There’s much talk about a coming mobility revolution, led by electric vehicles and other futuristic modes of transport. But a startup from Gothenburg called Bzzt is taking a more hands-on approach - using Stockholm as its launchpad.

Bzzt offers an Uber-like service, but instead of cars it uses tiny electric mopeds that can travel up to 45 kilometers per hour. The company’s vision is to make taxi services available to everyone in the inner city, by offering prices comparable to public transport.

The podtaxi’s, as Bzzt calls them, resemble an electric tuk-tuk that you would normally expect to see in a Southeast Asian city. They are manufactured by Clean Motion, a company backed by Skype’s founder Niklas Zennström.

A podtaxi can be ordered through the Bzzt-app anywhere within the inner city of Stockholm. The customer only pays for meters travelled, which means a fixed fee of 30 krona ($3 dollars) per kilometer, regardless of traffic.

Global population and urbanization are increasing at a rapid pace. According to UN reports, 54% of world’s population was urban in 2014 and this figure is expected to be 66% by 2050. Global energy demand is expected to follow a similar trend and increase rapidly over the next few decades. Moderate UN scenarios suggest that if current population and consumption trends continue, by the 2030s, we will need the equivalent of two Earths to support us.

Energy is the most important driver of economic growth and as the world moves towards urbanization, the demand for energy is ever increasing in the cities. This provides us with both a challenge and an opportunity to decide the future course of our cities and more importantly the quality of life of citizens of the future. We need to ensure smart sustainable cities for our future generations.

Smart cities must be sustainable in order to survive. Sustainability is a key component of a truly smart city. If you add connectivity to a city without any connection to sustainability issues, you haven't really created a smart city.

To be truly innovative, a city needs to consider elements including renewable energy, smart grids, smart parking and smart transportation. There must be a balance between economy, environment and society to build a strong, resilient city that survives the test of time.

At IoT World 2017 (#IOTW17) in Santa Clara, CA last week, I hosted a panel of leaders who are working within the smart city realm. I asked them about what they've learned in regards to sustainability and smart cities and to share details on some of their projects.

The information they shared with me was highly relevant to smart cities and is useful for any city seeking to become more sustainable.

The falling price of lithium-ion batteries may mean that electrified streets don’t make sense for private cars—but could be useful for public transit.

The prospect of hitting the open road and never having to refuel is a compelling one. And as several new field trials have demonstrated, it’s also increasingly realistic.

The technology, known as inductive charging, is straightforward in theory. A system sets up an alternating electromagnetic field, and then an induction coil in a smaller device harvests power from it. It’s easy enough to make work for small objects that don’t move—some smartphones now offer it as a feature—but transferring enough power to larger, moving objects has proved tricky.
