Engineers Envision Cheaper Algae Oil Production

Compared to soybeans that produce 50 gallons of oil an acre a year, some algae can average 6,000 gallons - but it's not cheap to produce. Two Kansas State University engineers are assessing systematic production methods that could lower the costs of algae oil production. They plan to grow algae in the ocean on very large, supporting platforms.

Harvesting Energy from Regular, Day-to-Day Motions

Duke University engineers have developed a novel approach that they believe can more efficiently harvest electricity from the motions of everyday life. Although motion is an abundant source of energy, only limited success has been achieved because the devices used only perform well over a narrow band of frequencies.

Silver Nanoparticles Give Polymer Solar Cells A Boost

Researchers at Ohio State University, led by professor Paul Berger, are experimenting with polymer semiconductors that absorb the sun’s energy and generate electricity - with the goal of lighter, cheaper, and more-flexible solar cells. The team has discovered that adding tiny bits of silver to the plastic boosts the material's electrical current generation.
