AROA’s Second Solar Tulip Power Plant Springs Up in Spain

By Andrew Michler

Clean tech company AROA recently installed their second energy-generating Solar Tulip power tower in Spain, and the soaring flower-shaped power plant just went online this week. The beauty of the system stems beyond the elegant solar energy capturing tower – the system is designed to be modular, unlike any other concentrated solar power (CSP) electrical generator out there. The system also uses much less water than steam solar generators, enabling it to conserve precious resources on its hot desert site.

World's largest offshore wind farm opens for business

By

Walney wind farm off the coast of Cumbria in the UK yesterday became the world’s largest offshore wind facility. One hundred and two turbines over 73 sq km (28 sq miles) provide a maximum output of 367.2 MW. It’s claimed the facility will provide enough power for about 320,000 homes – half as many again as the total number in Cumbria.

The project’s first phase, Walney 1, has been providing power since January 2011 from 51 137-meter-high (450-ft) turbines, each with a 107-m (350-ft) rotor diameter. The completed second phase, Walney 2, adds another 51 turbines of even greater size to the installation. These 150-m (492-ft) tall turbines have three 18-tonne (19.8-short ton) blades with a total diameter of 120 m (394 ft). Despite the differing dimensions, all turbines are Siemens-made 3.6 MW turbines. All told a single wind turbine weighs a hefty 550 tonnes (606 short tons). The Walney 2 installation was completed in an impressively tight six-month window.

Why Google Invests in Clean Energy

Email, RSS Follow

Last year, Google invested more than $915 million in clean energy projects — solar, wind and transmission.

That’s a lot of money, even for Google, which had $38 billion in revenues in 2011. The investments don’t appear to be core to the company’s mission of organizing information, and they have attracted criticism, as well as some careless reporting, implying that the Internet giant is exiting the alternative energy business.

K-TOR has added a new portable charging device to its lineup. The new Power Box puts your legs to work toward converting kinetic energy to electricity. Use it enough and you might just get your weekly workout. It is quite simply a pedal-powered generator equipped with a dual-pronged outlet so that you can plug in an AC adapter and charge your device directly from your leg power. The box works for devices rated 20W and below, including low-power netbooks, tablets, smartphones, video devices and portable game systems.

Smartphones of today

The world of cellphones is expanding with new models being launched almost every day. Back in 1973, when the first cellphone was made; it was a bulky object with not many functions other than that of making and receiving calls. Now, cellphones have become like mini computers with multipurpose cameras, capable of storing substantial amounts of data, recording videos and music, linking to the internet, playing games and a whole host of other features. These phones fall under the category of smartphones owing to their intelligent capabilities. So essential have they become to consumers that the third quarter of the year 2011 saw 115 million units of these phones being sold worldwide.

A Wave Power Generator with a Twist: It Generates Electricity On Dry Land

A Wave Power Generator with a Twist It Generates Electricity On Dry Land

Email, RSS Follow

A relatively new* type of reciprocating wave-powered electricity generator called Searaser has been developed and is moving forward. Searaser, acquired by Ecotricity, is not a typical wave power plant.

The first peculiarity is that it does not generate electricity out at sea. Due to the fact that waves move up and down in the ocean, they can continuously move a float attached to a reciprocating pump that can pump water through a water-powered onshore electricity generator for the sake of keeping the electrical parts of the system out of the water.

As Damian Carrington of The Guardian notes, its is a bit like an aquatic “bicycle pump.”

Dutch firm Govaert and Vanhoutte Architects have transformed a beautiful windmill and adjacent farm building into the innovative D-hotel in Kortijk. An iconic symbol of the Netherlands, the windmill rises on a farm site around a series of buildings formerly used on the farm, which are met by modern glass block structures. The adaptive reuse project is decorated with themes focused around art, film and music, and it won the architects third place in Hotel Et Lodge magazine’s international competition.

Microbubbles Enable More Efficient Production Of Algae Biofuels

Email, RSS Follow

Algae biofuel is one of the most promising alternative fuels on the market – so far we’ve seen cars and even planes adapted to run on it. The main drawback thus far has been high production costs and energy usage – until now. Using a new “cost-effective harvesting method” featuring microbubbles, a team from the University of Sheffield believe they have found a way to make algae a more commercially viable fuel source.

What's Next Low cost wind turbines for the developing world

As we know it

In the present era, the renewable energy realm has a share of about 19 percent in worldwide electricity generation. Now, for the uninitiated, this may seem to be a paltry figure, but if we go by statistical expansion, the ongoing phase is certainly propitious for sustainable output. As a matter of fact, total power capacity from renewable sources momentously exceeded the world capacity of nuclear power for the first time in 2011. In this regard, the major progression was actually witnessed in the case of wind power, with a whopping increment from 6.1 GW in 1996 to more than 200 GW by 2011.
