Researchers Turn Solar Energy into Electrical Power Using Photo-Bioelectrochemical Cells

A new paradigm for the development of photo-bioelectrochemical cells has been reported by researchers from The Hebrew University of Jerusalem, in Israel, and the University of Bochum, in Germany. The design of photo-bioelectrochemical cells based on native photosynthetic reaction is attracting substantial recent interest as a means for the conversion of solar light energy into electrical power.

New Solar Energy Storage Technique Could Boost Solar Cell Usage

Researchers at Missouri University of Science and Technology have developed a relatively inexpensive and simple way to split water into hydrogen and oxygen through a new electrodeposition method. The method produces highly efficient solar cells that can gather solar energy for use as fuel. The research, sponsored by the U.S. Department of Energy, could lead to a sizable increase in the amount of hydrogen available for fuel usage.A working cell from Switzer’s research, with gas evolution.

Fuel Cell Carts Deliver Power to Airplane Galleys

Airplane galleys consume a huge amount of power. Additional power units may soon come to the rescue: housed inside trolley carts in the galleys, these units deliver both supplemental power and thus uncouple the power to the cabin and the kitchen from power supplied to the rest of the aircraft. In addition, the cart does not need new approval every time the airplane gets a retrofit or a facelift.Housed in a trolley cart, the additional power supply for airplanes is easy to stow.

Molecules Could Harvest Sunshine for a Rainy Day

The Sun is a huge source of energy. In just one hour, planet Earth is hit by so much sunshine that humankind could cover its energy needs for an entire year if only we knew how to harvest and save it. A student at the University of Copenhagen has researched his way to a breakthrough that may prove pivotal for technologies trying to capture the energy of the Sun, and saving it for a rainy day.

Electrical Power Converter Accepts Power from Renewable Energy

Engineering researchers at the University of Arkansas have invented a novel electrical power converter system that simultaneously accepts power from a variety of energy sources and converts it for use in the electrical grid system. The U.S. Department of Energy is seeking licensing opportunities for potential commercialization.
