Electric cars are not THE solution.
We need a clever solution to this problem, because our govts are unlikely to solve this through new infrastructure or policy changes.
I’ve been reading about this topic for a while now, and I always thought the tech these guys invented was worth further investment: https://smarttirecompany.com/
Less rubber is good but we really need a rubber replacement that is biodegradable.
Nickel alloys are expensive and require some nasty mining so shape memory tires are a stopgap solution at best.
Material sciences is a difficult field. People spend years researching one small area just to shelve their research as not viable, too cost prohibitive, or impractical for large scale manufacturing.
I haven’t seen any research into durable biodegradable materials that could hold the weight of vehicles unfortunately, so I think investment will be hard to come by. Though I don’t disagree with the premise that something that can degrade over time, but also not harm the environment would be an ideal solution to the problem. I imagine if such a thing were created it would be able to be applied to many other industries, not just transportation.
