The Moore-like downward costs of solar panels and battery backup killed satellite mounted panels, worldwide grids with cables across Pacific and Atlantic oceans, mechanical trackers etc. Seems Singapore is an outlier.
From what I understand Singapore is also connected into a larger Asian grid, albeit mostly running on fossil fuels currently.
So this has extra impact also, as once they unlock Singapore, they could potentially start to push renewables into much more of the grid. So yeah a big deal if they can pull it off, hope they do.
