT Docomo, which has developed a shoe, which is also kinetic energy converts into electricity. The Techno slippers with its wires and boards still looks like fresh from the lab arisen. Its sole is filled with water, which at every step by a small turbine is pressed, which drives a generator.

This small stream provides much power 1.2 watts, allowing for comfortable walking and an MP3 player with power could be. Currently, the developer of NTT busy, the power flow from foot to head as far as possible to accomplish without cable and the power to three watts to increase, which for the mobile operation would suffice. Moreover, the shoe, as  he planned in 2010 on the market, are still chic. A Manolo it is never can be, but after a handicraft work of physics students, it may not even look.
