I’m happy to see this idea continues to develop. I was worried its failure was foregone when Google shuttered their moonshot Makani in 2020. It seems like this iteration is simpler.
for some reason, this always happens with the google moonshots; They come at it from the wrong angle. Someone comes along with a slightly simplier solution after google scrapes the whole thing as uneconomical or beats them to the punch on using a far more technical solution. Don't seem to have a big "Cost per KWH" KPI's internally nor a sense of urgency.
I wonder how Malta is doing. The News blurbs at their website seem... ok?
