3-D Printed Dress

This news jumped out at me not because of the stunning application of 3D printing (which I formerly imagined as only within the realm of making toy-like wrenches), but because the advancement it suggests has been made in 3D printing since the technology first became common knowledge. Rather, if the fashion industry has taken off with 3D printing on the runway (where all fashion trends start), then where else have these advancements made their mark?

I did a quick search of applications of 3D printing in international development, which surprisingly came up with very little aside from this 3D4D Challenge, where a team of researchers from the University of Washington won 100,000 USD to make waste plastic as a filament in 3D printing a reality. To be fair, I have more faith that development professionals have thought about the applications of 3D printing in development, and less in their likelihood of posting it on the internet.

Bridging Human Connection and Migration – A Photo Series by John Clang

Tools like Skype have redefined what it means to be in distant relationships or to leave family and friends behind. It has helped people conquer the challenges of distance and shifted the intrinsic costs of travel and migration. Although the benefits of video-calling and high-speed internet can be brought together in an analysis of implications for micro decision-making, migration and – by extension – comparative regional economic prosperity, it is important to keep in mind the deep humanity of the subject.

Innovative Urban Planning or Pricey London Garbage Bin?

Space is expensive, and although this high-tech garbage bin is an effective use of space, I wouldn’t say it’s cost effective. How much time will it save commuters to see the status of the Underground on trash bins, when they can just check it on their phones? Sure, not everyone has an app-hosting phone, but I’d count on it sometime soon.

What else could you put on a garbage bin screen updated in real-time? Image reblogged from This Big City.

Language-learning Redefined

The same concept that is currently digitizing books for free (reCaptcha) is also translating the web (duolingo). On TEDtalks, Luis von Ahn talks about the journey and technology that is helping people simultaneously learn languages and translate the web.

Summary After re-purposing CAPTCHA so each human-typed response helps digitize books, Luis von Ahn wondered how else to use small contributions by many on the Internet for greater good. At TEDxCMU, he shares how his ambitious new project, Duolingo, will help millions learn a new language while translating the Web quickly and accurately — all for free. (Go to duolingo.com)

Market Overview: Telecommunications in the Middle East

Submitted to Professor Kathleen Day
University of Ottawa, May 11, 2012

In the Middle East, overall demand for information and communications technology (ICT) has grown rapidly since 2006. Significant increases in subscriptions to mobile services comprise the bulk of this growth, followed by mobile internet and wired internet. By contrast, fixed-line telephone subscriptions have experienced slow decline across the region, particularly since 2007. This overall upward trend is accompanied by increasing demands for data at high download speeds. Growing volumes of data traffic challenge the current 2G and 3G infrastructures in the region,[1] compromising the quality of service that operators are able to offer when traffic volume is steeply higher than average. Consequently, prices related to telecommunications services have declined in the region. The ITU uses a price basket comprising of prices for fixed-telephone, mobile, and internet services taken as a percentage of average income levels.[2]This method to compare price levels from year-to-year in Middle Eastern countries shows that ICT price levels have dropped overall since 2008 (see Table 1).

Table 1 Countries such as Saudi Arabia, Oman, Lebanon, Jordan and Yemen have experienced declines in overall ICT prices (as a percentage of GNI per capita). Source: ITU (2012). [3]

In response to these trends, public institutions and private operators are investing significantly into improved infrastructure. Larger countries in terms of GNI per capita, such as Saudi Arabia and the United Arab Emirates (UAE), have invested in rolling out 4G LTE mobile networks to be completed within the next 5 years. Less developed countries have invested in improving upon existing 2G and 3G networks. National regulatory institutions have also taken long term measures to respond to expected growth in data traffic volume and subscribers. National regulatory bodies in many countries have deconstructed former monopolies in the past decade (examples include Etisalat in UAE and Qtel in Qatar), giving mobile and internet operating licenses to new entrants (du in UAE and Vodafone in Qatar). [4]

Industry Overview – Segmentation, Products and Services

Non-traditional mobile- and internet-based products and services are adopted increasingly in the region as total numbers of subscribers grows. Services like Mobile TV and IPTV gain ground in the market as consumers seek additional value-added services to complement their existing subscriptions. Other products, such as mobile banking, have seen less encouraging uptake as they enter the market. Industry analysts have speculated that conducting financial activities on mobile platforms is not culturally intuitive for consumers in the Middle East, giving reason for mobile banking’s failure to penetrate the regional market despite eager adoptions of other non-essential mobile services.[5]

Competitive Environment and Company Profiles

Some monopolies and duopolies still exist in the region, particularly in countries experiencing less growth in data demands and lower average income levels (such as Lebanon and Yemen). Some former monopoly markets, such as UAE and Qatar, have introduced new entrants in the latter part of the past decade. Due to the recent implementation of these changes in the competitive environment, most countries in the region have a very powerful incumbent.[6] Other more poorly regulated markets, notably Iraq’s market for internet, have a highly competitive atmosphere with as many as 16 licensed competitors.[7]

