Cell phones that can convert the sound of your voice into energy to run the phone may be coming ... Research at Texas A&M by Tahir Cagin is getting closer to self powered devices like cell phones "... converts sound waves ... into the energy it needs to keep running. ...Utilizing ..."piezoelectrics," ...  a certain type of piezoelectric material can covert energy at a 100 percent increase when manufactured at a very small size – in this case, around 21 nanometers in thickness.

" ...  piezoelectrics are materials (usually crystals or ceramics) that generate voltage when a form of mechanical stress is applied. "

... "An untreated silicon solar cell only absorbs 67.4 percent of sunlight shone upon it - meaning that nearly one-third of that sunlight is reflected away and thus unharvestable. From an economic and efficiency perspective, this unharvested light is wasted potential and a major barrier hampering the proliferation and widespread adoption of solar power. After a silicon surface was treated with Lin’s new nanoengineered reflective coating, however, the material absorbed 96.21 percent of sunlight shone upon it - meaning that only 3.79 percent of the sunlight was reflected and unharvested. " ...

 Solar panels are becoming more common; almost mainstream.

  What is now needed is a way to boost the efficiency or redue the manufacturing cost.

"Nanosolar is a global leader in solar power innovation. ...  setting the standard for affordable green power with solar cell technology of distinctly superior cost efficiency, versatility, and availability."

"Leveraging ... nanostructured materials, we have developed a critical mass of engineering advances that profoundly change the cost efficiency and production scalability of solar electricity cells and panels."
