Agreed, but 2 important things in my eyes.
1 - renewable surpluses. As wind and solar keep ramping , hydrogen is a fantastic way to store that energy. Sure, there are efficiency losses but it’s transportable, able to be stored long term, and able to be used from small scale to grid scale applications.
2 - total life cycle cost. There is an incredible amount of emissions embodied in evs. Haven’t seen a comprehensive analysis of a h2 vehicle but I would imagine a few hundred kilos of missing lithium is a good thing.
Depends.
They’re gps guided 155mm artillery rounds. The electronics and guidance in them reliably survive the 50,000 g-force hell of being shot out of a cannon and then land (when used correctly) within a meter or 2 of their intended target over the course of a 20+km distance.
God knows how much was invested over the years to develop the system, and even once that’s recovered there is still an impressive amount of high precision manufacturing required to make a single one.
I’m positive they’re probably making $30k+ per round, but if it does its job is it worth it?
