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.

Its a good show, but the back story makes very little sense to me. I mean...why did the Cylons wait 40 years to attack? Why even come back? Why do they care? They have a planet of their own, leave us alone!

That's how Cylons roll. Never forgive never forget. It's in their memory banks. 40 years was to make sure our gaurd was down.

You're confused by the idea that the Cylons attacked on the very day that the last military ship capable of fighting them was schedule to be decommisioned? If you live forever, what's a 40 year wait to garauntee your revenge?

awww you guys are slipping, you need to watch the new season's episodes. They are all already mostly aired. I'm not going to tell you what happens and ruin it for everybody, BUT suffice it to say that many of the questions you posed will be answered...

Where do you live? Here in America all the episodes have aired already. Someone already mentioned a spoiler in this thread too. I think this is still a valid debate regardless of the ending. Seems to me it's all about a thing called revenge.

one thing they missed though is that zoroaster came way before greek religion. Then again, ahuramazda could be the cylon one god.

Wrong. There were many newer and active Battlestars more capable than Galactica, but they were all wiped out in the attack except Pegasus.

No, you're wrong.

Against the Cylons, "more capable" = "not networked". Galactica was the only remaining non-networked battlestar in the fleet, because Adama and Tigh wouldn't give up that particular discipline. The newer, active Battlestars were in fact less capable against a Cylon threat, and were comprised and destroyed almost immediately as a result.
