Reinventing the Wheelchair

Reading Scientific American this morning I spied the innovation that won their annual World Changing Ideas Video Contest: the Leveraged Freedom Chair designed by MIT Mobility Lab.

It's a three-wheeled human-powered wheelchair that goes faster than normal and also navigates difficult terrain—rutted roads, cobblestones, trash-strewn slums. The genius resides in the vertical hand levers: Users simply grab higher or lower depending on how much torque or speed they need. It's like being able to change gears.

The drivetrain consists of common bicycle parts and so is "manufacturable and repairable anywhere in the developing world," according to MIT. Sometimes low-tech solutions are the most appropriate.

Reclaiming Public Streets as Livable Space

Transportation Alternatives Executive Director Paul Steely White spoke at TEDxEast about ongoing campaigns to reclaim urban commons from the automobile. Cities are built for human contact and interaction, he said, which is thwarted when everyone sits behind a windshield. Streets that focus on the automobile also run counter to the density that makes cities interesting and efficient. "We are squandering the most valuable real estate in the world giving this public asset to the lowest density mode of transportation," said White.

The mandate for rearranging our urban landscape becomes clear when we grasp the global trends in population and urbanization: "Here in New York the streets comprise about one-fourth of the city's total land area, 80 percent of our open space. What happens in the space between buildings in the next 20 years is going to determine to a large degree how much carbon we emit, what our quality of life is, how often we talk to our neighbors and engage in civic discussion, how happy we are even."

Send A Colleague to Copenhagen

I won't be attending the Copenhagen climate conference but my colleague David Kroodsma still has a shot to do so if he wins the Huffington Post contest to send a citizen journalist (You can vote for him here). David is a writer, climate-energy expert, and bicycle adventurer with degrees in physics and climate science. He and I met last year on the Climate Ride while we were traveling to Washington to lobby for clean energy. Prior to that, David bicycled across North and South America to raise awareness of global warming and he has since documented his journey in a forthcoming book.

I spoke with David recently about the city of Copenhagen and how one-third of commuters there use bicycles. Below is an excerpt from his book where he talks about the choice world cities face: They can either copy Copenhagen, or they can copy American cities such as Los Angeles. The excerpt is from his chapter on Colombia. David visited Bogota and saw how investments in public transportation and bicycle infrastructure have helped to reduce carbon pollution and make the city a more pleasant place to live.

Something else remarkable has happened in Colombia over the past decade: the country has reduced its carbon dioxide pollution. Some of this reduction has been because of an increase in hydroelectric power—eighty percent of the country's electricity comes from dams—and a decrease in coal-fired power. But the Transmilenio [the public transit system] and bikeways have also had a serious effect, perhaps decreasing Bogotá's pollution by over half a million tons of carbon dioxide a year and cutting Bogotá's total pollution by a few percent. Car use in Bogotá has dropped significantly, and nearly twenty percent of daily trips are via the Transmilenio, an efficient service that didn't even exist a decade earlier. Bogotá shows that reducing pollution often has ancillary benefits. The city didn't set out to reduce pollution. The city set out to make itself more livable, and consequently reduced fossil fuel use.

If cities in the developing world decide to copy Bogotá, how big of a difference would it make? In the next thirty years, almost all growth in greenhouse gas pollution is expected to come from developing nations such as Colombia—nations where living standards are rising rapidly. Cities in these countries are growing rapidly, and decisions made today will decide the transportation infrastructure for decades to come.

A city like Bogotá could look to U.S. cities like Los Angeles where the majority of commuters drive, or they could look to European cities such as Copenhagen where transit is evenly divided between personal automobiles, public transportation, and bicycles. Whereas the average citizen of Los Angeles produces about five tons of carbon dioxide per person through transportation, the average citizen of Copenhagen is responsible for less than one and a half tons per person from transportation.

