Pierre, we’ve heard that one before from Santos.
“Shooting us down” for not being “high enough”.
All I can say is at least we show substantial power output on meters.
The systems were flying.
Once output from flying contraptions is verified, further development becomes possible.
Yes, yes, we keep hearing about Skysails.
Recent news includes a bankruptcy, and abandonment of their main effort - pulling ships.
Their stories are weak on details and actual data.
One would think if they had impressive data, they would be publicizing it.
One would think if their systems were in regular operation anywhere, we’d see more coverage of such operation. Personally, I’m not convinced. Too many examples of “clean energy breakthrough” vaporware.
Given the small scale and home-built aspects, it’s a decent showing of power output, proving that our concepts at least work.
Demonstrating our craftsmanship at a small scale is a way of avoiding spending too much and declaring bankruptcy. “Professor Crackpot” follows the rule that “We have to build it really big, or people won;t take us seriously!” That paradigm offers multiple excuses, for some, to not build a working demo at all, and for others, when their too-large demo has a single crash, the entire company can be relieved that they can stop pretending and just go bankrupt.
