Wind Energy Gets a Second Breath of Life (News Note)

Posted on by

wind trubines

Have you been following the “fiscal cliff” debacle?  Unless you spent the holiday season in a cave, the answer is probably YES.  One interesting detail tucked away in the recently passed compromise legislation is the renewal of the Renewable Energy Production Tax Credit (PTC) for wind power, now extended through 2013.

The PTC awards a 2.2 cents per kilowatt hour tax credit for wind, geothermal and closed-loop biomass and 1.1 cents per kilowatt hour for other renewable energy technologies. This lasts for 10 years for most technologies, including wind.  Alternatively, companies can request a lump-sum payment of 30% of the wind construction cost as a tax credit once the wind turbine starts producing power.

Also new for 2013, companies are allowed to claim the credit if construction begins before the end of this year.  Previously, the facility had to be placed in service (i.e., operating) before the end of the year.

According to the folks at Green-Buildings.com, the extension of the renewable energy credit should boost wind energy construction, at least for the first half of 2013.

What is your opinion of the tax incentives for wind energy?  Yeah or Nay? Share in the comment section, below.

Engineers: Here’s how to Securing your Mobile Device from Cyber-Attacks (guest post)

Posted on by

smartphone iconToday, a very important post from guest blogger Silvia Brook.  Silvias writes about home and cyber security for homesecurity.org. When she’s not writing, Silvia enjoys biking with her friends or cooking a new recipe from her compendium of cookbooks.

————————-

Believe it or not, cyber security is still a big issue in the tech industry. It seems as though every year a new electronic device is released by one of the major hardware developers, and yet every year consumers who buy those same devices fall prey to a host of viruses, glitches, and malware. A tablet released this year may get hit with just as many (if not more) viruses as they model that preceded it the year before.

Part of why that’s the case is because malicious applications are changing and evolving at the same rate as the new devices that they target. Developers on both sides of the equation are fighting to make the better application—those who design security apps and protection software will try to keep your information, while hackers will try just as hard to take it away.

A recent assessment of the Android OS’s newest virus protection software might explain this problem. The new smartphone OS—Android 4.2—has a built-in malware scanner for apps. A computer scientist at North Carolina State University decided to see how this new scanning software stacked up third-party virus protection apps in a test that pits them all against the latest malware targeting smartphones. The study found that the Android OS app scanner caught malware content only about 20% of the time. The third-party security apps fared much better, some of which caught malware nearly every time.

What are we supposed to do with this information? Google seems to have trouble designing a competent virus scanning application for its own line of smartphones, all of which seem at least vulnerable to potential viruses according to the above report. If that’s the case, then how can people expect to put sensitive information (emails, finances, photos, etc.) on their smartphones?

I think the most important takeaway is that cyber security should be taken seriously by people who use mobile devices on a regular basis. There really are malicious apps out there that could do some serious damage to smartphones and tablets.  Design professionals such as engineers and architects who rely on their electronics for mobile work  are best off defending themselves from such annoyances with third-party apps designed by professionals with a proven track record.

Below are two apps by such developers which have received nothing but glowing reviews from critics.

Avast!

Avast! is a comprehensive software that addresses many key cyber security concerns. For one thing, the software will help users track their smartphones or tablets should they ever get lost or stolen. Avast! will let users locate their misplaces phones via GPS and send SMS messages to it should they want to address whoever has it. Of course the software also protects mobile devices from malware apps and websites that could be packing a nasty virus by scanning every app before it’s loaded. Avast! also allows users to build a firewall for their mobile devices should they suspect that hackers want to tamper with their data. In other words, Avast! is the whole security package for the Android, and it’s free!

F-Secure Mobile Security

F-Secure is an acclaimed security software company, protecting both home computers and mobile devices all sorts of cyber security threats. F-Secure will ensure that mobile users can browse the web safely without fear of encountering malware; the service will also scan incoming apps and data for any potential viruses that could compromise the safety of the device. Like Avast!, F-Secure also has a feature that will help users track down their mobile device should it be misplaced or stolen (and users can erase their data remotely it they suspect that someone has access to their information). F-Secure has a subscription fee, and it’s only available for Android users.

Melissa here again.  What about you?  Do you have a favorite cyber security app?  Depending on how much you work in the Cloud, you should!

