Sodium batteries are indeed an interesting development, didn’t know it wasn’t so suitable for electric cars.
One thing the video doesn’t mention, and is still a major reason for people to rally to TZM is that it doesn’t mention a different kind of economy. Electric cars and renewable energy are the solution for the wrong question. We try to replace combustion engines, as the woman also says in the conclusion. This is not realistic. There aren’t enough resources to sustain such an infrastructure. We need a different economy, based on localization and doing more with less. Designing more efficient cities, so that people don’t need to own car.
But for some reason, the more obvious the solutions proposed by TZM become, less people are getting interested or involved.
