Interesting takeaways here around the logic behind the Boring Company that weren't clear from the spec video released earlier this week: Cost savings breaks down by: 1) Narrower tubes - less cross-sectional area means cheaper tunneling 2) Continuous tunneling/reinforcing - no stops to build tunnel walls. (Seattle's Bertha did this.) 3) More power = faster execution (not clear on details of this one) Seems not to address different materials/geology in different depths. Also, no mention of regulatory burdens to approve digging underneath existing property rights. (two things I know nothing about)
