Purple Bacteria and Photovoltaics

Purple bacteria are single celled microscopic organisms that were among the first life forms on Earth. The tiny organisms live in aquatic environments and use sunlight as their source of energy. Neil Johnson, a physicist at the University of Miami, thinks its cellular arrangement could be adapted for use in solar panels.

Bionic Coating for Fuel-Efficient Ships

The water fern salvinia molesta is extremely hydrophobic, surrounding itself by a flimsy skirt of air that prevents the plant from coming into contact with liquid. This inconspicuous plant could allow ships to have a 10 percent decrease in fuel consumption.

Innovative Waste Heat Recovery Systems and Improvements with Advanced Turbomachinery

The increasing cost of fuel and U.S. dependency on foreign fuel supplies has renewed interest in conserving energy and in generating electric power using otherwise wasted heat energy from prime mover processes. Such power generation systems are typically based on the thermodynamic Rankine cycle or the reverse Rankine cycles (i.e., a vapor compression, a.k.a. heat pumping). These systems can use water or organic-based (i.e., refrigerant-type) working fluids for Organic Rankine Cycle (ORC) power generation.