Here’s to Your Family’s Nuts!

Posted on by

Merry Christmas and Happy Holidays to all of my blog readers!  Rather than yet-another-boring-tree photo, I thought I’d share this photo of a squirrel and his nuts, because *every* family has at least a few nuts, right?  Here’s hoping  you get to spend some down time this season with your family, nuts & all!

Engineering for the Earthquake- Dumbarton Bridge (News Note)

Posted on by

Engineers who design in earthquake-prone areas know that they need to design the seismic loads of their bridges to account for potential massive shifts during a quake.  (This is what is legally known as the professional standard of care, which takes into account what similar engineers, in the same conditions and community, would consider acceptable design)**.  The Dumbarton Bridge, the farthest south bridge across the San Francisco Bay, is no exception to this rule.

Currently, the Dumbarton Bridge is being renovated as part of the San Francisco Bay Area Toll Bridge Seismic Retrofit Program.  When the bridge is finished (expected in early 2013), the bridge will increase its ability to move from 20 inches of lateral movement to as much as 42 inches of lateral movement.

Dumbarton BridgeThe retrofit includes friction pendulum bearings designed by Earthquake Protection  Systems, Inc., which will isolate the superstructure from two pier structures where the main span of the bridge meets the approach structures.  A concrete taper will be used from the joints to the main span to ease the transition, as the approach span is 5 inches lower than the main span.

According to Earthquake Protection Systems president Victor Zayas, in a statement to Roads & Bridges magazine, the most critical part of the bearing is the bottom lining, which is a self-sacrificing, solid-lubricant polymer composite that was developed based on earlier research done by NASA in the 1960s.

How Green Building is Evolving Into Something Bigger (guest post)

Posted on by

Texlon green buildingToday, a guest post by the folks at Vector Foiltec.  Vector Foiltec  invented the use of Texlon (ETFE), and have developed the use of this innovative technology worldwide in the design and constructive industry. Some of the world’s most impressive offices, stadiums, and transport buildings have been developed by Vector-Foiltec.

 

Recent years have seen a surge in the number of designs and commissions of green buildings by designers and architects. All around the world, green, eco-buildings are becoming the benchmark of expectation. Not so long ago, a green building would standout because of how different it was. It would be something new, even quirky, and something unfamiliar that not everyone was comfortable with.

Those days have long gone, however, with a realisation that green building is the way forward, with environmental benefits as well as those attached to finances and quality of life improvements.

Eco-friendly buildings aren’t yet at the stage where we can celebrate them as the final frontier of construction, however. Yes, the new designs of buildings and the materials used certainly mean that an office block can be carbon neutral, but are they sustainable in other ways? The evolution of green building, now and in the future, will center firmly around the ability of designers and construction professionals to create buildings that are not only eco-friendly, but sustainable for use in terms of how they deal with extreme weather or other natural events, such as hurricanes and earthquakes, for example.

Always Working

Meeting the challenge of ensuring that a building can ‘always work’ has been an obstacle for designers. Placement of windows, for example, and the materials used within construction means that issues such as insufficient daylight are no longer an issue.

But what about when there is a power cut, or problems with the water supply?

To reach that searched for ‘final frontier’ that we mentioned earlier, designers need to make a building that can stand independently of central supplies such as electricity and water. This creates new challenges around energy recovery and storage as well as on-site water recycling, but it is possible to achieve results.

When a building is at the level where ‘always working’ has been achieved, a hurricane or other severe weather will then be minimally disruptive to it.

‘Always working’ represents a model for a truly sustainable building.

How It’s Made

The materials used are often the central focus of eco-building and have been responsible for many of the positive results seen in recent years. However, there is still a focus on developing eco-friendly construction materials further, and using them to best effect within a building.

So strong is this focus that there are now homes being constructed from ‘cob,’ and other similar compounds around the world. The great thing about these? They are lightweight, resistant to fire and earthquakes, and also stand up to events such as flooding and powerful winds.

The very meaning and identity of ‘green building’ is changing fast. Architects and designers that combine environmental benefits with true sustainability over the coming years are sure to find themselves in high demand.

Thoughts, comments?  Know of a ‘cob’ home that we should get pictures of?  Post in the comments section below.
