New Material Increases Lifetime of Solar-Powered Electrons

Nobody wants a laptop computer that stops working when a cloud passes by. Storing sunlight as fuel that can be later used to drive fuel cells requires new materials. Scientists demonstrated just such a material by combining two oxides on the atomic scale.

A New Generation of Cooling

Energy efficiency is key to the total cost of ownership of enclosure climate control solutions, and electricity consumption is a major element of operating costs. Hybrid technology, developed and patented by Rittal, combines conventional compression cooling, similar to what has been used in traditional air conditioners, with a heat pipe. The heat pipe uses evaporation of a working fluid in an evacuated tube.

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.

Solar-Powered Water Purification System Supports Remote Village

For nearly two years, residents of the remote Mexican village of La Mancalona, most of whom are subsistence farmers, have operated and maintained a solar-powered water purification system engineered by researchers at the Massachusetts Institute of Technology (MIT).

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.
