Active Transportation 10x More Cost Effective Than Passive Transportation

- Adam Clare

Want a better city but are limited by money? You should invest in active transportation first and foremost. Yet another study has shown that providing spaces for pedestrians and cyclists are a way better investment to improve urban wellbeing than leaving space to metal boxes on wheels. This most recent study comes from New Zealand where they are striving to make cities sustainable and healthy. Some cities try to improve the health and wellbeing of people by asking car owners to “share the road” or “not to murder non-drivers” in safety ads. It turns out the better thing to do is provide physical space for people to enjoy life. Let’s hope a people-first approach is adopted everywhere.

That’s not all. “The study demonstrates that the ‘benefit-to-cost’ ratio of the investment made by two city councils together with the New Zealand Transport Agency is around ten to one,” he says. “The study provides hard evidence of the benefits of investing in walking and cycling infrastructure and educational programmes, which comfortably exceed the costs. This is particularly useful at a time when the government is finalising its policy statement on land transport.”

So what will our cities look like five years from now? Great question. But it seems planners and various officials would do well to consider the benefits of cycleways and walkways – including from a financial standpoint.

Mobile Pollution Boxes Need to Pay to Enter Manhattan

Cars take up a lot of space in urban centres and deprive non-car owners of previous real estate and a clean environment. Yet, for years we have let car drivers occupy our cities with their large metal boxes which impeded the freedom and mobility of others. Back in 2003 London put in place the first congestion charge for their downtown and since then many cities around the world have followed. However, in car brain North America the idea never took off. Until now. New York City will be implementing a congestion charge for Manhattan starting this spring.

Experts see the measure as a first step in the right direction. They believe the toll will help fund the city’s ailing subways and buses, and make the streets of Manhattan a friendlier place. It is also seen as an opportunity to put an end to the car culture in a city — perhaps the only one in the United States — that is perfectly accessible by public transportation, with the exception of isolated peripheral areas. Indeed, for this reason, some have said that the measure is not ambitious enough, arguing that it should apply to the five counties of New York.

“You have to start somewhere, and this is a great start,” says Howard Yarus, of the District 7 transportation committee. The group he represents proposed a plan in 2019 to eliminate free street parking, an unthinkable change for the urban landscape. “Until now, if I took my car, which pollutes the environment, to go downtown I didn’t pay anything, not even when parking. But if I went by public transportation, it cost me $2.90 [for a subway or bus ticket]. As a public policy, that seems terrible to me.”

How Heat Pumps Work

- Adam Clare

Despite the climate crisis some places (like Canada) are still building houses with fossil fuel based heating systems, and this needs to change. Gas companies and their planet-killing kin have used regulatory capture to ensure their desire to change the climate continues. However, their best efforts to force customers to use dead dino juice people are turning away from old style furnace for new high tech heat pumps.

Heat pumps sound like magic since they somehow extract heat from cold winter air. Thankfully, the Guardian has put together a nice visualization of how heat pumps work. The gif above is not from their english language site.

Whereas gas boilers burn gas to produce heat, heat pumps do something more complicated. Sometimes described as working like a “fridge in reverse”, they use a mixture of evaporation and condensation to transfer heat from outside to inside a building. In a cold winter, it can be hard to understand how these devices work.

Engineered Stone Banned Down Under

If you don’t work in one of the building trades then you might not know about engineered stone, but you have definitely seen it and probably touched it. It’s a type of stone made of crushed silica that is pressed together to make a new, and equally durable, stone (it’s like plywood made of stone). Many new builds use this type of modern manufactured stone for countertops and decorative surfaces. Australia has found that people working on this type of stone tend to develop health issues that can be life-ending, so the country has decided to ban the stone to protect those in the industry. This is a good thing to see and hopefully other countries will copy Australia’s new policy.

Trade unions, health organisations and personal injury law firms have all welcomed the ban, saying it will save lives.

“Engineered stone is a fashion product that is killing the workers who make it,” Australian Council of Trade Unions assistant secretary Liam O’Brien said.

“With alternatives readily available, why are we risking the lives of tradies for a fashionable finish in our kitchens?”

Dr Hoy said broader change was needed to make sure a similar crisis did not happen again.

“We can’t be waiting until people develop disease and they die from conditions related to work before we start acting,” he said.

“We really need to change the ways to identify problems at work, and act before people become sick.”

Solar Retaining Wall Goes Live in Switzerland

It might seem odd to put solar panels on the side of walls in a region with mountains, but that’s exactly what’s happening in Switzerland. One of the cantons in the country is looking to be powered by at least 40% renewables by 2035 (which is quite achievable); with terrain being scarce it’s hard to place large solar installations. However, retaining walls in some areas get a lot of sunlight depending on their orientations (south facing would generate more for example) and with geography like Switzerland’s there are a lot of retaining walls. The cantons of Appenzell Ausserhoden’s first installation generations 325kW which is the equivalent of 52 Swiss households.

The PV system was anchored on and in the masonry using an adhesive technique. An anchoring depth of a maximum of 90 mm could not be exceeded so that the retaining wall would not be adversely affected.

Due to the close proximity to the asphalt, the solar panels’ components are subject to exceptional corrosion requirements and are anodized for protection. Indirect components are made of aluminum – only the screw anchors are made of stainless steel.