Research Conclusions for Satellite

The significance of these trends and developments in telecommunications in the Middle East for satellite operators is notable. Mobile and internet operators face the challenge of maintaining quality services while simultaneously upgrading their networks to cope with current and projected levels of data traffic volume. These telecommunications companies turn to satellite backhaul services in order to ensure that end consumers still receive network services when existing terrestrial networks are exceedingly stressed. How subscriber growth continues in the Middle East over the next decade will be of particular importance to satellite operators. Continued strong growth in both data demands and subscribers in the region will ensure that network operators continue to need satellite backhaul services. On the other hand, the stability of strong growth in ICT services in the Middle East is not certain. Already, more developed countries are closely nearing mobile and internet saturation levels (such as Bahrain and Oman),[8]meaning that in the future, revenue growth will not be driven solely by nominal growth in subscribers, but also by non-essential mobile and internet services (such as mobile banking, mobile TV and IPTV). Looking ahead, how satellite operators package their services in the Middle East telecommunications industry in the coming decade will be of increasing importance. As satellite aims to play a key role in providing the region with opportunities for growth and more efficient access to information and communications technologies, planning for strategic partnerships and offerings for this region will be critical in the years to come.

Telecommunications and International Development

Submitted to Professor Kathleen Day
University of Ottawa, May 11, 2012

Despite having the technological capability to bring most of the world’s population online, there remain technological, regulatory, financial and political barriers. Data published in the Millennium Development Goals Report 2011 show evidence of these challenges. Figure 2 (below) shows that internet penetration has remained low in LDCs compared to growth in developed and developing regions since 1998.[1] Thus, regardless of the ability of satellite and other new technologies to connect unconnected populations in LDCs, persistent low internet penetration suggests that other barriers exist.

Figure 2 Source: United Nations, 2011.

In developing and least developed regions despite regulatory and financial barriers to connectivity, internet and mobile subscriber growth is nonetheless accompanied by increasing volumes of data traffic. The challenges of this growth for telecommunications companies in the Middle East have already been discussed in terms of infrastructure in the previous section of this report. For developing and least developed countries, subscriber growth (and subsequently growth in connectivity) is limited due to the often poor and underdeveloped state of terrestrial communications infrastructure.[2] In anticipation of these limits, wealthier countries in the Middle East have begun updating existing networks to accommodate future increases in data traffic. However, technologies are not suitable for all regions equally. How these technologies work is thus important to a discussion of expanding connected populations. In the case study to follow, the technical capabilities of two competing forms of internet and mobile networks (WiMAX and LTE) is discussed with consideration for their uses in the developing world.

CASE STUDY: WIMAX VERSUS LTE TECHNOLOGY

WiMAX and LTE are 4G technology standards that compete to provide end consumers with an alternative technology through which they can consume data abundantly at high download speeds. These are among the handful of technologies that telecommunications companies rely on to serve customers. There are a few key differences between WiMAX and LTE, which make their capabilities and suitability vary by region and circumstance. WiMAX is a fixed-line internet technology. Working much like a modem does, WiMAX can provide internet services over a radius of many kilometres from a telecommunications tower. For instance, it can provide internet access to a city or region like a hotspot does for a city block.[3]

LTE, on the other hand, is a mobile technology, able to provide internet, data and voice services like a cellular network, with higher bandwidth capabilities than WiMAX. The offering of LTE versus WiMAX is comparable in that they both provide similar download speeds for small populations. LTE, however, is able to handle much higher traffic volume, and thus has much more capacity per user than WiMAX.[4]

The cost associated with these technologies differs vastly. WiMAX is significantly more cost-effective to roll-out then LTE in areas with low population density. Consequently, WiMAX technology is found more frequently in less developed regions with low investment capabilities and limited infrastructure, such as rural parts of Africa and Asia.[5] LTE, however, is under development in emerging economies where there is greater fiscal capacity to invest and higher-density areas. Wealthier countries in the Middle East region, such as Saudi Arabia and UAE, have invested in implementing LTE in order to cope with their projected data demands within the next decade.[6]

These differences between WiMAX and LTE point to a gap in development strategies for the developing world in terms of telecommunications. Although current technological capabilities can feasibly bring connectivity to the populations of developing and least developed countries via tailored solutions such as WiMAX and LTE, other barriers prevent telecommunications from expanding into these markets. The findings concerning the industry in the Middle East suggest that lack of investment is the most significant issue. Certainly for countries experiencing growth in traffic volume and challenges in infrastructure, attracting investment to update existing terrestrial infrastructure is critical. LDCs on the other hand are limited in that growth in telecommunications is low and investment is consequently scarce. In these cases, it is important that other development goals such as improved overall health and education are addressed in order to create an economic, political and social environment that fosters business growth.

