Infrastructure That Cleans the Air

Barcelona is going to build a road bridge which may be the cleanest bridge yet. Of course it’ll have pedestrian walks and bike paths, however, what makes the bridge really noteworthy is that it will clean the air.

Concrete is notoriously energy-intensive to create so any carbon offset is beneficial. The Barcelona bridge will make use of photocatalytic concrete.

But the real prize of this thing is its basic building material, photocatalytic concrete. The principal of photocatylitics is that ultraviolet light naturally breaks down dirt, both natural and synthetic. It’s that old adage about sunlight being the best disinfectant. Photocatalytic concrete is used with titanium dioxide, which helps accelerate the natural UV-breakdown process, turning the pollution into carbon dioxide, and oxygen and substances that actually belong in the atmosphere.

The actual process has to do with semiconductors and electrons and other things that you may or may not care to read about. (At any rate, the Concrete Society of the United Kingdom does a better job of explaining it.)

An air-cleaning bridge makes for a neat news story and a sci-fi-ish novelty that environmentalists can blog about. But the important point is that Barcelona has taken a piece of infrastructure that exists solely to accommodate car culture, and re-invented it to partially offset the effects of car pollution.

Bike Lanes Improve Cities Aesthetically and Economically

There is a strong and powerful myth in North America that car drivers spend more and will always require parking. That is a myth. It turns out that nearly every study done on bike lanes as proven that cyclists are the transportation class cities should cater to because drivers don’t need all those useless parking spaces and drivers aren’t richer than others. (They have to waste all their money on gas and repairs anyway.)

Transportation Alternatives

A neighborhood survey of 420 people on First and Second avenues in Manhattan’s East Village, home to protected bike lanes, found that aggregate spending by non-drivers accounted for 95 percent of all retail spending in the area. That’s not too surprising in New York, given the great transit infrastructure, but the figures remain impressive. Cyclists spent about $163 per week on average, compared to $143 among drivers.

Seville is Spain’s Cycling Gem

It’s well known that the future of urban design and transportation will support the mass use of bicycles. Still, some cities are slow to catch on to this. In Spain where cycling is not nearly as popular in colder northern parts of Europe the city of Seville is leading the charge into the future.

How Seville became such a great cycling city is a far out tale:

“As soon as the building work was finishing and the fences were removed the cyclists just came. The head of the building team, who’d been very sceptical about the process, called me and said, ‘Where have all those cyclists come from?’ That’s when I knew for sure it was going to work. The came from all over the city.”
…
The net result is not Dutch or Danish levels of cycling, but nonetheless impressive. The average number of bikes used daily in the city rose from just over 6,000 to more than 70,000. The last audit, about a year ago, found 6% of all trips were made by bike, rising to 9% for non-commuter journeys.

Paris to Spend €100m on Bike Lanes While Reducing Car Traffic

Paris has had a tough time with traffic and pollution in the city due to the number of cars. They have launched many environmentally friendly intitaves to curb the use of cars while making alternative transit solutions to cars more appealing. It’s working and is already inspiring other cities to follow suit. Still, traffic in France’s capital is still quite bad so the mayor as launched a new program investing €100m on new bike lanes!

“I want diesel cars out of Paris by 2020 and, if possible, beyond the peripherique,” said the mayor, referring to the city’s constantly choked ring road.

“Today, 60 per cent of Parisians don’t have their own car, whereas in 2011, it was 40 per cent. It’s moving quickly,” she said.

In proposing a raft of anti-pollution measures, Ms Hidalgo is building on the efforts of her predecessor and mentor, the former Paris mayor Bertrand Delanoe.

He championed bike and car rental schemes, expanded bus and bicycle lanes, and reduced speed limits, as he sought to wean Parisians off cars in a bid to make the city more liveable.

Toyota Releases 5,680 Patents for Fuel Cell Technology

Toyota has followed Tesla’s strategy of giving their patented technology away for free. The patent system is so obviously broken so it’s nice to see these large corporations just letting their patents go. Ultimately, this means that other car companies can now use fuel saving technology (or whatever Toyota has invented). Hopefully we will see less environmentally damaging vehicles on the road.

Perhaps the most newsworthy announcement came when Toyota said it would make all of its 5,680 patents related to fuel cell technology available, royalty-free, to other companies manufacturing and selling both fuel-cell vehicles and hydrogen refueling stations. The idea is to drive more innovation in this somewhat nascent sector of the automobile industry.

“It’s obvious that there can be a higher societal value in openly sharing our IP,” Carter said. “By eliminating the traditional corporate boundaries, we can speed the metabolism of everyone’s research and move into a future of mobility quicker, more effectively, and more economically. Indeed, I believe that today marks a turning point in automotive history.”
