Thermal batteries that store solar and wind power
Thermal batteries are yet another way to store an excess of solar and wind power. According to the laws of physics, they would seem to incur major energy losses. But
Iron powder as an energy carrier
The contours of the future energy system haven’t yet been drawn with great precision. Solar and wind energies lie at its foundation. But these come with their problems: at times
Against desertification
Each year, planet Earth loses 13 million hectares (32 million acres) of forest. Since 1960, more than half of all tropical forests have disappeared. Particularly because of logging in the
RethinkX: the new Organizing System
In comparison to most utopian views, RethinkX devotes a lot of attention to the Organizing System required for the transition. It stresses that we cannot just rely on technological innovations.
Transport as a Service
Modesty is not one of the obvious virtues of the RethinkX authors. The subtitle of their report Rethinking Transportation 2020-2030 (May 2017) reads: ‘the disruption of transportation and the collapse
