Climate Shifts. Global Warming and Climate Change skepticism examined. Green. Green is a color on the spectrum of visible light, located between blue and yellow. It is evoked by light with a predominant wavelength of roughly 495–570 nm. In the subtractive color system, used in color printing, it is created by a combination of yellow and blue, or yellow and cyan; in the RGB color model, used on television and computer screens, it is one of the additive primary colors, along with red and blue, which are mixed in different combinations to create all other colors.
The modern English word green comes from the Middle English and Anglo-Saxon word grene, from the same Germanic root as the words "grass" and "grow".[2] It is the color of growing grass and leaves [3][4] and as a result is the color most associated with springtime, growth and nature.[5] By far the largest contributor to green in nature is chlorophyll, the chemical by which plants photosynthesize and convert sunlight into energy.
It is the most important color in Islam. Shades and varieties In science. Pond-Powered Biofuels: Turning Algae into America's New Energy. Just three years ago, Colorado-based inventor Jim Sears shuttered himself in his garage and began tinkering with a design to mass-produce biofuel. His reactor (plastic bags) and his feedstock (algae) may have struck soybean farmers as a laughable gamble. But the experiment worked, and today, Sears' company, Solix Biofuels in Fort Collins, is among several startups betting their futures on the photosynthetic powers of unicellular green goo. The science is simple: Algae need water, sunlight and carbon dioxide to grow. The oil they produce can then be harvested and converted into biodiesel; the algae's carbohydrate content can be fermented into ethanol.
Both are much cleaner-burning fuels than petroleum-based diesel or gas. The reality is more complex. Solix addresses these problems by containing the algae in closed "photobioreactors"—triangular chambers made from sheets of polyethylene plastic (similar to a painter's dropcloth)—and bubbling supplemental carbon dioxide through the system.
