Energy

Despite growing smarter, the U.S. electric grid is expected to become more vulnerable and a prime target for a cyber attacks, according to a new report from the MIT Energy Initiative. The report, “The Future of the Electric Grid,” was published on Dec. 5 and cites weaknesses in oversight, processes, new communication devices, and the grid’s existing physical environment.

The study, led by MIT professors John Kassakian and Richard Schmalensee, focuses on the electric grid’s challenges over the next 20 years, including safeguarding the existing power structure, the rising prices in fossil fuels, and in the potential influx of renewable energy sources. The 268-page report also calls for the designation of a single federal agency to combat cyber attacks. President Barack Obama and his administration have advocated for the Department of Homeland Security to take the lead; other members of Congress would prefer the Department of Energy or the Federal Energy Regulatory Commission.

From The Future of the Electric Grid:

“This lack of a single operational entity with responsibility for grid cyber-security preparedness as well as response and recovery creates a security vulnerability in a highly interconnected electric power system comprising generation, transmission, and distribution.”

The report criticizes the current kilowatt/hour pricing system and concludes that the while the power grid is adequate for meeting today’s power needs, it will have trouble integrating alternative power sources like wind and solar. It also acknowledges that a cyber-attack will eventually succeed, and an investment of about $3.7 billion is needed to adequately secure the grid from attack.

From the report:

“Perfect protection from cyber-attacks is not possible. It is thus important for the involved government agencies, working with the private sector in a coordinated fashion, to support the research necessary to develop best practices for response to and recovery from cyber-attacks on transmission and distribution systems, so that such practices can be widely deployed.”

“The Future of the Electric Grid” is the sixth in the MIT Energy Initiative’s future-focused series, which has also studied natural gas, nuclear fuel, and transportation. For more information, view the report or watch a video discussing the report’s findings.

In many communication systems, data is transmitted via light beams through optical fibers. This transmission can be burdensome and relatively slow since once the optical signal arrives at its destination, it must be converted to electronic form, processed through electronic circuits, and finally converted back to light. MIT researchers have created a solution for this multi-tasked process, developing a new device that eliminates the need for conversion of optical to electronic signals.

From MIT News:

This technology could greatly boost the speed of data-transmission systems, for two reasons: First, light travels much faster than electrons. Second, while wires can only carry a single electronic data stream, optical computing enables multiple beams of light, carrying separate streams of data, to pass through a single optical fiber or circuit without interference. “This may be the next generation in terms of speed” for communications systems, (Toyota Professor of Materials Science Caroline) Ross says.

Ross, working in a group that includes, Thomas Lord Professor of Materials Science and Engineering Lionel Kimerling, Lei Bi ’11, and Juejun Hu PhD ’09, have developed what Ross calls a “diode for light” described in the Nov. 13 issue of Nature Photonics. Similar to an electronic diode, the device allows light to flow in one direction, but blocks it from returning in the other direction.

Garnet

Researchers used a form of a transparent, magnetic material called garnet, which is commonly used in jewelry but inherently transmits light differently in one direction than in another. The material covers one half of a loop connected to a light-transmitting channel on the chip.  The entire system can be created using standard microchip manufacturing machinery, making it much easier to commercialize than a system based on different materials.

What do you think? Could these advances replace the way fiber optic cables carry phone, TV and Internet signals? Let us know in the comments below or on Facebook.

Meet Zoe. She’s over six feet tall, about five feet wide, and spends all of her time near the stairs in the first floor of W20. She’s also MIT’s newest–and smartest–recycling machine. Part of a pilot program sponsored by MIT’s Facilities Department, Zoe is a sort of “reverse vending machine” that aims to make recycling easier, cleaner, and more efficient.

Created by Greenbean Recycling, a Somerville-based startup that was a 2010 MassChallenge finalist, the machine allows students to use their phone number as a login and tabulates their real-time energy savings impact. Utilizing an energy-efficient sorting process, it makes retrieving bottle deposits an instant process by electronically depositing refunds into a student’s TechCash or PayPal account, or it can be donated to a charity or MIT education program.

From CNN’s What’sNext blog:

A bar-code reader in the machine counts the number of cans, bottles, and the like that the person has dropped off—and then uploads that data to Greenbean’s website.

Recyclers can track their progress online and even engage in competitions with fellow students.

Competitions between fraternities at MIT have been particularly fruitful, [CEO Shanker Sahai] said, with the houses trying to compete against each other to get the top spot on an online recycling leaderboard.

Zoe keeps statistics in real time with info available at gbrecycle.com.

Since the end of July, MIT has recycled 15,024 containers to date, saving 2779 kilowatts of energy. Among the MIT community, the Facility Department’s John Hames has dominated the competition with 1,505 recycled items. Zoe-like machines are planned for Tufts, Northeastern, Brandeis, and Holy Cross during the next semester, allowing the colleges to compete against each other for eco-bragging rights and, eventually, sponsored prizes like sports tickets and gift cards.

