BP has been around since the early 20th century. As you may have heard there is a great disaster in the Gulf of Mexico. There is a oil spill that pours more than 200,000 gallons per day. Eleven people died in the explosion of the oil.
Dr. Ville Kaajakari, assistant professor of electrical engineering at Lousisana Tech University has developed a technology that harvests power from a small generator embedded in the sole of a shoe. The shoe efficiently converts a piezoelectric charge used to charge useable batteries or directly power electronics. They could be used to power portable devices without the use of wasteful batteries. The breakthrough uses low cost polymer transducers that has metalized surfaces for electrical contact. Unlike conventional ceramic transducers the polymer based generator is soft and robust matching properties of regular shoe fillings. Therefore the transducer can replace the heel shock absorber with no loss in user experience. The new shoe will be on sale in 1-2 years for about 11$ per heel insert.
Remember the article about the great ocean garbage patch? I have some good news for you if you were concerned. There is a new form of plastic that is biodegradable. The plastics that are normally used are petrolium based but this new plastic is manufactured from biomaterial.
But it is not that easy. For instance you cannot just bury it in any landfill. You must put it in compost areas or they will not decompose properly.
Secondly, they release a small amount of Co2 when they biodegrade, I guess that this is a small price to pay for all the good that it will bring .
The Sun Chip bags and the new PaperMate pens have this ability along with some plastic dinnerware.
