nothing in hardware is cheap until it scales up. in fact, the cost vs. scale dynamics are well understood, see Wright's Law.
the "huge assumption" is our entire roadmap... and the major things that drive cost-down are: (1) increased carbon yield by integrating existing pyrolysis technology, (2) shrinking transport distances by operating pyrolysis near injection wells, and (3) increased throughput by making our pyrolyzers larger. these take time, but are hardly shooting for the moon.