Camping Day 4 near the Tropic of Capricorn landmark and Durham University.

“…After a shredded tyre (a quick turnaround thanks to our awesome tyre crew) we realized we were suffering a problem with our array….”

Day 2, Oct. 17

“…Our newly constructed battery pack (thanks UMich!!!) has a smaller capacity due to a lack of battery protection system circuitry, so we depleted most of it yesterday….[and] Nature was not on our side today…”

Day 3, Oct. 18

“…Once again, nature put up a tough fight. There were some major fires to the south throwing up large smoke clouds—this led to a huge decrease in array power…”

Day 4, Oct. 19

“….We upped our speed to 60-70 kph, finally allowing Chopper to strut its stuff….One terrifying moment was when we were run off the road by an oversize load trucking the other way…

Fracking is back in the headlines today after a federally-appointed natural gas subcommittee–convened by Energy Secretary Steven Chu and headed by MIT professor John Deutch ’61 PhD ’66–recommended increased oversight and greater public disclosure of the environmental effects of fracking, the controversial process in which water and additives are injected underground at high pressure to break apart geologic formations to release gas.

Environmental groups and some politicians have argued that fracking could contaminate water tables, but energy industry officials have repeatedly insisted that the practice is safe.

In an interview with the Financial Times, panel head Deutch said, “Our report is a compromise, and in that sense it will make nobody happy. This report is the only balanced discussion that I’ve seen of the shale gas industry.” Deutch’s involvement with the panel has been criticized due to the fact that he sits on the board of directors of two energy-related companies.

Four main concerns were highlighted in the panel’s draft report:

1. Possible water pollution from chemicals used in fracking and from methane gas releaed by the process

2. Air pollution from methane and equipment emissions used in gas production

3. Potential disruption to communities

4. Acumulative adverse effects on their ecology.

Public comments on the draft report will be accepted for the next week, before the final version is submitted to Chu and President Obama.

Read the draft, submit comments, and let us know what you think on our Facebook page.

A paper solar cell connected to a voltmeter demonstrates its output (26 V). Credit: Gleason Lab

Last year MIT scientists printed solar cells on paper, and now they’ve taken that research and made it more inexpensive and versatile. The current generation of cells can be printed on any ordinary uncoated paper, cloth, or plastic and folded hundreds of times. Using oxidative chemical vapor deposition to vapor-print electrodes, the printed solar cells produce less than 50 V, enough to power small devices.

The new technology is reported in a paper in the journal Advanced Materials, which was published a few days ago. Karen Gleason ’82, SM ’82, the Alexander and I. Michael Kasser Professor of Chemical Engineering; Professor of Electrical Engineering Vladimir Bulović; graduate student Miles Barr; and six other students and postdocs co-authored the paper.

Watch the video below, courtesy of the Gleason Lab, to see the solar cells dynamically folded and unfolded while the voltage is measured on a voltmeter. Learn more about the project.

MIT Faculty Forum Online logo

This Faculty Forum Online event took place April 27, 2011. Debate the topic in the comments. Also view the first webcast, about collective bargaining.

Update (4/27/2011): MIT releases “The Future of the Nuclear Fuel Cycle” report, which indicates that storage for spent nuclear fuel is more crucial than ever.

Recent events in Japan have shaken public confidence in the safety of nuclear power plants. Although the health consequences have so far been small, the Fukushima accident has rekindled fears of radiation around the globe and has renewed the discussion on the risks and costs of nuclear power. This puts into question the future of an industry that had been seen as one of the keys to avoiding the long-term threat of global climate change as well as nearer-term conflicts over scarce fossil-fuel resources.

Question: Why do people who say they care about the environment sometimes act as though they don’t when it comes to a specific change?

Reporter Elisabeth Rosenthal couldn’t help but ask that after she thought about the slew of environmental initiatives she’d covered in Europe—high-speed rail lines in Spain, urban congestion charging in Stockholm, bike-sharing programs in dozens of cities. And yet, she noted in her New York Times blog post, similar projects have been extremely contentious in the United States. Note the Cape Wind controversy in Massachusetts and the bike lane lawsuit in Brooklyn.

We at Slice posed Rosenthal’s question to three MIT alumni: a policy fellow from Oakland, a VP of sustainability in Chicago, and a foreign service officer in D.C.. Here’s what they said:

Ruth Miller ’07
Policy Fellow, Walk Oakland Bike Oakland

I think a lot of this apparent dissonance comes down to the feeling of “us” versus “them” within the broad “liberal” labels. Not every “environmentalist” can picture themselves on a bike. Maybe they see “cyclists” as old, white men in spandex with clicky shoes riding $1,000 bikes. Or maybe to them, “cyclists” are aggressive hipsters on fixies. Well-intentioned, “left-leaning” neighbors can feel that a bicycle lane will make it more difficult for “us” to get around while bringing “them” into the neighborhood.

