Quoting from later on in the article:
“If Toyoda is ever to see a car levitate from one of his factories, Toyota’s strategic investment in battery development and the funding of airborne car start-ups will need to pay off. The first part of that, the battery investment, is about to be realised as Toyota Motor is poised to reveal a monumental transition in energy storage for personal mobility by being the first company sell a car to powered by solid-state batteries with a prototype to be unveiled in 2021.”
Nicely done.
