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.

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.

Energy Efficiency in Machine Tools

Discussions of the efficient use of energy have become more frequent in many sectors of industry. Machine tools comprise numerous motors and auxiliary components whose energy consumption can vary strongly during machining. The main spindle drive, for example, and the coolant system work near their rated power during roughing with a high stock removal rate, while the power consumption during finishing is significantly lower. There is a very close interdependence between the individual components and subassemblies of a machine tool and aspects of productivity and quality. From a detailed examination of manufacturing processes to the power consumption of individual components, potential for savings can be evaluated and measures can be defined for the efficient use of energy.

Variable-Sweep-Wing Aircraft Configuration

There are significant improvements in structural, aerodynamic, and energy efficiency. Ames Research Center, Moffett Field, California Efficient aircraft designs are increasingly desired in order to support the continued growth of the air transportation industry. Continued expansion of this vital mode of transportation is threatened due to concerns over ever-increasing emissions, noise, and the demand for fuel. Current airport runway, ramp, and terminal facilities are increasingly constrained by encroaching growth and neighborhood environmental issues. The challenges associated with ever-increasing demand for air travel will require the development of aircraft that can fly efficiently over wide speed ranges, minimize their environmental impacts, offer the potential for sizing and growth relative to market demand, and make efficient use of constrained airport and airspace resources.
