  • The hydrogen fuel cell operates similar to a battery. It has two electrodes, an anode and a cathode, separated by a membrane. Oxygen passes over one electrode and hydrogen over the other. The hydrogen reacts to a catalyst on the electrode anode that converts the hydrogen gas into negatively charged electrons (e-) and positively charged ions (H+).

  • Biofuels or biodiesels are fuels that are, in essence, biodegradable and non-toxic. They are manufactured from vegetable oils, waste cooking oils, animal fats or tall oil (a by-product of the pulp and paper industry).

  • Think of them as big batteries, but ones that only operate when fuel—in this case, pure hydrogen—is supplied to them.

  • Hydrogen is a highly flammable chemical element which occurs in great abundance throughout the universe. In fact, hydrogen makes up approximately 75% of the universe, by volume, and it appears in a very large number of compounds, especially those which make up various organic materials.

hydrogen cost

shared by dpurdy on 12 Mar 12 - No Cached
  • Price projections vary among fuel cell developers, but most are targeting costs below $1,500/kW
  • Maintenance costs of a fuel cell are expected to be comparable to that of a microturbine, ranging from $0.005-$0.010/kWh (based on an annual inspection visit to the unit).
  • At the current price, units are only used in high value, "niche" markets where reliability is premium, and in areas where electricity prices are very high and natural gas prices are low.

Renewable Solar Energy: How is Wind Formed - 0 views

  • Wind is formed by the indirect effect of the sun on the Earth’s surface. There is a reasonable explanation why is it so. As the sun shines, the Sun heats the Earth's surface; the air near ground level gets hot and rises up. Cold air at higher altitudes replaces it. At nighttime the process is reversed. This is  in principal how is wind formed on Earth.
  • This process of hot air rising and colder air sinking, causes high and low air pressure areas and results in wind formation. The more the pressure changes in an area, the faster the wind speed will be. If two areas are close to each other, pressure difference will cause higher wind speed to be produced compared to areas that are far apart from each other. This is how the wind is formed on Earth and this phenomena is known as vertical wind formation

  • All winds are caused by differences in air pressure, which are usually caused by the sun. When high air pressure flow into low air pressure, it creates wind.Our planet turns around the Sun on an axis with a 23 degree tilt towards the North Star. The difference of heating on the surface of the Earth (between the equator and the pole) causes a mass of hot air to go up and to displace colder air toward the bottom - this all causes movement in the mass of air that is contain in our atmosphere.

  • 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 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.
