Researchers have devised a method that could power electronic devices from any source of movement

One of the biggest issues with keeping batteries in a myriad of devices charged is how to generate the electricity needed to charge them. Work around the world is being done on new methods of generating electricity from wind power to harnessing the power of ocean waves.

A group of researchers from the Georgia Institute of Technology has announced a new breakthrough that could one day provide power to cell phones and other electronics devices by generating electricity from blood flow in the body.

The researchers have devised a method that allows the generation of energy by converting low-frequency vibrations from body movement, heartbeat, blood flow, and the wind into electricity. The discovery uses zinc oxide nanowires that generate electricity when subjected to mechanical stress.

The nanowires are very small at about 1/5,000th of the diameter of a human hair and about 1/25th of the length of a human hair. According to researcher Zhong Lin Wang from the Georgia Institute of Technology, the nanowires can be grown on materials like metals, ceramics, polymers, and clothing.

Wang told MSNBC, "His research will have a major impact on defense technology, environmental monitoring, biomedical sciences and even personal electronics."

Wang sees the technology being integrated into military clothing where electricity can be generated and used to power devices in the field such as radios and night vision goggles. The nanowires could also be used to power biosensors implanted under the skin.

Wang said, "Quite simply, this technology can be used to generate energy under any circumstances as long as there is movement." Wang and his team's research was funded by DARPA.

A group of students from MIT also recently announced the development of a shock absorber for vehicles that uses the up and down motion when driving to generate electricity. Shock absorbers of this type could be used in future hybrid or electric vehicles to increase the electric powered run time.

I'm with you. The existential baloney they came up with might have pleased the critics, and it was actually pretty highbrow sci-fi, but it wasn't all that entertaining.

I think they changed the storyline so they could cancel their expensive render-time contracts and stop having space battles. The special effects went out the window after the Pegasus went out in a blaze of glory, and all we had left was angels and prophecies. Bah!

OK, it was different. They should have at least had some more hand-to-hand fighting with Centurions, etc. rather than the little flashes we got at the end of the series. Even the grand finale was disappointing. Actually, my wife liked the series better than I did by the end - and that is just plain wrong, for sci-fi.
