Rainforests Determine Global Atmospheric Circulation, Study Says

Mila Luleva — Thu, 31 Jan 2013 18:43:14 +0000

It is a well-known fact that wind is created due to differences in temperature- when warm air rises and it is replaced by cool one. What is not so well-known, however, is that winds that control atmospheric circulation are formed thanks to condensation of moisture, and a big part of this process occurs over rainforests. […]

Study Describes Wind Power Dependence on Atmospheric Stability

Ovidiu Sandru — Thu, 19 Jan 2012 17:34:53 +0000

Scientists from LLNL, University of Colorado at Boulder and the NREL have recently assessed the performance figures of a wind turbine producing energy on the East Coast, and found how power depends on atmospheric stability. “The dependence of power on stability is clear, regardless of whether time periods are segregated by three-dimensional turbulence, turbulence intensity […]

A recent experiment performed by a team of researchers from the Delft University in Netherlands (aka country of wind mills) used kites to transform the wind power into electricity. They created 10kW of electricity with their project, which is sufficient to power about 10 households with normal energy requirements.

StatoilHydro to Build World’s First Floating Wind Turbine

Ovidiu Sandru — Thu, 29 May 2008 07:16:06 +0000

The Norwegian state oil company StatoilHydro is about to build “Hywind”, the world’s first functional floating wind turbine, and to test it for two years offshore Karmi¸y. They have developed HyWind based on familiar concrete constructions floating from North Sea oil installations. The rotor blades on their floating wind turbine will be enormous: 80 meters […]

Jet Engine-Like Wind Turbine – 4 Times More Efficient

Ovidiu Sandru — Mon, 31 Mar 2008 07:28:19 +0000

Here's an invention that should capture more of the world's attention, because it can capture more of the world's winds. Flodesign's "jet engine"-shaped wind turbine has a slightly different way of seeing the wind flow, and by this it is three to four times more efficient.

Bluenergy: Wind and Solar Power in One Piece

Ovidiu Sandru — Tue, 26 Feb 2008 17:32:59 +0000

The BSWT is a vertical wind turbine based on sailing engineering. The wind rotor is rotated by two spiral-formed vanes. For best performance, these vanes are covered in solar cells, so that sun and wind produce electricity as one element. The BSWT installation costs relatively little, produces no noise or significant shadowing, can be easily […]

Levitating Magnetic Wind Turbine – efficiency made in China

Ovidiu Sandru — Sun, 10 Feb 2008 20:18:23 +0000

What could result if you combine magnetic power, wind power, and a huge-sized facility? Energy!!! It even results a lot of energy. How do you call it when you put in 53 million dollars and get 214 million dollars out of it? Profit! So… profit+energy=CHEAP! The chinese have done it again! They are now building […]

Recycle your boost: highway-based wind turbines

Ovidiu Sandru — Wed, 06 Feb 2008 09:31:22 +0000

I found a blog that describes an extraordinary idea for making electricity from wind. It is a highway-based wind turbine, and I have never heard anything like that before. The idea is a student’s semester project. The original site is written at the end of the article. Parasite- an organism that lives on or in […]
