I was trying to put these sizes in rough perspective. ISS is the largest man-made object in space, which is basically the size of a football field (half a hectare) and cost $150B. https://www.nasa.gov/image-article/comparison-of-size-of-int...

The whitepaper shows a 4km x 4km solar array, which is 1600 hectares (3200 International Space Stations). Would assume the array they're proposing would be cheaper since its structurally more homogenous, but $480 trillion dollars is a whole lot of money.

To be fair, YC says they mostly invest in founders, not ideas. So, expect a pivot at some point.

Aim for orbit, hit aerostat datacenters?
