Wind Energy | Future of Renewable Energy | Full Documentary
Wind Energy | Future of Renewable Energy | Full Documentary Machines 13 Views • 2 months ago

Wind power is one of the fastest-growing renewable energy technologies. Usage is on the rise worldwide, in part because costs are falling. Global installed wind-generation capacity onshore and offshore has increased by a factor of almost 75 in the past two decades, jumping from 7.5 gigawatts (GW) in 1997 to some 564 GW by 2018, according to IRENA's latest data. Production of wind electricity doubled between 2009 and 2013, and in 2016 wind energy accounted for 16% of the electricity generated by renewables. Many parts of the world have strong wind speeds, but the best locations for generating wind power are sometimes remote ones. Offshore wind power offers tremendous potential.

Wind turbines first emerged more than a century ago. Following the invention of the electric generator in the 1830s, engineers started attempting to harness wind energy to produce electricity. Wind power generation took place in the United Kingdom and the United States in 1887 and 1888, but modern wind power is considered to have been first developed in Denmark, where horizontal-axis wind turbines were built in 1891 and a 22.8-metre wind turbine began operation in 1897.

Wind is used to produce electricity using the kinetic energy created by air in motion. This is transformed into electrical energy using wind turbines or wind energy conversion systems. Wind first hits a turbine’s blades, causing them to rotate and turn the turbine connected to them. That changes the kinetic energy to rotational energy, by moving a shaft which is connected to a generator, and thereby producing electrical energy through electromagnetism.

The amount of power that can be harvested from wind depends on the size of the turbine and the length of its blades. The output is proportional to the dimensions of the rotor and to the cube of the wind speed. Theoretically, when wind speed doubles, wind power potential increases by a factor of eight.

Wind-turbine capacity has increased over time. In 1985, typical turbines had a rated capacity of 0.05 megawatts (MW) and a rotor diameter of 15 metres. Today’s new wind power projects have turbine capacities of about 2 MW onshore and 3–5 MW offshore.

Commercially available wind turbines have reached 8 MW capacity, with rotor diameters of up to 164 metres. The average capacity of wind turbines increased from 1.6 MW in 2009 to 2 MW in 2014.

Chicago Dept. of Streets & Sanitation Elgin Pelican Street Sweeper [04.30.2014]
Chicago Dept. of Streets & Sanitation Elgin Pelican Street Sweeper [04.30.2014] Machines 12 Views • 2 months ago

It's finally Springtime in Chicago, at least according to the calendar, and that means it's time for street sweepers to tackle Chicago's streets and clear the muck of dead leaves left over from the fall that accumulated along with garbage along the city's curbs on main thoroughfares and residential streets. We received one Hell of a pounding this year from Mother Nature with a prolonged winter that saw near-daily snowfalls that accumulated to total the third-snowiest winter on record in Chicago history. I know I speak for many Chicagoans when I say that I'm glad to see the grass and the ground that was too often covered with a layer of white this winter.

Now back to the street sweeper itself, here's some information off Elgin's website:

The Elgin Pelican broom sweeper is a three-wheel mechanical sweeper based on one of the original street sweeper designs, which has been continuously improved since 1914, meeting the highest sweeper standards. Maneuverability, economy, serviceability and single lane dumping with a sweep system that easily handles heavy compacted dirt and bulky debris are all features of the Elgin Pelican. An isolation-mounted cab provides a cleaner, quieter operation, and the improved 360-degree visibility and easier access for service and maintenance make the Elgin Pelican an industry standard in road sweepers.

The Pelican is now available as an optional alternative fuel sweeper: Compressed Natural Gas (CNG), Liquefied Petroleum Gas (LPG), and Liquefied Natural Gas (LNG). The Pelican also has a waterless dust control option.

The Elgin Pelican is specially suited for applications that require extreme maneuverability due to congested areas, heavy debris such as that found in northern climate spring clean up, and bulky items up to 9" long. The waterless version of this street sweeper can do all this without the use of dust control water, allowing for year around operation and use on water reactive compounds like Portland cement.

Engine: John Deere® 4045TF150 | 55 KW
Dumping Height Max: Variable up to 9 ft. 6 in. | 2895 mm
Sweeping System: Hydraulic
Dump Location: Front
Chassis: Elgin Exclusive

MEGAFACTORIES: Hieneken ||Audio in Hindi ||
Heineken Lager Beer (Dutch: Heineken Pilsener), or simply Heineken (Dutch pronunciation: [ˈɦɛinəkən]), is a pale lager beer with 5% alcohol by volume produced by the Dutch brewing company Heineken International. Heineken is well known for its signature green bottle and red star.

On 15 February 1864, Gerard Adriaan Heineken (1841–1893) got his wealthy mother to buy De Hooiberg (The Haystack) brewery in Amsterdam, a popular working-class brand founded in 1592. In 1873 after hiring a Dr. Elion (student of Louis Pasteur) to develop Heineken-A Yeast for Bavarian bottom fermentation, the HBM (Heineken's Bierbrouwerij Maatschappij) was established, and the first Heineken brand beer was brewed.
In 1875 Heineken won the Medaille D'Or at the International Maritime Exposition in Paris, then began to be shipped there regularly, after which Heineken sales topped 64,000 hectolitres (1.7 million U.S. gallons), making them the biggest beer exporter to France.

Since 1975 most Heineken brand beer has been brewed at their brewery in Zoeterwoude, Netherlands.In 2011 2.74 billion liters of Heineken brand beer were produced worldwide, while the total beer production of all breweries fully owned by the Heineken Group over all brands was 16.46 billion liters globally.Sold in more than 170 countries, Heineken is the world's most international premium beer. It has been incorporated with numerous beer brands from different countries all over the world including, Mexico, China, and Africa.
