Battery technology hasn’t kept pace with advancements in portable electronics, but the race is on to fix this. One revolutionary concept being pursued by a team of researchers in New Zealand involves creating “wearable energy harvesters” capable of converting movement from humans or found in nature into battery power. A class of variable capacitor generators known as “dielectric elastomer generators” (DEGs) shows great potential for wearable energy harvesting. In fact, researchers at the Auckland...

New Technology Produces Cheaper, More Efficient Solar Cells

The sun provides more than enough energy for all our needs, if only we could harness it cheaply and efficiently. Solar energy could provide a clean alternative to fossil fuels, but the high cost of solar cells has been a major barrier to their widespread use. Stanford researchers have found that adding a single layer of organic molecules to a solar cell can increase its efficiency three-fold and could lead to cheaper, more efficient...
