Earth applications are pretty cool, I'm a little negative about using liquids for costs and size/weight etc, but for robustness launch to orbit you can't beat it

I saw one with two gas filled membranes acting as a refractor suspended 100m's apart in space. Thought that had potent for a large scope with low launch costs.
*Though launch per kilo is dropping in recent times
