Green ICT Innovations

Researchers and businesses are advancing innovative ideas with potential for mainstream Green ICT. These range from products and services available today to futuristic concepts for tomorrow. The latest looks at how the brain's energy efficiency is influencing the delivery of cloud services.

The brain as a model for low-energy computing

A New York Times article describes work at Google and Microsoft to deliver cloud services via neural networks - large collections of processors that constantly learn how to improve the performance of a task like speech recognition. The problem? "That requires enormous computing power, and if companies like Microsoft use standard-issue chips to do it, the process takes far too long because the chips cannot handle the load and too much electrical power is consumed." The solution? "...the leading internet companies are now training their neural networks with help from another type of chip called a graphics processing unit, or G.P.U. These low-power chips...were originally designed to render images for games and other software, and they worked hand-in-hand with the chip...at the center of a computer. G.P.U.s can process the math required by neural networks far more efficiently than C.P.U.s."

An inspiration for all this? "As [Gill Pratt of Toyota Research] sees it, machines that spread computations across vast numbers of tiny, low-power chips can operate more like the human brain, which efficiently uses the energy at its disposal. 'In the brain, energy efficiency is the key,' he said ..."

Update

The day after we posted the above, we saw another approach to thinking about neural networks and energy efficiency. Verne Global announced, "...DeepL has deployed its 5.1 petaFLOPS supercomputer in [Verne Global's Icelandic data center,] designed to support DeepL’s artificial intelligence (AI) driven, neural network translation service..." A Deep L executive is quoted, "...the abundance of low-cost renewable energy and free cooling will allow us to train DeepL's neural networks at lower cost and faster scalability..." (More on Verne Global and Green ICT.)

Current without resistance

The Australian Research Council's Centre of Excellence in Future Low-Energy Electronics Technologies (FLEET) is an international collaberation to address the challenge of ICT energy consumption. "FLEET will meet this challenge by realising new types of electronic conduction without resistance in solid-state systems at room temperature. These concepts will form the basis of new types of switching devices (transistors) with vastly lower energy consumption per computation than silicon CMOS. Electronic conduction without resistance will be realised in topological insulators that conduct only along their edges, and in semiconductors that support superflow of electrons strongly coupled to photons. These pathways are enabled by the new science of atomically thin materials."

'Dissipationless systems', 'atomically thin semiconductors', and 'non-equilibrium topological phenomena' will likely yield more futuristic applications than those described below, but this kind of advanced research is critical for game-changing breakthroughs in sustainable ICT technology. The FLEET site contains videos explaining these concepts.

FLEET also asserts, "The current technology, silicon complementary metal-oxide-semiconductor (CMOS) will stop becoming more efficient in the next decade as Moore’s law comes to an end."

Mobile base station designed for renewable power

Over 700 million people are covered by mobile networks, but live in areas without reliable electricity. Deployment of remote base stations powered by renewable energy is growing, but they most are still powered by dirty diesel generators.

The Development Impact Lab (DIL) at UC Berkeley has developed a village base station called the Community Cellular Network (CCN). "The CCN is a complete 'network-in-a-box', enabling local communities to both own and operate their own cellular systems. The network is designed for the world’s most remote communities and can be deployed by people with limited technical skills. At its core is a village base station, or cell phone tower. Each CCN is costs less than 1/10th the price of traditional cellular equipment, and its low power consumption enables it run solely on solar or micro-hydro power. It is also highly efficient, using less than 50W average power draw, which reduces infrastructure and operating costs. The network can provide kilometers of coverage to local communities."

Reusable electronics modules

Nascent Objects offers a potential approach to reducing e-waste by promoting a modular approach to electronics. The idea is specific capabilities could be upgraded without replacing the entire device. The company was recognized as a 2016 Sustainia 100 solution: "Nascent Objects provides people with the opportunity to design and reuse modular electronics, giving hardware a much longer shelf life."

Floating data centers

Nautilus Data Technologies claims to be "...the first company to successfully launch a waterborne floating data center prototype, pioneering a new standard for data center energy efficiency, environmental sustainability and global scalability. Nautilus Data Centers will dramatically reduce the cost of computing by providing the industry’s lowest power usage effectiveness (PUE)..." The company reports, "The first commercial Nautilus data center is currently under construction at California’s Mare Island Shipyard, where Nautilus successfully validated its first proof-of-concept prototype data center in 2015." These datacenters are designed to be docked at ports, not floating on the high sea like the wave-powered data center Google patented in 2009.