There are also technological barriers that are less evident than the macroeconomic issues described above. Satellite, for example, faces challenges in telecommunications in developing and emerging markets. Although WiMAX with lower capacity to handle high amounts of traffic would rely more on satellite backhaul to ensure uninterrupted services, it also risks interfering with particular satellite frequencies.[7] Conflicting technical solutions pose significant issues for developing regions. As WiMAX and satellite are both viable ways to connect rural and remote regions with risk of interference, critical decisions concerning which technologies to invest in are left with national regulatory bodies. This web of issues and solutions thus involves diverse areas of expertise. The discussion here touches on only some, including technology, policy, politics and economics. The complexity of providing connectivity to the unconnected quickly becomes clear.

Nevertheless, the fiscal strength of the satellite industry in particular suggests that satellite remains a strong solution for broad-based global connectivity. As satellite is technologically capable of connecting 99% of the world’s population, it is reliant on progress in the remaining development goals to create the strong economic, social and political environment needed to spur demand and growth in the telecommunications markets of the developing world.

Defining Green Technology on the Web

Green Technology in the Private Sector

General Electric Company. (2011). Ecomagination. Retrieved November 24, 2011 from http://www.ecomagination.com/

Screenshot taken November 24, 2011

The Ecomagination website’s expansive provision of General Electric (GE) Company’s reports, press releases, showcase technologies and product portfolios make this site both impressively (and almost dauntingly) informative on current private sector approaches to the adoption and growth of green technologies.

Ecomagination, launched in 2005, is GE’s business strategy for addressing the global need for cleaner sources of energy, reduced greenhouse gas (GHG) emissions and reliable sources of clean water. The strategy’s global and multi-local outlook to seeking technological innovation outside of GE represents the Company’s open and collaborative technological approach towards climate change mitigation. The information available on this site, from the reports detailing GE’s technologically-driven mitigation progress to the showcase prototype technologies that may make a sustainable post-oil world possible, exemplify the realistic capability of the private sector to rapidly redirect resource consumption through its environmental technology research and development. It is important to realize, however, that climate change adaptation in terms of its risks and implications for GE (as opposed to climate change mitigation) is absent from the website’s overall discussion.

It is also interesting to note that, in a thorough read-through of the Ecomagination 2010 Annual Report (available under “Press Releases”), the influence of green technology’s many overarching challenges is present throughout. Despite political uncertainty and lack of supportive public policies, for example, GE states its commitment to continue investment and development in green technologies. It further emphasizes the necessity for green technologies to be efficient, cost-effective and reliable in an increasingly competitive global context. As well, the Company’s global and multi-local outlook is not overlooked from Ecomagination’s scope. An open and multi-national model for collaboration is one of three pillars to GE’s strategy, and is represented in their work with local-level groups and private enterprises in Asia and Latin America.

Although the Company indicates a commitment to addressing local needs in a multi-national outlook, further information on their commitments across the world, and particularly in the Global South, are scarce and difficult to find. Although there is summative information on GE’s activities in countries such as China and Brazil, this information is limited and vague. As a multi-national private company based in the United States, the American focus and pro-corporate bias is unmistakably clear. It is only further exemplified by its clear commitment to job growth in the U.S. and absent evaluation of weaknesses in GE’s operations. Though Ecomagination is nonetheless an informative window into the private sector’s approaches to green technology, its questionable degree of transparency and bias makes this source limited in its objectivity.

Green Technology in the Public Sector – Research

Harnessing the Wind’s Vibrations for Electricity is an article that discusses the work of Cornell University’s Vibro-Wind Research Group and their development of a much smaller-scale energy alternative to wind turbines. This alternative, called the Vibro-Wind prototype (or simply “Vibro-Wind”), is a standing array of foam oscillators that, when moved by gentle winds or breezes, convert their vibrations into stored electricity. The article illustrates the mechanics of piezoelectricity (a form of electricity that enables the transformation of mechanical energy into usable electric power), as well as the premise behind the prototype and its potential implications for the availability of alternative energy to city-dwelling consumers.

The article is featured on Discovery Communications’ child company TreeHugger, and written by one of its writers Kimberley Mok. TreeHugger, a media outlet, hopes to mainstream the discussion of sustainability through its website. Mok, an architecture designer and Cornell University alumni, contributes this article with a primarily promotional view of the Vibro-Wind prototype. Unfortunately, the article discusses many of the potential benefits of small-scale wind energy, with none of its potential weaknesses. The energy conversion efficiency, cost comparisons, and performance data are lacking in the article (most likely because this data is not yet available to the public), thus providing a notably incomprehensive view of the Vibro-Wind prototype. Despite this limitation, the article is a strong informant for the potential and capability of students and research institutions to develop innovative alternative energy solutions for cities. The article most importantly highlights the potential uses of Vibro-Wind and piezoelectricity, including their advantages for capturing wind power in densely populated urban areas with less social and political disruption than its turbine-alternative. Mok also offers further information on the potential for piezoelectricity by pointing to its other manifestations in equally innovative projects, from utilizing crowd energy to individuals’ human motion. Perhaps most impressively, the Vibro-Wind prototype has, since its debut on TreeHugger, captured a spot on the New York Time’s 10th Annual Year in Ideas (2010) and was created into an animated infomercial under the New York Time’s sponsorship.
