Commercial Hot Water Technology Offers 400% Efficiency
The system is connected to refrigeration grade tubing that is placed in direct contact with the renewable heat source in the upper 100 feet of the earth's surface. The ground temperature is stable year round, and in the U.S., ranges from 42 degrees at the Canadian border to 78 degrees in the southern extreme.

Studies on Ideal and Actual Efficiency of Solar Polymer Electrolyte Fuel Cell
Among the different types of fuel cells, the PEMFC is more advantageous because of its operation condition. To satisfy the world energy thirst an integrated hydrogen production system and utilization unit must be developed.
SuperGreen Ships and Barges
Not unlike washing machines, clothes, cars, and buildings, ocean going ships eventually wear out and require replacement. The next generation of ships may well require onboard ballast water treatment capability and double hulls.
TERRESTRIAL SOLAR CELL SURPASSES 40 PERCENT EFFICIENCY
This technology will continue to dramatically reduce the cost of generating electricity from solar energy as well as the cost of materials used in high-power space satellites and terrestrial applications.
3 Dimensional Solar Cells
Solar3D, Inc. is developing a breakthrough 3-dimensional solar cell technology to maximize the conversion of sunlight into electricity. Up to 30% of incident sunlight is currently reflected off the surface of conventional solar cells, and more is lost inside the solar cell materials. Inspired by light management techniques used in fiber optic devices, Solar3D's innovative solar cell technology utilizes a 3-dimensional design to trap sunlight inside micro-photovoltaic structures where photons bounce around until they are converted into electrons
