  • Biodiesel is considered a non-flammable and non-combustible product.
  • Optimally, dedicated biodiesel tanker trucks and associated transfer components should be used to transport biodiesel. If non-dedicated equipment is used, it must be washed, rinsed, drained and dried prior to biodiesel loading in order to avoid any cross-contamination.

Benefits and Challenges - 0 views

  • Fuel cell systems are not yet as durable as internal combustion engines, especially in some temperature and humidity ranges.
  • FCVs are currently more expensive than conventional vehicles and hybrids. Manufacturers must bring down production costs, especially the costs of the fuel cell stack and hydrogen storage, to compete with conventional technologies.

Revolution Green: A True Story of Biodiesel in America - 0 views

  • There are over 180,000 fueling stations nationwide. About 40% of those service petroleum diesel fuel, and less than 1% service biodiesel.
  • Biodiesel is simple to use and requires no costly engine conversions or infrastructure changes to the current delivery system of diesel fuel.

Group items matching "history geothermal" in title, tags, annotations or url - qmstech2... - 0 views

  • The word geothermal comes from the Greek words geo (earth) and therme (heat). So, geothermal energy is heat from within the Earth. We can recover this heat as steam or hot water and use it to heat buildings or generate electricity. Geothermal energy is a renewable energy source because the heat is continuously produced inside the Earth. ... Cancel

Visual Health Effects and Wind Turbines - The Society for Wind Vigilance - 0 views

  • In addition to noise pollution wind turbines also have visual burdens.
  • The health impact of visual burdens cannot be underestimated. An epidemiology study conducted by World Health Organization determined a “bad view out of window” increased the risk for depression by 40%. The same study also demonstrated disturbance by noise and sleep disturbance by noise increased the risk of depression 40%, and 100% respectively.
  • Wind turbines produce noise and visual burdens.

  • Scientific research confirms visuals impacts can adversely affect human health.
  • Wind turbine shadow flicker has the potential to induce photosensitive epilepsy seizures however the risk is low with large modern models and if proper planning is adhered to.
  • Wind turbine shadow flicker induced adverse human health effects include annoyance and/or stress.

How Is Wave Energy Used to Generate Electricity? | eHow.com - 0 views

  • Earth is composed mainly of bodies of water---about 71 percent of the earth's surface is water. Ninety-seven percent of that is found in the oceans. Because the earth's surface is curved, the sun heats it unevenly. This causes winds to blow across the water and generate waves. The sun and moon also exert their gravitational pull on the earth, triggering wave-producing tides. Wave motion energy can be harnessed and generated into electricity.

Hydrogen Fuel Cell | Yale Office of Sustainability - 1 views

  • At 250 kilowatts, the fuel cell produces 40-50% of the electricity for the Environmental Science Center. Its electricity production alone is 47% effective, and the addition of heat recovery allows for up to 60% efficiency
  • While designed to run on pure hydrogen, Yale’s fuel cell is actually powered by natural gas, 80% of which is usable hydrogen. The fuel cell takes in natural gas and water and produces water, electricity, and hot air.

Renewable Energy, Other sources of Renewable Energy - 0 views

  • "Worldwide, approximately 3000 gigawatts (1 gigawatt = 1 GW = 1 billion watts) of energy is continuously available from the action of tides.
  • The best areas are on the eastern sides of the oceans (western side of the continents) between the 40 and 60 latitudes in both the northern and southern hemispheres.
  • While the "wave power at deep ocean sites is three to eight times the wave power at adjacent coastal sites," constructing and mooring the site and transmitting the electricity to shore would be prohibitively costly.

  • There is a handful of wave energy demonstration plants operating worldwide, but none produces a significant amount of electricity.

  • .In this form of Tidal Power,a Barrage is built near the coast where water is collected during the periods of high tides.During low tide the barrage allows the water from the reservoir to move towards the ocean or sea.The potential energy of the water at a higher level is converted to electricity using Turbines.

Uses of Wind Energy | eHow.com - 2 views

  • For hundreds of years mankind has been making use of the energy and power generated by wind. Whether it has been to travel the world, manufacture products, or in the modern age to generate electricity, wind has provided the means. And while there have been dozens of different methods over the years, new technology is still being invented to make even further use of this ancient power source.
  • Windmills were one of the second most widespread uses of wind energy. The variety of uses that windmills were put to included grinding grain, as well as pumping water, up until the industrial revolution where the windmill was mostly replaced by the steam engine.

Wind farms can cause climate change, finds new study - Telegraph - 0 views

  • Wind farms can cause climate change, according to new research, that shows for the first time the new technology is already pushing up temperatures.
  • Usually at night the air closer to the ground becomes colder when the sun goes down and the earth cools. But on huge wind farms the motion of the turbines mixes the air higher in the atmosphere that is warmer, pushing up the overall temperature.

      What this means is that close to the wind farm there is a local warming, not a global impact.
