            Well, I’m still waiting for the graphene solar panels, cold fusion, flying cars, drone deliveries, metal nanoparticle engines, healing nano bots and what not.

            I wonder if we’re going to build a Dyson sphere before some of those other things become a reality.

              Drone deliveries seemed promising with Amazon, but the core company is so toxic that any tangible product that didn’t come from Lab126 is doomed. Zipline actually has a shot and is actively operating at a massive scale in Rwanda.

      The way to look at these is to not focus on any singular technology. Getting to the point where we have EVs that can go >300 miles on a charge was the combination of lots of breakthroughs over the previous 30 years. Some of what you hear are dead ends, but you only need a few to work out to push things to where they need.

      Broadly speaking, grid storage is a somewhat easier problem to solve than EVs. They care less about mass, and more about cost per MWh.
