Cynicism is extremely easy. Every company looks dodgy from the outside and most of them are dodgy. Many such posts turn out to be correct. But that is because cynicism is misplaced - the point of these startups is that some of them will, despite looking dodgy, turn out to be keystones for trillions of dollars of industrial success.
The upside of a serious energy revolution completely outweighs any of these points raised. There needs to be a way for dodgy-looking startups to experiment without just getting a "nah, this year's work is a write off. Oh well lol" from regulators.