One of the challenges for bicycle advocates is to change the image of the average person on a bicycle. Biking should be a safe, accessible, and fun mode of everyday transportation for everyone from 8 to 80 years old. As so few US cities have the infrastructure to make this a reality, even the greenest people can understandably feel excluded.

As advocates, we also need to diversify our reasons to support things like bicycling, recycling, and transit-oriented development. They’re more than just green and healthy: they’re also cost-effective. Bike lanes create more jobs per mile than highways at a tiny fraction of the cost. Many of these economic arguments appeal to “conservatives” – even George W. Bush was an avid cyclist while in office.

The old “liberal” versus “conservative” dichotomy just doesn’t apply here – it’s a different “us” and a different “them.”

As consumers, we are all varying shades of green.  And we generally have the choice to be deep green where it suits us.  So thrift-store shopping and hyper recycling may be paired with driving versus public transiting our children from school.  For many of us who like to think of ourselves as deeper green, that balance between personal activism and convenience are part of how we manage our environmental conscious.

While green for the good of the commons, and for the good of an ethereal climate future, sits on that same shaded continuum, it often adds complexity by removing choice. The paradox is, of course that, we need deep green good-for-our-future solutions, like bike-centric streets, competitive alternative energy and communities dense enough to support public transit, to mitigate and adapt to climate change, which will affect us all depending on where we live on the globe or in the topography of our cities.

Like any sudden change, bike lanes, wind turbines and mass transit that relatively suddenly become a part of my every day will become more welcome, even celebrated, as influential community leaders actively champion them; catastrophic events  illustrate their value;  and the turn of generations shifts perception of garishly new to an anticipated comfort.  In the meantime, perhaps claiming to having done a green thing first, (as long as someone else has done them first before us), is a convenient way to remind us of how commonplace and pragmatic these unchosen deep green elements of our surroundings are– changing the tenor from a community change thrust upon me to a choice that I’ve made based on someone else’s good judgment.

Visiting my suburban hometown after living in cities for several years, I was shocked at the new McMansions with solar panels.  Several dynamics were at play here.  First, there were two (and only two) of these renewable systems on houses standing next to each other. This demonstrated the social competition and personal one-upmanship that some behavioral economists are trying to exploit to “green” communities.  Second, these photovoltaic systems were located in New Jersey, a state that doesn’t get as much sunlight as the Southwest, but a place that has experienced explosive growth in solar electricity because of the personal benefits that local government subsidies provide.

More importantly, the calculus of installing solar panels on large suburban housing demonstrates the large cultural education and reformation that would be required to make real impacts on energy consumption.  A suburban household certainly uses more energy on heating, cooling and transportation than a city dweller would who mostly rides public transportation and lives in a more modest house.  Conspicuous, visible efforts like expensive photovoltaic systems are easier decisions than wholesale lifestyle changes.  This is especially true when such changes are not voluntary, such as a bike lane on your already congested road to work.

Ganson starts the ball rolling.

Ganson starts the ball rolling.

Glee in young eyes, excitement in adult faces heralded the start of the 2010 Friday After Thanksgiving (F.A.T.) Chain Reaction, held in Rockwell Cage Gymnasion at MIT—26 minutes of plunk, ding, plop as a ball wended through contraption after contraption.

This year, 1,683 people turned out to build, position, and then watch artist and renowned chain-reaction creator Arthur Ganson lead one of the MIT Museum’s most popular annual events. You can watch the 26-minute video now.

How does it work? Teams from all over the country bring a link, which is then connected to another link and it becomes one giant contraption, set off at the magic moment by Ganson. Engineering principles, laws about motion and energy, and other sciences guide  the ball’s dance.

Like this year’s video? You can watch past F.A.T. Friday videos starting with 2006.

In New York during the holidays? Stop by the Cooper Hewett National Design Museum for a close up encounter with the MIT CityCar, the brainchild of the late Media Lab director William Mitchell. The SmartCar is featured in the Mobility section of Why Design Now? the National Design Triennial (also accessible online for the rest of us).

The CityCar, conceived by the Smart Cities group, is a stackable, two-passenger electric vehicle designed for urban dwellers who can stop by a local charging station, swipe a card, and drive off in a charged up vehicle. Returned vehicles are stacked and recharged. The critical component of the car is an omni-directional robot wheel that contains an electric motor, suspension, steering, and braking.

Another MIT Media Lab project, One Laptop Per Child (OLPC), was honored for its second generation XOXO prototype, which consists of two touch screens that can act like a laptop or a book.

Second generation One Laptop Per  Child.
