Contra-rotation, using two rotors one behind the other, driving the two halves of an electrical generator. Thus creating a true "Wind Turbine".
Ocean plankton restoration offers a powerful remedial approach to global warming that also rescues critical ecosystems, profitably finances itself, and can help allay further resistance to CO2 regulation based on economic qualms.
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.
The February eMagazine covers topics including Geothermal and Solar Energy, Hydrogen Production, Supergreen Ship Building and Plankton Power long with some technical papers and conference reports.
In this article, we offer a few tips on growing houseplants without the use of chemical fertilizers and pesticides. That way, you can clean the air of your home or office without the potentially harmful effects of chemicals!
Passive solar design takes the pressure off conventional heating and cooling systems.
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.
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.
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.
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
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
Find out just how great if feels to own a power plant on wheels. Anywhere you choose to roam - in the field or close to home - Hard at work, or having fun... Get Your Power From The Sun!
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.
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.
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.
