As blades grow larger, the amount of reinforcement increases in a logarithmic progression. For a 1.5-MW turbine, typical blades should measure 110 ft to 124 ft (34m to 38m) in length, weigh 11,500 lb/5,216 kg and cost roughly $100,000 to $125,000 each.
RSS Feeds. Nitrogen (N 2) is the most abundant gas in Earth's atmosphere, including the troposphere. This cartoon also depicts several other tropospheric gases, including oxygen (O 2), carbon dioxide (CO 2), water vapor (H 2 O), methane (CH 4), sulfur dioxide (SO 2), and carbon monoxide (CO).

Oxygen: the essentials. Oxygen is a Group 16 element. While about one fifth of the atmosphere is oxygen gas, the atmosphere of Mars contains only about 0.15% oxygen.Oxygen is the third most abundant element found in the sun, and it plays a part in the carbon-nitrogen cycle, one process responsible for stellar energy production.n the other hand, ozone is an important component of the atmosphere (the ozone layer) and helps to shield us from harmful ultraviolet rays from the sun. Oxygen gas (dioxygen, O 2) makes up 21% of the atmosphere by volume. It is the most abundant element in the earth's crust (followed by silicon).