"One average size data center can consume enough water to supply 2,000 homes a year...Nautilus leverages the natural water below to cool the data centers, and all the water is recirculated safely back into the original body of water." Besides consuming new water, the company is targeting its facility to reduce energy consumption and carbon emissions by 30%, compared to an average 8mw data center.

Greener computer mouse

Germany's Faire Maus is an effort to create a socially and an environmentally sustainable (#3BL) computer peripheral using the 'Fair Trade' model. The producer, Nager IT, offers a detailed description of current green features and future goals. The Faire Maus is only available in Europe at this time.

Ebola tablet with unique energy features

The Hot Hardware site describes the effort to produce an "Ebola-proof" tablet to communicate patient data from inside containment facilities. "The Sony Xperia tablet comes with an extra protective shell, can withstand chlorine dousing as well as exposure to the high humidity and storms that are typical of life in West Africa. And it can even be used by workers wearing protective gloves."

We are especially interested in the tablet's energy features. "It is placed on a table to charge, quickly and wirelessly, and can transmit data to servers on the outside of the zone. This last aspect of the tablet may not seem the least bit impressive to Westerners, but is nonetheless considering the limited state of Internet access and infrastructure in the West Africa region. To illustrate, the server that receives the transmissions from the tablets — which is about the size of a postage stamp — runs on lithiumion batteries now, but during testing had to be connected to a motorcycle battery for its power. "

The tablet is a collaborative effort among Whitespell, Hack4Good, and Google in response to a challenge issued by Médecins Sans Frontières.

Computer using 100% recycled plastics & negative-carbon packaging

Dell announced a computer for sale in June 2014 that set an industry milestone, "Dell will be the first company in the IT industry to use UL-Environment certified closed-loop recycled plastic in a computer with the launch of the Dell OptiPlex 3030 All-in-One desktop...By reusing plastics already in circulation, Dell is cutting down on e-waste, saving resources and reducing carbon emissions by 11 percent compared with virgin plastics...Dell plans to use this closed-loop approach as a blueprint for reusing metals and other materials and to accelerate Dell’s goal of using 50 million pounds of recycled-content plastic and other sustainable materials in its products by 2020. "

Dell also announced that, ..."carbon-negative AirCarbon material from bio-tech start-up, Newlight Technologies....a plastic material made from air and greenhouse gases that would otherwise become part of the air...will launch this fall beginning with the packaging sleeves around new Dell Latitude series notebooks... Previous Dell packaging innovation includes bamboo and wheat straw that helped eliminate 20 million pounds of packaging and saved 18 million dollars. The new AirCarbon packaging, greener and less expensive to manufacture than oil-based plastic packaging. "

Wood-frame, award-winning, touch screen computer

iameco v.3 is a Windows-based, touch screen computer. The Irish company says, "Less than 360 kilograms CO2eq is produced over the full product life cycle....Almost all of the materials used in the computer are recyclable, including the wooden frame. Hazardous materials typically used in a computer manufacturing process have been reduced to a minimum for iameco and replaced with environmentally friendly alternatives. ...Our computers are designed to last about three times longer than average – up to 10 years. They are designed for lifetime extension (DfLE) and designed for disassebly (DfD)." The v.3 won a 2014 Sustainia 100 award. The company also says it, "...is the first computer of its kind to win the prestigious EU Eco Flower certification," but we are unable to provide a link due to the Eco Label (Eco Flower) dysfunctional web site.

The v.3 features a 15.6" screen. By way of comparison, an Apple's 15" MacBook Pro, a full-featured laptop, has a life-cycle footprint of 690 kg CO2e while Apple's 9.7" iPad Air has a footprint of 210 kg CO2e.

Sustainable Workstation for Remote Areas

The ICT needs of developing economies (ICT4D) often converge with Green ICT. The Inveneo High-Performance Computing Station "is a low-power desktop computer designed for use in rural and off-grid locations where processor speed is required but electrical supplies are limited or unreliable, like underserved clinics, schools, community centers, and microfinance offices. Computer components [are] integrated into a single compact unit, optimized for performance at minimal power usage." The unit features a 22-watt Intel Atom processor, mobile device technology that is increasingly finding its way into low-energy computing, and a 7-watt 15" LCD screen. The package features a 12VDC power input, so it can run off PV solar directly through a charge controller or via a solar-charged battery.

Energy efficiency is not the only trait ICT4D shares with Green ICT. 'Sweating assets' talking to extending our gear's lifecycle to reduce everything from embodied carbon to e-waste. This is particularly important in remote areas when maintenance is difficult. Inveneo notes that its station offers "...rugged hardware stands up to hot, dusty computing environments...has a very low Total Cost of Ownership (TCO) and is designed to be sustainable even in resource-constrained environments."