Half of the world's population now lives in urban areas, and the difference between these cities copying the transit system of Los Angeles versus copying the transit system of Copenhagen is thus a difference of about 10 billion tons of carbon dioxide. Given that global carbon dioxide pollution from fossil fuels is roughly 30 billion tons today, the difference between a world of Los Angeleses and Copenhagens is dramatic.

Here is David's video for the HuffPo Hopenhagen contest. Don't forget to vote:

Resilient Cities

I just attended a hopeful presentation by Australian urbanist Peter Newman on his concept of Resilient Cities. We're at the toxic intersection of several trends: peak oil, global warming, and scattered, car-dependent residential growth fueled lately by subprime mortgages. According to data he presented from the UK Industry Taskforce on Peak Oil and Energy (Nov. 2008), "the underlying trend in the price of oil is 6 percent growth per year." Combine this with the IEA's recent World Energy Outlook that says the "natural annual rate of [oil output] decline is 9.1 percent from 2009" and it becomes pretty obvious that massive changes in our energy and transportation infrastructure and technology are around the bend.

Newman lists four courses the modern city may take:

Collapse: It's happened before and could happen again. Newman cited the ancient examples of Ephesus and Babylon, and while total abandonment seems less likely in today's world, a tour through Rust Belt American cities such as Gary, Indiana, should suffice as a warning of potential decay.

Ruralization: Food production moves to the cities somewhat, as happened in Havana when the Soviet Union cut off energy supplies. Total ruralization with every apartment complex growing its own food seems unlikely because it would disrupt the whole logic of the city as an opportunity factory.

Division: Wealthy eco-enclaves will coexist with and be surrounded by Mad Max suburbs. This is a highly probable outcome if market forces play out sans smart urban and regional planning. This pattern is already prominent in the developing world where gated communities abut slums.

Resilience: Combining all the dream elements of renewable energy, distributed systems, smart grids, carbon neutrality, and sustainable transport, resilient cities are basically environmental utopias--only impossible if viewed as overnight projects. Alone among these four types, resilient cities are founded on hope not fear, though division, ruralization, and collapsing neighborhoods may all accompany the transition to resilience.

Newman focused today on the fact that land use follows transport, thus illustrating the importance of public transit-oriented development. His sense is that the stimulus and transportation initiatives of the Obama era must move dollars from freeway construction to sustainable options. Spending $100 million per mile on a freeway, as Houston did, seems like Stone Age economics at this point.

I suggested to him that transition to high gas mileage electric vehicles (100+ mpg) might forestall investment in public transit, but he seemed optimistic that, given the bigger picture of climate change pressuring the economy, plug-in cars and vehicle-to-grid technologies will prove a win-win situation. Let's hope he's right.

Policy Innovations on the Road

Policy Innovations staff is traveling this month on a couple projects related to climate change.

GPI Director Devin Stewart is leading a Carnegie Council delegation to Beijing to lay groundwork for China-Japan-U.S. dialogues on ethics, energy, climate change, and faculty development.

Devin will be accompanied by Joshua Eisenman, an Asia Studies Fellow at the American Foreign Policy Council and Ph.D. candidate at UCLA; Jonathan Gage, a Carnegie Council trustee and principal of Booz & Company, where he also publishes its magazine strategy+business; Harry Harding, University Professor of International Affairs at the George Washington University; and Alex Westlake, managing director of ClearWorld Energy (based in Beijing).

Stewart and Eisenman are coordinating the itinerary with the China Reform Forum in Beijing. Institutions to be visited include Peking University, Renmin University, Chinese Academy of Social Sciences, and the China Institutes of Contemporary International Relations. The trip was made possible by generous support from ClearWorld Energy.

Meanwhile, Policy Innovations Managing Editor Evan O'Neil is literally hitting the road. He's biking in a peloton of 120 riders from New York to D.C. to meet with Congressional staff to discuss transportation and climate policy. To learn more about the story behind Evan's Climate Ride, take a look at the sponsorship page our web designer Graham Slick put together for him, or at Evan's new blog Inside Climate.
