geothermal potential future

shared by dpurdy on 08 Nov 11 - No Cached
  • According to the government, geothermal has the potential to supply the United States with 20% of our electricity needs.
  • The capital cost of geothermal development is expensive, however; 2/3rds are drilling costs. Yet as we overcome some of these technology challenges and make the process more standardized it is believed that geothermal can supply up to 20% of the United States electricity needs by 2050. But innovation and investment in initial steps need to happen now.

  • Even normal
  • gasoline vehicles can operate on a 10 percent ethanol blend with no problems. Diesel cars and trucks can run on biodiesel, though older models may need to have their fuel lines and gaskets replaced with modern synthetic materials, since biodiesel is a solvent
  • and use of biofuels to power aircraft is expected to increase substantially in the next decade. Because current biofuel production relies heavily on crops that also function as food or livestock feed, emphasis is on developing new sources that don't cause deforestation and compete with food production

  • Small engines, like those found in lawn mowers and chainsaws, can use ethanol blends up to 10 percent without problems. The barrier to using higher blends, up to 20 percent, has more to do with manufacturers' warranties than limitations of the technology

  • Types of soot include: Wet Smoke Residues - Result from smoldering fires with low heat. Residues are sticky, smeary and with pungent odors.  Smoke webs can be difficult to clean. Dry Smoke Residues - Result from fast burning fires at high temperatures. Residues are often dry, powdery, small, nonsmeary smoke particles. Protein Residues - Virtually invisible residues that discolor paints and varnishes.  Extreme pungent odor. Fuel Oil Soot - Furnace puff backs distribute fuel oil soot. Other Types of Residues - Tear gas, fingerprint powder, and fire extinguisher residues also need cleanup.

Wind - Wikipedia, the free encyclopedia - 0 views

en.wikipedia.org/Wind

shared by dynesbri97 on 13 Mar 12 - Cached
  • Wind is the flow of gases on a large scale. On Earth, wind consists of the bulk movement of air. In outer space, solar wind is the movement of gases or charged particles from the sun through space, while planetary wind is the outgassing of light chemical elements from a planet's atmosphere into space. Winds are commonly classified by their spatial scale, their speed, the types of forces that cause them, the regions in which they occur, and their effect. The strongest observed winds on a planet in our solar system occur on Neptune and Saturn.
  • Winds can shape landforms, via a variety of aeolian processes such as the formation of fertile soils, such as loess, and by erosion. Dust from large deserts can be moved great distances from its source region by the prevailing winds; winds that are accelerated by rough topography and associated with dust outbreaks have been assigned regional names in various parts of the world because of their significant effects on those regions. Wind affects the spread of wildfires. Winds disperse seeds from various plants, enabling the survival and dispersal of those plant species, as well as flying insect populations. When combined with cold temperatures, wind has a negative impact on livestock. Wind affects animals' food stores, as well as their hunting and defensive strategies.
  • Wind is caused by differences in pressure. When a difference in pressure exists, the air is accelerated from higher to lower pressure. On a rotating planet, the air will be deflected by the Coriolis effect, except exactly on the equator. Globally, the two major driving factors of large-scale winds (the atmospheric circulation) are the differential heating between the equator and the poles (difference in absorption of solar energy leading to buoyancy forces) and the rotation of the planet. Outside the tropics and aloft from frictional effects of the surface, the large-scale winds tend to approach geostrophic balance. Near the Earth's surface, friction causes the wind to be slower than it would be otherwise. Surface friction also causes winds to blow more inward into low pressure areas.

shared by dpurdy on 20 Jan 12 - No Cached
  • Coal generates 2,249 pounds of carbon dioxide, 13 pounds of sulfur dioxide and 6 pounds of nitrogen oxides for every megawatt hour of energy generated.
  • Biomass produces nitrogen oxides and small amounts of sulfur dioxide. The amount of carbon dioxide produced does not exceed that of the Earth's normal carbon cycle and is considered negligible.

    "What is sustainability? Sustainability is based on a simple principle: Everything that we need for our survival and well-being depends, either directly or indirectly, on our natural environment.  Sustainability creates and maintains the conditions under which humans and nature can exist in productive harmony, that permit fulfilling the social, economic and other requirements of present and future generations."

    "The hydrogen economy is a proposed system of delivering energy using hydrogen. The term hydrogen economy was coined by John Bockris during a talk he gave in 1970 at General Motors (GM) Technical Center.[1] Hydrogen advocates promote hydrogen as a potential fuel for motive power[2] (including cars and boats), the energy needs of buildings and portable electronics. Free hydrogen does not occur naturally in quantity, but can be generated by steam reformation of hydrocarbons, water electrolysis or by other methods. Hydrogen is thus an energy carrier (like a battery), not a primary energy source (like coal). The feasibility of a hydrogen economy depends on issues of electrolysis, energy sourcing, including fossil fuel use, climate change, and sustainable energy generation."

    "The history of geothermal power can be traced back to over 10,000 years ago to the American Paleo-Indians at their settlement in hot springs. This history has been uncovered through the use of archeology and shows the Indians used the hot springs for activities including, bathing and heating. It is also believed the springs were seen as a healing source."
