Well, just about everything needs energy. But there are a few transportation systems that use energy that is already available and not used for anything else. In this article, I want to show you three solutions that require no oil to be pumped, no coal to be burned, and no electricity to be generated.
Drought, drones and maglevs: These are the transportation news stories I found noteworthy in the last two weeks.
The transport sector is responsible for a large proportion of global greenhouse gas emissions. It is essential that it be converted to renewable energy. For cars, the transition to mainly battery-electric vehicles has begun. But for trucks, the technology of choice is not yet clear. Because they are much heavier than cars, they will also need larger batteries. Right now, there is a race between battery electric trucks, hydrogen trucks, and overhead catenary trucks. Yes, you read that right: Trucks with a catenary, like an electric train! How do they work and what are their chances in this competition? Read on to find out more.
This week I want to share with you some news articles from this week that I found particularly noteworthy.
Last week I wrote about how owning a car can be the most efficient mobility solution for an individual.
In that article, I argued that because of this fact, cities that want to reduce traffic caused by cars should try to change the equation for individuals, so that other options like walking or public transportation appear more efficient than driving.
However, there is another side to my argument: While a car is usually the most efficient transportation solution for an individual, it may also be the most efficient solution for society. This is because car owners take care of most of their own needs – they buy the car, they maintain it, they drive it. Society only has to provide the road. What are the consequences of this observation?
Owning a car is still a dream for many people around the world. Increasing car ownership brings many problems to cities and their inhabitants – noise, pollution, congestion, accidents and more. Communities and governments around the world are trying to find solutions to reduce these negative effects by reducing the number of cars or getting rid of them altogether. However, this goal seems to be elusive – for example, carsharing schemes have increased traffic instead of reducing the total number of cars in a city. In this article, I point out the fundamental problem that I believe lies at the heart of the failure to get rid of cars.