Charge Devices While Walking

The Wall Street Journal reports, "The explosion in electronic gear in the modern military, from radios and GPS equipment to night-vision goggles, means a typical soldier may carry a dozen devices and 70 batteries on a three-day patrol. That adds weight — 16 pounds or so — to already-overburdened warriors." A start-up funded in part by the Office of Naval Research (USA), Lightning Packs LLC, is trying to commercialize a backpack that can generate 15W-40W from a 50-pound load. (This is an example of energy harvesting for ICT.) As a Green ICT advocate, an outdoor enthusiast, and a university-research-to-commercial-product entrepreneur, I'll be watching how this progresses.

Boil Water to Charge a Device

The PowerPot® has a thermoelectric generator that converts heat into DC power. It is designed to sit atop of a small gas stove or other heat source and charge a USB device while the pot boils water. The company claims that the latest model, the PowerPot X, can deliver "...a full 10 watts of max output. Even under mediocre conditions, it produces 5 watts, giving you ample power for charging any device." Backpackers will note that a $149 pot/lip/cable package weighs 18 oz; a basic $16 aluminum pot/lid combo with 36% more capacity weighs 8 oz. The company invites buyers to donate to its Give A PowerPot program to distribute units to people who have mobile phones but who live in the off-grid areas of developing economies. (The image to the right is from a field trial in Ghana.) Fixed-base use, either in remote areas or in emergency situations, mitigates the weight issue and the donor program helps make the technology available to the less-affluent.



Tiles Made from CRT Glass

Fireclay Tile (CA-USA) successfully completed in December 2013 a Kickstarter campaign to convert CRT glass to tiles. The funds are for the necessary molds; the CRT glass is from ECS Refining. Recycled CRT glass had been used to made new CRTs, but that market has dried up leaving an estimated 660 million pounds of CRT glass* in storage in the United States. Here's the Kickstarter video:



3-D Printer from Recycled E-Waste

Crowdfunding site Ulule features a 3-D printer made from recycled e-waste targeted to cost less than $100. The W.AFATE project is the brainchild of Togolese entrepreneur Afate Gnikou.



Urban Solar Charge Stations for E-Devices

We've covered many examples of PV solar used for ICT in remote areas developing economies, but it can be applied everywhere. The New York Times reports in June 2013 that telecom service provider AT&T's "…25 solar-powered charging stations will sprout in parks, beaches and other outdoor spaces in [New York City's] five boroughs, part of a pilot project from the wireless provider in partnership with the city. The stations — 12.5-foot steel poles with three petal-shaped solar panels fanning out on top — can accommodate up to six devices at a time regardless of wireless carrier, with dedicated ports for iPhones, Androids, BlackBerrys and standard USB charging cables…If successful, AT&T could expand to other cities. The project will cost $300,000 to $500,000…Three 15-watt panels and a 168-watt-hour lithium ion battery pack can keep the stations operating through the night or five days without sunshine. The stations will allow a user to fill a smartphone in two hours, or grab a 30 percent charge in 30 minutes." We've noted in other posts the environmental problems caused by diesel-powered telecom and there is a tie-in here. "The spark for the project came after Hurricane Sandy, when AT&T supplied diesel generators and cell towers on wheels to hard-hit neighborhoods…"

PC Housing Made From Cardboard

Recompute's family of PCs are housed in corrugated cardboard cases and built to the company's philosophy of Full Life Cycle Design. Interesting insight into materials: "The ignition point of cardboard is very high, higher than most of the plastics used in traditional computer hardware design. Recompute cases have been tested safe to over 400F/200C. Most of us don't think anything of putting a cardboard pizza box in the oven, or boiling hot coffee in a paper cup, yet the internal components never reach a temperature higher than an oven or boiling liquid."

Novel Design for a Personal E-Device

Wandular is a 2025 concept device from Sony Europe's FutureScapes initiative made of wood, recycled steel, and high-tech components.

"Wandular is a multi-purpose, modular device that grows with the user over a lifetime, generating a similar sort of affection and sense of personal connection as a favourite watch. A cloud-based, thin client modular approach enables a long product life span, whilst ensuring the user enjoys the latest software and hardware upgrades.
Modular add-ons will allow devices to be physically upgraded with everything from projectors to motion sensors and energy generation modules. This means the device can be personalised and its lifespan extended. Local 3D printing of modules using recyclable materials could satisfy users’ thirst for novelty and customization whilst minimising the environmental footprint. This will also enable a closed loop system for adding new hardware to the device.
Integrating more emotionally engaging design elements provides a stronger connection between the user and the physical object, making it appealing over a longer time period."
