This is something that I would have expected some people on this
list to know about, and have an opinion on, but I don't see any
posts about it for at least the last three years.<br>
<br>
Not sure if the project has stalled for some reason, but does anyone
know anything about it? It seems an excellent idea to me, but
there's no recent blog activity or news on their site. Last blog
entry was 2023/12/16. No hint of even a trial, which surprises me.<br>
<br>
It seems to be a lot cheaper and more efficient than space-based
solar power, would work well at any latitude and all day long, being
above the clouds, and is easily scaleable. The biggest challenge, I
think, would be the tethers, but 20km of vertical cable is not a
problem for current technology. The kinetic storage is a brilliant
idea, I thought, and neatly solves one of the biggest problems that
all solar power systems have.<br>
<br>
Please have a look at the site, and let us know what your thoughts
are. Is there some fundamental problem that they missed? I can't
think of any, except possibly failing to get financial backing, or
political opposition.<br>
<br>
Obviously this idea won't wash in the US, at least for the next four
years, but why hasn't it already gained some traction?<br>
