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.

How much heat do you really need?
Passive solar design takes the pressure off conventional heating and cooling systems.
Hydrogen Production Technology ― Light-Powered Generation
Phoenix funding is employed in the basic photoelectrochemical design of innovative, complex "molecular machines" that can split water into its hydrogen and oxygen components by harnessing energy sourced from the complete solar light spectrum.
New Players in the Hydrogen Game
By setting demanding goals, these pioneering governments are a forging a path toward the hydrogen economy. Hopefully others will take note and follow their lead.
NextFest 2006: The Future of Earth Toys
In addition to showcasing some of the globe's most advanced robotics, NextFest 2006 also included some of the world's most advanced environmentally friendly gadgets.
Principal Voices Speak: Renewable Energy Paramount
According to the program introduction, alternative energy accounts for one-half of one percent of all energy used today. Breaking free of the hydrocarbons, which accounts for a whopping 80 percent of energy used, has truly become a stated geopolitical concern
REVERSING CLIMATE CHANGE?
I would like to point towards one combination of existing technology that I am convinced could actually do the job of lowering atmospheric carbon concentrations and thus reverse climate change

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
